Carlson Precision 3D Hydro (P3D Hydro) is a powerful 3D engineering design software that combines ease-of-use with precise hydrologic and hydraulic modeling. Users can delineate drainage areas, calculate runoff from surface models, and size culverts accurately within a full 3D environment.
The software includes a Headwall Library and drag-and-drop tools to quickly select and place headwalls and endwalls. Culverts and headwalls can be moved with full DTM restoration, while upstream and downstream grading is fully supported. P3D Hydro integrates seamlessly with Carlson Civil Suite, AutoCAD, and MicroStation, offering multithreaded, 64-bit performance for large models.
Advanced 3D shaders and multithreading increase speed and visualization quality, while multiple barrel options and solid modeling provide precise engineering results. P3D Hydro combines innovative technology with user-friendly workflows to accelerate stormwater, drainage, and pond design projects.
