For many of our projects, completing the hydrology/hydraulics investigation and report is an integral component completed in-house by DJ&A personnel. We regularly complete the computer modeling for these studies and analyses on bridges and culverts. This has included HY8, HEC-RAS, HEC-II, WSPRO modeling.  We have also completed bridge scour analysis using the HEC-RAS program and routinely calculate the hydraulic effects for bridge and culvert design.
