Details:

The main objective of the study is to find out the Water Surface Elevations and Flooding Condition at the Thermal Power Plant. The flooding area to be inundated around the stream also be identified for the maximum possible flow condition.

  • Review of available information in the form of reports, literature etc. having a bearing on the problem.
  • Digitizing topographical information for the study area. It includes contours and spot elevations, drainage network, village boundaries and roads and railways.
  • Preparation of DEM for the study area for delineation of catchments and delineation of drainage network for comparison with drains of top sheet. Registration of satellite image.
  • Review and analysis of rainfall information to arrive at design storm scenarios of various return periods including SPS/PMP as may be applicable.
  • Compilation of land use soil and other characteristics of the catchments for determining rainfall excess using an appropriate method.
  • Application of event based model for the estimation of flood hydrographs considering historical as well as design rainfall for different return period.
  • Estimation and routing of flood hydrograph through the drainage system of concerned catchments considering appropriate boundary conditions including pre-project scenario as well as proposed scenario.
  • Providing a systematic procedure for evaluating flood inundation boundaries for various expected levels of flood stages under different scenarios.
