Abstract:
Esso’s Long Island Point facility has been operating for more than 40 years beside Western Port in Victoria, and has discharged treated wastewater and storm water to the bay for most of these years. The 2001 State Environment Protection Policy Schedule F8 for Waters of Western Port is part of Victoria’s Environment Protection Authority’s (EPA) legal framework for licensing discharges to the waters of Victoria, and requires that discharges ‘cause no detrimental change in the environmental quality of the receiving waters, as determined by an environmental monitoring program’. As part of Esso’s ongoing commitment to continuous improvement, a major upgrade to the water treatment facility was completed to further improve the quality of waters discharged to Western Port. In conjunction with this upgrade, Esso is undertaking a study on the effects of the discharge on the environmental quality of Western Port. This peer-reviewed paper presents an example of the practical application of managing discharges to ensure that the stated environmental values of a receiving environment are protected. The environmental study focuses on four key aspects of marine-environment quality relevant to key Western Port ecosystem values in the vicinity of the facility’s effluent discharge, which are: ambient water quality; seagrass biomass; jetty pile epibiota; and, ecological risk through toxicity testing. The study demonstrates the implications of basing regulatory requirements on the quality of the site-specific environmental characteristics, rather than merely effluent quality and generalised water quality objectives. Furthermore, it validates the need for sound science to underpin regulatory limits and industry practices when operating in sensitive environments.

Abstract:
Objectionable odours and flavours in drinking water are a constant concern to consumers and public water suppliers. The organoleptic properties of drinking water can be naturally induced or man-made. In this paper characteristics and causes of odours and flavours are evaluated. Two methods for determining odour and flavour, in relation to the EC Directive 80/778, are described. In the Netherlands, the Netherlands Waterworks Testing and Research Institute (Kiwa) is responsible for the testing and certification of materials used in the production and distribution of drinking water. A study was undertaken to develop standards for odours and flavours in water under well defined conditions. Results of round robin tests in the period 1994 through 1997, demonstrated a considerable improvement in these methods. A valuable strategy is available for a successful localization of the causes of flavours and odours to protect consumers against health risks. Accordingly, these analytical techniques can give a complete view of impurities derived from distribution systems.

Abstract:
This work proposes a methodology specially aimed at Higher Education Institutions (HEIs). The methodology is based on the use of quantitative and qualitative indicators that allow diminishing the assessment’s subjectivity and the uncertainty of the results. This proposal was designed within the implementation of Environmental Management Systems (EMS) according to the ISO standard 14.001/2015, so it can be applied by any kind of organization interested in improving its environmental performance by identifying its environmental aspects, as well as assessing and preventing its environmental impacts. The methodological proposal assesses standard criteria like the affected area and the frequency of the activities that generate the environmental aspects. This analysis is complemented by innovative indicators such as the danger of the substances related to the environmental aspect, the time of exposure and the effects on human health. Additionally, some indicators that allow measuring the magnitude of the harm generated by the identified aspects are also included. The proposed approach has two main advantages: first, it allows integrating the environmental analysis with other management systems, such as the Occupational Health and Safety Assessment Series (OHSAS 18001), quality (ISO 9001) and general requirements for the competence of testing and calibration laboratories (ISO 17025), among others; and second, it establishes an indicators system whose frequent assessment allows following up the environmental aspects and evaluate the effectiveness of its management measures. The application of this methodology in the main seat of Universidad Nacional de Colombia revealed that the most significant environmental aspects were: generation of ordinary solid waste, consumption of potable water, consumption of electric power, generation of recyclable solid waste, and wastewater discharge.

Abstract:
Green roofs can provide environmental benefits that include increased building insulation, mitigating urban heat islands, providing aesthetic value, reducing runoff and storm water flooding in urban environments, improving air quality by sequestering pollutants, cooling photovoltaic panels to improve their function, and providing habitat for fauna and flora. Until very recently, improvements of green-roof environmental services had been achieved largely by horticulturalists, engineers, and architects. In recent years, ecologists have increased their participation, implementing ecological theory for enhancing biodiversity, and selecting specific plant assemblages for other environmental services such as carbon sequestration and for providing cooler roofs. Moreover, ecologists can use green roofs as relatively novel habitats for testing and developing ecological theory. This special issue is devoted to fostering input from ecologists for advancing the environmental and ecosystem services of green roofs. A wide range of ecologists can explore the topic of the ecological aspects of green roof design and implementation including island biogeography theory, niche theory and null models, the role of environmental heterogeneity, invasion ecology, and plant selection. They can contribute ecological methodology and study design for strong inference.

Abstract:
Abstract There is an increasing number of everyday flood incidents around the world, the impact of which poses a challenge to society, the economy and the environment. Under the Water Framework Directive (2000/60/EC), green infrastructure through the use of sustainable drainage systems (SuDS) is the recommended policy to manage and treat storm water runoff. Given the limited published experimental information on permeable interlocking concrete block pavements (PICPs), this paper presents novel results from an experimental laboratory study on a permeable interlocking concrete block pavement rig, investigating the short-term hydrology of the pavement, and water quality aspects related to the retention capacity of suspended solids (SS) through the pavement structure. Results of the volume analysis demonstrate high capability of the permeable structure to reduce the concentration time and attenuate the storm. Water quality testing was employed mainly as an indicator of the tendency of the suspended solids retention by the structure, indicating increasing tendency in the sediment mass retention progressively after each rainfall event. Experimental results obtained in the present study have direct application on the implementation of PICPs in car parking lots, urbanised pavement structures and pedestrianised walkways.

Abstract:
Environmental concerns surrounding drilling for gas are intense due to expansion of shale gas drilling operations. Controversy surrounding the impact of drilling on air and water quality has pitted industry and leaseholders against individuals and groups concerned with environmental protection and public health. Because animals often are exposed continually to air, soil, and groundwater and have more frequent reproductive cycles, animals can be used as sentinels to monitor impacts to human health. This study involved interviews with animal owners who live near gas drilling operations. The findings illustrate which aspects of the drilling process may lead to health problems and suggest modifications that would lessen but not eliminate impacts. Complete evidence regarding health impacts of gas drilling cannot be obtained due to incomplete testing and disclosure of chemicals, and nondisclosure agreements. Without rigorous scientific studies, the gas drilling boom sweeping the world will remain an uncontrolled health experiment on an enormous scale.

Abstract:
This article provides a detailed analysis of the fundamental elements required prior to conducting on-field research of an areas chosen as case studies for the assessment of soil and water quality in the unpolluted zones. The ultimate goal of the research to be carried out over the next two years is to obtain solid and reliable data on the quality of the two environmental components in these areas. All the data obtained will be integrated into a solid and georeference database, consisting of a sample identification module (soil and water) and a module of a varied parameters that will contain up to 42 parameters analyzed in the testing laboratories. Finally, the article presents the conclusions regarding the transposition of the proposed objectives into field and laboratory activities, graphical and descriptive details integrated into a conceptual model, universally valid in order to evaluate protected natural areas without direct anthropogenic impact. Particular importance in assessing these areas is attributed to detailing aspects that can influence the research results in major way. Issues related to the sampling and subsampling of soil and water samples, their conservation and transport to the laboratory are considered relevant and major. Geomorphological criteria of details, geographic and geological information are considered important in assessing the areas chosen as case studies. The five areas selected in the present study have been described and a number of objectives and activities have been proposed for on-site research to be carried out in the near future.

Abstract:
This paper is about Interlocking Stabilized Soil Blocks (ISSB) as developed in Thailand. ISSB are seen as an eco-friendly building material for home building and structures such as water tanks and sanitation facilities. For several decades the Thai R&D Institute TISTR has worked on developing and testing ISSB, which in other countries are called compressed stabilized earth blocks or CSEB. The composition of building blocks and the quality of building structures determine together the structural quality of the house or building. If there is a need for earthquake- and storm resistance, the building blocks and the structures must have specific features. Building stacked houses is an important issue given the growing scarcity of land for housing and the increasing land prices. ISSB is not only applied in Thailand, but also in Cambodia for low-cost housing and in Nepal for home reconstruction after the 2015 earthquake. ISSB or CSEB is also applied in other countries as an alternative building material and technology to replace the use of fired bricks and concrete building blocks for housing. Reducing the use of cement in the materials and structures is important for environmental reasons, but in ISSB/CSEB the use of cement as a stabilizer cannot always be avoided. This is surely the case in areas where earthquakes, heavy storms and floods can occur. Although this paper focuses mainly on technical aspects of sustainable housing and construction, there is also a focus on social sustainability, meaning a strong involvement of local communities in the production of sustainable building materials for walls, newly developed construction technologies, and mutual house and facility construction.

Abstract:
Water quality changes that occur during establishment and maintenance of nitrification in two identical recirculating aquaculture systems containing rainbow trout are described. The time taken for the nitrification process to become established was 40-45 days. Mortality of fish attributed to elevated nitrite concentrations were recorded during the initial conditioning phase of the systems. Un-ionised ammonia concentrations did not attain lethal levels during this period. Nitrate concentrations accumulated slowly throughout the study, while the pH and alkalinity of the water decreased with progressive nitrification. Levels of carbon dioxide, calcium, dissolved and suspended solids remained relatively stable until the carrying capacity of the systems was increased, upon which they increased rapidly and general water quality deteriorated. Permanently elevated concentrations of ammonia and nitrite served as an indication that the carrying capacity of the systems had been exceeded. The use of ozone as a water enhancement treatment in aquaculture systems during one- and six-hour applications was also considered in this study. Ozonation significantly reduced nitrite levels at · low concentrations (0,1 - 0,15 mg/l), although they returned to pre-treatment levels within a few hours of cessation of the treatment. The formation of an unstable, intermediate product that reforms as nitrite in the absence of ozone, rather than the complete oxidation of nitrite to nitrate, is proposed. Ozonation also resulted in decreased dissolved solids, and improved the clarity and odour of the water. Ozone had no effect on ammonia concentrations (at pH > 7,0), or on nitrate or calcium levels, and did not conclusively increase the redox potential of the water. Residual ozone concentrations up to 0,04 mg/l in a sixhour treatment had no harmful effects on rainbow trout, and there were no signs of gas-bubble disease arising from supersaturation of the water with oxygen. Activated carbon filters were effective at removing residual ozone from the water after treatment. Treatment of the water with oxygen alone had no effect on nitrite concentrations.

Microbial water quality analyses were conducted on 15 samples of factory-produced sachet water and 15 samples of hand-tied sachet water, sold in Tamale, Ghana. The tests included the membrane filtration (MF) test using mColiBlue24® medium, 3MTM PetrifilmTM test, and Hydrogen Sulfide Presence Absence (P/A H2S) test. With the MF method, 1 factory-produced and 1 hand-tied sachet-water sample had E.coli counts of 5 CFU/100ml and 49 CFU/100ml respectively. Almost half (47%) of the factory-produced sachet-water samples had some total coliforms (range from 1 CFU/100ml to 115 CFU/100ml). All the 15 hand-tied sachet-water samples had total coliforms (range from 4 CFU/100ml to 2010 CFU/100ml). One sample recorded TNTC at a dilution factor of 10. The MF method showed little correlation with the 3MTM PetrifilmTM method (R=0. 16). With the 3MTM PetrifilmTM test method, none of the factory-produced sachet-water samples had E.coli and only one sample had total coliforms with 100 CFU/100ml. The hand-tied sachet-water sample with 49 E.coli CFU/100ml in the MF test, turned out to have 100 CFU/100ml in the 3MTM PetrifilmTM test. The MF test results were considered more reliable.
(cont.) For the P/A H2S test, 7% of factory-produced sachet-water samples and 27% of the hand-tied sachet-water samples returned positive results. Overall, hand-tied sachet water was found to be two times more microbially contaminated than factory-produced sachet water. Turbidity tests done on the samples showed that 93% of the hand-tied sachet-water samples and 20% of factory-produced sachet-water samples had turbidities greater than 5 NTU - the limit set by the 1998 Ghana Standards for drinking water. Out of 30 random passer-byes in Tamale and neighboring Savelugu that were interviewed, all drank sachet-vended water, signifying its popularity in the areas. For 37%, sachet water formed the sole supply of drinking water, even at home! 70% drank more water when away from home, 20% the same amount at home and away from home, while 10% drank more water at home. Sachet water formed the main source of water away from home. Sachet-water vendors made 100% to 400% profit.

Full text
Abstract:
As the numbers of installed greenroofs continue to grow internationally, designing greenroof growing media to reduce the amount of nutrients in the stormwater runoff is becoming essential. Biochar, a carbon-net-negative soil amendment, has been promoted for its ability to retain nutrients in soils and increase soil fertility. This study evaluated the effect on water quality of greenroof runoff after adding biochar to a typical extensive greenroof soil. Prototype greenroof trays with and without 7% biochar (by weight) were planted with sedum or ryegrass, with barren soil trays for controls. The greenroof trays were subjected to two sequential 2.9 in/hr rainfall events using a rainfall simulator. Runoff from the rainfall events was collected and evaluated for total nitrogen, total phosphorus, nitrate, phosphate, total organic carbon, and inorganic carbon. Greenroof trays containing biochar showed lower quantities of nutrients in the stormwater runoff compared to trays without biochar. Biochar-amended soil with and without plants showed a 3- to 25-fold decrease in release of nitrate and total nitrogen concentrations, as well as a decrease in phosphate and total phosphorus concentrations release into the rainfall runoff. Phosphorus results from trays planted with sedum indicate that sedum interacted with both soils to cause a decrease of phosphorus in the greenroof runoff. In correlation with a visual effect in turbidity, biochar-amended soil showed a reduction of total organic carbon in the runoff by a factor of 3 to 4 for all soil and plant trays. Inorganic carbon was similar for all tests showing that inorganic carbon neither reacted with, nor was retained by, biochar in the soil. The addition of biochar to greenroof soil is an effective way to retain nutrients in a greenroof soil, reduce future fertilizer demands, and improve the water quality of the stormwater runoff by reducing nitrogen, phosphorus, and total organic carbon concentrations in the runoff water.

Abstract:
Although the use of pesticides is necessary to meet the socio-economic needs of many developing countries, especially in Africa, side effects of these bio-active chemicals have contributed to contaminating aquatic and terrestrial ecosystems. Environmental water quality degradation by pesticides interferes with ecosystem health and poses numerous risks to aquatic life. In South Africa, glyphosate-based herbicides are frequently used to control weeds and invading alien plants, but ultimately end up in freshwater ecosystems. However, there are no South African-based environmental water quality management strategies to regulate these bio-active chemicals. Therefore, this study sought to provide a sound scientific background for the environmental water quality management of glyphosate-based herbicides in South Africa, by conducting both laboratory and field investigations. In the laboratory investigations, aquatic ecotoxicological methods were used to evaluate responses of the freshwater aquatic shrimp Caridina nilotica exposed to Roundup® at different biological system scales, and the responses of multiple South African aquatic species exposed to Roundup® through species sensitivity distribution (SSD). In the field investigations, the effect of Kilo Max WSG on the physicochemical and biological conditions of three selected sites in the Swartkops River before and after a spray episode by Working for Water were evaluated through biomonitoring, using the South African Scoring System version 5 (SASS5) as a sampling protocol. Both Roundup® and Kilo Max WSG are glyphosate-based herbicides. All the data were subjected to relevant statistical analyses. Findings of this study revealed that Roundup® elicited responses at different biological system scales in C. nilotica, while SSD estimates were used to derive proposed water quality guidelines for glyphosate-based herbicides in South Africa. The biomonitoring revealed that using glyphosate-based herbicides to control water hyacinth within the Swartkops River had a negligible impact on the physicochemical and biological conditions. Based on these findings, a conceptual framework that can be used for the integrated environmental water quality management of glyphosate-based herbicides in South Africa was developed as part of integrated water resource management (IWRM). The combined data sets contribute to a sound scientific basis for the environmental water quality management of glyphosate-based herbicides in South Africa.

Abstract:
Water samples and macroinvertebrates were collected from three stations of Finley Creek, Indiana before and after a surface cleanup of an adjacent hazardous waste disposal site. Water quality parameters: iron, total dissolved solids, conductance, hardness, total suspended solids and pH were compared between stations and years. The water quality above the landfill was high but decreased downstream. The water below the disposal site contained high levels of chemicals in both studies. However, the concentrations of chemicals were lower in the water two years after the cleanup.Numbers of macroinvertebrates and the number of taxa were determined and species diversity indicies were established. The results showed a statistically significant increase in macroinvertebrate taxa and mean species diversity indicies below the waste disposal site after the cleanup. These results indicate an improvement of water quality.

This thesis accomplishes three tasks. First, it verifies the EC-Kit under different water source conditions by comparing it to a laboratory standard method, the IDEXX Quanti-Tray[tm]. The EC-Kit is a simple, inexpensive field test kit that contains complementary tests for Escherichia coli and total coliform: the Colilert[tm] 10-milliliter presence/absence test and 3MTMS Petrifilm[tm] test. This work was executed by analyzing 521 water samples collected in Capiz Province, Philippines as well as 40 water samples from the Charles River in Cambridge, Massachusetts. Second, it determines the risk level for drinking water sources according to E.coli and total coliform levels in Capiz Province for difference locations and source types. Third, this study contributes to an ongoing mapping project, aimed at creating an interactive, searchable map of water quality results from EC-Kit and Quanti-Tray[tm]. The results of the study reveal that each component of EC-Kit and the entire kit itself is correlated to Quanti-Tray[tm] in a statistically significant way. Moreover, from the calculations of error and proportional reduction in error for unimproved/improved water sources, it is possible to make better predictions with just the use of the Colilert[tm] test, but not just the use of the TM T Petrifilm . This is because the detection limits for PetrifilmTM are an order of magnitude higher than Colilert[tm], namely PetrifilmTM colony counts of 1-10/1 mL sample results fall within the High and colony counts of 10-100/1 mL of sample fall within the Very High risk level categories, whereas positive Colilert[tm] results fall within the Intermediate, High, and Very High risk level categories. Most importantly, the EC-Kit allows for the best reduction in error, with a proportional reduction in error of 63% for unimproved water sources and 60% for improved water sources. This finding is significant because it means that a simple, inexpensive field kit can change our understanding of the safety of drinking water compared to simply knowing the United Nations infrastructure designation of improved versus unimproved water sources. Furthermore, the statistical analysis revealed that while the EC-Kit does not exactly match the Quanti-Tray[tm] results, it still provides useful information for assessing at-risk water sources.

Abstract:
Forest clearance can affect the levels of dissolved organic carbon (DOC), nutrient concentrations and algal biomass in streams, but the possible effect of these inputs on downstream lakes is usually surmised rather than demonstrated. To evaluate the effect of forest clearance on DOC and nutrient cycling in lakes, DOC, total phosphorus (TP), total nitrogen (TN) and chlorophyll (chl a) concentrations were measured in 47 Canadian Shield lakes in Quebec. Of these lakes, 25 were located in drainage basins that were partially clear-cut one to four years previously. In the disturbed sites, an uncut 20-m bufferstrip was left around the lakes and permanent water courses.
To account for differences among the watersheds that are not related to forest harvesting, I also collected a series of catchment and morphometric variables (watershed area, lake area, drainage ratio, forest, wetland, and upstream lake area, watershed slope, water residence time and lake depth). Lake characteristics in undisturbed and disturbed watersheds were compared to determine if forest clearance has a detectable effect on the water quality of downstream lakes. Although comparisons of seasonal and monthly means of the water quality variables between disturbed and reference sites were inconclusive, likely because of high natural variability, the size of the clear-cut was significantly related to means of the water quality characteristics. DOC, TP, TN and chl a increased in lake water with the area of the clear-cuts when large portions of the watershed ($>$50%) were cleared. The results of this study suggest that logging has an effect on water quality and even though a bufferstrip of twenty meters reduces this effect largely, it may not be enough to provide complete protection against the effects of logging activities.

Abstract:
Abstract 'Quality' of greenhouse and hydroponic produce implies suitability for a particular purpose or the degree to which certain set standards are met. Aspects of produce quality may encompass sensory properties (appearance, texture, taste and aroma), nutritive values, chemical constituents, mechanical properties, functional properties and defects. Quality standards and testing methods have been developed for most commercial crops to help ensure consumers receive produce of a suitable standard. These quality standards can range from basic grading for removal of damaged produce and for size, shape, weight and overall appearance, to analytical testing for compositional factors such as acidity, volatiles, dry matter, starch and sugars, toxins, vitamins and minerals, and others. This chapter discusses the components of crop quality, quality improvement, cultural practices to improve greenhouse produce quality (nutrient solution electrical conductivity levels, salinity and deficit irrigation), environmental conditions (including light and temperature) affecting quality of greenhouse crops, role of genetics in the quality of greenhouse-grown produce, microbial quality and food safety. Different quality testing and grading methods are described such as colour analysis, total soluble solids (Brix) testing, sensory evaluation of compositional quality, volatiles testing (aroma), texture and firmness quality assessment.

Abstract:
Abstract Activated concrete represents the greatest volume of radioactive materials produced during the dismantling operations of a PWR reactor. For heavy barytes concrete, 133Ba is the dominating γ nuclide whereas in the rebars, it is the 60Co isotope. During the dismantling of the BR3 PWR reactor, we studied various aspects of the radioactive concrete issue: • the characterization of the activation depth and its modelization; • the efficiency of various demolition techniques and their application on real scale mock-ups; • the active testing and use of various dismantling and demolition techniques among which the remote controlled jack hammer and the diamond cutting techniques were the most extensively used. As alternative to the conditioning of the radioactive concrete as radioactive waste using the classical cement embedding strategy, we started an extensive R&D programme on the the recycling of the radioactive concrete. The basic idea is to perform a pretreatment of the radioactive concrete so that it can be re-used as aggregates for the fabrication of “radioactive grout”. This grout is then used for the conditioning of metallic radioactive waste. We demonstrated that it is technically feasible to prepare a good quality grout using heavy radioactive concrete as raw material mixed with fresh cement.

Full text
Abstract:
Large hydrostatic test programs require extensive pre-planning to avoid increased costs and delayed schedules. Recently, Enbridge Pipelines Inc. completed construction and testing of more than 1,200 km of an NPS 36 oil pipeline for the Line 4 Extension Project and the Canadian portion of the Alberta Clipper Expansion Project over three construction seasons. A total of 57 mainline hydrostatic tests were successfully completed and approved by the National Energy Board. Following the first construction and hydrostatic testing season, many lessons were learned that were implemented for hydrostatic testing during the second construction season. The most important aspect of large pipeline hydrostatic test programs is locating and securing water sources. Extensive ground truthing must be preformed to adequately determine locations, volumes and access to water sources. Once potential sources are identified, water quality and environmental issues must be assessed, which leads to applying for and obtaining the necessary permits for water withdrawal and discharge. Leaving an important item such as water sources to be “field-determined” can lead to unanticipated complications, schedule delay and increased construction costs. Water sources are just one of the many important pre-planning activities that must be given adequate attention before the start of pipeline construction to successfully and efficiently manage a large pipeline hydrostatic test program. Many projects only complete high-level desktop-based hydrostatic test planning during the detailed design phase of a project. However, the potential cost and schedule impacts far outweigh the extra costs required to complete proper pre-planning during the detailed engineering phase of a project.

Abstract:
The Environmental Laboratory (EL) and the Coastal and Hydraulics Laboratory (CHL) have jointly completed a number of large-scale hydrodynamic, sediment and water quality transport studies. EL and CHL have successfully executed these studies utilizing the Geophysical Scale Transport Modeling System (GSMB). The model framework of GSMB is composed of multiple process models as shown in Figure 1. Figure 1 shows that the United States Army Corps of Engineers (USACE) accepted wave, hydrodynamic, sediment and water quality transport models are directly and indirectly linked within the GSMB framework. The components of GSMB are the two-dimensional (2D) deep-water wave action model (WAM) (Komen et al. 1994, Jensen et al. 2012), data from meteorological model (MET) (e.g., Saha et al. 2010 - http://journals.ametsoc.org/doi/pdf/10.1175/2010BAMS3001.1), shallow water wave models (STWAVE) (Smith et al. 1999), Coastal Modeling System wave (CMS-WAVE) (Lin et al. 2008), the large-scale, unstructured two-dimensional Advanced Circulation (2D ADCIRC) hydrodynamic model (http://www.adcirc.org), and the regional scale models, Curvilinear Hydrodynamics in three dimensions-Multi-Block (CH3D-MB) (Luong and Chapman 2009), which is the multi-block (MB) version of Curvilinear Hydrodynamics in three-dimensions-Waterways Experiments Station (CH3D-WES) (Chapman et al. 1996, Chapman et al. 2009), MB CH3D-SEDZLJ sediment transport model (Hayter et al. 2012), and CE-QUAL Management - ICM water quality model (Bunch et al. 2003, Cerco and Cole 1994). Task 1 of the DOER project, “Modeling Transport in Wetting/Drying and Vegetated Regions,” is to implement and test three-dimensional (3D) wetting and drying (W/D) within GSMB. This technical note describes the methods and results of Task 1. The original W/D routines were restricted to a single vertical layer or depth-averaged simulations. In order to retain the required 3D or multi-layer capability of MB-CH3D, a multi-block version with variable block layers was developed (Chapman and Luong 2009). This approach requires a combination of grid decomposition, MB, and Message Passing Interface (MPI) communication (Snir et al. 1998). The MB single layer W/D has demonstrated itself as an effective tool in hyper-tide environments, such as Cook Inlet, Alaska (Hayter et al. 2012). The code modifications, implementation, and testing of a fully 3D W/D are described in the following sections of this technical note.
