SEE provides technical expertise in hydrologic and hydraulic (H&H) analysis to support stormwater management, infrastructure design, and flood risk assessment. Our team applies industry-standard models and methods to simulate rainfall-runoff processes, streamflow, and stormwater conveyance under a range of conditions.
SEE staff are experienced in watershed characterization, flow modeling, and system performance evaluation using tools such as HEC-RAS, SWMM, FHWA HY-8 for culvert design and evaluation, and GIS-based analysis. We assess existing drainage networks, evaluate proposed infrastructure, and develop design solutions that meet regulatory requirements while minimizing environmental impacts.
Our H&H services include:
● Hydrologic modeling to predict runoff and peak flows;
● Hydraulic modeling of streams, culverts, and stormwater systems;
● HY-8 culvert analysis and design;
● Floodplain and stormwater system capacity analysis;
● Design of stormwater management and mitigation measures; and
● Support for permitting, regulatory compliance, and infrastructure planning.
Through these analyses, SEE helps clients design efficient, resilient, and environmentally responsible stormwater and water resource management solutions.
