Understanding water behavior is foundational to nearly every project High Water Mark touches. We specialize in hydrology and hydraulics (H&H) that bring clarity to complexity — whether assessing peak flows in urban basins or modeling a 100-year floodplain under future conditions.
Our H&H services blend cutting-edge modeling with a grounded understanding of watershed dynamics, infrastructure performance and regulatory standards. We use tools like HEC-RAS, HEC-HMS and Storm Water Management Model (SWMM) to simulate how water moves across land, through systems and under stress.
Advances in technology continually expand the applications of models in water resource engineering applications. High Water Mark uses computer models to simulate the flow and movement of water in streams, rivers and other water bodies.
Our modeling goes beyond simple simulations to include more complex processes, such as interactions between the water and the surrounding environment, sediment transport, and water quality.
Clients rely on our multidisciplinary approach and portfolio of hydrologic and hydraulic engineering services, including:
What sets us apart isn’t just our software expertise — it’s our ability to communicate results with precision and purpose. Our models support design decisions, litigation strategy and capital planning by offering not just data, but insight.
We don’t just model what happened. We explain why. Whether you’re a city planner needing to validate culvert capacity or a legal team reconstructing storm event causality, High Water Mark delivers H&H analyses that hold water.
