Typical Design of Earthen Water Harvesting Structure
I. Technical Data:
a. Hydraulic Data
Catchment Area : 16 ha
Type of Soil : Loam to silt loam
Elevation difference : 8 m
Top of HILL R.L : 109.50 m
Bed level R.L (Deepest) : 101.50 m
Average rainfall : 1300 mm/year
Type of Land : Sloping Forest Land with flatter
valley
Level of Top of Dam : 109.50 m
Full Reservoir Level : 108.00 m
b. Calculation for Peak Discharge
Catchment area (A) : 16 ha
Coefficient of Runoff (C) : 0.35
Intensity of rainfall (I) : 140 mm/hr
Using rational formula
= 360 =0.35 140 16
360 =784360 = 2.19
c. Water Yield
Total Average Rainfall : 1707 mm
Rainfall Received in monsoon period (80%) : 1366 mm
Runoff producing rainfall (60%) : 819.60 Say 820 mm
Runoff coefficient : 0.35
Maximum water yield : 16 x 0.82 x 0.35= 4.59 ha m
