Description
Nowadays in water resources engineering watershed management plays a vital role. Water harvesting structure based on management of water resources is essential to plan and protect the existing resources. Geographic Information System (GIS) and Remote Sensing (RS) techniques are mostly useful to achieve spatial and non - spatial database that signify the hydrologic features of the watershed use as accurately a s possible. In this study area of Agrani river basin,Upper Krishna basin,Western Maharashtra,India. The yearly rain fall data of 7rain gauge stations (1998 � 2015) together used to calculate the yearly runoff from the watershed using Soil Conservation Service � Curve Number (SCS � CN) method and Arc GIS tool. From the collected annually rainfall data for the years of 1998 to 2015 in the study area annual run off has been calculated. The average rainfall is 46 6.63 mm respectively and typical runoff for the year of 1998 to 2015 is 20.75 mm 3 respectively. The developed rainfall � runoff model is used to understand the watershed and its runoff flow characteristics.
