This project will involve close collaboration with the successful offeror and the U.S. Army Corps of Engineers (USACE), Engineer Research and Development Center (ERDC). This project will involve adding the navigation attributes to acoustic fields and potentially electric fields within the OpenFOAM framework, while still computing hydraulic variables. The resulting data set will include a sound field, a flow field, various navigation attributes that are found to impact either the acoustic and/or flow fields, and electrical field as appropriate. A field site with supporting geometry, acoustic data, lock operations data, navigation data, and AIS data will be provided by the USACE. The successful offeror will be responsible for processing ambient and intentional (that is the acoustic deterrent) acoustic and hydrological data as appropriate. Operations, navigation, and AIS data will be processed by USACE, which would include the removal/recoding of vessel identifications.
