â â â  in the last years, have been accelerated increased the damages of landslides by natural and anthropogenic factors. one of the main solutions to decrease landslide hazards is avoid from prone areas. for this purpose, it is necessary to prepare the landslide susceptibility map. in this research, after field studies in the ilam dam basin, nine factors including slope gradient, aspect, eleva...

The study area is located in the Eastern Anatolian Plateau found Alpine-Himalayan fold mountain belt. Engil River Upper Basin (Güzelsu) within Lake Van Closed Basin, largest soda lake this belt terms of volume and area. This aims to investigate geomorphologic evolution Güzelsu support development with morphometric analysis. With aim, a Digital Elevation Model (DEM) was created aim quantifying e...

We determined the role of the hyporheic zone (the subsurface zone where stream water and shallow groundwater mix) in enhancing microbially mediated oxidation of dissolved manganese (to form manganese precipitates) in a drainage basin contaminated by copper mining. The fate of manganese is of overall importance to water quality in Pinal Creek Basin, Arizona, because manganese reactions affect th...

A 6-year study of mussel communities and their • habitat in the Neversink River basin in southeastern New York found that the principal factors apparently affecting mussel-species richness were site (reach) elevation, drainage-area size, channel width, bottommaterial composition, water velocity, shear stress at bankfull discharge, and water quality (acidneutralizing capacity (ANC) and concentra...

A bedload trap in the riverbed provided direct quantitative measurement of debris-transport rate in the East Fork River, Wyoming, a basin of 466 km(2) drainage area. Traction load moves only during the spring snow melt season. Data collected in three spring runoff seasons during which a peak flow of 45 m(3)/s occurred showed that transport rate is correlated with power expenditure of the flowin...

Morphometric analysis is mathematical evaluation and measurement of the earth’s shape, surface its landform’s dimension. Dhund river basin in Jaipur district Rajasthan India has been carried out to evaluate various morphometric parameters following linear, areal relief aspects. The drainage basin, which covers a total area about 1828 km2 lies eastern part with maximum minimum elevation 603 m 21...

This report reflects the number and boundary delineations of earlier work done by the Minnesota River Assessment Project (MRAP), in which the Minnesota River Basin was divided into thirteen major watersheds. The majority of these watersheds contain the drainage area of only one of the Minnesota River's major tributaries, while the others contain a given reach of the Minnesota River as well as t...
