Flood Control and Water Management

A systematic approach to water management based on Yu the Great's methodology.

Overview

This procedure outlines methods for controlling floods, managing waterways, and reclaiming land through systematic engineering and surveying.

Steps

1. Survey and Assessment

   • Conduct land surveys using measuring tools (准绳, 规矩)
   • Mark boundaries with wooden markers (行山表木)
   • Identify high mountains and major rivers
   • Assess terrain types for appropriate transportation methods

2. Transportation Selection

   • Land travel: use carts (陆行乘车)
   • Water travel: use boats (水行乘船)
   • Mud travel: use sleds (泥行乘橇)
   • Mountain travel: use specialized climbing shoes (山行乘暐)

3. Waterway Development

   • Dredge rivers to create proper channels
   • Build dams and reservoirs (陂九泽)
   • Connect waterways for drainage
   • Create irrigation channels for agriculture

4. Land Reclamation

   • Clear obstructed waterways
   • Drain flooded areas
   • Prepare land for settlement and agriculture
   • Distribute appropriate crops based on soil conditions (e.g., rice for low-lying wet areas)

5. Resource Management

   • Coordinate labor from regional populations
   • Balance food distribution between regions
   • Adjust supplies based on surplus and deficit areas

Expected Outcomes

• Flooded lands become habitable and arable
• Established transportation networks
• Agricultural productivity restored
• Regional coordination achieved

Validation

• Confirm that terrain surveys using 准绳 and 规矩 were completed before waterway development began
• Verify that reclaimed land has been assigned crops appropriate to its soil conditions
• Check that food distribution between surplus and deficit regions is balanced and supply lines are operational
