In this present study, Remote Sensing (RS) and Geographical Information System (GIS) techniques are used to update drainage and surface water bodies to evaluate linear, relief and aerial morphometric parameters and to prioritize the watersheds of the Markandeya River Sub-Basin (MRSB), located in Belgaum district of Karnataka state,India. The Markandeya River Sub-Basin has sub-dendritic to dendr...

We describe two new species of pebblesnails (Lithoglyphidae: Fluminicola) from southwest Oregon based on morphologic and mitochondrial DNA (COI, cytB) evidence. Fluminicola umpquaensissp. n., which had been traditionally identified as F. virens prior to the recent restriction of the latter to the lower Columbia River drainage, lives in lotic habitats in the Umpqua River basin. This species is r...

Streamflows in a Mediterranean mountain basin in the central Spanish Pyrenees were projected under various climate and land use change scenarios. Streamflow series projected for 2021-2050 were used to simulate the management of the Yesa reservoir, which is critical to the downstream supply of irrigation and domestic water. Streamflows were simulated using the Regional Hydro-Ecologic Simulation ...

Oncorhynchusmykiss exhibits a vast array of life histories, which increases its likelihood of persistence by spreading risk of extirpation among different pathways. TheKlamathRiver basin (California–Oregon) provides a particularly interesting backdrop for the study of life history diversity inO. mykiss, in part because the river is slated for a historic and potentially influential dam removal a...

Precipitation extremes play a key role in flooding risks over the Huaihe River Basin, which is important to understand their hydrological impacts. Based on observed daily precipitation and streamflow data from 1958 to 2009, eight precipitation indices and three streamflow indices were calculated for the study of hydrological impacts of precipitation extremes. The results indicate that the wet c...

Geographic Information System (GIS) techniques are being increasingly and effectively used in morphometric analysis and groundwater potentiality mapping of drainage basin owing to its capabilities of manipulation, analysis, flexibility of experimentation and ability to extract topological attributes from various thematic maps, and to work as a unique tool for geospatial modelling. An attempt to...

Decreased streamflow of the Yellow River basin has become the subject of considerable concern in recent years due to the critical importance of the water resources of the Yellow River basin for northern China. This study investigates the changing properties and underlying causes for the decreased streamflow by applying streamflow data for the period 1960 to 2014 to both the Budyko framework and...

The Ganga Plain represents a large proportion of the current foreland 14 basin to the Himalaya. The Himalayan-sourced waters irrigate the Plain via major river 15 networks that support approximately 10% of the global population. However, some of 16 these rivers are also the source of devastating floods. The tendency for some of these 17 rivers to flood is directly linked to their large scale mo...

This paper represents a contribution to the study of hazard caused by the interaction between landslides and river courses. The effects of such interferences are often catastrophic and could include the formation of upstream lakes, potential dam failure, river bed dynamics and morphological alterations. These scenarios could be substantially reduced if it was possible to predict the eventuality...
