There are two main drainage channels with different upstreams but flowing downstream into one channel that also functions as irrigation for rice fields outside the Acai sub-watershed. Based on the simulation results in the HEC-RAS software above, it can be explained that using the design discharge at return periods of 2, 5, 10, 25, 50, and 100 years, the drainage channel cannot accommodate the design discharge. The simulated water level exceeds the channel height limit (bank station). There is a difference in water level at each simulated design discharge, the greater the design discharge, the higher the water level in the channel.
