San Diego Branch Meeting- Groundwater Modeling for Water Managers

The San Diego Branch is pleased to present:

Groundwater Modeling for Water Managers

Lindsay A. Swain, Senior Hydrogeologist


Groundwater models have been used for years in solving groundwater problems. However, too often just how these models work and what value they can provide has not been explained in a way such that everyone can understand their value and possible limitations. This presentation will explain what the model solving program is versus the groundwater basin data set model. The presentation will describe steady state, transient, finite difference, finite element and other terms that have been used to describe groundwater models. The value of using a model with limited data and in prediction will be discussed.


Lindsay Swain is a senior hydrogeologist at Dudek with more than 40 years’ technical and supervisory experience in hydrologic environments from desert to rainforest throughout the United States. His areas of expertise include water resource management and supply, water supply assessments in desert basins, groundwater quality investigations and analysis, groundwater models/development and review, and aquifer storage and recharge. Much of his recent work has been in preparing Water District data for the new California Groundwater Sustainability Law implementation. He has also been involved in evaluating groundwater supplies for shale hydraulic fracturing and proposed power plants in the desert southwest. His technical expertise includes developing one of the first groundwater solute-transport models in the nation for the Upper Coachella Valley. Mr. Swain also participated in the development of the groundwater model for California’s Central Valley, where he developed the program to include water from aquifer compaction and land subsidence into the model. He was also responsible for the first, and so far only, analysis of the chemical quality of groundwater for all the Hawaiian Islands, and has evaluated the carbonate and crystalline aquifers in an 11-state area from New Jersey to Alabama.
