The flownet at a site of a reservoir is shown in Figure P4.17. (a) How many flow channels are present? (b) How many equipotential drops are present? (c) What is the total head loss? (d) Calculate the head loss between each equipotential line. (e) Calculate the average flow rate if keg = 4 x 10-°cm/s (f) Calculate the porewater pressures at A and B located on opposite sides of the sheet pile retaining wall. (g) What would happen to the wall if the critical hydraulic gradi- ent at the bottom of it (C) is exceeded?
