Lunchtime Seminar on IP3 Modelling – Friday 7 October

The Centre for Hydrology is pleased to present a hydrology seminar by Muluneh Mekonnen, IP3 Post-Doc, from 12:30 to 1:15pm on Friday 7 October 2011, in AGRI 1E69, entitled IP3’s combined top-down and bottom-up modelling approach using MESH and CRHM as complementary modelling platforms
The IP3 (Improving Processes and Parameterization for Prediction in Cold Regions Hydrology) network came to a successful end in September 2011, leaving a legacy of extensive cold regions processes, parameterization and prediction research work.
IP3’s strategic goal was to attain a more comprehensive physical description of cold regions processes and parameterizations, at regional and smaller scales, for improved prediction within hydrological and hydro-meteorological models such as the Cold Regions Hydrological Model (CRHM) and the Community Environmental Hydrology Land-Surface modelling system, known as MESH.
This seminar presents an application of the combined top-down and bottom-up hydrological modelling approach, using MESH and CRHM as complementary modelling platforms, for the South Saskatchewan River Basin (SSRB) and the Upper Assiniboine River Basin (UARB). In addition to cold regions processes, the SSRB and UARB are characterized by the prairie pothole topography that brings in the additional complexity of shrinking and expanding horizontal flow contributing areas.
The seminar will highlight two key points:
1) How to build a model with relatively minimal complexity whose prediction is commensurate with observations, and
2) How to use the Grouped Response Units approach for physically based parameter regionalization.
Feel free to bring your lunch!

CUAHSI Cyber-Seminar

Director of the Centre for Hydrology Prof John Pomeroy will be giving a cyber-seminar on Advancing hydrological processes to better predict hydrology in cold regions, for the US Consortium of Universities for the Advancement of Hydrological Science Inc (CUAHSI), at 3 pm Eastern Daylight Time on Friday, 17 September.
The subject-area will cover results from IP3, DRI and other research from the University of Saskatchewan’s Centre for Hydrology.

Seminar Series: The Canadian Rockies Snow and Ice Initiative

The Canadian Rockies Snow and Ice Initiative announces its 2010 Speaker Series! Our first presentation will be Tuesday evening, 26 January, at 7:00 PM in the Canmore Collegiate High School Theatre, Canmore, Alberta. Following the presentation by Dr. John Pomeroy, we will have an audience discussion on “What is the CRSI and what can it mean for Canmore and the Bow Valley?” followed by refreshments and a chance to mingle.
Five additional evening presentations by Canadian and international snow and ice researchers will follow from February to May. You can download the full program here.
