My query is how to calculate rainfall intensity when you know average annual rainfall.
We are harvesting roof top water as part of a project and further the water will be treated and used for domestic purposes.
As per my calculation I need the intensity of rainfall, but I tried browsing but what I could finally get is the Average Annual Rainfall of
North Goa is around 3000-3250mm.
The soil type is:
Top surface Strata : Brownish Sandy clay.
Underlain Strata : Brownish laterite Gravels
For few soil Texture i could find the permeability factors but not for sandy clay. How can the same be calculated?
Average permeability for different soil textures in cm/hour
Sand 5.0
Sandy loam 2.5
Loam 1.3
Clay loam 0.8
Silty clay 0.25
Clay 0.05
