Abstract

Swampy Irrigation Area (DIR) Technical Implementation Unit (UPT) Dadahup is a swampy irrigation area that needs serious handling of flood control. This flood is resulting in crop failure in several blocks. Furthermore, the malfunctioning of the main gates in controlling the entry and exit of water resulted in a long-standing inundation for the land. This paper presents the hydraulic system of the irrigation network of DIR UPT Dadahup by reviewing secondary data and documentation of field observations. Based on these parameters, the authors simulate the main primary channel using HEC-RAS to perform hydraulic analysis. The flow simulation results show that water entering the land inundated the three canal segments. One has the highest embankment elevation of 1,778 m, with the highest tide on the channel section of 2.25 m. Other results showed that water entering the land also inundated one channel section. The highest embankment elevation was 1,233 m, with the highest tide on the channel section being 1.4 m. From these results, the overflow of water was then eliminated by the heightening of the embankment.
