Sediment Transport & Morphology Tools
Sediment moves the problem: aggradation, degradation, reservoir sedimentation and channel change. The list includes river and coastal models with sediment and morphology modules — HEC-RAS, SRH-2D, BASEMENT, Iber, Delft3D FM and openTELEMAC — plus catchment and water-quality models that track sediment loads.
Delft3D FM
Open Source
Deltares' open flexible-mesh suite for rivers, estuaries and coasts — hydrodynamics to morphology.
EFDC+
Freemium
Open-source 3D hydrodynamics and water quality — the EFDC lineage modernised, with a commercial GUI option.
HEC-RAS
FreeVerified
The world's most used hydraulic model: free 1D/2D river analysis, sediment, water quality and flood mapping.
Iber
Free
Free Spanish 2D hydraulic model — flow, turbulence, sediment and habitat modules behind a full GUI.
SRH-2D
Free
The US Bureau of Reclamation's free 2D river model — FHWA's preferred engine for bridge hydraulics.
SWAT+
Open Source
The USDA watershed model for land use, sediment and nutrients — continuous simulation at catchment scale.
WASP
Gov-Public
EPA's Water Quality Analysis Simulation Program — eutrophication, toxics and sediment in rivers and estuaries.
openTELEMAC
Open Source
EDF's open-source finite-element suite for free-surface flow — 2D/3D rivers, estuaries, waves and sediment.
