Abstract

Ngotok river is a natural channel that act as the waterbody of thirteen river branches and three drainage outlets. The catchment area of Ngotok River is about 722 km2. This river is important for Mojokerto District, since it plays an important role on controlling the yearly flood. Many efforts have been done to solve this flood problems but it remains unsolve satisfactorily yet. Therefore, a research is taken to give one other possibility to overcome the flood effects caused by very high discharge peak at every rainy season. The aim of this research is to distribute the discharge peak by creating some scenarios on releasing the amout of discharge by building pond at any river banch. By these, it can be known the best scenario of distributing the discharge peak based on the time of release and the place of builded pond. It offer 5 scenarios of the amount of ponds i.e. by simulating 2 ponds, 3 ponds, 5 ponds, 6 ponds, 7 ponds at any river banks respectively.. The result of study showed that scenario-3 with 5 ponds is the best scenario to reduce the peak discharge of Ngotok River. This scenario become reduce the peak discharge amount 507.63 m³/s and the depth of water amount 1.460 m
