Two rivers are 1000 m apart penetrate a confined aquifer 20 m thick. The hydraulic conductivity is x meter per day. The stages of the two rivers are 500 m and 495 m above the sea level, respectively. What is the specific discharge for groundwater in the aquifer? If the reaches of the rivers are 600 m long and there are no pumped wells between them, what is the volume of groundwater outflow/inflow per year from the rivers?
