Short Summary

This study analyzed potential discharge inflow and evaluated the reservoir reliability of the Peniwen Small Dam in Indonesia under various cropping patterns. It found that three optimized cropping patterns achieved reservoir reliability levels ranging from 81.00% to 92.08%, all deemed feasible for irrigation and raw water supply.

Objective

• To analyze the fluctuations in potential discharge inflow using the F.J. Mock method for the Peniwen Small Dam.
• To evaluate the reservoir reliability level through three alternative cropping patterns (Rice - Rice - Secondary Crops) with an initial planting period in December.

Study Configuration

• Spatial Scale: Peniwen Small Dam (Embung) in Peniwen Village, Kromengan District, Malang Regency, Indonesia, with a catchment area of 5.17 km² and an irrigated area ranging from 70 hectares to 150 hectares.
• Temporal Scale: Hydro climatological data from the 2016-2025 period (10 years). Reservoir water balance was simulated on a monthly basis.

Methodology and Data

• Models used:
  • F.J. Mock method for potential discharge inflow analysis.
  • Modified Penman method for calculating reference evapotranspiration (ETo).
  • Monthly reservoir water balance simulation to determine the dam's capacity to fulfill Net Field Requirement (NFR) and intake demand.
• Data sources: Hydro climatological data from the 2016-2025 period.

Main Results

• The average water availability for the 5.17 km² catchment area was 9.08 m³/second.
• The minimum specific discharge observed was 0.006 m³/second per km² (equivalent to 0.06 L/s/ha) in July (2nd period).
• The maximum specific discharge observed was 0.068 m³/second per km² (equivalent to 0.68 L/s/ha) in February (1st period).
• Reservoir operation simulations for three optimization scenarios yielded the following reliability rates, all exceeding the target of 80%:
  • Alternative 1: Uniform crop area of 70 hectares (Cropping Intensity of 210%) achieved the highest reliability of 92.08%.
  • Alternative 2: Crop area increased to 100 hectares (Cropping Intensity of 300%) achieved a reliability of 86.67%.
  • Alternative 3: Maximized crop area ranging from 110 to 150 hectares (Cropping Intensity of 400%) resulted in a reliability of 81.00%.
• All three proposed alternatives were declared feasible and successful.

Contributions

• Provides optimized operational patterns for the Peniwen Small Dam, enhancing its capacity to irrigate agricultural areas and supply raw water.
• Demonstrates the feasibility of increasing irrigated land and cropping intensity while maintaining high reservoir reliability.
• Offers a practical framework for evaluating reservoir performance and water resource management under varying agricultural demands using local hydro-climatological data.
