DTM-Based Tile Drain Design and Field Water Management
Why Drainage Planning Needs Accurate Terrain
Water flows downhill. Even subtle elevation differences of 10-20 centimeters determine where water pools and where it drains. LiDAR captures millions of points, revealing terrain features traditional surveying misses.
Key Deliverables for Drainage Design
Digital Terrain Model
Foundation for all drainage analysis. Lidarvisor classifies ground automatically, removing vegetation and crop residue. 0.5m to 1m resolution captures critical micro-topography.
Slope Analysis
Critical for tile drainage design:
• Drain spacing calculations
• Tile sizing (steeper = smaller pipe)
• Outlet placement at lowest points
• Erosion risk identification
Contour Lines
DXF-format contours for drainage design software:
• 10-25cm intervals recommended
• Direct import to design tools
• Elevation attributes preserved
