Question: The average annual precipitation ( P ) for central New Hampshire is 1 0 7 cm / year . On average, 1 / 4 of

The average annual precipitation (P ) for central New Hampshire is 107 cm/year. On average, 1/4 of this annual rainfall recharges the groundwater (G ), with the remainder available for overland runoff ( R) and evapotranspiration (E ). Average annual streamflow is (Q ) is 0.1 cubic meter per second. Streamflow is made up of two components: baseflow ( B), the groundwater discharge, and overland runoff (R ). Average Annual baseflow (B ) is generally assumed to be equal to average annual groundwater recharge. Based on this information, (a) Draw a picture showing the water budget for this watershed and (b) Using a watershed area of 4.5 Km2, calculate the total volume of water (in cubic meters) which is lost to evapotranspiration (on average) each year? Show the yearly volume of water (in m3) for each component of the water budget in a box for the water budget developed in (a). Assume that the groundwater and surface water boundaries coincide.
