Dam Breach Studies and Inundation Mapping

Dam Breach Studies and Inundation Mapping

Conducting a dam breach analysis is a critical component of any dam safety program. Knowing the possible effects of a breach allows the Licensee to understand the potential inundation areas and downstream risks. Each dam is unique, whether in terms of its construction, size, or location. In addition, both federal and state regulations affect the process of developing breach models. Kleinschmidt has a highly trained cadre of hydraulic engineers who are well versed in understanding the nature of dams, especially during flood conditions. The breach analyses are primarily completed using an open channel, one-dimensional approach, but when appropriate, two-dimensional modeling is utilized. We have conducted numerous breach analyses for clients throughout the country, using both one-dimensional and two-dimensional models. 

Coupled with the breach analysis is mapping the potentially inundated areas. Kleinschmidt has developed a technique that combines GIS mapping with the breach modeling, thereby providing a consistent platform that unifies both components. Using the latest in GIS mapping also allows maps to be updated as downstream areas change; for example, when housing developments are built. The ability to have this information readily available and in a user friendly map format assists the Licensee, emergency responders, and town officials in developing general town planning (e.g. building restrictions) and Emergency Action Plans.
