Hydrology

There are two main strands to the hydrological drought research being carried in the MaRIUS project.

• Detailed physically-based modelling of drought processes at the catchment scale using the Penn State Integrated Hydrologic Model (PIHM).
• Improving scientific understanding of, and modelling capability for, representing drought processes at the national scale using two hydrological models:
  • Bristol University’s Dynamic TOPMODEL and
  • the CEH Grid-to-Grid (G2G) model

The following schematics show the different hydrological models used in MaRIUS, with the table at the bottom of the page summarising the different models.
