This work presents and applies a new methodology to find the optimal topography of a surface irrigation field, achieving a theoretically uniform surface irrigation. For any variant on surface irrigation (basin, border or furrow, with open or blocked end), the method's result is a particular curved topographical shape of a field. This shape distributes water evenly over the field, so that distribution uniformity is theoretically 100% and deep percolation disappears. The methodology is applied to two theoretical cases: a 1-D blocked-end field and a 2-D square field with corner inflow. For each case, the methodology reaches a particular topography where distribution uniformity is near 100%. To put into practice this methodology, the optimized topography (which has a curved shape) must be approached to a set of slopes. A real example is shown where a real field was laser-levelled with two consecutive slopes to fit the optimized topography, previously calculated with the methodology here presented. The irrigation was evaluated before and after the optimization. The results indicate an increase of distribution uniformity from 82% to 96%.
