. A drainage network of parallel grid system of double side collector, ten laterals are joint to the collector in each side equally spaced. The laterals are concrete pipes with uniform flow and 300 m length where installed at depth of 2m below soil surface with slope of 0.1%, the ground water table was found at depth of 1.2m and the impermeable layer at depth of 6m below soil surface. The hydraulic information indicated that the soil is stable with hydraulic conductivity of 0.8 m/d, the drainage coefficiert is 8 mm/d. What drain spacing must the laterals be applied and what is the inside diameters of the laterals and the collector if we assume a plastic pipe with non-uniform flow for the collector and a slope of 10%.
