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.

Question

2) A rectangular-shaped aquifer in Scrubtown, Texas has been located in a lens of ancient
river gravel buried 200 ft below the surface. The section of the aquifer close to town is 2
miles wide and has a thickness of 30 feet. A well drilled at one end of the aquifer
measured an elevation head of 55 feet and another well, 1200 ft away, measured an
elevation head of 50 feet. Look through your notes to find a reasonable value for the
hydraulic conductivity. Estimate the flow (Q, cfs) and transmissivity (T, ft/day) through
the aquifer. Will this be a good irrigation well (refer to your notes)? The range for Q is
120 – 240 cfs.

Problem 3.5 A well of diameter 0.3 m is constructed to the full depth of an unconfined aquifer of thickness of 150 m. The water table is 10 m below the ground surface. A pumping test of 12 m'/hour has resulted a drawdown of 10 m. Assuming ro = 400 m; calculate the coefficient of permeability of the aquifer. If the flow rate increases to 18 m'/hour, and in the absence of any other data, what will be the best estimate for the drawdown in the well?

Problem 1. Consider a drainage system that consists of horizontal drains located at an elevation ho above the base of an unconfined aquifer of thickness b 10 m (see Figure 1). The recharge rate is r = 100 mm/yr, and the hydraulic conductivity of the aquifer is K = 1 m/d. The design condition of the drainage system is to avoid ponding at the ground surface. You can ignore the vadose zone for this problem. 1. Obtain the relation between the half-distance between drains, L, and the elevation of the drains, ho. Plot this function over the range of feasible lengths. 2. The cost of each individual drain can be split as the cost of the material (fixed) and the cost of installation (which is assumed to be proportional to the depth b – ho). If the fixed cost is $500 and the installation cost is $100 per meter of aquifer length per meter of depth, can you build a drainage system for less than $1 per meter of aquifer length? If so, what depth ho and spacing 2L would you choose? K= 1 m/day 2L = r…
