Abstract:
When pseudostatic method is employed to analyze slope seismic stability of high earth- rock dams, earthquake load is computed according to dynamic seismic coefficient figure in the present Specifications for Seismic Design of Hydraulic Structures (DL5073-1997). The figure is only suitable for earth-rock dams lower than 150m. While at the present time, many earth-rock dams to be constructed are higher than 150m. Compared with low dams, high order self-vibrating period of high dams is easy to coincide with seismic predominant period, and high order vibrations are constantly to be activated and amplified, which result in seismic acceleration distribution is different from low dams. With analytical and finite element method respectively, seismic acceleration distribution of high earth-rock dams is analyzed. Suggested dynamic seismic coefficient figure of earth-rock dams 300m-level in height is put forward, which offer a supplement for the present Code for Seismic Design of Hydraulic Structure.

Abstract:
A comparative method for estimating the stress-strain state of earth dams under the effect of static load is given in the paper using spatial and plane-strain models. The results of assessment of stress-strain state of several earth dams using these methods are given. Analysis of the results obtained allows us to conclude that a plane calculation model gives results almost identical to the ones obtained with spatial model; in future that can be the basis for developing recommendations on the use of certain calculation models. Some features of stress state in a spatial case are revealed, indicating the occurrence of dangerous areas with the greatest stresses.

This paper presents an experimental study of a homogenous earth dam. The work is focused to the search of solutions of problems encountered in the earth dams after their construction. One of the major problems is the choice and design of systems of drainage. The effective drainage system to prevent harmful accumulations of excess water is one of the most important roles of dams. Efficient drainage systems can improve the safety of earth dams. The paper presented herein reports the results obtained from the experimental study. Empiric relations have been obtained which can be help in the control of the flow rate in the chimney drain of the earth dams on pervious foundation, which can increase safety earth dams

Abstract:
It can be a great expense to examine individually the stability of earth and rockfill dams on rapid drawdown in civil engineering practice. The aim of this present work is to clarify the safe type on the rapid drawdown among the most common types of earth and rockfill dams and to introduce cheaply the types in dam design. First, a transient analysis of saturated-unsaturated seepage coupled with stress is carried out in the cross sections of typical earth and rockfill dams the during rapid drawdown, and the safety factors of the upstream slopes are determined by the shear strength reduction method. Then, the typical dams are compared for the stability characteristics so that designers can select the safe type of earth and rockfill dams on rapid drawdown. The obtained results show that the decreasing rate of safety factor in a central core dam is 0.72–0.85 times than one of the homogeneous dams and 0.17–0.40 times than one of the sloping upstream core dams so that it is more stable than other earth and rockfill dams during rapid drawdown.

The study of slope stability is important in the design and construction of the earth dams under influence of special states. Some factors affect on the slope stability for the earth dams such as change the water level in the reservoir, dam configuration, material properties..etc. In this study, the factor of safety of upstream slope stability for number of exist earth dams has been assessed. To achieve the objective of this study, Geo-SLOPE/W program that based on limit equilibrium methods was used. Taking into account the case of dry condition and gradually rise of water level in upstream part for these dams. It can be seems that the slope stability of the earth dams increased in case of dry condition. In addition, the slope stability increased when the water reach to maximum value.

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIRO
Uma das atividades relacionadas à recuperação de barragens envolve o alteamento de barragens existentes, normalmente com o objetivo de aumentar a capacidade de armazenamento dos reservatórios, melhorar o fator de segurança dos taludes ou a proteção da estrutura contra possíveis cheias. O alteamento pode estar previsto no projeto original da barragem, mas na maioria dos casos trata-se de um novo estudo, com a barragem em operação, devendo-se verificar as novas condições de fluxo, efeitos na estabilidade de taludes e na resposta da barragem a carregamentos estáticos e sísmicos, estes principalmente em regiões de alta sismicidade, como no sul do Peru, onde se enontram a barragem de terra de Viña Blanca, aqui considerada. Nesta dissertação o método dos elementos finitos e o método de equilíbrio limite, isolada ou conjuntamente, são empregados para análise estática e dinâmica destas barragens de terra considerando diversas opções de alteamento, como a construção de muros parapeito, muros de gabião, solo compactado, solo reforçado com geotêxteis e solo reforçado com revestimento de concreto. De estudos de perigo sísmico efetuados no local das barragens, selecionou-se o valor de aceleração horizontal máximo para ser utilizado nos registros de aceleração ocorridos nos terremotos de Lima (1974) e de Moquegua (2001). As análises numéricas efetuadas mostram que as opções de alteamento consideradas não alteram significativamente as condições de segurança das barragens existentes, tanto do ponto de vista hidráulico como da estabilidade de taludes e resposta dinâmica durante a incidência de terremotos.
One of the activities related to dam constructions involves the raising of the existent structure, normally done with the objective of increasing the water storage capacity of the reservoirs, improving the safety factor of the embankment slopes or to ensure a better protection against possible water flooding. The raising of an earth dam can be predicted in the original dam plan, but in mostly situations consists of a new design, with the dam fully operational, where the effects of a new dam height and reservoir level should be assessed with respect to flow conditions, stability of the embankment soil slopes and the response of the revised structure under static and seismic loads, mainly in highly seismic regions, as in the South of Peru where the earth dam of Viña Blanca, herein studied, was constructed. In this dissertation, the finite element method and the limit equilibrium method were used for the static and dynamic analyses of these earth dams, in their original geometry as well after dam raising with reinforced soil, compacted soil and concrete or gabion structures, among other options. From studies of seismic risk analyses carried out at the dam sites, the value of maximum horizontal acceleration equal to 0.4g was chosen to be used as the peak acceleration in the Lima (1974) and Moquegua (2001) acceleration time histories. The numerical results indicate that all dam raising options investigated in this work do not affect the safety conditions of the dams significantly, either under the point of view of the hydraulic behavior as well as soil slope stabilities or the dynamic response of the earth dams to seismic loads.

Abstract:
Despite 'modern' construction and management techniques, flood embankment and embankment dam failures occur almost routinely around the world. The need to understand, predict and prevent the breaching process remains a high priority for owners and flood risk managers alike. This research provides new understanding and improved methods for predicting breach initiation and growth through earth flood embankments or dams. The improvement of breach model accuracy has made slow progress over the past 20 years, with confusion around breaching processes arising from a lack of appreciation of soil mechanics interacting with hydraulics and structural behaviour. The prediction of different breach processes requires the integration of techniques from all three disciplines. This thesis makes advances from earlier work (Mohamed, 2002) to produce a predictive breach model intended for industry application. The research develops improved approaches for flow calculation, sediment erosion and structural response for predicting breach initiation and growth and uses field data, including video footage, from the EU IMP ACT project and large scale test and case study data from collaboration with the International Dam Safety Interest Group breach modelling project.

Abstract:
Many earth dams around the world are located in zones characterised by moderate to high seismicity. Their seismic stability can be particularly critical for the safety of the areas in the downstream side and therefore an in depth understanding of their response during earthquakes is required. This thesis describes a numerical study related to both the seismic response and analysis of earth dams using the finite element method. In the first part of the thesis, the effect of the upstream reservoir hydrodynamic pressures on the elastic seismic response of dams is explored. Firstly, a methodology is proposed in which the reservoir domain is modelled with finite elements focusing in particular on the accurate prediction of the hydrodynamic pressures on the upstream dam face. Secondly, a parametric study of dam-reservoir interaction is carried out to examine the effect of the reservoir on the seismic response of dams. The second part of the thesis is concerned with the nonlinear seismic behaviour of earth dams. Firstly, a well-documented case study, the La Villita dam in Mexico, is analysed in order to validate the numerical model and a good agreement is obtained between the recorded and predicted data. Subsequently, using as a reference the calibrated model, parametric studies are performed in order to obtain a better insight into the dynamic response and analysis of earth dams. The latter studies provide a means to assess the effect of different modelling considerations on the seismic analysis of dams.

Abstract:
Les barrages sont des ouvrages induisant des risques significatifs, dont leur rupture peut entraîner des conséquences dramatiques en termes de pertes humaines et matérielles. L'érosion interne représente une préoccupation majeure, étant responsable de près de 50 % des défaillances des barrages en terre. Traditionnellement, l'évaluation de la sécurité structurelle de ces ouvrages reposait sur des méthodes déterministes ou semi-probabilistes. Plus récemment, des approches probabilistes ont été développées pour analyser les risques associés aux barrages. Néanmoins, évaluer le mécanisme d'érosion interne des barrages reste un défi en raison des incertitudes liées à l'évaluation des contraintes hydrauliques dues aux écoulements internes aux ouvrages et à l'évaluation des propriétés de résistance des sols.Dans ce contexte, l'objectif principal de cette thèse est de développer une approche probabiliste pour évaluer la fiabilité des barrages en remblai concernant le mécanisme d'érosion interne. Cette étude se concentre principalement sur les aspects suivants : 1) l'établissement d'un modèle hydraulique probabiliste spacialisé à partir de champs aléatoires pour représenter les écoulements au sein d'un barrage en remblai, prenant en compte les différentes incertitudes des propriétés de résistance des sols, 2) la proposition d'une analyse probabiliste pour l'initiation du mécanisme d'érosion régressive au sein d'un barrage en remblai et 3) la proposition d'une analyse complète des mécanismes d'érosion interne, en les appliquant à un cas concret de barrage, afin d'évaluer la sécurité vis-à-vis de l'érosion interne, en prenant en compte différents mécanismes d'érosion tels que : l'érosion régressive, la suffusion et l'érosion par contact.Le manuscrit de cette thèse représente une contribution précieuse aux études probabilistes existantes sur les barrages en remblai. Il fournit aux scientifiques et aux ingénieurs des informations utiles sur les résultats obtenus, facilitant ainsi une résolution plus efficace des problèmes géotechniques concrets dans un cadre probabiliste
Dams are structures involving significant risks. The failure of a dam can lead to dramatic consequences in terms of human and material losses. Internal erosion is a major concern, responsible for almost 50% of earth dam failures. Traditionally, the assessment of the structural safety of these structures was based on deterministic or semi-probabilistic methods. More recently, probabilistic approaches have been developed to analyze the risks associated with dams. However, evaluating the internal erosion mechanisms of dams remains a challenge due to the uncertainties linked to the evaluation of hydraulic stress due to seepage and the evaluation of the soil strength properties to internal erosion.In this context, the main objective of this thesis is to develop a probabilistic approach to assess the reliability of embankment dams regarding the internal erosion mechanism. This study mainly focuses on the following aspects:1) the establishment of a probabilistic hydraulic model spatialized from random fields to represent the flows within an embankment dam, taking into account the different uncertainties in the resistance properties of the soil, 2) the proposal of a probabilistic analysis for the initiation of the backward erosion mechanism within an embankment dam and 3) the proposal of a complete analysis of the internal erosion mechanisms by applying them to a real dam case in order to assess the safety against internal erosion, taking into account different internal erosion mechanisms such as backward erosion, suffusion and contact erosion.This thesis manuscript represents a valuable contribution to existing probabilistic studies of embankment dams. It provides scientists and engineers with useful information on the results obtained, thus facilitating more efficient resolution of practical issues within a probabilistic framework

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR
O presente trabalho apresenta o desenvolvimento de um procedimento numérico para a análise sequencial estática e dinâmica de barragens de terra, durante as principais fases da vida da estrutura:construção, enchimento do reservatório e carregamentos sísmicos. A modelagem numérica é feita mediante o método dos elementos finitos, incorporando as não linearidades dos materiais através de módulos dependentes do nível de tensões, para a análise estática, e do nível de deformações para a análise dinâmica. Inicialmente são apresentadas as características do comportamento de barragens de terra submetidos a carregamentos estáticos e dinâmicos. Apresentam-se também alguns dos fatores que influenciam a resposta estática e dinâmica deste tipo de estrutura geotécnica. Em seguida apresentam-se as formulações e implementações numéricas realizadas para a análise sequencial, estática e dinâmica, por elementos finitos. Desenvolveu-se neste trabalho um programa de microcomputador para análise de barragens considerando varias opções como elementos infinitos, elementos de interface, contornos viscosos, etc. Outras obras de terra e problemas geotécnicos, além de barragens, podem também serem analisadas por este programa, de caráter bastante geral. Finalmente ilustra-se a aplicabilidade do programa e procedimentos implementados, através da previsão do comportamento da Barragem de Recreta, localizada no Peru. Os resultados desta análise, considerando no estudo dinâmico o registro disponível do terremoto de Lima (1974), são apresentados e discutidos.
This work presents the development of numerical procedures for static and dynamic sequential analysis of earth dams during the main phases of their life: construction, reservoir filling and seismic loading. The numerical modeling is performed using the finite element method with material modulus that exhibit either stress state (static analysis) or strain state (dynamic analysis) dependency. General behavior characteristics of earth dams subjected to static and dynamic loads are initially presented. The main factors influencing the static and dynamic responses are also indicated e briefly discussed.Mathematical formulations and the numerical algorithms considered in the development of a computer code specially written for this research, such as interface elements, infinite elements, viscous boundaries, etc., are fully described with several illustrative examples to validate their application. The prediction of both static and dynamic responses of the Recreta Dam, in Peru, is also carried out considering the available seismic records of the Lima earthquake, occurred in 1974. The computed numerical results indicate that the computer program is reliable, efficient and potentially useful for other geotechnical applications.

Abstract:
There are many small earth dams perched high above the floor of the Okanagan Valley in British Columbia. These dams pose a potential risk for destructive debris flow generation if they become breached. A relatively small outburst can trigger a much larger volume debris flow downstream of the dam. The failure of the Testalinden dam in the southern Okanagan region in June 2010 clearly demonstrated the destructive power of a debris flow triggered by the water released by a breach through a poorly maintained dam. Homes were destroyed and property was damaged. This thesis presents a methodology for preliminary assessment of potential debris flow initiation hazards caused by the breaching of small earth dams using digital elevation models, available maps, and limited monitoring records of dams. Research can assist dam safety officers in better ranking the consequences of dam failure. Empirical equations are used to predict the peak outflow if a breach occurs in a small earth dam. The creek gradient and the estimated height of water or outflow per unit width in the creek channel resulting from the outflow are used in debris flow initiation criteria to delineate possible locations along a creek where a debris flow may initiate. If debris flow initiation were possible, this would trigger the need for more detailed assessment of dam failure consequences and will likely result in a higher dam failure consequence classification compared to consideration of flooding only.

Abstract:
A dam is a structure constructed across a river or stream to store water upstream from the obstruction. Dams are susceptible to damage for various reasons, which can lead to many catastrophic disasters. Therefore, identifying the dam's structural failures prior to a disaster is crucial. Drilling can be used for dam failure identification. But it is costly and destructive. Integrated geophysical methods have always helped in identifying subsurface features. In the current investigation, the applicability of ground penetrating radar (GPR) to detect potential failures in earthen dams was assessed. The Uyanwatta Lake earthen dam was selected as the study area during this investigation, considering the reported water leakage in this dam. A GPR survey was conducted with 100 MHz and 300 MHz antennas along five survey paths. Those are the top of the dam, 1.5 m below the top of the dam, and three distinct paths for the lake's spill. During the interpretation process, clay layers, fractured zones, gravel layers, and water seepage areas were identified. Those water leakage areas indicate that there has been a leak in the dam. Those results were compared with exploratory drill hole data from the Uyanwatta Lake Dam. Drill hole data has only presented information about the rock types present in the dam. But GPR data was able to provide information on loose sediments in the shallow depths of the dam as well. That indicates GPR data has the potential to provide additional information related to earthen dams.

Abstract:
Rationale. Earth scent is the odour emitted from soils. This scent, primarily comprising the alcohols geosmin and 2-methylisoborneol (MIB), has not been fully characterised, but offers high potential for use as an environmental interrogation tool. Methodology. We utilised our field- based, solid-phase microextraction fibre method to test the hypothesis that soil activity and soil property variation can be detected in situ by comparing biogenic volatile emissions. Results. We eliminated sources of error utilising field-based sampling with these fibres, concluding that room temperature storage for up to 7 days is acceptable with minimal loss. Variation in individual fibre affinity for both compounds was higher than expected but no measured concentrations were observed to constitute outliers. Disturbance of minor soil volumes led to significantly higher emission of both compounds over background levels. Soil texture and soil cover had a significant effect on the emission of both compounds. Simulated rainfall, producing the characteristic odour known as petrichor, initiates elevated emission of geosmin. Background (undisturbed soil) concentrations of MIB were occasionally detectable during some sampling events, but geosmin concentrations in the air were always below detection limits without soil disturbance. Virtually all background and disturbed soil samples contained much higher concentrations of MIB compared to geosmin, but geosmin variation between replicates and experimental units was much lower. Discussion. Soil disturbance and soil property variation can be remotely detected using emission of volatile compounds. Correlating emission from the soil with respect to disturbance events and environmental properties could yield a powerful new tool for acquiring soil information.

Abstract:
In the article on the material of the Salzburg weekly «New Days» (1945–1947) various spheres of activity of Peter Volyniak are presented. It is noted that this edition was a business card of the publishing house of the same name and had a history of continuation: in Toronto Petro Volyniak restored the publishing house of the same name and continued the publication in the format of the universal monthly «New Days» (1950–1969). The article also presents periodicals («Latest News», «New Days», «Timpani», «Our Way») and literary, artistic and scientific collection «Steering Wheel», which were published in the Salzburg publishing house of Peter Volyniak «New Days». The purpose of the publication is to trace the path of Petro Volyniak from a writer to a literary critic, journalist and publisher. This trend is reproduced in chronological order. Peter Volyniak as a writer is informed in the article «Literary Evening of P. Volyniak» (author – M. Ch-ka). O. Satsyuk’s literary-critical article is devoted to the coverage of ideological and artistic aspects of Petro Volyniak’s collection «The Earth Calls» (Salzburg, 1947). Petro Volyniak as a literary critic is presented in an article devoted to a collection of literary tales by A. Kolomiyets (Salzburg, 1946), which was published by «New Days». Petro Volyniak as a journalist presents the essay «This is our song…». With the help of content analysis it was observed that the text is divided into two parts: the first contains the author’s reflections on the Ukrainian song, its role in the life of the Ukrainian people; in the second, main, Peter Okopny’s activity abroad is presented. The publisher Petro Volyniak in 1947 in a separate publication of the February issue of the weekly summarizes the third year of activity, providing statistics on the publication of periodicals, books, postcards, calendars, various small format materials. The analyzed material demonstrated the experience of combining creative work and commercial activity.

Abstract:
The Geo-mapping for Energy and Minerals (GEM) and Targeted Geoscience Initiative (TGI) programs conducted extensive collaborative research on mineral systems with iron oxide-copper-gold (IOCG) and affiliated deposits in prospective settings of Canada. Regional alteration mapping as well as geochemical and geophysical modelling undertaken under the GEM program documented the evolution of polymetallic metasomatic systems with iron-oxide and alkali-calcic alteration and led to an increased recognition of the mineral potential of poorly explored areas and historic deposits of the Great Bear magmatic zone in the Northwest Territories, thus providing a solid framework for exploration. Early and barren albitite corridors form across the mineral systems and locally host uranium mineralization associated with telescoping of alteration facies by tectonic activity during the metasomatic growth of the systems. Subsequent to albitization, high-temperature Ca-Fe and Ca-K-Fe alteration form iron oxide-apatite (± rare-earth element) mineralization and IOCG variants rich in cobalt and other critical metals, respectively. Systems that further mature to K-Fe alteration form IOCG mineralization and can evolve to mineralized near-surface phyllic alteration and epithermal caps. Transitional facies also host polymetallic skarn mineralization. Rare-earth element enrichments within iron oxide-apatite zones are strongest where remobilization has occurred, particularly along deformation zones. The TGI projects documented the pertinence for a GEM activity in the Great Bear magmatic zone and subsequently synthesized GEM geoscientific data into a system-scale, ore-deposit model, and outlined criteria for mineral resource assessment. This model, and newly developed field-mapping and lithogeochemical tools were shown to be efficient mineral exploration and regional mapping methods in Canada and were also applied to the archetype IOCG deposit, Olympic Dam, and other deposits in the Olympic Cu-Au metallogenic province of Australia. Case examples also include the Romanet Horst in the Trans-Hudson Orogen (second phase of GEM), the Central Mineral Belt in Labrador (TGI), the Wanapitei Lake district in Ontario (private sector exploration results used by TGI), and the Bondy gneiss complex in Quebec (TGI).

Scholz, Florian. Sedimentary fluxes of trace metals, radioisotopes and greenhouse gases in the southwestern Baltic Sea Cruise No. AL543, 23.08.2020 – 28.08.2020, Kiel – Kiel - SEDITRACE. GEOMAR Helmholtz Centre for Ocean Research Kiel, November 2020. http://dx.doi.org/10.3289/cr_al543.

Full text
Abstract:
R/V Alkor Cruise AL543 was planned as a six-day cruise with a program of water column and sediment sampling in Kiel Bight and the western Baltic Sea. Due to restrictions related to the Covid-19 pandemic, the original plan had to be changed and the cruise was realized as six oneday cruises with sampling in Kiel Bight exclusively. The first day was dedicated to water column and sediment sampling for radionuclide analyses at Boknis Eck and Mittelgrund in Eckernförde Bay. On the remaining five days, water column, bottom water, sediment and pore water samples were collected at eleven stations covering different types of seafloor environment (grain size, redox conditions) in western Kiel Bight. The data and samples obtained on cruise AL543 will be used to investigate (i) the sedimentary cycling of bio-essential metals (e.g., nickel, zinc, and their isotopes) as a function of variable redox conditions, (ii) the impact of submarine groundwater discharge and diffusive benthic fluxes on the distribution of radium and radon as well as greenhouse gases (methane and nitrous oxide) in the water column, and (iii) to characterize and quantify the impact of coastal erosion on sedimentary iron, phosphorus and rare earth element cycling in Kiel Bight.

Abstract:
In the early morning on the 4th of August 2014, a tailings dam near Quesnel, BC burst, spilling approximately 25 million m3 of runoff containing heavy metal elements into nearby Quesnel Lake (Byrne et al. 2018). The runoff slurry, which included lead, arsenic, selenium, and vanadium spilled through Hazeltine Creek, scouring its banks and picking up till and forest cover on the way, and ultimately ended up in Quesnel Lake, whose water level rose by 1.5 m as a result. While the introduction of heavy metals into Quesnel Lake was of environmental concern, the additional till and forest cover scoured from the banks of Hazeltine Creek added to the lake has also been of concern to salmon spawning grounds. Immediate repercussions of the spill involved the damage of sensitive environments along the banks and on the lake bed, the closing of the seasonal salmon fishery in the lake, and a change in the microbial composition of the lake bed (Hatam et al. 2019). In addition, there appears to be a seasonal resuspension of the tailings sediment due to thermal cycling of the water and surface winds (Hamilton et al. 2020). While the water quality of Quesnel Lake continues to be monitored for the tailings sediments, primarily by members at the Quesnel River Research Centre, the sample-and-test methods of water quality testing used, while highly accurate, are expensive to undertake, and not spatially exhaustive. The use of remote sensing techniques, though not as accurate as lab testing, allows for the relatively fast creation of expansive water quality maps using sensors mounted on boats, planes, and satellites (Ritchie et al. 2003). The most common method for the remote sensing of surface water quality is through the use of a physics-based semianalytical model which simulates light passing through a water column with a given set of Inherent Optical Properties (IOPs), developed by Lee et al. (1998) and commonly referred to as a Radiative Transfer Model (RTM). The RTM forward-models a wide range of water-leaving spectral signatures based on IOPs determined by a mix of water constituents, including natural materials and pollutants. Remote sensing imagery is then used to invert the model by finding the modelled water spectrum which most closely resembles that seen in the imagery (Brando et al 2009). This project set out to develop an RTM water quality model to monitor the water quality in Quesnel Lake, allowing for the entire surface of the lake to be mapped at once, in an effort to easily determine the timing and extent of resuspension events, as well as potentially investigate greening events reported by locals. The project intended to use a combination of multispectral imagery (Landsat-8 and Sentinel-2), as well as hyperspectral imagery (DESIS), combined with field calibration/validation of the resulting models. The project began in the Autumn before the COVID pandemic, with plans to undertake a comprehensive fieldwork campaign to gather model calibration data in the summer of 2020. Since a province-wide travel shutdown and social distancing procedures made it difficult to carry out water quality surveying in a small boat, an insufficient amount of fieldwork was conducted to suit the needs of the project. Thus, the project has been put on hold, and the primary researcher has moved to a different project. This document stands as a report on all of the work conducted up to April 2021, intended largely as an instructional document for researchers who may wish to continue the work once fieldwork may freely and safely resume. This research was undertaken at the University of Ottawa, with supporting funding provided by the Earth Observations for Cumulative Effects (EO4CE) Program Work Package 10b: Site Monitoring and Remediation, Canada Centre for Remote Sensing, through the Natural Resources Canada Research Affiliate Program (RAP).
