Abstract
Flood is an important phenomenon which often occurs in cities recently. The Case of this paper is the flood in Dr. Junjunan Roadt which is one of high density roads in Bandung and the main road to Cipularang Toll Road. The floods height is up to 40-50cm, and the average of flood duration is abaout 30 minutes. The rainfall used for counting in this research is a return period approximately 25 years with the rainfall value of 80.1 mm. The solutions for reducing the floods is by increasing the drainage capacity as well as increasing the water infiltration to the ground. The reserach method uses the physical experimental model, using the scale mode of 1:30. The experimental results are tested through validation process using Hecr-RAS 5.0.7. Furthermore for the testing model, a scheme of two drainage streams and one river which leads to Citepus river through Box Culvert is used. The results of the testing model indicate that increasing the drainage capacity along the street is the most effective solution in decreasing the potential of floods, while applying the pourous drainage may also reduce the debit of water run off.
