Eastern Arkansas, wetland forest, flood control


A mathematical model by Green (1), simulating one-dimensional vertical ground-water movement in unsaturated soils of the prairie region of Kansas, has been adapted for use in a wetlands environment typified by the wetlands forest of Eastern Arkansas. The model consists of two second-order, non-linear, partial differential equations and an algorithm for their numerical solution. The original model was extended to include functions for seasonal changes in transpiration and for drainage of excess precipitation. Before the addition of the two functions, the model reliability was limited to one growth season. With the mathematical model presented in this work it is possible to study interactions between hydrologic changes and the long term vegetative changes. The model potentially is a versatile management tool which could be used to help predict the environmental impact of proposed flood control projects.
