UPFLOW model was used to provide assessments of capillary rise into root zone soil moisture in shallow water table soils of Obio Akpa river floodplain using drum-culture lysimeters. Soil moisture depletion experiment was undertaken through the use of drums with bases intact and drums with bases removed and sunk in the field at different depths during the dry period with no rainfall and no irrigation. UPFLOW model was validated by comparing simulated capillary soil moisture values from a falling water table with gravimetrically observed data from 0 – 500, 500-1000 and, 1000-1500 mm water table depth in sandy loam and sandy clay soils. Simulated runs mimic the observed fluctuations and trend of capillary rise to the root zone. The statistical pointers of... |
