Hydrology question: A watershed of 21000 sq. km. received total precipitation of 21 in. in 2000. The annual stream flow was reco

Viefleur [7K]

Answer:

combined evapotranspiration is 12.63 in/yr

for avg daily 0.035 in/day

Explanation:

areas = 21000 sq. km

precipitation in year 2000 = 21 in/yr.

stream flow (Q) = 5000 ft³/s

runoff = $\frac{Q}{A}$

runoff= $\dfrac{5000\ ft^3/s}{21000\ km^2}\times (\dfrac{1 km^2}{(3280.84 ft)^2} ) \times \dfrac{86400s}{days} \times \dfrac{365}{years} \times \dfrac{12 in}{ft}$

runoff= 8.37 in/yr

total precipitation = 21 in/yr

hence

Evapotranspiration for watershed

ET= P - R

ET = 21 - 8.37 = 12.63 in/yr

so the combined evapotranspiration is 12.63 in/yr

for avg daily ET= 12.63/365 in/day

= 0.035 in/day
