What is GeoHECHMS?
GeoHECHMS greatly speeds up the creation, analysis, and review of stormwater models. It automates subbasin delineation, curve number (CN) computation using land use and soils maps, and lag time (time of concentration) computation. GeoHECHMS is a data wrapper to the industry-standard US Army Corps of Engineers HEC-HMS software using an AutoCAD compatible graphical user interface. Quickly compare different scenarios and alternatives, such as pre-development with different post-development designs. Rapidly construct, design, analyze and compare detention and retention ponds. Both US and metric (SI) units are supported.
Work Faster with Automated Workflows
Easy to Learn and Use
Interact graphically with all HEC-HMS model elements. Effortlessly create and edit subbasins, detention ponds, routing reaches and other model elements by clicking and dragging. Uncomplicated dialog boxes allow easy data entry and review.
Unlimited Undo and Redo
Correct mistakes easily with unlimited Undo and Redo capability. Experiment with different engineering and management decisions. Rollback changes one at a time or select a group of changes from a visual selection list.
Expert Technical Support
Toll-free unlimited technical support by experienced HEC-HMS stormwater modelers is just a phone call away. Quickly resolve your stormwater modeling questions and complete your engineering project—our skilled, professional engineers are here to assist you.
Automated HEC-HMS Workflows
Greatly speed up stormwater projects with automated workflows to automatically delineate watersheds, compute curve numbers (CN), compute TOC & lag times, compute % impervious, assign design storms, size detention ponds, and generate engineering reports.
CAD & GIS Integration
Integrate HEC-HMS directly with AutoCAD (including AutoCAD Civil 3D), Bentley MicroStation and ESRI ArcGIS map data. Export completed HEC-HMS models and results to AutoCAD, MicroStation and ArcGIS.
Automated TOC & CN Computations
Automatically compute the longest flow path, assign sheet flow, shallow concentrated flow and channel flow segments. Use included land use mapping and soil mapping to automatically compute composite curve numbers (CN) in minutes.
