In a given year, a river basin $($watershed$)$ with an area of $2500$ km$2$ received $130$ cm of precipitation.

The average rate of flow measured in a gage at the river$$s outlet from the watershed was $30$ m$3/$sec$.$

Estimate the water losses due to the combined effects of evaporation, transpiration, and infiltration to

groundwater. How much runoff reached the river for the year, in both m$3$ and cm $($over the watershed

area$).$ Assume storage did not change over the course of the year.
