Level-Basin Irrigation

Modeling Microtopography in Basin Irrigation

“…Results of the numerical experiments confirm that microtopography can play an important role in attaining the potential high efficiency associated with level-basin irrigation (Dedrick et al, 1982). The times of advance and, particularly, recession are largely affected by microtopography.…”

Irrigation with Treated Sewage Effluent

“…(Dedrick et al 1982). In this system, the basin is leveled in all directions and much of the infiltration into the soil occurs after the water advance has been completed.…”

On-Farm Irrigation and Drainage Practices

“…To irrigate, a predetermined volume of water is ponded in the basin until infiltration is complete. This requires a high flow rate to be discharged from one or more inlets along one end of the basin (Dedrick et al 1982). This system is capable of applying a relatively small depth of water because of the rapid advance.…”

“…Irrigation streams must be large enough to inundate the basin's surface in a fraction of the time needed for the desired net irrigation depth to infiltrate (Dedrick et al 1982). The irrigation stream must be turned off when the applied volume of water is equal to the design irrigation application.…”
