Modelling Philosophy IP3
Research basins were at different level of modelling at beginning of
IP3
Goal was to get all research basins to the same level
Start by setting up model on 1 grid square – 1 GRU basecase for all
basins (ie. Use data from single met station)
Get initial streamflow results using a generic parameter set for all
basins (runs shown here use MESH 1.0.0h)

Modelling Philosophy IP3
This allowed for initial contact with field personnel from
research basins
Find out the data that is available, perhaps suggest others
Some basins (Scotty, Wolf, Trail Valley) are more developed

Modelling Philosophy IP3
Teams of modellers working with field personnel of each
research basin to develop detailed modelling
We have been doing this with Bill Quinton on the Scotty Creek
research basin
We recommend following the same path with other research
basins

Possible next steps on Scotty: tile connector
•uses a tile connector to allow transfer of runoff
between peat plateau and fens, and peat plateaus and
isolated bogs
•can have one receiving class and two source classes
•transfer is based on the square-root of the ratio of the
area of the receiving land class divided by that of the
source land class
Grid element with tile diversion
Source Tile 1
Source Tile 2

Next steps
Make all files (MESH executable, basin files) available to all
researchers via the IP3 ftp site
Apply 1 km grid square to all basins:
Need to obtain DEMs for each basin
Have to decide how to interpolate data
Get more than just Met data for each research basin (ie. Soil
moisture, soil temperature, ET, snow information, etc.)
