Calculate additional annual average infiltration due to check dams
Format: Two columns - Precip (mm), PET (mm)
Dimensionless exponent controlling how wetted area expands with stored volume (A = Amax(V/Vmax)β). Values β < 1 indicate strong lateral spreading at low storage (shallow bed with gently sloping sides); β ≈ 1 implies near-linear scaling; β > 1 indicates limited lateral spreading at low storage (shallow bed with steep sides). Typical range: 0.5–2.0.
Ratio of pond evaporation to potential evapotranspiration (typically 0.8-1.2)
Saturated hydraulic conductivity
Wetting front suction head
Change in moisture content
Area of the catchment draining to the check dam
Catchment curve number
