Abstract

Situ Gintung disaster that occurred on March 27, 2009 had caused a lot of losses. Thus, flood control as one of  the mitigation  to be important in order to manage flooding in the catchment  upstream  at Situ Gintung. Disaster-prone  areas is Cirendeu Village, and Ciputat Timur. Lack of hydrological information which often leads  to  uncertainty  inflow  in Situ  Gintung  catchment  area,  so the  integration  system  between  real-time hydrological information to be runoff model needs to be developed.Simulation development starts with giving input in real-time rainfall data generated from Automatic Rainfall Recorced at Situ Gintung (x: -6.30023, y: 106.76424). Data was sent by hydrological's  station attendant to server room using Short Message Service (SMS). Furthermore, data that was received will be simulated by system directly to get flood forecasting calculation based on the catchment area of Gintung.The results of these simulations provide time information (t) and peak discharge (Q) inflow flood hydrograph directly  and earlier. Integration  between Automatic  Rainfall Recorced  at Situ Gintung and Rainfall-Runoff model using HEC-HMS  can provide   flood hydrograph  early. So that the peak water discharge  and water level information can be informed earlier and as a tools for the local government for the next flood events prior to take decision earlier. Keywords: Situ Gintung, realtime, Automatic Rainfall Recorced, Rainfall-Runoff model, HEC-HMS.
