Service Description: The Automated Geographc Resource Center (now AGRC) in conjuction with the Utah Division of Wter Rights, created a dam inundation feature class containg Cross Sections and potential flood areas.
Cross sections are used to model and predict how water would flow if a dam were to fail, providing crucial data for flood risk assessment, emergency planning, and infrastructure design.
Layout: Cross sections are typically taken perpendicular to the anticipated flow of water both in the channel and across the floodplain, capturing the entire extent of potential flooding.
Inundation Areas show the areas that would likely be flooded if a dam were to fail.

Description: Rainy Day Failures:
Overtopping: This is often caused by prolonged periods of rainfall leading to water levels exceeding the dam's capacity.
Inadequate Spillway Capacity: If spillways are not designed to handle extreme inflows, overtopping can occur.
Flooding: Heavy rains, especially when combined with snowmelt, can lead to unexpected water volume increases, challenging dam structures.
Sunny Day Failures:
Internal Erosion: This can occur through piping or seepage, where water finds a path through the dam's structure or foundation, potentially leading to failure even in fair weather.
Structural Weakness: Cracks or defects in the dam's body or foundation that aren't apparent until a failure occurs.
Seismic Activity: Earthquakes can cause dam failures regardless of weather conditions, although this is less predictable.
