For irrigated areas calculate the drain spacing for a falling water table assuming the hydraulic conductivity is 0.4 m/day and the drainable porosit is 0.04. drain depth to center line 1.2 m . initial height of water table 1.2 m .and the height of water table above the center of the drain is 0.8 m. at the midplane after time 1day for the water to drop from the soil surface to 0.4 m below . The depth from the drain to the impervious layer below is 4 m . If you use the first assumption as 24 m , what will be the calculated spacing ? If your solution is not the same as calculated what you will do to get the right spacing
