Peatlands have a unique hydrological system so that water management based on the peatland water system is a must. Peatland management by building drainage will cause changes in the structure of the peat, causing a high risk of forest fires, especially during the dry season. In this paper, we propose a model of tropical peatland drainage based on the 2D Darcy equation. With the initial and boundary conditions that we provide, the solution is solved using the expansion of the eigen-function. The simulation results show that the dynamics of the peat drainage water table is strongly influenced by rainfall rather than water input from the canal. There is a time lag between the rainfall and the increasing of the water table with the hydraulic coefficient determine the length of the time lag.
