Seepage losses in the Coleambally Irrigation Area – loss estimates from channel automation data

Seepage from open channels is a major source of water loss across all irrigation districts in Australia. Pondage tests are acknowledged as the best direct method for seepage measurement, and the recorded water-level data from automated systems during periods of gate closure can be treated as pondage test data. A computer model that applies pondage test methodology to automated channel control data during periods of shut down in order to estimate...
