English term or phrase:floodplain irrigation
"Most irrigation districts currently use floodplain irrigation, causing water to be wasted." (Source document)
"The Papago and other Sonoran groups perfected a technique called "floodplain irrigation... Here is how it worked: A flash flood comes roaring down the sandy riverbed on a July day. It surges into a temporary catchment basin, where it immediately soaks into the soil or forms a pond for later diversion. Cottonwoods, willows, and burrobushes, some of them artificially planted by the Indians in fencerows along the watercourse, slow the current, spreading the water over a broad, flat surface and trapping the suspended silt for fertilizer. Then, in the mud left by the flood, the Papago plant their seeds, expecting to harvest them before the earth turns bricklike again. The fields irrigated in this way are small, irregular patches -- two acres here, three or four there. This technique, at which they were so skilled, was also called arroyo-mouth, or ak-chin, farming." (Google search http://carbon.cudenver.edu/stc-link/weblink/water/xt/swd.t.h...
