Halcrow have developed ISIS Free so that it offers an integrated 1D and 2D modelling software package. ISIS Free has all the same features as ISIS Professional and ISIS 2D which enable you to confidently apply it to smaller river modelling projects and to tackle different types...

HEC-RAS is designed to perform one-dimensional hydraulic calculations for a full network of natural and constructed channels. The following is a description of the major capabilities of HEC-RAS.
MIKE 11 is synonymous with top quality river modelling covering more application areas than any other river modelling package.
GeoHECRAS speeds up HEC-RAS model creation using AutoCAD and GIS data sources. Work directly off of Google Maps, viewing and editing the model in 2D and 3D. Automated cross section cutting reduces time in building a model.
SOBEK is a powerful modelling suite for flood forecasting, optimisation of drainage systems, control of irrigation systems, sewer overflow design, river morphology, salt intrusion and surface water quality.

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.

MIKE FLOOD is the most complete toolbox for flood modelling available. It includes a wide selection of 1D and 2D flood simulation engines, enabling you to model virtually any flood problem whether it involves rivers, floodplains, floods in streets, drainage networks, coastal...
MIKE 21 is the ultimate Swiss army knife of coastal modelling. If you need to simulate physical, chemical or biological processes in coastal or marine areas, MIKE 21 almost certainly has the tool you need.
Free, open-source storm sewer design and analysis: Rational method, Manning capacity, HGL/EGL backwater and HEC-22 inlets, with import from Hydraflow and Civil 3D files.
