What may be the average discharge in \( \mathrm{m}^{3} / \) day during a month of 30 days from a dam with a lake area of \( 15 \mathrm{~km}^{2} \). If total precipitation during the month on the reservoir was \( 21.7 \mathrm{~cm} \), total evaporation \( 8.9 \mathrm{~cm} \), seepage loss \( 3.2 \mathrm{~cm} \), average inflow into the reservoir was \( 6.2 \mathrm{~m}^{3} / \mathrm{s} \) and the reservoir water level dropped by \( 87 \mathrm{~cm} \). Answer: Avg. Discharge \( =11.79 \mathrm{~m}^{3} / \mathrm{s} \)

Step 1
First, we need to find the net change in the volume of water in the reservoir during the month. This can be calculated by adding the total precipitation and inflow, and subtracting the evaporation, seepage loss, and the drop in water level. Show more…

A dam released $1000 \mathrm{~m}^{3}$ of water at $10 \mathrm{~m}^{3} / \mathrm{min}$ and then released another $1000 \mathrm{~m}^{3}$ at $20 \mathrm{~m}^{3} / \mathrm{min} .$ What was the average rate at which the water was released? Give reasons for your answer.

A river $21 \mathrm{~m}$ wide and $4.3 \mathrm{~m}$ deep drains a $8500-\mathrm{km}^{2}$ land area in which the average precipitation is $48 \mathrm{~cm} / \mathrm{y}$. Onefourth of this subsequently returns to the atmosphere by evaporation, but the remainder ultimately drains into the river. What is the average speed of the river current?
Writing to Learn A dam released 1000$\mathrm { m } ^ { 3 }$ of water at 10$\mathrm { m } ^ { 3 / \mathrm { min } }$ and then released another 1000$\mathrm { m } ^ { 3 }$ at 20$\mathrm { m } ^ { 3 / \mathrm { min } }$ . What was the average rate at which the water was released? Give reasons for your answer.
