The report deals with hydrological soil classification in Sher-Umar river doab in Narmada basin. The study and classification of soil has in the past been undertaken by engineers and agriculturists who have confined themselves to those soil properties and materials in which they had a special interest. The soils have also been studied by geologists, but the geological description of an area does not include the information required by soil scientists. The classification designed by soil users have tended to be of limited value to others as they were designed to serve a specific and limited purpose.

The report presents a seasonal rainfall-runoff model developed for the Saurashtra region as well as parts of Narmada river basin. The successful planning and implementation of water resources projects require reliable data on volumetric runoff. It is not feasible to have discharge stations in all the river basins of interest given resource constraints. Therefore, regional rainfall-runoff models are preferred. The utility of such models can be improved if rainfall-runoff models for different regions are developed using data specific to the regions.

The study attempts to determine the useful life of the Bargi reservoir and assesses the sedimentation rate in it using satellite data. Periodical surveys are essential to provide a correct understanding of the sedimentation process going on in a reservoir, so that remedial measures can be undertaken well in advance and reservoir operation schedule planned for optimum utilization of water.

The report presents a study on the Sagar lake wherein the various water balance components like inputs and outputs have been quantified to visualize the influence of these parameters on the storage changes. Lakes play an important role in shaping the hydrological, ecological and environmental balance of the region by developing the flora, fauna and habitation of the aquatic biota. Like other lakes, Sagar lake too faces manifold problems of siltation and deterioration of water quality, thus threatening its survival.

The report attempts to compile all the published works on the Sagar lake in one place. This includes brief description of the historical and the geographical background of the lake, details of water quality analysis carried out in various years, present position of the lake and various schemes proposed and implemented for the improvement of the condition of the lake. 

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.

The study develops a regional hydrological model for estimating flow characteristics at ungauged sites of Narmada basin using climatological, hydrological and morphological variables. The term low flow is broadly used to describe stream flows that are significantly below average or below normal flow levels.

The study carries out sediment yield estimation for the Shakkar catchment of the Narmada river in Madhya Pradesh and successfully implements a methodology for prioritization using Geographical Information Systems (GIS) and image processing on ERDAS and ILWIS software.

The study deals with the estimation of hydrological soil parameters of the doab between Sher, Umar river and Bargi left bank canal in Narsinghpur district of Madhya Pradesh. The soil properties determined are soil texture, soil moisture characteristic curves and saturated hydraulic conductivity.

In this study, a spatially distributed unit hydrograph was developed for the Kolar basin in Madhya Pradesh using Arc Info GIS package. The one-hour distributed hydrograph was determined for the basin using S hydrograph technique from the time-area diagram of the basin.
