“…The data for the simulation of the HEC-RAS model are longitudinal and cross-sectional sections of the channel, hydraulic control structure layout, boundary condition (upstream and downstream), hydrological data, and terrain data. Flow simulation due to water level fluctuations should be carried out using unsteady flow analysis [15]. The hydraulic simulation was carried out under four scenarios.…”

Dadahup lowland irrigation area, known in Bahasa as Daerah Irigasi Rawa (DIR) Dadahup, is one of the Ex-PLG areas that has been now included in the food estate program. It has been experiencing low productivity, producing only 1.7 -2.9 ton/ha/year of paddy. Farming on lowland areas is often hindered by inundation during rainy season. Such problems were observed at Blok A5 of DIR Dadahup where inundation might last for a long time. Drainage was hindered since the water level in the channel, being at +1.4 to 1.6 m, was higher than the ground level whose elevations were +1.30 m for the right area and +1.00 m for the left area. Flow simulation by employing HEC-RAS is proposed to obtain a drainage system that can overcome this inundation problem. The use of gates in the secondary and tertiary channels was analyzed to improve drainage performance. The results show that by using gates and pumps can reduce the inundation area and maintain the water level in the channel according to cultivation needs. Such as in tertiary channel, the water level in the right tertiary channel can be maintained at +1.30 m ~ +1.46 m, and that in the left tertiary channel can be maintained at +1.12 m.

“…Another research also conducted a hydraulic simulation using HEC RAS to evaluate the fresh water supply with several water management scenarios for irrigation and acid dilution. The increase of fresh water volume is seen by calculating the incoming fresh water at high tide and low tide to determine the water volume to be discharged or taken out [13].…”

The Unit Tamban is one of the tidal irrigation areas in the Central Kalimantan Mega Rice Project (MRP). The Unit Tamban is an irrigation system consisting of three primary canals with a settling pond or reservoir at each end. After being developed in 1970 by the Tidal Rice Field Development Project (P4S), the three reservoirs no longer function because they are full of sediment. Sedimentation also occurs in primary and secondary canals, impacting tidal attenuation and decreasing canal capacity. The reservoir at the end of the primary canal assists water regulation for irrigation purposes and leaching acid sulfate water. Three scenarios can be used to increase the capacity of the irrigation system, namely reservoir revitalization, secondary canals normalization, and combining two previous scenarios. The performance of both options was assessed by hydraulic simulation modeling using the HEC-RAS software. The hydraulic simulations show that reservoir revitalization can increase the volume of incoming water during high tide by about 90% more than without a reservoir. If the secondary canal normalization is carried out, the fresh water volume entering the secondary canal exceeds 19% before normalization.

“…Each of these data flows must have the appropriate boundary conditions and initial conditions to run the modelling. [5][6] Furthermore, calculations can be done by creating a simulation scenario. In the HEC-RAS software, the condition of the reliable channel water elevation in the influence of its hydraulics and further handling as needed.…”

The handil irrigation system is a traditional water management system developed by local farmers and the government to irrigate rice fields using tidal power for supply and drainage. The canal with a width of 25 meters and a length of about 2 kilometres was developed to irrigate 1,397 ha of irrigated agricultural land in the Palingkau Irrigation Area. At high tide, freshwater enters the canal from the Kapuas Murung River, and drains into the river at low tide. After a long period of development of the area, sediment deposition and changes in channel cross-section occur so that the water system does not function optimally. For the sake of rehabilitation, an analysis was carried out to determine the effective canal length of the canal that is influenced by tidal water, considering channel capacity, tides and land elevation. Hydraulic analysis was performed by using HEC-RAS mathematical modelling. The results showed that tidal fluctuations could not irrigate two handil’s rice fields out of 8 existing handils. Canal rehabilitation in the form of increasing channel capacity is carried out by considering the length of the canal and the irrigation area irrigated, including its effect on improving water quality.
