Project Description

DRI will estimate how groundwater divides evolve in response to variations in river stage, water diversions from the river, and crop rotation. The potential modeling tools can range from simple analytical solutions (e.g., the Dupuit solutions) to generic numerical groundwater flow models. The modeling approach will be selected based on available data and on the developed conceptual models and governing equations. As long as information about river stage and application of irrigation water is available, the model will forecast alterations in the groundwater divide location, and hence the amount of return flows.
