Hydrological data (streamflow, evapotranspiration) in Saint John River Basin

MESH model is used for calibration/ validation of the streamflow. MESH is a physics-based, land-surface hydro- logical modelling system developed by Environment and Climate Change Canada. MESH performs both water and energy balances and is best suited to cold-region, large-scale catchments due to its ability to simulate snow processes, such as snow accumulation, redistribution, and melt. MESH is used to simulate important hydrological processes (like runoff generation, evapotranspiration, and soil moisture).

The following input data were used for hydrological modelling:

- Meteorological data: For model calibration and validation for historical period, bias corrected WFDEI-GEM-CaPA data is used ( https://doi.org/10.20383/101.0111 ). The dataset is available from 1979-2016 and has seven forcing (precipitation, longwave radiation, shortwave radiation, wind speed, air temperature, barometric pressure and specific humidity).

- For future meteorological dataset, bias corrected CanRCM4-WFDEI-GEM-CaPA dataset is used ( https://doi.org/10.20383/101.0162 ). The dataset is available from 1951-2100.

- Drainage basin data: Digital Elevation data (Geobase database as Canadian Digital Elevation Data), Landcover data ( http://cec.org/tools-and-resources/map-files/land-cover-2010-landsat-30m ), soil data (Soil Landscapes of Canada (version 2.2), eco-regions shape files for Canada and North America, and other relevant data was obtained from different sources. The drainage basin was created using GreenKenue.

- Hydrological data: The ECCC active hydat stations for Saint John Basin is used for the discharge data. The reservoir inflow/outflow data for GrandFalls, Beechwood, Tobique and Mactaquac is provided from New Brunswick power.

For Core Modelling, the data is generated under Current generation hydrological modelling theme which aims to perform hydrological modelling and future climate change scenarios runs in Saint John River Basin.
