This engineering manual provides a general overview of planning and design concepts for groundwater-related projects specific to site investigation procedures, modeling studies, and the interaction between surface water and groundwater.

A basic understanding of the physical & environmental forces that influence the behavior of groundwater is critical in all construction projects. With this understanding, a designer can anticipate important factors that can make a significant impact on a given project. For example, the depth of the water table, at a proposed location, can result in foundation instability issues during and after construction.

The existence of groundwater is well-known and undisputed. Groundwater is the largest source of available water within the United States, accounting for 97% of the available fresh water and 23% of freshwater usage.

In addition to groundwater, the concept of groundwater flow is also important. Groundwater flow is naturally occurring and is one part of the complex dynamic of the earth’s hydrologic cycle. The direction of the groundwater flow is related to many variables such as physical forces, soil conditions, geologic environment, etc. Because of the many variables, a groundwater investigation and modeling study should be implemented for any project involving subsurface construction.

A groundwater investigation requires the acquisition of data. Some methods that are typically employed are the construction & development of wells, surface geophysical methods using nonintrusive gathering of information, and studying the interaction between surface water and groundwater. These methods can be used individually or all together in order to procure the necessary data to evaluate the sub-surface conditions of a site.

Along with groundwater investigations, a modeling study is an important investigative component. A groundwater model is a replica of some real-world groundwater system completed in a controlled environment for information gathering. Models can be as simple as saturated sand packed in a glass container or as complex as three-dimensional mathematical calculations completed via computers.

The topic of groundwater cannot be completely understood without some understanding of the interaction between groundwater and surface water systems. Surface water systems, which include streams, lakes, and reservoirs are in continuous dynamic interaction with groundwater systems and should be included in any site investigation or modeling study.

This course will provide the user with detailed practical information on ground and surface water concepts as they relate to projects involving subsurface construction. With the use of site investigation procedures and modeling studies, an engineer can design a site that will best serve its intended use at any given location.
