Concept explainers

Groundwater Flow

The term groundwater refers to the water which is found beneath the earth's surface. Pores present in the soil and rocks with fractures make a passage for rainwater to enter the earth's surface and deposit as groundwater. The flow nature and direction of groundwater under the earth's surface directly impacts the strength and compressibility of the soil, which reflects its ability to support structural loads.

A confined aquifer shown has hydraulic conductivity of 52 m/day with void ratio of 0.282. The average thickness is 30 m and the average width is 4 km. el = 85 m el = 55 m 80 m aqulfer 1400 m Determine the nearest value of the tirne of travel from the head of aquifer to a point 5.2 km downstream in days (in a whole day).
In a groundwater field test, a tracer took 8 hours to travel between two observation wells which are 56 m apart. The difference in water table elevations in these wells was 0.70m. The volume of the void of the aquifer is 30% of the total volume of the aquifer. What is the hydraulic conductivity of the aquifer, if the dynamic viscosity of water is 0.995x10-³Ns/m³?
