GDOT Bridge Hydraulics

Bridge construction often necessitates placement of temporary features such as rock jetties and coffer dams in stream and river channels during the construction process. However, there is no existing guidance or standard method for evaluating the potential effects of these temporary construction features on hydraulics, bank stability, and biological habitats. This research aims to provide a physically based tool for evaluating the influence of temporary channel obstructions on instream hydraulics and the potential geomorphic and ecological effects.
