Water is essential element in the living being, at present water scarcity is the major crises in Tamil Nadu state is taking into account that hydrologic time series are limited in Tamil Nadu, there is a strong need for hydrologic modeling tools that can be used to assess the effects of land use on the hydrologic cycle at a watershed scale with the available information. These hydrological models developed at a basin scale are required to improve the water resource management, which is a critical issue in most parts of Tamil Nadu, due to the reason we have selected Nandiar subbasin for our study. The objective of the present study is to evaluate the runoff, one of the output components of the hydrologic balance in the Nandiar sub-basin of Thiruvallur District of Tamil Nadu. An empirical rainfall-runoff model indicates the surface aspects of the catchments, which can be estimated by using Natural Resources Conservation Service - Curve Number (NRCS-CN) is a standout amongst those practically generally utilized strategies. Nandiar sub-watershed basin of Thiruvallur District of Tamil Nadu has been evaluated for the rainfall runoff study and for the estimation of precipitated water.  The runoff and curve number are determined by the rainfall data; land use and land cover data, soil data and respective maps have been generated using ESRI ARCGIS software.
