PHyDAP - Prairie Hydrology Design and Analysis Product
Federated Research Data Repository / dépôt fédéré de données de recherche
Shook, Kevin R.; He, Zhihua; Spence, Christopher; Whitfield, Colin; Pomeroy, John W — 2023-04-12 The PHyDAP datasets are outputs of CRHM virtual basin models forced by long-term climate data sets, for more than 4,000 basins on the Canadian Prairies. The intent is that the CRHM model outputs will be used for forcing small-scale hydraulic models in the region. By running the hydraulic models for long time periods, the effects of changes in local hydraulics, and/or climate change on return-period flows and/or flooded areas can be assessed. The basins used for the CRHM models are derived from HydroSHEDS (https://www.hydrosheds.org/) as described by Lehner and Grill (2013). The virtual basin models are based on the basin classification described in Wolfe et al. (2019). An example of the use of the virtual basin models is given by Spence et al. (2022). The use of long-term hydrological model outputs to force small-scale hydraulic models is demonstrated by Altraide (2020).

Canadian Prairie Watershed Classification
Federated Research Data Repository / dépôt fédéré de données de recherche
Wolfe, Jared; Whitfield, Colin J.; Shook, Kevin R.; Spence, Chris — 2024-03-27 Shapefile detailing classified prairie watersheds (n = 4175) according to physiographic characteristics. These characteristics were assembled from a variety of sources, including remote sensed data and government databases. Variables included climatic (annual precipitation, potential evapotranspiration), physical (slope, elevation), surficial geology, wetland (density, size distribution), and land cover/use data. Watersheds were classified using a hierarchical clustering on principal components analysis. As a result, seven distinct classes of watersheds were identified. The dataset defines two classifications schemes: (1) Integrated Watershed Classification, and (2) Land Cover Watershed Classification. The schemes differ as the latter was performed without climatic variables. As such, the land cover approach is suited for applications where local climate is forced using other data sources (e.g., hydrological modelling). The integrated classification is suited for general applications.

Virtual Watershed Model Simulations for Typified Prairie Watersheds in Pothole Till
Federated Research Data Repository / dépôt fédéré de données de recherche
He, Zhihua; Spence, Christopher; Shook, Kevin R.; Pomeroy, John W; Whitfield, Colin; Wolfe, Jared — 2024-03-27 The dataset is comprised of inputs to and outputs from the Cold Regions Hydrological Model (CRHM) when it was run as a virtual model of the Pothole Till class, as defined by Wolfe et al. (2019). These watersheds represented typified prairie watersheds based on physiogeography and coherent response to environmental change. Model parameters were informed by the results of Wolfe et al. (2019). The .prj files necessary to run the virtual models are included in the dataset. Climate forcing data are from the Adjusted and Homogenized Canadian Climate Dataset from a cohort of stations contained within each watershed class and cover a period from 1960-2006. There are a series of wetland drainage scenarios that progressively reduced the wetland depression area and storage capacity by increments of 10%. Model output includes hourly catchment outflow, and depression water storage in the HRUs for the baseline and each scenario. https://creativecommons.org/licenses/by/4.0/

Virtual Watershed Model Simulations for Typified Prairie Watersheds in Seven Basin Classes
Federated Research Data Repository / dépôt fédéré de données de recherche
He, Zhihua; Shook, Kevin R.; Spence, Christopher; Pomeroy, John W; Whitfield, Colin — 2025-01-20 The dataset is comprised of inputs to and outputs from the Cold Regions Hydrological Model (CRHM) when it was run as a virtual model of the seven prairie basin classes, as defined by He et al. (2023). These watersheds represented typified prairie watersheds based on physiogeography and coherent response to environmental change. Model parameters were informed by the results of He et al.

Climate forcing data are from the Adjusted and Homogenized Canadian Climate Dataset from a cohort of stations contained within each watershed class and cover a period from 1960-2006. There are a series of climate sensitivity scenarios that include applying a delta method to the original climate data (i.e., 1°C increments of warming, and -20%, +10%, +20% and +30% of precipitation). Model output includes hourly catchment outflow, and depression water storage in the HRUs for the baseline and each scenario. There are also a series of wetland drainage scenarios that progressively reduced the wetland depression area. https://creativecommons.org/licenses/by/4.0/
