Modeling

There are many hydrologic modeling approaches available, including conceptual, analytical, empirical, and numerical, each with strengths and weaknesses. Local and regional models already exist in some locations. Therefore, understanding of the capabilities and limitations of existing models and their platforms is key for developing an effective and efficient modeling approach. The selection of the appropriate modeling approach and conceptualization of the model framework (such as the hydrogeologic system, depositional environment, geologic structure, etc.) are critical for successful model application.

Our highly proficient scientists and engineers ensure that the type of model, the model scale, and the complexity of the model framework are commensurate with the objectives of your project.

We develop and apply models from local to groundwater basin scales, including the entirety of the Central Valley of California.
