Arc Hydro is a community, data model, set of tools, and workflows to support the GIS side of hydrologic and hydraulic (H&H) analyses. Learn how to apply the Arc Hydro data model while running workflow-driven tools in a watershed modelling application. Starting with a good quality digital elevation model (DEM), you will conduct terrain preprocessing to hydrologically condition the DEM. The next step will involve input into stream drainage network identification, followed by catchment delin...

The new Canadian Hydrospatial Network (CHN) is set to replace the National Hydrographic Network (NHN) for Canada. Designed for improved use in hydrological models, the CHN is analysis ready with full-network traversing ability, and value-added attributes such as stream order. The CHN is also created from higher-resolution source data and better aligned to elevation than the NHN, where possible, and has been streamlined for production and maintenance.Work is on-going to refine methods a...
Subsea acoustic sensors, including multibeam sonars and sub bottom profilers, provide users with a variety of data types to improve our understanding of the marine environment and effectively manage important resources. This includes bathymetry, which is a foundational layer for analysis, but also information on the bottom reflectivity to characterize sediment types, water column data to map mid-water material and organisims by providing a view from the sensor to the floor of our rivers and l...
Water is one of our most vital resources, and its management is becoming increasingly complex in the face of climate change, population growth, and competing demands from agriculture, industry, and municipalities. This panel will delve into how geospatial technologies are revolutionizing water policy by providing the data-driven insights needed for smarter decision-making.Join leading experts from academia, provincial and federal gov...
The government of Alberta manages the production of riverine flood studies under the provincial Flood Hazard Identification Program, to assist communities in keeping Albertans safe and protecting their properties from floods. Flood maps improve public safety, support emergency management, and help us build safer and more resilient communities. The government of Alberta also manages the production of alluvial fan studies to help Albertans learn about flood risks in the steep terrain of Alberta...
The Riparian Web Portal (www.riparian.info) is an award-winning project, launched in 2021 by Alberta’s watershed community. This dynamic online space empowers Albertans to enhance riparian health through interactive access to comprehensive data and resources. It serves a crucial role in advancing the riparian health objectives pursued by various watershed groups.At its core, the portal integrates innovative GIS-based assessments from six watershed agencies, covering over 60,000 km of r...
Algal blooms, typically consisting of cyanobacteria which can produce harmful toxins, are a recurring problem on lakes around the world. Although Alberta has long-term sampling programs on selected lakes, monitoring is limited in time and space. Satellite remote sensing offers a way to monitor cyanobacteria blooms across the entire ice-free season and track spatial patterns of bloom development, dynamics, and spread across lakes. The Alberta Biodiversity Monitoring Institute (ABMI), Alb...
Discrete Global Grid systems (DGGS) are emerging spatial data structures widely used to organize geospatial datasets across scales. While DGGS have found applications in various scientific disciplines, including atmospheric science and ecology, their integration into physically based hydrologic models and Earth System Models (ESMs) has been hindered by the lack of flow-routing datasets based on DGGS. In response to this gap, this study pioneers the development of new flow routing datasets usi...

Reduced snowpack in the Rockies presents a severe drought risk for Southern Alberta. Mountain snowmelt in the Bow and Oldman basins maintains reservoir levels, crop irrigation, municipal and industrial supply, and ecosystem services. As climate and consumption pressures increase, accurate snow water equivalent (SWE) data is crucial for water supply forecasts, which impact allocations and emergency drought measures. Field snowpack monitoring does not provide accu...
