Abstract: Water is unquestionably the foremost vital resource. Use of water and its management is one among the main challenges for humanity. The demand for water is endlessly increasing thanks to growth, the intensive urbanization and also the development of business and agricultural activities. Within the direction of accelerating pressure on this important resource, it’s needed to line up the ample instruments to make sure a rational and well-organized management of this resource. During this context, the hydrological modelling is basically used as an instrument to access these resources. The objective of this paper is to simulate runoff using HEC-HMS hydrological model and SCS-CN method in Brahmani-Baitarni basin. The mappings were prepared by using SRTM-DEM of 90m resolution map, soil map, and land use/land cover map. In this paper, water balance part runoffs are computed and its result is calibrated and validated and eventually, the performance of the model is evaluated.
