Daftar Isi:
- The aim of this research is to develop the strategic operation for water management in the tidal lowland agriculture. DRAINMOD computer model was able to use as a tool to evaluate the water status in the tertiary block. Computer simulation of DRAINMOD model has showed good performance which is indicated by the water table fluctuation in the simulation that has the same pattern with the observed value. Statistic analysis showed that the value of Mean of Absolute Error is 0.084,_Root Mean square Error (RMSE) is 2.75 cm,model efficiencies is 1.097 and goodness of fit r2 is 0.92. Therefore the DRAINMOD model was accepted for water table simulation under shallow water soil conditions and it was able to use to develop water management scenarios. The evaluation result showed that the possible water management scenarios in the area studies are rice fallow, rice-corn, corn-corn and rice-conservations. Operational water management in the field consists of water retention,control drainage, and maximum drainage. By using DRAINMOD Model, monthly operation for seasonal water management can be developed.
