Assessment of spatially explicit annual water-balance model for Sutlej River Basin in eastern Himalayas and Tungabhadra River Basin in peninsular India
In this paper, Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) water yield model, based on the Budyko framework which is relatively simple and requires less data, has been applied in Sutlej River Basin, located in the eastern Himalayas and in Tungabhadra River Basin, located in peninsular India. The effect of extrapolation of the lumped Zhang model to distributed model ...

Aqueduct Metadata Document: Mekong River Basin Study
Prior to the creation of the global Aqueduct Water Risk Atlas, indicators were developed and tested in a number of river basins worldwide. The results of the Mekong River Basin Study helped inform and shape the global Aqueduct Water Risk Framework. The Mekong River Basin study contains 14 indicators of water quantity, water variability, water quality, public awareness of water issues, access to ...

Trends in rainfall amount and number of rainy days in river basins of India (1951–2004)
This study aims to determine trends in annual and seasonal rainfall and rainy days over different river basins across India. The data used consists of daily gridded rainfall at 1° × 1° resolution for the period 1951–2004. Sen's non-parametric estimator of slope was used to estimate the magnitude of trend whose statistical significance was assessed by the Mann–Kendall test. Among 22 basins ...

Navigating cooperation beyond the absence of conflict: mapping determinants for the effectiveness of river basin organisations
River basin organisations (RBOs) have made important contributions to the mitigation of waterrelated international collective action problems, decreasing the likelihood of water wars. However, the state of many of the world's rivers remains challenged by environmental degradation and the unilateral exploitation of natural resources. This suggests that RBOs have not been sufficiently effective in ...

Resilience to climate change-induced challenges in the Mekong river basin - the role of the MRC
Climate change and its consequences, ranging from increased water variability to more extreme weather events and from sea level rise to ecosystem changes, introduce new challenges to transboundary watercourses, which already face a variety of collective action problems due to their border-crossing nature. Other changes occurring in river basins, such as changing water-use patterns, development of ...

Integrated river basin project evaluation: a comparative study
Projects carried out in river basin areas often impose changes in spatial functions that are situated in these areas. For decades, project evaluation was carried out by measuring tangible streams of cost and benefits summarised in a cost-benefit analysis. Recently, environmental and social aspects gradually have got more attention in the public decision making process by means of, for example, ...

Dynamic changes of the ecological environment quality in a river basin: a case study of the main stream of Songhua river basin
This paper reports the investigation and analysis of the status and dynamic changes of ecological environment quality in the main stream of Songhua river basin. The evaluation index system was established and the eco-environment quality in the year of 2000 and 2008 was studied in depth. Based on our research, the trend of dynamic changes of the eco-environment quality and its origins have been ...

River basin organization performance indicators: application to the Delaware River basin commission
This paper reports the development of performance indicators of a river basin management organization's ability to undertake integrated water resources management, and applies them to a US basin organization: a river basin commission. Integrated water resources management (IWRM) and integrated river basin management (IRBM) are defined, in the context of international and US advances in IWRM and ...

Mercury concentrations in Pacific lamprey (Entosphenus tridentatus) and sediments in the Columbia River basin
The authors investigated mercury accumulation in Pacific lamprey and sediments in the Columbia River basin. Mercury concentrations in larval lamprey differed significantly among sample locations (P < 0.001) and were correlated with concentrations in sediments (r2 = 0.83), whereas adult concentrations were highly variable (range 0.1–9.5 µg/g) and unrelated to holding time after collection. The ...

How can we involve stakeholders in the development of water scenarios? Narew River Basin case study
This paper present the results of the water scenario development process carried out in the Narew River Basin within the SCENES (Water Scenarios for Europe and Neighbouring States) Project. The overall project objective was to create water scenarios on the Pilot Area level as well as at the Pan-European level. Therefore, in the Narew River Basin, which was one of the Pilot Areas, three scenario ...

Comparative Research on River Basin Management in Korea and Japan
This research aims to explore the mode of River Basin Management (RBM) in Korea and Japan with a comparative perspective. The efforts of implementation of RBM in Korea have included the several attempts to enact the Basic Water Bill, and river basin environmental offices and committees in the four major rivers. Japan has also endeavored to introduce policy efforts to accommodate the new approach ...

Following the proper channels: tributaries in the Mekong legal regime
The Mekong is the archetypal dissevered river basin, separated, divided into parts and broken up by ambiguous and undefined terms in the 1995 Agreement on the Cooperation for the Sustainable Development of the Mekong River Basin. The treaty's text generalizes and redefines the concept of a river basin in which tributaries are marginalized and headwaters are excluded, yet on paper the ...

Long-term variation of water vapor content and precipitation in the Haihe river basin
Based on the Haihe river basin National Centers for Environmental Prediction/National Center for Atmospheric Research reanalysis data from 1948 to 2010 and the precipitation data of 53 hydrological stations during 1957–2010, this study analyzed the variation of water vapor content and precipitation, and investigated the correlation between them using several statistical methods. The ...

Study on river regulation measures of dried-up rivers of Haihe River basin, China
In recent years, the ecological environment of plain rivers within Haihe River basin is questionable because of severe water shortages. Most of the rivers dry up regularly and it is therefore necessary to take measures to improve the river ecological environment. Meanwhile, flood control is the principal function for most of the dried-up rivers, so river regulation works for flood control also ...

Estimation of environmental flow requirements for the river ecosystem in the Haihe River Basin, China
The temporal and spatial environmental flow requirements (EFRs) for the river ecosystem of the Haihe River Basin were analyzed based mainly on the eco-functional regionalization of available water resources. The annual EFRs for the river ecosystem of the Haihe River Basin were 47.71 × 108 m3, which accounted for 18% of the average annual flow (263.9 × 108 m3). The EFRs for ...

River Basin
A river basin is an extent of land where water from rain and melting snow or ice drains downhill into a body of water, such as a river, lake, reservoir, estuary, wetland, sea or ocean. The river basin includes both the streams and rivers that convey the water as well as the land surfaces from which water drains into those channels, and is separated from adjacent basins by a drainage divide. The ...

Vulnerability of freshwater resources in large and medium Nepalese river basins to environmental change
This paper discusses vulnerability of freshwater resources in large and medium Nepalese river basins to environmental change based on evaluation of water resource availability and variation, resource development and use, ecological health and management capacity; and compares the situation with selected sub-basins of the Ganges and the Mekong basins in Asia. Results suggest that water resources ...

Situational analysis of Nairobi River Basin (NRB)
Nairobi River Basin (NRB) remains an important ecosystem owing to its endowment with natural resources and its socio-economic value to Kenyans. However, it is vulnerable due to poor resource management, pollution and an increase in the rising population. Environmental flow is thus necessary to assess and plan on how best to maintain adequate quality and quantity of water resources that people ...
