Canada1Water: Hydraulic parametrized integrated soil, bedrock and peatlands datasets.
Kessel ED, Frey SK, Lapen DR, Geng X, Russell HAJ
Summary
PubMedWhy it matters This matters because understanding how water moves through soil and peat directly affects the health of every plant, wetland, and watershed in Canada — influencing flooding risks, drought resilience, and the water that feeds gardens and farms across the country.
Scientists created a giant, high-detail map covering all of Canada that shows how water soaks into different types of ground — regular soil, exposed rock, and boggy peatlands. They used information about soil texture and density to calculate how quickly water flows through or gets stored in the ground. This kind of map helps predict floods, droughts, and how healthy wetland plants like mosses and sedges will be as the climate changes.

Canadian researchers built a detailed, nationwide map of soil, rock, and peatland water-holding properties to better model how water moves through the landscape — from rainfall down through the ground and into rivers and streams.
Key Findings
The dataset covers all Canadian provinces and territories at 250-meter resolution, organized into 7 underground layers with the top two spanning 0–1 meter below the surface.
Peatlands were classified into three decomposition levels (moderately, decomposed, and well-decomposed peat), each with different water-storage properties critical for wetland ecosystems.
The final product is an 18-band raster map integrating mineral soils, bedrock outcrops, and peatlands — extending into shared watersheds with the United States for cross-border water modeling.
