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.

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…
