Growing water demand across the world is increasing the stress on river ecosystems, causing concern for both biodiversity and people. River‐specific environmental flow assessments cannot keep pace with the rate and geographic extent of water development. Society needs methods to assess ecological impacts of flow management at broad scales so that appropriate regional management can be implement...

the determination of temporal and spatial salinity in tidal rivers is significant in supplying water for agriculture purposes, particularly where there is no controller dam at the downstream. in this research, the coherens model was applied to study the hydraulics of water flow, salinity distribution and transmission at the bahmanshir river. coherens is a 3d multi-purpose hydrodynamic model whi...

One of the most important hydrological time series task is to determine if there is any trend in the data and how to achieve stationarity when there is nonstationarity behavior in data. Detecting trend and stationarity in hydrological time series may help us to understand the possible links between hydrological processes and global climate changes. In this study yearly, monthly and daily stream...

This study was initi~.ted to determine the general effects of potential flow reductions in the middle Snake River (Swan Falls Dam downstream to the Idaho-4)regon border) on its riparian vegetation. Considerable water from the river is currently used to irrigate the adjacent Snake River Plain, and increased demand for water in the future is likely. The problem was subdivided into several researc...

The hydrological model WASA (Model of Water Availability in Semi-Arid Environments) has been developed as a deterministic, spatially distributed model, consisting of conceptual, process-based approaches, to quantify water availability in large semi-arid regions. Water availability can be calculated with a daily resolution and on different spatial levels. The model has been applied by Güntner (2...

Investigating the features and flow behavior and related component is one of the complex phenomena that make using of software inevitable. The rivers carry sediment content along with water which is created by erosion of riverbed sediment and erosion caused by rainfall or surface runoff flowing over the catchment area. If the action of river dewatering occurs, the entry of sediment into the int...

The Philippines is one of the most vulnerable countries in the world to the potential impacts of climate change. To fully understand these potential impacts, especially on future hydrological regimes and water resources (2010-2050), 24 river basins located in the major agricultural provinces throughout the Philippines were assessed. Calibrated using existing historical interpolated climate data...
