Surge-ring Infiltrometer and its Application to Simulate Infiltration
Abstract Cumulative infiltration into thesoil profile during constant on-off cycletimes of surge irrigation was estimatedusing surge-ring infiltrometer data. TheKostiakov equation was employed to modelthe cumulative infiltration behaviour andits reduction into the soil duringdifferent surges. The two-point techniquewas applied to determine the unknownparameters of the Kostiakov equation. Itwas concluded that the surging phenomenasubstantially reduced water movement andthe reduction in cumulative infiltrationvaries from 60 to 83% during first surgeand 60 to 27% for the subsequent surges. Asurge infiltration model was also developedby introducing a `surge factor' into theKostiakov equation to generate infiltrationdata for subsequent surges, using the firstsurge / continuous infiltration data.Results of the study revealed that theinfiltration data of the surge-ringinfiltrometer and that generated by surgeinfiltration model matched closely.
