Sediment Load

The MoEF discussion paper on Himalayan glaciers studies the phenomenon of glaciations and glacier dynamics, a phenomenon that has attained significant attention in recent years, on account of the general belief that global warming and climate change is leading to fast degeneration of glaciers in the Himalayas. It is argued that this would, in the long run, have an adverse effect on the environment, climate and the water.

Integrated Hydrological Data Books are a compendium of important hydrological information of twelve non-classified basins (i.e., other than Ganga and Brahmaputra) consolidated at the national level by the Central Water Commission (CWC).

It covers basic hydrological data on gauge, discharge, silt, sedimentation and water quality collected on a regular basis by the CWC regional field offices, who document it in the form of a Water Year Book, Sediment Year Book and Water Quality Year Book. These along with the relevant land use statistics collected by the Ministry of Agriculture are integrated into this Data Book.Read More

The information is of use to planners, researchers, policy makers and the public at large.

The study estimates geomorphological parameters and soil loss using the Universal Soil Loss Equation (USLE) and Geographical Information Systems (GIS) techniques for the Juni nadi watershed in Jammu Siwaliks with the idea of helping planners develop soil conservation strategies. Geomorphological characteristics of a river basin shape runoff processes and the occurrence of floods especially in the mountainous areas. In ungauged catchments with limited data, such as Juni nadi watershed, these parameters can be useful in understanding the hydrological characteristics. Reliable estimates of soil loss too can be useful in formulating watershed strategies to reduce soil loss to acceptable levels.  Read More
