The Muskingum-Cunge flood routing procedure has been incorporated into the Natural Resources Conservation Service Technical Release 20 (TR-20) hydrologic model. The TR-20 model is an event watershed hydrologic model used to analyze impacts of watershed changes (land use, reservoir construction, channel modification, etc) on volume of runoff and peak discharge. Rainfall runoff modeling is very important in the planning and management of available water resources in a watershed. In this paper, a SCS-based unit hydrograph has been used to simulate the overland flow. Muskingum-Cunge hydrological routing method has been used for channel routing. Hydrologic processes such as infiltration losses and runoff are considered in the present model. Remote sensing and GIS techniques have been used to estimate the spatial variation of the hydrological parameters, which are used as input to the model. The runoff is considered as overland flow and channel flow. In the present work, Madikonda watershed, Warangal district, Andhra Pradesh is the study area. The geographical location of this watershed is in between North latitudes 17° 45′- 18° 00′ and East longitude 79° 15′- 79° 30′. The watershed has an area of 35.9 Sq.Km. The complete watershed has been divided into six sub watersheds. The runoff from subwatersheds has been routed to the watershed outlet through channel network. The developed model is capable for simulating the event based runoff in the watersheds.
