How To Calculate Infiltration Capacity

Infiltration capacity is a crucial aspect of hydrology, determining how much water infiltrates into the soil. Accurately calculating it is vital for water resource management, flood control, and environmental conservation.

1. Enter the rainfall intensity in mm/hr.
2. Select the soil type from the dropdown.
3. Enter the land slope in percentage.
4. Click ‘Calculate’ to see the results and a visual representation.

The formula used here is: Infiltration Capacity (mm/hr) = Rainfall Intensity (mm/hr) * Soil Conductivity (mm/hr) * (1 + Land Slope).

Comparison of Infiltration Capacity for Different Soil Types

Soil Type	Soil Conductivity (mm/hr)
Sand	0.1
Loam	0.05
Clay	0.01

• Consider soil moisture content and compaction for more accurate results.
• Regularly update your calculations to account for changes in soil properties.

What factors affect infiltration capacity?

Soil type, soil moisture content, land slope, rainfall intensity, and soil compaction are key factors.
