Introduction

The objective of this example is to illustrate how SEEP/W can be used to simulate the filling and draining of a pond. The pond is near a hypothetical river that is undergoing seasonal changes in river water level height. The water from the rising river is allowed to pass through the soil and into the pond, causing the water level to rise, or vice versa. As the head in the pond is not known, and depends on the volume of water seeping out of or into the soil, a special type of boundary condition, called the Water Total Head vs. Volume boundary condition, is used. Two methods of using this boundary condition are introduced, with emphasis on the new automatic boundary condition functionality.
