Abstract
The development of swamps for agricultural activities, is one of the efforts to maintain rice self-sufficiency in Indonesia, Kumpeh swamps Irrigation Area in Jambi Province, is, one of the swamps developed for agricultural activities with a potential of around 1,033.6 Ha. The Kumpeh swampy agricultural land development system, uses two primary channels to channel irrigation water or discharge excess water. The main problem in the primary channel of the Kumpeh swamps Irrigation Area is during the rainy season, there is excess water, due to the inclusion of water discharge from the Batanghari River, resulting in inundation between 50 cm to 100 cm, even at some point of the road that is the access of residents to get to the land waterlogged agriculture and plantations. The purpose of this study is to analysis how much excess water is and how to develop drainage management in the Kumpeh swamp irrigation area primary cannal, so that flood events do not occur again. The results of the analysis of average annual rainfall data were obtained at 205.5 mm. Based on the results of the measurement of discharge, obtained the average amount of discharge when it rains, amounting to 39.07 m3/s. With a wet cross section area of the channel covering an area of 29.66 m2, the flood height of 1.44 m. With the height of the embankment from the bottom of the canal was only 1.40 m, the water overflowed and inundated the surrounding area, which caused crop failure. The condition is exacerbated by the overflow of the Batanghari river, and entering through the primary channel or the Kumpeh river, which is the main source of irrigation water. From the analysis results, for handling so that water does not always run off, it is necessary to rehabilitate the width of the channel, in the primary channel from upstream of the intake to downstream (Outlet) secondary channel, from 6 m to 6,5 m, and height the embankment was raised to 1.75 m from the initial height of 1.40 m, as well as the installation of floodgates
