Abstract:
Background: The micro-basins of the Chibunga and Guano rivers are located within the sub-basin of the Chambo River, which starts at the thaw of the Chimborazo, crosses the cities of Guano and Riobamba, and ends in the Chambo River. These rivers are considered fluvial hydrological forces and geological limits of the aquifer, located in this sub-basin. For this reason, our investigation addressed the field capacity in the micro-basins of Chibunga and Guano rivers, to determine the maximum retention potential, i.e., the saturation of water in the soil. Methods: We investigated the change of precipitation to runoff through the correlations between the characteristics of the soil and its vegetation. We applied the Curve Number (CN) method introduced by the United States Soil Conservation Service (USSCS); this represents an empirical model, which relates the vegetation cover to the geological and topographic conditions of the soil. Along with the geographic information system, the model allows to represent the variation of runoffs for each micro-basin, according to the different land use categories, over the time frame from 2010 to 2014. Results: We found that the maximum retention potential is directly affected by CN values, representing the runoff potential. Highest values of 100 belong to the wetlands, urban area, snow, and water, as rain is converted directly into runoff, being impervious areas. The Guano river micro-basin possesses clay soil with CN of 78, the soil texture for eucalyptus forest is clay loam, and its CN value, 46, is the lowest of the data set. Knowledge of field capacity allows to properly evaluate the storage capacity of soil and water conservation. Conclusions: Results of this work will be useful in the quantification of the water balance, to determine the water supply and demand.

Abstract:
River basin management is receiving considerable attention at present. Part of the debate, now occurring worldwide, concerns the nature of the organisations that are required to manage river basins successfully, and whether special-purpose river basin organisations (RBOs) are always necessary and in what circumstance they are likely to (i) add to the management of the water resources and (ii) be successful. The development of river basin management requires a number of important elements to be developed to a point where the river basin can be managed successfully. These include the relevant laws, the public and non-government institutions, the technical capabilities of the people, the understanding and motivation of people, and the technical capacity and systems, including information. A river basin organisation (or RBO) is taken to mean a special-purpose organisation charged with some part of the management of the water resources of a particular river basin. Generally speaking, such organisations are responsible for various functions related to the supply, distribution, protection and allocation of water, and their boundaries follow the watershed of the river in question. However, the same functions can be carried out by various organisations, which are not configured on the geographical boundaries of a river basin. This paper outlines recent work on river basin organisation in Vietnam, and makes some comparisons with the situation in Australia.

Abstract:
This study simulated the inundation process in the Lower Mekong River Basin (LMB). The LMB has suffered from severe floods, especially in 2000 and 2011. To quantify the inundation of water in a basin where large-scale inundation by river water occurs, understanding the conveyance of a river channel during a flood is particularly important. Therefore, we conducted a field survey using an acoustic Doppler current profiler (aDcp) to understand the longitudinal distribution of the width and depth of the river channel and the variation in hydraulic resistance with respect to shear stress on the riverbed. It was found that the width and depth vary longitudinally, and the relationship between them can be estimated by an equation derived from governing equations of water and sediment and the bed load formula. Furthermore, it was revealed that hydraulic resistance decreases with increasing non-dimensional shear stress. Then, the characteristics of the river channel were incorporated into the runoff-inundation simulation. Furthermore, inundation water should be validated not only in terms of inundation extent but also with respect to water depth and velocity. These were estimated using 8-day composite surface reflectance data from the Moderate Resolution Imaging Spectrometer (MODIS) and the SRTM. Simulation results indicated that water level and discharge within the river channel were able to reproduce observed values. Additionally, simulated inundation extent, water velocity, and water depth over the floodplain showed reasonable agreement with the results using the data from the MODIS and the SRTM. Although there are some elements that should be improved, the inundation process in the LMB was simulated appropriately despite its complexity. The method described in this study to set a calculation condition and to validate variables over a floodplain should be useful for runoff-inundation simulation in various large-scale basins.

Abstract The paper summarizes Ukrainian findings and conclusions of the first Ukrainian-Canadian field study on the state of the environment in the Lower Dnipro River Basin. Three major issues were identified during the field study: accelerated eutrophication from municipal and agro-industrial discharges, industrial pollution, and radionucleide contamination of reservoir sediments. The Dnipropetrovsk-Zaporizhzhia-Kryviy Rih triangle has been recognized as an area which has been greatly affected by pollutants originating from many activities, including heavy industry, oil refining, metallurgy, petrochemistry, mining and power generation. The results of biological assays demonstrated that the Lower Dnipro River is endangered by toxic pollution originating from poorly treated or untreated effluent discharges. Of 58 industrial wastewater samples, taken at 31 outlets of the Dnripo and its tributaries, 69% contained various levels of toxic substances. Various degrees of toxicity were detected in 97% of 53 of the wastewater samples, taken at 37 sites. As a result, the majority of the tributaries sampled were of poor water quality and exceeded the statutory pollution standards. The diversity of phyto- and zooplankton was found to be severely reduced as was the native fish population in the Dnipro reservoirs. The maximum Cs-137 concentrations in bottom sediments of the Dnipro reservoirs varied from 31 to 520 Bq/kg, with the highest levels occurring in the reservoir closest to Chernobyl. The Ukranian government has identified the Lower Dnipro Basin as a top priority area for a strategic remedial action plan.

Abstract:
In the permafrost regions, where water filtration zone is limited by the shallow active layer, the surface flow forms a network of hollows, called «water tracks», oriented along the slope gradient. Water tracks are clearly distinguished on satellite images, but poorly defined in the field. The pattern of the water tracks network depends on geomorphological position, permafrost and geological conditions and dominant cryogenic processes. Surface flow could occur in the water tracks during the snowmelt and heavy rains, when the soil is entirely frozen or fully saturated by water. In dry periods, the water tracks form retention zones due to low filtration rates and significant capacity of thawed soil beneath the troughs. Our study of water tracks in the north-western Yakutia showed the changes of their morphology from upstream towards downstream. The water levels in the water tracks have a pronounced diurnal course in reverse phase to the water temperature variation. They are related to diurnal ground thawing dynamics. Hydrology of water tracks depends on the peat thickness, active layer properties and lithology. Water tracks formed by rubble rocks respond to a storm event with rapidly increasing water level. The deeper thawing layer, the smoother water levels rise and decrease.

Abstract:
Abstract Despite the importance of the Missouri River for navigation, recreation, habitat, hydroelectric power, and agriculture, relatively little is known about the basic hydroclimatology of the Missouri River basin (MRB). This is of particular concern given the droughts and floods that have occurred over the past several decades and the potential future exacerbation of these extremes by climate change. Here, observed and modeled hydroclimatic data and estimated natural flow records in the MRB are used to 1) assess the major source regions of MRB flow, 2) describe the climatic controls on streamflow in the upper and lower basins , and 3) investigate trends over the instrumental period. Analyses indicate that 72% of MRB runoff is generated by the headwaters in the upper basin and by the lowest portion of the basin near the mouth. Spring precipitation and temperature and winter precipitation impacted by changes in zonal versus meridional flow from the Pacific Ocean play key roles in surface water supply variability in the upper basin. Lower basin flow is significantly correlated with precipitation in late spring and early summer, indicative of Atlantic-influenced circulation variability affecting the flow of moisture from the Gulf of Mexico. Although increases in precipitation in the lower basin are currently overriding the effects of warming temperatures on total MRB flow, the upper basin’s long-term trend toward decreasing flows, reduction in snow versus rain fraction, and warming spring temperatures suggest that the upper basin may less often provide important flow supplements to the lower basin in the future.

Abstract:
Este trabalho teve como objetivo propor um zoneamento territorial baseado nas características fisiográficas e morfológicas da Bacia do Baixo Rio Chambo (BBRCH), situada na Província de Chimborazo (Equador), como ferramenta para gestão de recursos hídricos. A metodologia utilizada abrangeu as seguintes atividades: estimativa da recarga dos aquíferos locais pelos métodos do balanço hídrico e das estimativas darcinianas; elaboração de modelo conceitual de circulação das águas subterrâneas; coletas de amostras de água em poços e nascentes para análises físico-químicas, químicas e isotópicas; além das estimativas de oferta e demanda e dos possíveis conflitos gerados pelo uso e alocação da água. Os resultados obtidos permitiram identificar a ocorrência de três aquíferos do tipo multicamadas de origem vulcanossedimentar (Llío-Guano, Riobamba e Yaruquíes), compostos por depósitos provenientes de erupções vulcânicas do Chimborazo, Igualata, El Altar e Tungurahua. A recarga desses aquíferos provém, principalmente, das cordilheiras ocidental (Chimborazo e Igualata) e oriental (El Altar e Tungurahua) e, em segundo plano, das precipitações locais. As descargas das águas superficiais e subterrâneas fluem para o rio Chambo, considerado como a área de confluência das drenagens da BBRCH. Os dados hidroquímicos e isotópicos (\'delta\'18O e \'delta\'2H) indicaram a existência de águas de diferentes composições e origens. As águas dos aquíferos Llío-Guano e Riobamba são classificadas como bicarbonatadas cálcio-magnesianas, desde ligeiramente ácidas a neutras, com valores enriquecidos de \'delta\'18O e \'delta\'2H. As águas do Aquífero Yaruquíes e das nascentes em Cubijíes são, respectivamente, bicarbonatadas sódicas a sulfatadas cálcio-magnesianas, com valores mais empobrecidos de \'delta\'18O e \'delta\'2H, indicando que existe influência das atividades vulcânicas do El Altar. A área foi dividida em oito zonas distintas (Z1, Z2, Z3, Z4, Z5, Z6, Z7 e Z8), com características fisiográficas e morfológicas particulares. Este zoneamento servirá como referência para a elaboração do plano de bacia no município de Riobamba e demais províncias equatorianas.
This work aimed to propose a territorial zoning based on the physiographic and morphological characteristics of the Lower Chambo River Basin (LCRB), located at the Province of Chimborazo (Ecuador), as a tool for the water resources management. The methodology used included the following activities: estimation of recharge from the local aquifers using the water balance and Darcinian estimates methods, conceptual model of groundwater circulation, groundwater and springs sampling for physico-chemical, chemical and isotopic analyses, as well as the estimates of supply and demand and the possible conflicts generated by the use and distribution of water. The results allowed to identify the occurrence of three multilayer aquifers of volcanosedimentary origin (Llío-Guano, Riobamba and Yaruquíes), composed of volcanic deposits from eruptions of Chimborazo, Igualata, El Altar and Tungurahua. The recharge of those aquifers comes, mainly, from the western (Chimborazo and Igualata) and eastern (El Altar and Tungurahua) mountain range and, secondarily, comes from the local precipitation. The discharge zone of surface water and groundwater comprises the Chambo River, considered as the confluence area of the drainages located in LCRB. The hydrochemical and isotopic data (\'delta\'18O and \'delta\'2H) indicated the existence of waters with different compositions and origin. The Llío-Guano and Riobamba aquifers are composed of calcium-magnesium bicarbonate waters, from slightly acidic to neutral, with enriched \'delta\'18O and \'delta\'2H values. The Yaruquíes aquifer and the springs located in Cubijíes settlement are constituted, respectively, of sodium bicarbonate to calcium-magnesium sulfate waters with more depleted \'delta\'18O and \'delta\'2H values, indicating influence of the volcanic activities from El Altar. The area was divided into eight distinct zones (Z1, Z2, Z3, Z4, Z5, Z6, Z7, Z8), with particular morphological and water availability characteristics. The zoning will serve as a reference for the elaboration of water resource management plans in the Riobamba municipality and other Ecuadorian provinces.

Abstract:
Doutoramento em Estudos de Desenvolvimento
A gestão de bacias hidrográficas tem uma dimensão inerentemente política uma vez que envolve tomar decisões que são limitadas pelos contextos institucionais, caracterizados por escassez de recursos e conflitos entre múltiplos atores, políticas e estruturas institucionais. No caso de nações em desenvolvimento que padecem de instabilidades políticas, a gestão de bacias hidrográficas torna-se um teatro político em que os principais objetivos de produção alimentar e gestão ambiental ficam fragilizados perante complexos interesses políticos que envolvem o controlo de recursos, a governação de organizações e a política partidária. Enquanto medida de recuperação no pós-guerra e com o apoio das Nações Unidas, a Nigéria adotou uma abordagem integrada para a gestão das bacias hidrográficas. Esta gestão cabe às Autoridades para o Desenvolvimento das Bacias Hidrográficas (ADBH) que estão sob a alçada do governo federal. A sua evolução reflete a instabilidade que caracteriza o federalismo nigeriano. Envolvidas numa política faccionária, com recorrentes intervenções militares e várias reformas no setor da água, as ADBH têm tido um desempenho abaixo do esperado. Este estudo visa explorar a economia política das ADBH na Nigéria, mais concretamente, a trajetória de desenvolvimento das ADBH enquanto reflexo do instável federalismo nigeriano. O documento está organizado em seis capítulos autónomos mas interligados que, no conjunto, encerram uma análise de nível macro e outra de nível micro. O primeiro capítulo descreve a forma como diferentes líderes nigerianos deixaram a sua marca no desenvolvimento das ADBH, desde a sua fundação até à presente administração de Muhammadu Buhari. De uma forma ou de outra, todos os grandiosos planos para aumentar a produção alimentar terminaram em nobres ambições. O capítulo inicia-se com a identificação dos motivos que desencadearam a reorganização da rede hidrográfica na Nigéria. O rescaldo da Guerra Civil, as secas na região do Sahel e a pressão da publicação do relatório das Nações Unidas em 1969 encontram-se entre os principais motivos. Depois de um fraco desempenho inicial em que vários princípios da gestão integrada das bacias hidrográficas foram ignorados, seguiu-se um conjunto de contributos de chefes de estado e presidentes. Infelizmente, nenhuma das promessas feitas surtiu os resultados esperados. O segundo capítulo analisa as ADBH à luz da turbulência que caracterizou o federalismo nigeriano, utilizando o paralelismo como estilo. Este capítulo inicia-se com a discussão do conceito de Federalismo enquanto sistema político e prossegue com a conclusão de que o federalismo existente na Nigéria é peculiar. No início do processo de independência nigeriano, os grupos étnicos não negociaram os termos deste federalismo e a governação militar continuada erodiu os já frágeis pilares criados pelos fundadores da nação. O sistema militar criou os estados e as áreas de governo locais por fragmentação, bem como os mecanismos federais, como são exemplo as três Constituições pós-independência e o Princípio do Carácter Federativo (PCF). O capítulo aborda igualmente vários fatores que influenciaram este paralelismo entre as trajetórias do federalismo nigeriano e das ADBH, nomeadamente, a delicada e volátil questão das minorias, o papel dos militares, o boom petrolífero da década de 70 e o PCF enquanto mecanismo de consociativismo e as recorrentes descontinuidades das políticas públicas e de governação. O paralelismo estabelecido mostra-nos que as ADBH tem uma trajetória que espelha a turbulência do federalismo nigeriano. O terceiro capítulo conclui a primeira parte da tese. Este capítulo foca-se nas reformas introduzidas por diferentes administrações das ADBH e na forma como a organização foi afetada por essas reformas. Os desafios colocados às ADBH começaram com a administração de Shagari, na década de 80, apesar da primeira tentativa para reposicionar as bacias hidrográficas ter ocorrido apenas no final dessa década, com o Programa de Ajustamento Estrutural de Babangida (PAE). Neste capítulo são detalhados o quadro de comercialização parcial criado e alguns dos seus conceitos centrais, as várias fases de preparação das ADBH para o seu novo estatuto, o seu processo de recapitalização e o cronograma da organização até se tornar financeiramente autossuficiente. Todo este processo foi condicionado pela cedência de Babangida à pressão pública e sua consequente demissão. Depois desta tentativa de comercialização das ADBH, várias outras se seguiram mas nenhuma foi bem-sucedida. No capítulo quatro inicia-se a segunda parte da tese, que corresponde a uma abordagem de nível micro à Autoridade para o Desenvolvimento da Bacia Hidrográfica do rio Lower Benue (ADBHLB), uma das doze autoridades existentes no país. Foi dado enfoque a como é que as dinâmicas observadas na primeira parte da tese ocorrem no contexto de apenas uma Autoridade. Este quarto capítulo documenta as observações conseguidas em projetos de irrigação da ADBHLB. As evidencias apresentadas provêm de dezasseis instalações da organização, incluindo a sua sede. Na conclusão do capítulo, são discutidos os traços característicos dos projetos de irrigação. Todos os projetos tem recursos naturais abundantes tais como vastos terrenos, acesso a água e localização em planícies férteis. No entanto, são disfuncionais e tornaram-se dívida pública. A constante mudança política deixou uma longa cadeia de construções inacabadas (e.g. a barragem inacabada de Guma, os terrenos abandonados em Tede ou sistemas de irrigação inacabados em Doma e Guma) e gestores de projeto desesperados. O capítulo cinco trata os impactos da fragmentação do federalismo ao nível de análise micro e detalha como é que o conflito de interesses se transformou à medida que o numero de partes interessadas na ADBHLB aumentou. Este capítulo dá-nos a conhecer como é que a ADBHLB reflete a instabilidade do federalismo nigeriano através de ilustrações da fragmentação estrutural da bacia hidrográfica da ADBHLB, que passou de dois estados fundadores (Benue e Plateau) para quatro (Benue, Plateau, Kogi e Nasarawa), após a fragmentação dos estados fundadores. O capítulo apresenta igualmente casos em que a ADBHLB se tornou uma plataforma política na medida em que os seus executivos de topo utilizam as instalações governamentais para alcançar os seus objetivos políticos. Neste capítulo, é possível concluir que os reveses descritos são um efeito em cascata da fraca negociação do federalismo na Nigéria. O sexto e último capítulo da tese dedica-se a como a ADBHLB respondeu à política de comercialização parcial de Babangida, o esforço renovado de Obasanjo e administrações seguintes. O capítulo inicia-se com a análise do quadro para a comercialização criado pelo governo federal e o plano articulado pela ADBHLB como resposta. O plano estratégico da organização traçou a forma como a ADBHLB se deveria impor no mercado competitivo mas não foi feita qualquer implementação. O capítulo finaliza com a conclusão de que o plano estratégico da ADBHLB foi mal sucedido, com base numa análise aprofundada dos relatórios do trabalho de campo realizado. Esta investigação foi afetada pela limitação do acesso a documentação oficial, tanto ao nível federal como ao nível da ADBHLB. Além disso, a falta de segurança vivida no país não permitiu a cobertura de todas as instalações da ADBHLB. Contudo, o estudo mostra claramente que o fraco desempenho das ADBH reflete a instabilidade do federalismo fragmentado nigeriano. A busca pela revitalização, reposição e comercialização parcial das ADBH deve ter em consideração as suas motivações. O documento termina com um conjunto de sugestões de pesquisa futura. Entre elas, inclui-se uma análise das políticas que estão a conduzir ao crescimento do número de ADBH e, em particular, ao argumento de que não há correlação entre a dimensão das ADBH e a dotação orçamental recebida do governo federal.
The management of river basin organisations is inherently political, due to its unalienable constraints and institutional structures. Characterised by resources limitedness, conflicts of multiple actors, policies, and evolving institutional structures, river basin organisation often becomes the centre of political intrigue and power-play. In developing nations struggling with political instabilities, river basin management is the theatre of complicated politics, and its yield is often minimal since the primary goal of agriculture becomes emasculated by other interests. This study explores the political economy of the River Basin Development Authorities (RBDAs) as a mirror phenomenon of Nigeria’s peculiar and challenge-laden federalism. The mission of the RBDAs become an instrument in the politics of fissiparous fragmentations, recurrent military interventions, and a series of reforms in the water sector. In six separate but interrelated chapters, set out as macro-level and micro-level analyses, this study explores the development trajectory of the RBDAs as a reflection of the turmoil that characterises Nigerian federalism. The macro-analyses focus on the federal actors, while the micro-analyses examine the case of the Lower Benue River Basin Development Authority (LBRBDA). The literature review and the field trips confirm, at both levels of analysis, the claim that river basin organisation is intrinsically political. The study also found that the social life or the politics of the RBDAs derive its push from the general politics of its ambient environment, and bears a likeness to it, as exemplified by the case study. The quest to reposition Nigeria’s ailing RBDAs must further explore the role that politics plays in the creation and management of the RBDAs. The insights from the study will prove valuable to the stakeholders and policymakers. Considering the findings and limitations, the conclusion also highlights some areas for further research.

Abstract:
Water issues in the Lower San Pedro River basin in southeastern Arizona are becoming increasingly contentious as urban development, agriculture, and mining needs compete with the needs of the riparian habitat. To better understand the water demands in this basin, a new groundwater flow model has been created. First, the conceptual model was produced using various Geographic Information System (GIS) applications. A new method allocating digital precipitation data to the smaller drainages within the watershed was used to estimate mountain front recharge. Well data was gathered from both the United States Geological Survey (USGS) and Arizona Department of Water Resources (ADWR). Depth to bedrock was interpolated from an earlier gravity survey of the area. The current extent of riparian vegetation was determined by recent United States Forest Service aerial photography. GIS shapefiles were created depicting the data necessary for MODFLOW. Second, the numerical MODFLOW model was formed using GMS (Groundwater Modeling System), a graphical user interface for MODFLOW. GMS was used to create the grid, allocate the information from the shapefiles into MODFLOW input files, create the MODFLOW numerical model, and calibrate the model. The model results project potential impacts to the overall sustainability of groundwater within the basin. In the future, the model will be used as an administrative tool to assess alternative land management scenarios and their abilities to sustain or improve the riparian habitat along the San Pedro River.

Abstract:
The purpose of this study was to examine the characteristics of riparian plant communities along a succession gradient of livestock exclusion in the Lower Columbia River Basin (LCRB). Livestock exclusion is an example of a passive restoration practice throughout the region. However, few studies have focused on the effects of livestock or livestock exclusion on riparian wetland ecosystems in this area. Two passive restoration sites, 3 and 13 years since livestock exclusion, and a control site with a continued livestock grazing presence were examined. It was hypothesized that native plant species richness would be lower in the excluded wetlands than in the grazed wetland due to the competitive exclusion from an increase in non-native plant dominance in the absence of grazing. Data were collected along six (45-60m) randomly distributed transects which were aligned perpendicular to the wetland shoreline of each site, providing a total of 18 transects with an accumulative length of approximately 990 meters. Vegetation cover data were collected for 10 cm intervals along these transects using the line intercept method during low water periods in August and September of 2009. The Kruskal-Wallis one-way nonparametric analysis of variance by ranks and the Mann-Whitney U test were used to detect significant (p

The broad theoretical concern of the thesis is to examine an ambivalent dimension in the formation of social identities in which similarities in attributes and symbolic representations can become the source of conflict when they appear to have been appropriated and alienated. In studies of the role of ethnicity in the creation and reinforcement of social identity there is very often the assumption that social cohesion arises from similarity and that actual or perceived differences lead people to identify one another as members of opposing ethnic groups. I have suggested, however, that differentiation arises from the claims that are made to this distinctiveness, and that disputes over cultural commonalities or shared ethnic symbolism actually serve to sustain ethnic boundaries in situations where powerful external forces are at work in promoting integration. I have used Tambiah's theoretical model for the investigation of ethnic identity to structure a series of case studies drawn from a community study of Pella, a communal area with a Roman Catholic mission station, and studies of other former Coloured and Nama Reserves associated with Christian missions in the Lower Orange River Basin of Namaqualand. A distinctive historical feature of this region is a general trend towards social integration as opposed to the separation found in other parts of southern Africa. In the case studies that make up the body of the thesis I have presented the sociality of the community at Pella from three perspectives, socio- political, religious and material cultural, to show the complex ways in which ethnicity has operated over time in the formation of social identities. Setting the colonial and post-colonial encounters in Gramsci's notion of hegemony as involving asymmetrical class relations and cultural imperialism, I argue that the ongoing role of the universalist Christian churches in shaping patterns of identity has to be understood in terms of their commitment to what has come to be called "inculturation" as a way of indigenizing their versions of Christianity in Africa and throughout the world. In addressing the questions of coercion and resistance, hegemony and accommodation, localization and revitalization, and the role of missions in identity politics, I contend that the concept of "inculturation" is vital to an understanding of oppositional responses to globalization, as these are expressed in cultural and ethnic terms at local level through a politics of similarity as a form of everyday resistance to the coercive and hegemonic forces of globalization. The thesis is thus a contribution to a wider debate in anthropology on role of ethnicity in cultural transformation and continuity in the context of the gathering crisis of the nation-state and the ongoing revolutionary reconstruction of the contemporary world order.

Abstract:
The Bridge River drains the east slope of the Coast Mountain Range and is a major tributary of the Fraser River in southwestern British Columbia. The lower Bridge River has been regulated since the installation of Terzaghi Dam in 1948, which left a section of dry riverbed for an interval of 52 years prior to 2000. An out-of-court settlement between BC Hydro and Federal and Provincial Fisheries regulatory agencies resulted in the required experimental discharge of 3 m3/s below Terzaghi Dam in 2000. This study investigated growth of black cottonwood (Populus trichocarpa) trees in response to the experimental discharges. Mature trees did not show a significant response in radial trunk growth or branch elongation. In contrast, the juvenile trees displayed an increased growth response, and the successful establishment of saplings provided a dramatic response to the new flow regime. Thus, I conclude that cottonwoods have benefited from the experimental flow regime of the lower Bridge River.

Abstract:
Studiul a fost realizat pentru prezentarea oportunităților de dezvoltarea durabilă în RRI prin aplicarea prevederilor Directivelor de mediu ale UE, și atingerea stării bune a ecosistemelor acvatice care au fost deteriorate în perioada sovietică prin folosirea intensivă a agrochimicatelor, utilizarea irațională a resurselor de apă, deversărilor necontrolate a apelor uzate. În această perioadă nu existau oportunitățile privind cooperarea internațională și atragerea celor mai bune practici de management al mediului. Actualmente cooperarea cu UE se desfășoară în baza realizării prevederilor directivelor respective. Articolul prezintă primele rezultate obținute în cadru consultării cu APL, lecțiile învățate privind cooperarea cu UE la nivel local.
