Erosion and Weathering Processes in the Delaware River Basin
Total suspended sediments and the total dissolved solids (TDS) from three river gaging stations, near Delaware Water Gap, Riegelsville and Trenton on the Delaware River measured by the USGS were used to estimate the physical erosion, chemical weathering and total denudation rates of the Delaware River Basin. The denudation rates are 28 and 128 tons/km 2 /yr for the upper stream and downstream s...
متن کاملWeathering in the Subtropical Enoree River Basin, South Carolina, Usa
The effect of watershed spatial scale on chemical weathering is inadequately known for subtropical environments. In order to determine the relationship between watershed scale and weathering chemistry, the Enoree River basin was sampled at seven different spatial scales ranging from second-order watersheds smaller than 2 km^2 to a sixth order watershed of 1840 km^2. The second-order watersheds ...
متن کاملIndustrial waste pollution in the Kano river basin
Kano river basin, which serves as the main source of water supply to metropolitan Kano, is also used as receiving body for industrial wastes from Sharada and Challawa industrial estates. Of the three major rivers in this basin, the Salanta river was found to receive the highest pollution from the industrial discharges with COD of 8,557.4mg/l, total solids of 16,934.6mg/l, hardness of 1,349.6mg/...

15 صفحه اولhydrogeochemistry of thirumanimuttar basin: an indication of weathering and anthropogenic impact
a total of 148 groundwater samples were collected from bore wells from thirumanimuttar sub-basin for two seasons to identify major geochemical process activated to alter groundwater chemistry. the study revealed relationships with the lithology and anthropogenic process. groundwater in the region was dominated by na – ca – mg and cl and hco3 types. the (ca +mg) versus tz+ plot for both seas...
