Advancing Communities by Reducing Flood Risk

In order to mitigate against vulnerabilities, first you need to understand your risk. T&M has extensive experience helping government agencies identify flood risk, plan mitigation strategies, and develop and implement sound land use strategies for resilient growth. Our team models and maps thousands of miles of rivers and streams every year – from the flat terrain of the coastal plains to the rural woods, farms, and urban areas of the Appalachian Mountains.

Our team of water resource engineers and Certified Floodplain Managers have extensive hydrologic and hydraulic modeling experience in analyzing fluvial (riverine) and pluvial (flash floods or surface water) flooding using a variety of modeling methods.

Our modeling is fully integrated with GIS for seamless model development and mapping of the impacts. Using these results, we assist clients with risk assessment and mitigation strategies.
