Effective 2D modeling starts long before you open HEC-RAS.
Reliable results depend on accurate terrain data, properly defined drainage basins, analysis of land cover, and precipitation methods suited to the project area. Small data inconsistencies can have a big impact on how we understand flow depth, velocity, and potential flood impacts.
At Ancalle Engineers, we use technical expertise and detailed analysis to help understand how water moves across the landscape.
