hydrological-modeling
Hydrological modeling uses mathematical frameworks to simulate and predict the movement, distribution, and quality of water across landscapes and through plant systems. For plant scientists, these models are essential for understanding how water availability shapes vegetation dynamics, root water uptake, and ecosystem productivity. They also enable researchers to forecast how plants and plant communities will respond to changes in precipitation patterns, drought cycles, and land use.

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.
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.
