Prof. John Pomeroy will be giving a webinar on The Impact of Wetland Drainage on the Hydrology of a Northern Prairie Watershed to the Association of State Wetland Managers on Monday November 17th at 2 pm Saskatchewan time (1 pm Mountain time).

The talk will detail CH research at Smith Creek, with respect to the hydrological implications of its changing climate and the implications of wetland drainage, as investigated through hydrological model simulations.

If you would like to know more about this research, the webinar will be available at this link.  Thanks are due to co-authors Stacey Dumanski, Logan Fang, Kevin Shook, Cherie Westbrook and Xulin Guo.

Abstract: The Prairie Hydrological Model simulates blowing snow redistribution, snowmelt, infiltration to frozen soils and the fill and spill of networks of prairie wetlands.  The model was used to simulate the hydrology of Smith Creek, Saskatchewan, Canada with various wetland extent scenarios.  This model simulation exercise shows that prairie wetland drainage can increase annual and peak daily flows substantially, and that notable increases to estimates of the annual volume and peak daily flow of the flood of record have derived from wetland drainage to date and will proceed with further wetland drainage.
