Abstract

Drainage is an artificial channel that functions to channel surface water flow. The ability of drainage to deliver water flow is very influential on infrastructure and socio-community. Drainage that does not match the flow discharge will cause water to overflow to the surrounding area. The current large rainfall conditions certainly have an impact on drainage channels. Monitoring the condition of the drainage channel as a whole is very difficult because it is necessary to manually calculate each dimension of the existing channel. This will certainly take time and money. Current IT developments make this no longer difficult because it can be done digitally using software that is widely developed today. One of the software in hydraulics modeling is HEC RAS 6.3.1. Based on the results of this study, it shows that the conductivity of surface water flow for drainage of building E FT UNILA is no longer able to deliver discharge. This is indicated by the overflow of water at the return period of 2 years, 5 years, and 10 years. The simulation of the research can be seen in chapter four which shows the return time discharge of the various return periods. The maximum discharge capacity of the current drainage conditions is only around 2 m3/second, while for a 2-year return period the maximum discharge is around 4.5 m3/second. Thus, hydraulics engineering is needed to overcome the overflow of water at the difference in discharge.
