The use of groundwater flow equations in porous media is often applied optionally, i.e. under saturated soil or only for unsaturated conditions. Tidal agricultural zone of typology C, is an example of how these two assumptions can occur simultaneously. The parameters of the hydraulic conductivity values in this zone can be illustrated by Van Genuhten model approach so that the distribution of water content in spatiotemporal can be described precisely. The numerical model used in land wetting simulation is a finite different method of up to 1D horizontally with an explicit scheme. In the context of the managerial aspects of water management, the scheduling system of tidal-lowland for agricultural purposes, will also be explained from the simulation results. |
