Abstract. Model intercomparison studies are carried out to test and compare the simulated outputs of various model setups over same study domain. The Great Lakes region is such a domain high public interest as it not only resembles challenging with its transboundary location, strong lake effects, regions human impact but also one most densely populated areas in USA Canada. This brought together wide range researchers setting up their models choice highly standardized experimental setup using...
Abstract. Environment and Climate Change Canada has initiated the production of a 1980–2018, 10 km, North American precipitation surface reanalysis. ERA-Interim is used to initialize Global Deterministic Reforecast System (GDRS) at 39 km resolution. Its output then dynamically downscaled by Regional (RDRS). Coupled with RDRS, Canadian Land Data Assimilation (CaLDAS) Precipitation Analysis (CaPA) are produce analyses. All systems close operational model versions configurations. In this study,...
Abstract Dry detention ponds are commonly implemented to mitigate the impacts of urban runoff on receiving water bodies. They currently rely static control through a fixed limitation their maximum outflow rate. Real-Time Control (RTC) allows optimizing performance by manipulation an outlet valve. This study developed several enhanced RTC scenarios dry pond located at small catchment near Québec City, Canada. The catchment's quantity and TSS concentration were simulated SWMM5 model with...
Hydrologic model intercomparison studies help to evaluate the agility of models simulate variables such as streamflow, evaporation, and soil moisture. This study is third in a sequence Great Lakes Runoff Intercomparison Projects. The densely populated Lake Erie watershed studied here an important international lake that has experienced recent flooding shoreline erosion alongside excessive nutrient loads have contributed eutrophication. Understanding sources pathways flows critical solve...
Abstract. From 19 to 22 June 2013, intense rainfall and concurrent snowmelt led devastating floods in the Canadian Rockies, foothills downstream areas of southern Alberta southeastern British Columbia, Canada. Such an event is typical late-spring cold-region mountain headwater, combining precipitation with rapid melting late-lying snowpack, represents a challenge for hydrological forecasting systems. This study investigated factors governing ability predict such event. Three sources...
Abstract. This work explores the potential of distributed GEM-Hydro runoff modeling platform, developed at Environment and Climate Change Canada (ECCC) over last decade. More precisely, aim is to develop a robust implementation methodology perform reliable streamflow simulations with model large partly ungauged basins, in an efficient manner. The latest version combines SVS (Soil, Vegetation Snow) land-surface scheme WATROUTE routing scheme. has never been evaluated from hydrological point...

The covers basins Laurentian Great Lakes Ottawa River extends over period 2001–2018. data consist all variables (hourly fluxes state variables) related to water balance GEM-Hydro’s land-surface scheme (including precipitation, surface sub-surface runoff, drainage, evaporation, snow equivalent,...
ABSTRACT Understanding deep percolation dynamics is crucial for effective groundwater management. This particularly important in cold regions significantly affected by soil freezing and snow. The scarcity of direct measurements the insufficient focus on has limited previous research. study addresses these gaps measuring placing four drainage lysimeters inside three large experimental plots Québec, Canada. classified 67 measured events into two categories: those starting (36) warm (31)...
This work explores the performances of hydrologic model Hydrotel, applied to 36 catchments located in Province Quebec, Canada. A local calibration (each catchment taken individually) scheme and a global (a single parameter set sought for all catchments) are compared differential split-sample test perspective. Such methodology is useful gain insights on model’s skills under different climatic conditions, view its use climate change impact studies. The was calibrated using both schemes five...
AbstractDry detention ponds are commonly implemented to mitigate the impacts of urban runoff on receiving water bodies. They currently rely static control through a fixed limitation their maximum outflow rate. This study investigated performance several enhanced management strategies for dry pond located at outlet small catchment near Québec City, Canada. Among scenarios studied some previously developed real-time (RTC) strategies, and new operating rules relying daily manual adjustment...

Lakes and reservoirs have critical impacts on hydrological, biogeochemical, ecological processes, they should be an essential component of regional-scale hydrological eco-hydrological models. This is particularly important in Canada with its tens thousands lakes. Past large-scale hydrologic modelling efforts tend to either ignore the all lakes or explicitly simulate behaviour only largest a watershed. research derives suite Pan-Canadian subwatershed-based lake river routing GIS products at...
Abstract Ensemble rainfall forecasts are of high interest for decision making, as they provide an explicit and dynamic assessment the uncertainty in forecast. However, hydrological forecasting, their low resolution currently limits use to large watersheds. To bridge this gap, various implementations a spatial statistical downscaling method were compared, bringing Environment Canada's global ensemble from 100 × 70‐km down 6 4‐km while increasing each pixel's variance preserving its original...
This paper explored various configurations of the ensemble Kalman filter, GR4J hydrological model, and Global Environmental Multiscale (GEM) atmospheric model in order to maximize skill forecasts for Lake Champlain–Richelieu River watershed. In open-loop mode, represented very well observed streamflow (Nash–Sutcliffe value above 90%). It sufficed assimilate data obtain a reliable skillful analysis streamflow; assimilation snow water equivalent (SWE) information did not bring additional...
As part of the National Hydrological Services Transformation Initiative, Environment and Climate Change Canada (ECCC) designed implemented Surface River Prediction System (NSRPS) in order to provide surface river flow analysis forecast products across Canada. Within NSRPS, Canadian Land Data Assimilation (CaLDAS) produces snow analyses that are used initialise land model, which turn is force routing component. Originally, CaLDAS was improve atmospheric forecasts with less focus on...
