Question 5.15 Answer is below in the picture 55% D o AT&T; 22:26 Expert Q&A; Done y 250m, respectively. ,The mean annual groundwater recharge of an aquifer in a watershed is 180mm year. The mean groundwater flow is 105mmyear. If the watershed has an area of 110km ,calculate the aquifer safe yield in m'year. 5.13ln Example 5.20, what would be the pumping rate that would reduce the radius of influence to 200m with a maximum drawdown at the well of 2m. Assume a well radius of 0.6m. 5.14A fully-penetrating well in a confined aquifer pumps at a constant rate of 1000m 3lday for a long time. In two observation wells located 10m and 40m from the well the difference in hydraulic head is0.5m. Ifthe undisturbed head is 200m above the sea level, and the head in the farthest well is 198m (1) estimate the aquifer transmissivity, and (2) calculate the radius of influence of the well 5.15A fully penetrating well in an unconfined aquifer pumps at a constant rate of 2000m3/day for a long time. Two observation wells located 20m and 160m from the well, show a difference in hydraulic head of 2.0m. If the undisturbed head is 250m above the sea level, and the head in the farthest well is 249m, (l) estimate the aquifer hydraulic conductivity, and (2) calculate the radius of influence of the well. in Problem 5.15 the bottom of the aquifer is at the sea level, develop pression to evaluate the aquifer transmissivity as a function of radius. d (2) plot T versus r. Please show answer for 5.15 Answer is: kr 0.025m/day R 3354.97
