A small tube with a cross-sectional area of 30 cm² is filled with soil and laid horizontally. The open end of the tube is saturated, and after 30 minutes, 150 cm³ of vater have infiltrated into the tube. If the saturated hydraulic conductivity of the soil is 0.3 cm/hr, determine how much infiltration would have taken place in ten minutes if the soil column had initially been placed upright with its surface saturated.

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…
