CIVL531 GROUNDWATER ENGINEERING Homework #7 TRANSIENT CASE Question 1: (Unsteady state - unconfined - parameters by Well function) A well, fully penetrating into an unconfined aquifer of saturated thickness 17.8 m, water is pumped out at a rate of 22 lt/s. The drawdowns 's' as measured in an observation well 21 m from the pumped well are as shown below. Determine the aquifers properties 'T' and 'S'. Time 't' (min) 5 20 200 800 1200 1700 2000 Drawdown 's' (cm) 35.1 40.2 46.5 52.5 60.0 71.5 87.8 101.5 120 130.5 141 150 10 50 70 110 400
