Abstract:

Abstract This paper is focused on the problem of the pollutant source localisation in streams in other words the solution of the inverse problem of pollution spreading with in an extensive open channel network structure, i.e. in a complex system of rivers, channels and creeks in natural catchments or sewer systems in urban catchments. The design of the overall localisation procedure is based on the requirement that the entire localization system be operative and fast enough to enable quick operative interventions and help prevent the spread of pollution. The proposed model, as well as, the overall localisation procedure was calibrated and tested on a real sewer system, which represents in this case an extensive open channel network structure with free surface flow. The test results are successful and confirmed applicability of proposed localization tool in simple real conditions. However, the localisation procedure has pros and cons, which are discussed in the paper.

Abstract:

A numerical model for simulating flows in either sewer or open channel systems is presented. The physical phenomenon of one-dimensional unsteady flow described by the St. Venant flow equations is examined for a more accurate and stable solution under a wide variety of physical conditions experienced in sewer or channel systems. A sparse matrix technique associated with a staggered grid numerical system is developed to solve the flow equations implicitly. Use of this sparse matrix technique leads to a substantial reduction in the order of the sparse matrix and the requirement of computer memory. The model is established without any omission of the terms in the St. Venant equations under the flow and depth conditions experienced in the sewer or open channel systems. The application of the model to a large complex looped sewer system shows that the model achieves a significant improvement in computational speed compared with the USEPA EXTRAN model and can still maintain similar accuracy. The model is especially suitable for real time control purposes since the simulation time of the model is almost negligible in comparison to the real time physical process even for a large looped system. The simulation also shows that base flow is practically not required for the model when the system is dry.

Full text

Abstract:

The paper describes a relatively easy to use computer program for the analysis of steady state surface and energy profiles in networks of open channels. RIVER4 is intended primarily for use in a time-sharing environment to facilitate the trial and error setup and calibration and modification of networks of arbitrary geometry and connectivity. The networks may consist of natural and man-made open channels or sewer systems or both, in configurations of single reach, multiple tributaries, and bifurcated branches with resultant "island" flow. As well as regular reaches, the system description may include transition devices such as bridges, weirs, culverts, manholes, and diversion structures. The flow resistance equation is selected at run time, from six commonly used laws. System geometry is stored on secondary devices such as tapes or discs so that relatively large systems may be analysed in machines of modest size. Key words: backwater, channel, computer, design, flood, islands, networks, profiles, sewers.

Abstract:

Head and pressure changes were studied at manholes with a 90° bend. For pressurized flow, such changes depend only on junction geometry. Among junction parameters, the benching was found particularly important. Full benchings reaching to the pipe crown produced the lowest head losses, particularly when combined with an enlarged pipe diameter at the junction. Head changes in open-channel flow were significantly smaller than those in pressurized flow. Key words: head loss, manholes, sewer junctions, sewer design, sewer hydraulics.

Abstract:

Urban drainage and sewer systems, and channels in general, are treated by the deposition of sediment that comes from water collecting systems, such as roads, parking lots, land, cultivation areas, and so forth, which are all under gradual or sudden change. The carrying capacity of urban area channels is reduced heavily by sediment transport that might even totally block the channel. In order to solve the sedimentation problem, it is therefore important that the channel is designed by considering self-cleansing criteria. Incipient deposition is proposed as a conservative method for channel design and is the subject of this study. With this aim, an experimental study carried out in trapezoidal, rectangular, circular, U-shape, and V-bottom channels is presented. Four different sizes of sand were used as sediment in the experiments performed in a tilting flume under nine different longitudinal channel bed slopes. A shear stress approach is considered, with the Shields and Yalin methods used in the analysis. Using the experimental data, functionals are developed for both methods. It is seen that the bed shear stress changes with the shape of the channel cross-section. Incipient deposition in rectangular and V-bottom channels starts under the lowest and the highest shear stress, respectively, due mainly to the shape of the channel cross-section that affects the distribution of shear stress on the channel bed.

Abstract:

The properties of unsteady open-channel turbulent flow were theoretically and experimentally investigated in a circular cross section channel with fixed sediment deposits. Velocity and turbulence distribution data were obtained using an ultrasonic velocity profiler (UVP). Different uniform flow conditions and triangular-shaped hydrographs were analysed. The hydrograph analysis revealed a dynamic wave behaviour, where the time lags of mean cross section velocity, friction velocity, discharge and flow depth were all evident. The bottom shear stress dynamic behaviour was estimated using four different approaches. Measurements of the velocity distribution in the inner region of the turbulent layer and of the Reynolds stress distribution in the turbulent flow provided the analysed data sets of the bottom shear stress. Furthermore, based on the Saint Venant equation, the bottom shear stress time behaviour was studied using both the kinematic and the dynamic flow principles. The dynamic values of the bottom shear stress were compared with those for the steady flow conditions. It is evident that bottom shear stress varies along the generated flood hydrograph and its variation is the function of the flow unsteadiness. Moreover, the kinematic flow principle is not an adequate type of approximation for presented flow conditions.

Abstract:

The critical depth and normal depth computation are essential for hydraulic engineers to understanding the characteristics of varied flow in open channels. These depths are fundamental to analyze the flow for irrigation, drainage, and sewer pipes. Several explicit solutions to calculate critical and normal depths in different shape open channels were discovered over time. Regardless of the complexity of using these explicit solutions, these formulas have a significant error percentage compared to the exact solution. Therefore, this research explicitly calculates the normal and critical depth in circular channels and finds simple, fast, and accurate equations. First, the dimensional analysis was used to propose an analytical equation for measuring the circular channels' critical and normal depths. Then, regression analysis has been carried for 2160 sets of discharge versus critical and normal depths data in a circular open channel. The results show that this study's proposed equation for measuring the circular channels' critical and normal depths overcomes the error percentage in previous studies. Furthermore, the proposed equation offers efficiency and precision compared with other previous solutions.

Abstract:

Floods in flood-stricken areas have been a major threat to the survival of lives and livelihoods in various aspects. For instance, increased pot-holes, road disconnection and tearing off as well as bridges being carried away have led to increased cases of accidents leading to loss of lives. This has led to Government over-stretching budgetary allocations to cater for maintenance and repair of roads and bridges. This study has developed a model for fluid flow past an open channel with a trapezoidal cross-section with a segment base having lateral inflow channel. The turbulent formation between the lateral inflow channel and the main channel are assumed to be negligible and hence the flow is laminar. The model equations governing the fluid flow are non-dimensionalized and solved using finite-difference method. The numerical values are simulated using Matlab software. It is found that an increase in cross-section area of the lateral channel increases the discharge in the main channel leading to an increase in flow velocity. An increase in surface roughness increases shear stress thereby recording a reduced flow velocity. The findings of this study is highly applicable in the design of drainage systems for road construction, sewer building, street drainage, dams, and airport construction in Kenya and elsewhere. Moreover, the designed efficient channels with optimal dimensions are applicable in draining water to hydro-electric power plants where large volumes of high velocity water are required to turn large turbines for electrical processes.

Abstract:

Many utilities are seeking innovative sewer rehabilitation technologies, particularly for large-diameter pipes. This article describes the demonstration of corrosion testing for a spray-applied geopolymer mortar during the rehabilitation of a 1.5-m (60-in) reinforced concrete pipe ~7.6 m (25 ft) deep in Houston, Texas, USA. The demonstration section was 50.3 m (165 ft) of severely deteriorated pipe that terminated at a wastewater treatment plant. Unique aspects of this project included: (a) use of an innovative and emerging large-diameter structural rehabilitation technology on a severely deteriorated pipe located beneath a large open storm water channel, and (b) an independent, third-party assessment of the technology.

Abstract:

The Parshall flume was designed primarily to monitor the discharge rate in various irrigation channels, dam discharge, municipal sewer flow rate, industrial wastewater discharge, and many other applications, such as indirect measurement of landfill leachate, whereas its secondary use is to aid in increasing the amount of oxygen in a channel. Aeration is the process through which oxygen is exchanged between water and air. A Parshall flume was designed with a converging part, a diverging outflow, and a flat floor, known as a throat with upward slope sections and a downward sloping floor. The main merits of a Parshall flume are its self-cleaning capability, relatively low head loss compared to other open channel hydraulic structures, high self-cleaning capability, and the ability to sustain comparatively high degrees of submergence without impacting the rate of flow. The famous, simple, and original equation of the Parshall flume contains the biggest shortcoming of not considering spatial and temporal variation which leads to insufficient findings and poor maintenance. The modification of the Parshall flume equation depending on climatic and design parameters is important and may be done successfully and efficiently utilizing software modelling. Many researchers have employed various software modelling techniques to improve the computation speed, accuracy, and precision of measurements in the Parshall flume. The main focus of this study is to determine various software modelling techniques used for the measurement of aeration in the Parshall fume and improvement in the Parshall flume equation

Abstract:

The train coasts into Agra, full of tourists coming to visit the newly scrubbed, sparkling white Taj Mahal. Through the window I see dozens of men squatting on the bare, flat ground between the railway tracks and a string of low buildings. Their backs are partially turned to the train tracks. Some squat alone; others hunch near each other in companionable duos. They gaze meditatively into the distance as they relieve themselves on the garbage-strewn ground. I see this lineup for at least a mile as we glide toward the train station in the early morning. Some of the men carry little aluminum pots or plastic bottles as they approach the waste ground. The vessels sit on the ground next to men who are still engaged in their morning ritual. The water is for washing, for this is a land of washers, not wipers. I can’t tell whether or not the train has surprised the men today by its punctuality. No one looks uncomfortable. No one is hurrying. Privacy seems irrelevant to them. And in any case the men’s long white cotton tunics cover most of their bodies. There are no women. Perhaps they came earlier, when it was darker, before there was a chance that the frequently delayed train would catch them. I had not planned for a whole chapter in this book, let alone one right here at the beginning, to be about toilets and bodily functions. But there’s really no avoiding it. Rivers pour clear and clean out of the mountains, then become sewers in the Gangetic plain. One of the biggest problems in South Asia is, simply, what to do with the shit of more than a billion people. Few of them have toilets as Westerners understand the word. Many have nothing at all—no outhouse, no pit latrine. Globally, 1.2 billion people are still defecating in the open, approximately six hundred million of them in India. By 2010 more than half of India’s billion people had access to a cell phone while only a third had some form of toilet to use.

Abstract:

This paper provides a detailed review of different alternate materials being used optimally in asphalt mixes. It demonstrates that various waste materials, including Reclaimed Asphalt Pavement, fly ash, various shells, geopolymer, rubber, scrap tires, plastic waste, bamboo, jute, crushed glass, etc., can be alternatively employed in the production of asphalt mix. In nations such as India, waste generated from different sources is typically subjected to incineration, open burning, disposal into landfills or water bodies, and discharge into sewers. This underscores the potential for utilizing waste as an alternate construction material in pavement development, particularly in developing nations like India, where consumption is high and disposal space is limited. Additionally, the imperative for efficient energy usage and the global concern for climate change make it essential to reduce pollution and enhance recycling and reuse. Therefore, the integration of such practices into civil engineering scenarios is crucial to meet environmental standards. This study assesses the diverse applications of alternate waste in sustainable pavement construction and reviews existing research on the reuse of some waste alternate materials as road construction materials and their sustainability. Further, associated challenges in implementing alternate materials in road construction have been discussed.

Abstract:

Absrract Sewer renewal technologies that are currently used for the repair, replacement and/or rehabilitation of deteriorating wastewater collection systems are generally effective, but there is room for improvement of existing technologies and for the development of new technologies. Many utilities are seeking innovative rehabilitation technologies, particularly for large-diameter pipes. However, information about these emerging technologies is not always readily available. As part of the U.S. Environmental Protection Agency's Aging Water Infrastructure Program, a field demonstration program of innovative rehabilitation technologies was initiated with the purpose of: (1) gathering reliable performance and cost data for new technologies; and (2) making the capabilities of these technologies better known to the industry. This paper describes the demonstration of corrosion testing for a spray-applied geopolymer mortar during the rehabilitation of a 60-inch reinforced concrete pipe approximately 25 feet deep in Houston, TX. The demonstration section was 165 feet of severely deteriorated pipe that terminated at a wastewater treatment plant (WWTP). Unique aspects of this project included: (a) use of an innovative and emerging large-diameter structural rehabilitation technology on a severely deteriorated pipe located beneath a large open stormwater channel; (b) an independent, third-party assessment of the technology; and (c) difficult flow control issues at the WWTP.
