TERRESTRIAL & UNDERWATER LEVEE EVALUATION SYSTEM – Tules
TULES was introduced by DOER in 2005 to address the need for inspection of critical levees and earthen dams. DOER began the development of TULES in 2001 as marine technology was rapidly adapted for homeland security applications around ports and harbors. Our years of work with critical infrastructure and the failure of the Jones tract levee in 2004 drove DOER to look at predicative failure versus emergency response. The failure of levees and the devastation that followed during Hurricane Katrina underscored the need for DOER’s TULES system.
TULES is an acronym: Terrestrial & Underwater Levee Evaluation System. A number of sensing tools are utilized by the system, the results of which provide a “full body” view of the levee structure. Depending upon the resolution desired, voids as small as ping pong balls can be detected but identification of gross defects is the primary objective of a given inspection.
TULES is a dynamic tool which can be scaled up or down depending on the needs of the end user. Instrumentation can be added which will provide information about salinity, temperature, turbidity and other water quality/environmental information in addition to basic structural details.
DOER’s long term goal for TULES is to enter data into a searchable GIS database to which others can add information building a broadly useful database for water managers, environmental scientists and policy makers.
