A system of pipe drains of (0.2m in diameter) are used to drainage area, the drains are located (1.8m) below ground surface. The impervious layer about 6.8m from ground surface, k=1.0 m/day. The successive irrigations are every 20 days, deep percolation losses toward water table (W.T) are 40mm/irrigation. Determine the spacing between drains. (1) To maintain W.T level of 0.8m. (2) To maintain W.T level of 1.2m.

Exercise (51 A system of pipe drains of (0.2m in diameter) are used to drainage area, the drains are located (1.8m) below ground surface. The impervious layer about 6.8m from ground surface, k = 1.0 m / day. The successive irrigations are every 20 days, deep percolation losses toward water table (WT) are 40mm / irrigation. Determine the spacing between drains (1) To maintain WT level of 0.8m. 2) To maintain WT level

2. Discuss the factors affecting the infiltration capacity of an area.
600m³/day of water is to obtained from a proposed infiltration gallery, which is placed at 6m depth from sub-surface water table. The coefficient of permeability of the soil aquifer is 100m/day. Find the length of the gallery if the drawdown in the gallery on pumping is not to exceed 4m. the radius of influence may be assumed to be 100m.
3) The actual infiltration rate is less than the infiltration capacity. * True False
A masonry dam has a coefficient of permeability of 5m/day. a. Determine the seepage flow (m3/hr) Please answer this asap. For upvote. Thank you very much
Ex 12-6: agricultural land subjected to heavy rainfall of 10 days duration which caused groundwater recharge of 3mm/day. This water was drained by perforated pipes 20cm diameter laid at 2m depth below soil surface. If the depth of impervious layer 8m .find the spacing of drains to maintain the permissible groundwater table 1.5 m below soil surface. The hydraulic conductivity 0.5 m/day. Use any available equations (Hooghoudt Kirkham and Dagan)
Design a composite pipe drain of parallel grid system to be installed, the lateral is joints the collector from both sides. The laterals are of 300 m length on one side and 200 m on the other side and will installed at depth of 2 m below soil surface with slope of 0.05%. The ground water table was found at depth 1.5 m and the impermeable layer at depth 5 m below soil surface. The hydraulic conductivity is 0.75m/day. If the amount of irrigation water that must be drained 20% of the irrigated water and the infiltration water which escape is 11% of irrigated water the area must be irrigated by 30 cm per 3 days. The collector diameter is 50 cm with slope of 1%, and the number of laterals in one side is 1
