Abstract

The Western North Tarum Irrigation channel plays a crucial role in supplying water to irrigated agricultural areas. However, it encounters challenges in ensuring adequate water delivery to all channel segments. This research assesses water loss during the distribution process in the Western North Tarum Irrigation channel, focusing on the evaluation of channel capacity and the impact of suboptimal water management on water loss. The study employs the HEC-RAS model, a hydraulic system analysis tool, to evaluate the channel’s capacity and simulates its behavior under various discharge conditions. The evaluation reveals that two channel segments, B.TUB 13 and B.TUB 25, have exceeded their capacity limits, resulting in overflow. Sedimentation downstream, particularly in these segments, exacerbates the issue by altering the channel slope and impeding water flow. This research identifies poor water distribution management as a significant factor contributing to water loss in the irrigation channel. Inadequate scheduling and the absence of proper water measurement tools result in instances of overwatering or underwatering in some areas. The lack of monitoring and control in the irrigation system hampers the detection of uncontrolled flow in the channels, leading to substantial water loss and inefficient water use. This research underscores the importance of evaluating and maintaining irrigation channel capacity to prevent overflow and water loss. Furthermore, it emphasizes the significance of effective water management to achieve more efficient water distribution and irrigation. Addressing these challenges is crucial for ensuring the long-term sustainability of irrigated agriculture in the Western North Tarum Irrigation area.Keywords: HEC-RAS, Irrigation Channel, Water Distribution, Water Loss, Western North Tarum

Abstract

Lake Sentarum has a unique role as flood control in the lower reaches of the Kapuas River Basin. Changes in land use and high rainfall can cause an increase in the rate of erosion and sedimentation that occurs in the Sentarum Sub-river basin, which potentially reduces the storage capacity of Lake Sentarum. The objective of this study is to determine the sedimentation rate and analyze the impact of sedimentation on the storage capacity of Lake Sentarum.The erosion rate analysis using the Universal Soil Loss Equation (USLE) method shows that in the 2015 to 2020 period, the most significant erosion rate occurred in 2016,which 2016 was the year with the highest rainfall. The erosion rate that occurred in 2016 in the Sentarum Sub-river basin and Lake Sentarum catchment area was 293,622.79 Ton/Ha/year and 160,413.01 Ton/Ha/year, respectively. The types of land cover that have the most impact on erosion rates are dryland agriculture mixed with shrubs, plantations, shrubs, and open land. The sedimentation rate was calculated using the Sediment Delivery Ratio (SDR) method, where the most significant sedimentation rate occurred in 2016 with the sedimentation rate of the Sentarum Sub-river basin was 201.842,37 Ton/Year which resulted 86.702,05 m3 of sediment volume and the Lake Sentarum catchment sedimentation rate was 117.591,64 Ton/Year which resulted in 50.511,87 m3 of sediment volume. With an average sediment volume in the Lake Sentarum catchment from 2015 to 2020 of 42,668.05 m3, Lake Sentarum will lose its capacity by 0.001% each year.
