WATFLOODTM

www.watflood.ca

WATFLOODTM is an integrated set of computer programs to forecast flood flows for watershed having response times ranging from one hour to several weeks. Continuous simulation can be carried out by chaining up to 100  events. A shell program organizes all the menus used for data input and correction functions and acts as the manager for the hydrologic model SPL and utility programs. The emphasis of the WATFLOOD system is on making optimal use of remotely sensed data. Radar rainfall data, LANDSAT or SPOT land use and/or land cover data can thus be directly incorporated in the hydrologic modeling (Kouwen, 2010). 

It is a distributed, partially physically-based (also partially conceptual) hydrologic model.  Our research group contributes to the development of the WATFLOOD model, in particular for remote, northern hydrological landscapes.  The model is being used to simulate the hydrology of all watersheds contributing flow to the Province of Manitoba for both short-term and long-term hydrologic studies.

isoWATFLOOD & REMOiso

isoWATFLOOD is a specialized module written for the WATFLOOD hydrologic model that enables the use of isotope tracers in watershed hydrology (Stadnyk-Falcone, 2008).  Our group continues to add functionality to this module, using it to trace sources of water at the watershed scale and for improved hydrologic calibration over large domains (greater than 1000 km2) where input data are sparse and coarse resolution.   

There is currently work being done to interface isoWATFLOOD with REMOiso (an isotopically-enabled regional circulation model devleoped in Europe) to provide distributed d18O in precipitation inputs for hydrological simulation of d18O tracers. http://people.su.se/~cstur/remo_iso.htm

Green Kenue

http://www.nrc-cnrc.gc.ca/eng/ibp/chc/software/kenue/green-kenue.html

Green KenueTM (formerly EnSim Hydrologic) is an advanced data preparation, analysis, and visualization tool for hydrologic modellers. It provides a state-of-the-art interface, integrating environmental databases and geospatial data with model input and results data. Green KenueTM provides complete pre- and post-processing for the WATFLOOD and HBV-EC hydrologic models. Also included is a 1D "reach scale" unsteady hydrodynamic flow solver, Gen1D. (NRC, 2011)

Green Kenue is used by our group as a pre- and post-processing system and graphical user interface for WATFLOOD. 

Stella

www.iseesystems.com

Stella is an object oriented, systems modelling approach to problem solving.  Our group has been using Stella to develop a coupled isotope-lake hydrology model for two inland lakes (L373 and L626) in the Experimental Lakes Area (ELA) of north western Ontario.
