a)A well is pumping from a confined aquafer. If after steady state is reached, the drawdowns at 100m and 200m from the well are 3.6m and 2.4m respectively. Find the transmissivity of the aquifer if Q = 600m3/d ?

b)Maximum annual peak discharges for a stream for a five-years period are : 180, 150, 140, 160, 170 (all in m3/s) find the 20 years max. discharge using Gumble method

A confined aquifer of thickness 35 m is pumped at a rate of 100 L/s from a well of radius 0.5 m. The recorded drawdowns in a monitoring well located 200 m from the pumping well are given in Table. 3.3. Use the steady-state approach to estimate the hydraulic conductivity and transmissivity, if it is assumed that the condition is reached equilibrium after 1-day of constant pumping. time (s) Drawdown (cm) 0 0 10 0.6 100 5 1000 60 10000...
