LID Prototype of Runoff Management Model in Sub-Catchment Area for Urban Water Sustainability: Case Study of Tegal City

EasyChair Preprint 6428

Abstract

In the city of Tegal, the tributaries are in critical condition as indicated by several indicators, including an average flow velocity of 0.002 mm/second, an average depth of 1.2 cm, heavy pollution, 2 - 3 average width, and there is no vegetation at all. It is necessary to develop a hydrological model for controlling runoff using a low-impact development module. It is necessary to develop a hydrological model for controlling runoff using a low-impact development module to cope with flooding and to increase the rate of water infiltration through permeable structures. Hydrological data at six observation points in the Gung sub-watershed and other supporting data such as rainfall intensity were used to design a prototype model based on LID parameters. The prototype of the designed model was validated using the PEST technique on the components and elements of the model. The research resulted in a prototype runoff water control management (RMM) model which includes: 1 permeable structure, 1 river vegetation area, 1 infiltration trench.
