While surface water hydrology and hydraulics (H&H) are our only fields of practice, our diversity within these fields is unmatched. WRCS has project experience ranging from dam and channel design to the complex modeling of two-dimensional, time variant hydraulic systems. We have performed H&H environmental impact analyses, redefined FEMA floodplains and developed hydrologic and hydraulic design standards and for municipalities.

Here are some of the types of Engineering Design Projects and H&H Investigations WRCS engages in:

• Hydrologic rainfall/runoff watershed simulations, including the derivation of various frequency pre- and post-project flood hydrographs.


• Floodplain analyses and mapping, and preparation of FEMA requests for Letters of Map Revision (LOMR's and CLOMR's).


• Design of channel stabilization measures, including linings, riprap and energy dissipation structures for erosion control.


• Design of dams, channels, retention and sedimentation basins, culverts and bridge crossings with detailed analysis of inlets, outlets and hydraulic structures.


• Hydraulic evaluation of wetlands and estuaries and development of mitigative measures for projects, such as incorporation of wetlands into flood control systems.


• Analysis of Municipal Storm Drain Systems, including design performance and evaluation of operation and maintenance procedures.


• Establishment of meteorologic and stream gaging stations and statistical evaluation of data for water supply yield and hydrologic flow regime determinations
