Status and problems related to mountain hydrology – A research report by National Institute of Hydrology
Posted on 25 Jun, 2010 07:46 PMThe report discusses the status and progress of studies of various hydrological problems associated with mountainous areas experiencing rain and snow. The principal issues related to mountain hydrology on the local and regional scales are discussed and highlighted.
The status of the hydrological studies carried out in the mountainous basins indicates a poor understanding of basic hydrological variables like precipitation, temperature and evaporation. The non-availability of long duration hydrometeorological data for higher altitude areas is responsible for this.

Snow and glacier contribution in the Satluj river at Bhakra dam - A research report by National Institute of Hydrology
Posted on 25 Jun, 2010 12:07 AMThe study estimates the average contribution of snow and glacier melt runoff in the annual flow of Satluj river at Bhakra dam. This study is restricted to the Indian part of Satluj basin. A water balance approach was used to determine the average snow and glacier contribution to the annual flows.
Study of Lake Nainital: Groundwater interaction using Isotope techniques - A research report by National Institute of Hydrology
Posted on 25 Jun, 2010 12:03 AMThe study undertakes hydrological investigations to develop a conceptual model for the water balance of Lake Nainital in Kumaon Himalayas. All the components of lake water balance, except the sub-surface ones, have been measured or estimated using standard methods like isotope mass balance method in conjunction with the conventional water balance method. The sub surface outflow from the lake was assessed by studying the hydraulic interconnection of the lake and downstream springs using environmental tracers.
Simulation of flood hydrograph using an event based rainfall-runoff model - A research report by National Institute of Hydrology
Posted on 25 Jun, 2010 12:00 AMThe study deals with flood estimation through computation of a flood hydrograph for the ungauged Narmada catchment upto Jamtara using the physical and geo-morphological characteristics of the catchment. The catchment area of 17100 sqkm has been sub-divided into five sub-catchments for the purpose of flood estimation.
