| New Feature / Category | Description & Impact | | :--- | :--- | | | Enabled direct application of spatially and temporally variable "Rain-on-Grid" and infiltration methods (SCS, Green & Ampt) to entire model domains, significantly enhancing accuracy for flood forecasting and hydrologic modeling. | | 2D Bridge & Pump Station Modeling | Allowed modeling of bridges and pump stations directly within 2D Flow Areas by processing bridge hydraulics into a family of curves for dynamic momentum equations, and enabling pump stations to be placed for precise urban drainage and complex system simulations. | | 3D Graphics/Animation Viewer | Introduced a native 3D viewer and 3D Google Earth export tool to create high-quality animations and perspective plots for analyzing results and presenting findings. | | HEC-RAS Mapper Editing Tools | Added powerful editing tools in the GIS-based Mapper interface for modifying terrain (cut/fill) and structuring data, including a built-in "Raster Calculator" for direct geospatial analysis. | | Wind Forces | Added the ability to apply wind shear forces, making 1D and 2D models more robust for large bodies of water like reservoirs or coastal areas where wind-driven setup is significant. | | 64-bit Computational Engines | Transitioned exclusively to 64-bit computational engines for faster run times and significantly larger datasets, but requires users to upgrade to a 64-bit Windows operating system. |

Version 6.0 introduced the ability to model bridges directly within 2D flow areas. The bridge’s hydraulic properties are processed into a family of rating curves, similar to the 1D approach, and these curves are used to compute the forces due to the bridge based on flow through the opening as well as over the top of the bridge. This feature is particularly valuable for urban flood modeling where bridges significantly affect flow patterns.

A more streamlined RAS Mapper experience.

HEC-RAS 6.0 introduced significant computational overhead due to 2D sediment features. The following specifications are recommended for a stable operating environment:

HEC-RAS 6.0 is a major update to the US Army Corps of Engineers' modeling software. While subsequent versions have been released, 6.0 represents a pivot point focusing on accelerating 2D simulations and allowing for more complex, integrated hydraulic scenarios.
