Enhancements

The InfoDrainage 2025.4 Update introduces enhanced sub-catchment modelling capabilities through the addition of Land Use and Soil Type polygons. This feature allows the incorporation of detailed polygon attributes to refine hydrological calculations for each sub-catchment, providing a more accurate and spatially informed approach to drainage design.

With this update, land use polygons come with specific attributes that reflect different surface and environmental conditions. Each land use polygon can include:

• Land Use (e.g., Urban Areas)
• Cover Type (e.g., Open Space)
• Condition (e.g., Poor)
• Volumetric Runoff Coefficient (e.g., C = 0.84)
• Percentage of Impervious Area (e.g., 80%)

Soil type polygons, in turn, incorporate Soil Group values as an attribute (e.g., Soil Type A).
