The effect of operating variables, like solution pH, sediment dose, contact time and particle size on the adsorption of cadmium ions on bed sediments of the highly polluted Kali river in western Uttar Pradesh has been studied.

Overland flow modeling for urban catchment considering random roughness coefficient and irregular land surface – A research report by National Institute of Hydrology
In this study, a two-dimensional overland flow model has been developed considering random roughness coefficients and irregular land surface for the analysis of surface flow component Posted on 05 Jul, 2010 11:32 PM

In this study, a two-dimensional overland flow model has been developed considering random roughness coefficients and irregular land surface for the analysis of surface flow component. The one-dimensional Richards equation for subsurface flow component has been used for calculating the infiltration from the pervious area.

Procedure for risk based hydrologic design - A research report by National Institute of Hydrology
The report presents the status of risk based hydrologic designs and identifies a computational procedure for developing hydrologic design bases for dams and spillways. Posted on 04 Jul, 2010 10:47 PM

The report presents the status of risk based hydrologic designs that have been reported in literature and based on these, identifies a computational procedure for developing hydrologic design bases for dams and spillways. Some illustrative examples are presented in order to demonstrate the impact of risk based analysis on current design practices.

Flood studies in Satluj basin – A research report by National Institute of Hydrology
The study attempts to do flood inundation and flood plain feature mapping as well as undertake river planform measurements for a part of the river reach of Satluj. Posted on 01 Jul, 2010 01:17 PM

The study attempts to do flood inundation and flood plain feature mapping as well as undertake river planform measurements for a part of the river reach of Satluj. The river is a part of the Indus system and faces flood during monsoon months in spite of various flood control measures that have been adopted. The vast expanse of land adjoining the river course is inundated by large floods.

The report is set in the context of the growing application of computers in the field of hydrology, and the consequent development of large number of softwares for hydrological and allied applications. The report is structured as a Directory and presents brief details about softwares for hydrological and general purpose application available with the National Institute of Hydrology.

Hydrological land use mapping in Narmada basin from Jabalpur to Hoshangabad - A research report by National Institute of Hydrology
The study undertakes hydrological land use mapping in Narmada basin from Jabalpur to Hoshangabad by using various methods for design discharge computations and runoff modelling. Posted on 30 Jun, 2010 11:38 PM

The study undertakes hydrological land use mapping in Narmada basin from Jabalpur to Hoshangabad by using various methods right from empirical formulae to Soil Conservation Services Curve Number (SCS-CN) method for design discharge computations and continuous runoff modeling. The SCS Curve Number method is used to derive an empirical relationship of the catchment hydrological variables and based on this the dimensional unit hydrograph is prepared and continuous runoff modeling done.

Soil erosion and sediment yield modeling using kinematic wave in GIS environment – A research report by National Institute of Hydrology
The study uses GIS techniques for spatial discretization of the Karso catchment into time-area segments to be used in numerical solutions for rainfall-runoff-erosion process. Posted on 30 Jun, 2010 10:37 PM

The study uses GIS techniques for spatial discretization of the Karso catchment into time-area segments to be used in numerical solutions of the governing differential equations for rainfall-runoff-erosion process. Various thematic layers such as soil, land use, slope, flow direction and Digital Elevation Model (DEM) were generated for the catchment using various tools available in GIS. These thematic layers were further utilized to generate attribute information such as Manning’s n, USLE K and C parameters for use in the rainfall-runoff-soil erosion model.

Morphometric analysis of Suddagedda basin - A research report by National Institute of Hydrology
The study, which is a part of the representative basin studies, attempts to do a morphometric analysis of the Suddagedda basin of Andhra Pradesh. Posted on 30 Jun, 2010 08:52 PM

The study, which is a part of the representative basin studies, attempts to do a morphometric analysis of the Suddagedda basin of Andhra Pradesh. The linear, areal and relief aspects pertaining to morphology are studied. In ungauged basins and basins with very little hydrological data, the study of geomorphologic characteristics is important as these can be related with the hydrological characteristics of the basin and thus provide a simple way to understand the hydrologic behavior of various basins.
