Models

Model is a broad term encompassing many different aspects of investigating science. In general conceptual models are used to define the general characteristics and components of a physical system and how they interrelate. A mathematical or numerical model takes those concepts, adds the governing equations, and creates a rigorous mathematical framework where the physics of the system must be honored, and hopefully the characteristics of the conceptual model are retained.

Models developed for this study:

• Conceptual model
• Regional water-balance model
• Geologic framework model
• Water-quality model
• Groundwater flow model
• Water-management model

Welcome to the United States Geological Survey (USGS) San Diego Hydrogeology (SDH) project website, which provides geologic and hydrologic information for the transboundary San Diego–Tijuana area, USA and Mexico. This website provides background information about the project; a variety of news items; a large amount of data, in particular for USGS multiple-depth, monitoring-well sites; geologic and hydrologic models; and additional resources including photos, illustrations, and references.
