Some projects require taking a step back to look at the big picture with respect to hydrology and hydraulics in order to maintain the functionality of a stormwater management system. This is often the case with bridge replacement projects over streams. Ciorba Group can take an existing hydraulic model and modify it to examine the potential effects of a new bridge crossing over a river or creek. When an existing model has not yet been created, or we have the expertise to use collected stream survey data to create a new model and calibrate it to match existing conditions before investigating any potential modifications. This updated hydraulic model can then be used as a tool to compare alternatives and ultimately design the final improvements.
