It captures the risk associated with all aspects of precipitation-induced flooding, including those resulting from tropical cyclone and non-tropical cyclone rainfall, while also accounting for factors that impact rainfall runoff (e.g., groundwater response, surface evapotranspiration, and snowmelt). Officials with the Corps of Engineers feel certain that a dam collapse is extremely unlikely. Hydromechanical elements such as gates and their motors have to be replaced after 30 to 50 years. To put that area in perspective, the entire state of New Jersey is 9 million acres (3.6 million hectares). Probabilistic modeling is essential, and the proprietary modeling methodology simulates over one million individual events, collectively representing 50,000 years of continuous precipitation, runoff, river discharge, and inundation within and across affected regions.
