Description#
The mesoscale Hydrologic Model (mHM) developed by the Dept. Computational Hydrosystems at UFZ is a spatially explicit distributed hydrologic model. It is implemented in the Fortran programming language and can be easily installed as software using the conda package manager. The model concept uses grid cells as a primary hydrologic unit, and accounts for the following processes: canopy interception, snow accumulation and melting, soil moisture dynamics, infiltration and surface runoff, evapotranspiration, subsurface storage and discharge generation, deep percolation and baseflow and discharge attenuation and flood routing. The model is driven by hourly or daily meteorological forcings (e.g., precipitation, temperature), and it utilizes observable basin physical characteristics (e.g., soil textural, vegetation, and geological properties) to infer the spatial variability of the required parameters.
The main feature of mHM is the approach to estimate parameters at the target resolution based on high resolution physiographic land surface descriptors (e.g., DEM, slope, aspect, root depth based on land cover class or plant functional types, leaf area index, soil texture, geological formation type).
The model has already successfully completed a sprint as part of the natESM project. Findings and solutions from the sprint can be found in the documentation.
