Integrated Duflow-Drainmod model for planning of water management operation in tidal lowland reclamation areas

The research objective was to develop field operational model control water table level at reclaimed area of tidal lowland for food crop cultivation. DUFLOW computer used evaluate the perfomance management network secondary and tertiary levels, whereas DRAINMOD is soil status block. Results simulation can be improve by passing Secondary Irrigation Chanel (SPD) Drainage (SDU) through channels, gate installation stop-log type weir construction in Channel (SDU). has function as long storage capable or maintain land not quickly drawdown. Drainmod acceptable, this indicated results statistical analysis where correlation coefficient value reaches 0.89. Analysis DUFLOW-DRAINMOD software showed mutually supportive which provide potential information channel supply purpose. This condition an important part because it effect on dynamics targeted block well capacity applied drainage operation system.
