Analisis Sedimentasi di Tampungan Embung Daerah Irigasi Jurug Lendah Kulon Progo

Jurug irrigation area is one of the agricultural areas in kulon Progo area. The provision of water for the irrigation area is sourced from the dew reservoir located in the upper reaches of the irrigation area. In recent years there has been a shallowing of the reservoir due to sedimentation which resulted in a reduced capacity of the dew reservoir, as well as the closure of irrigation intake doors due to the accumulation of sediment. The analysis used the USLE model to predict sedimentation rates due to land erosion that occurred in the rain catchment area upstream of Jurug dew. Estimating the sedimentation rate in jurug dew aims to prepare the next step as a form of handling the impact of sedimentation that occurs. The results of the analysis showed that the average amount of erosion that occurred in the watershed upstream of Embung D.I. Jurug was 54,66 tons / ha / year and fell into the class of severe erosion hazard level (B III). The amount of sediment over 23 years amounted to 730,12 tons of sediment. Sediment handling can be done by greening, dredging sediments, and building sediments trap.
