An annual water budget for a critical water-supply basin is needed. During the year, the following data were collected for the 6,200-km2 watershed: precipitation = 740 mm, evaporation and transpiration = 350 mm, average annual streamflow leaving the basin (outflow) = 75.5 m3/sec. groundwater outflow = 0.200 km3, and groundwater inflow (infiltration) = 0.560 km3. Determine the change of storage in the watershed (surface reservoirs) and the change in storage in the drainage basin (surface reservoirs and groundwater together) in km3.
