Remote Sensing techniques with GIS were used to study the two sub-catchments of the upper catchment of Sukri River, Luni River basin. The measurement and analysis for the two sub-catchments were carried by using GIS for linear, areal and relief aspects. Both sub-catchments have low permeability, high surface run-off, and control of geologic structure. The morphometic analysis and measurements a...

In this study, the stable isotope values of oxygen and hydrogen were used to identify the seasonal contribution ratios of precipitation to groundwater recharge in the Hualien River basin of eastern Taiwan. The differences and correlations of isotopes in various water bodies were examined to evaluate the groundwater recharge sources for the Hualian River basin and the interrelations between grou...

Global climate change is apparent within the Arctic and the south-western deserts of North America, with record drought in the latter reflected within 640,000 km(2) of the Colorado River Basin. To discern the manner by which natural and anthropogenic drivers have compressed Basin-wide fish biodiversity, and to establish a baseline for future climate effects, the Stream Hierarchy Model (SHM) was...

The Amur River is one of the largest rivers of the world. Its length is 4350 km and its total discharge is about 390 km from a river basin of 1,855,000 km. The regime of the Amur River is distinguished by the spring–summer flood, summer low water, summer– fall flood, and winter low water. The spring flood is caused by melting snow and the summer–fall flood is caused by monsoon rains in the rive...

The Piracicaba River basin is considered the most disturbed river basin in the state of São Paulo. Considerable amounts of agricultural residues are seasonally drained into the river, and the region is also highly urbanized and industrialized with an incipient sewage treatment system. The presence of heavy metals has been previously reported for the water and riverbed in Piracicaba river basin....

Holocene sequences in the humid tropical region of Kerala, South-western (SW) India have preserved abundance of organic-rich sediments in the form of peat and its rapid development in a narrow time frame towards Middle Holocene has been found to be significant. The sub-coastal areas and flood plains of the Greater Pamba Basin have provided palaeorecords of peat indicating that the deposits are ...

In the Pacific Northwest, warming climate has resulted in a lengthened growing season, declining snowpack, and earlier timing of spring runoff. This study characterizes the impact of climate change in two basins in Idaho, the Spokane River and the Boise River Basins. We simulated the basin scale hydrology by coupling the downscaled precipitation and temperature outputs from a suite of global cl...
