ABSTRACT
Hydrological command of waterway system has been altering beneath the crash of mutually environment disparity and human actions in the overall milieu. With the advent of technology it is now possible to model the complete resource allocation of any hydrological network duly integrating both natural and artificial networks. Advance applications allow an excellent automated system to monitor, control and manage water allocations to better utilize water resources, minimize wastage and predict hazards. The first step to all of this is to have accurate information of the catchment areas, so that in coordination with concerned departments, modeling and predictions of futuristic results is possible which will yield better decision making leading to fructifying outcome. Physical hydrologic models for drainage areas are significant utensils to hold water assets management and foresee diverse hydrologic contacts and risks. Indus River is considered as salvation of Pakistan and it is also the largest river of the country. The approximate length of the river is 3180 kilometers and its drainage area exceeds 1165000 km2. Having in view the worth of Indus River and its socio economic implication on Pakistan it was planned to carry out research work on upstream of Terbela from Kachura. The intended approaches of this work were to generate empirical equations based on hydrologic model on a particular reach of the river i.e. from Kachura to Tarbela reservoir and by utilizing Geographic Information Systems and Remote Sensing means. Also the watershed analysis of the upstream of Indus river basin was performed, thus fashioning an essential tool for running and setting up of water resources for state.
