Davis-Monthan Air Force Base Channel Design

Davis-Monthan Air Force Base (Golf Links Road and Wilmot Road), City of Tucson, Pima County, Arizona
  • Hydrologic and hydraulic analysis

The Davis-Monthan Air Force Base began storage of military aircraft shortly after World War II and has grown to be the the world’s largest military aircraft boneyard.

Entellus was selected to perform hydrologic and hydraulic analyses to mitigate potential damage to the solar facility built on the Air Force base. Our solution included on-site channel modifications, like connecting to a nearby channel, that exceeded both the City of Tucson and the U.S. Department of Defense’s design standards. Additionally, we determined flows for the Davis-Monthan Channel, and the adjacent Tucson Diversion Channel, whose drainage area included the 309th Aerospace Maintenance and Regeneration Group (309 AMARG), housing developments, and shopping centers. We utilized HEC-RAS to demonstrate our compliance with drainage standards and freeboard requirements – resulting in a final design that would eliminate the scour and damage to the solar facility and provide an outfall for the Davis-Monthan Channel.
