I am a postdoc with the Centre for Hydrology and Global Water Futures (GWF) at the University of Saskatchewan in Saskatchewan, Canada. I have an interest in hydrological modelling and related fieldwork and I am currently working on the next generation core modelling group developing the Canadian Hydrological Model (CHM).
In my free time I take photos of wildlife and nature with my wife which you can see here: marsh.photos
I can be contacted at chris.marsh (at) usask.ca or through LinkedIn.
The Canadian Hydrological Model (CHM) is a modular unstructured mesh based approach for hydrological modelling. It can move between spatial scale, temporal scale, and spatial extents. It is designed for developing and testing process representations for hydrological models. Further details can be found on github
Mesher is a multi-objective unstructured mesh generation software that allows mesh generation to be generated from an arbitrary number of hydrologically important features while maintaining a variable spatial resolution. Triangle quality is guaranteed as well as a smooth graduation from small to large triangles. Including these additional features resulted in a better representation of spatial heterogeneity versus classic topography-only mesh generation. Further details can be found on github
I have my code hosted on Github.
