3. The average of total head (H) on a weekly basis at two depths, z1 = -100 cm and z2 = -200 cm below ground surface (z = 0 cm), are presented as follows. Week 2 3 4 5 6 7 8 Hl at z1 (cm) -185 -170 -160 -145 -120 -220 -235 -235 -230 -150 -170 -260 -265 -270 H2 at 22 (cm) The relationship between K and y is given as K (cm/d)=200*2 where y is the average matric suction between two depths. Perform the following tasks. 1 -150 -210 9 -220 -275 10 -250 -280 (1) Compute matric suction (cm), hydraulic conductivity (cm/d), head difference (H2-H1, cm), darcy flux (cm/d), and flow rate (cm/d) per unit surface area (1 m) between two depths for 10 weeks. Use the template worksheet posted in BlackBoard for your convenience. (2) Compute the total volume (cm) of water passing between z1 and z2 vertically through a unit area (1 m) during 10 weeks (if a flow rate is negative, moisture flows toward a negative direction). 1
