| Abstract: | A GIS-based fully-distributed model, IMWEBs-Wetland (Integrated Modelling for
Watershed Evaluation of BMPs—Wetland), is developed to simulate hydrologic processes of
site-specific wetlands in an agricultural watershed. This model, powered by the open-source GIS
Whitebox Geospatial Analysis Tools (GAT) and advanced database technologies, allows users to
simulate and assess water quantity and quality effects of individual wetlands at site and watershed
scales. A case study of the modelling system is conducted in a subbasin of the Broughton’s Creek
Watershed in southern Manitoba of Canada. Modelling results show that the model is capable of
simulating wetland processes in a complex watershed with various land management practices.
The IMWEBs-Wetland model is unique in simulating the water quantity and quality effects of
individual wetlands, which can be used to examine location-specific targeting of wetland retention
and restoration at a watershed scale. |
