Short Summary

This study developed a novel optimized water distribution model for channel systems, incorporating water transmission time and a rotation irrigation mode, to achieve synchronized water distribution completion and reduce flow adjustment frequency in complex irrigation networks.

Objective

• To develop a novel optimized water distribution model for channel systems that addresses complex many-to-many supply-demand relationships, precisely controls irrigation sequences by incorporating channel water transmission time, and enhances management efficiency through synchronized water distribution completion among rotation groups.

Study Configuration

• Spatial Scale: Lateral channel system of the Bojili Irrigation District.
• Temporal Scale: Irrigation sequences and water distribution completion times within operational cycles.

Methodology and Data

• Models used: Novel optimized water distribution model, improved 0-1 model framework.
• Data sources: Empirical study data from the Bojili Irrigation District (specific data types not detailed in abstract).

Main Results

• The model significantly reduced the time difference in water distribution completion among channels within each rotation group, achieving synchronized completion.
• A substantial decrease in the flow adjustment frequency of branch channels was observed.
• The model effectively resolves water distribution challenges in complex supply-demand networks and provides scientifically sound, operational distribution schemes.

Contributions

• Development of a novel optimized water distribution model that innovatively incorporates channel water transmission time for precise control of irrigation sequences.
• Introduction of a 'rotation irrigation between groups—continuous irrigation within groups' operational mode based on an improved 0-1 model framework.
• Establishment of an optimization goal for synchronized water distribution completion among rotation groups to enhance management efficiency.
• Provision of scientifically sound and operational distribution schemes that offer decision-making support for precision management in irrigation districts.
