<b>ABSTRACT:</b><br> <br /> GEOGRAPHIC INFORMATION SYSTEM APPLICATION FOR <br /> THE ANALYSIS OF FLOODS HYDROGRAPH IN URBAN <br /> WATERSHED <br /> By <br /> MAULANA CHATIB DONAL <br /> NIM: 25103004 <br /> <br /> Urban land exploiting without taking into account environment aspects such as the role catchment area will affect to the flow of pattern of surface runoff when the rain happens. The lesser retention area the bigger runoff. Prior to cope with flood problems it should be done an investigation about the volume of runoff compare to the capacity of existing drainage network in other to have a knowledge about the balance between those two matter.</p> It can be done by using hydrological modelling to analyze flood hydrograph by the help of Geographic Information System (GIS) as a tool in expecting such a kind of spatial information related to this problem. The result indicates that the peak of discharge at several oulet are over capacity. <br /> <br /> <br />
