HGS RESEARCH HIGHLIGHT – Groundwater flow reversal between small water bodies and their adjoining aquifers: A numerical experiment
This recent study uses HydroGeoSphere to investigate groundwater-surface water interactions within “kettle holes” - post glacial landscape features prevalent across Northern Europe and Northern America. These kettle holes are quite similar to lakes, but their smaller size makes them prone to drying out, which results in very dynamic and variable groundwater-surface water interactions, sometimes being subject to groundwater flow reversal between a kettle hole and the adjacent aquifer.
HGS RESEARCH HIGHLIGHT – Effect of topographic slope on the export of nitrate in humid catchments: a 3D model study
Agricultural nutrient runoff refers to the movement of excess nutrients, such as nitrogen and phosphorus, from agricultural lands into water bodies such as rivers, lakes, and oceans. While nutrients are essential for plant growth, excessive runoff can have significant impacts on both human and ecosystem health.
HGS RESEARCH HIGHLIGHT – Impacts of Climate Change and Different Crop Rotation Scenarios on Groundwater Nitrate Concentrations in a Sandy Aquifer
This study by researchers at the University of Guelph investigated the impacts of various crop rotation scenarios and climate change on groundwater nitrate concentrations in a 155 sq-km agricultural sub-watershed in Norfolk County, Ontario.
Water Forecasting Platform Soon to be Launched for the Pembina River Valley
Aquanty is proud to announce that we’re launching a new project in partnership with the Pembina Valley Watershed District (PVWD) and Manitoba Forage and Grassland Association (MFGA) to launch a new hydrologic forecasting platform for the Pembina River Valley.
Manitoba Co-operator - Hydrology forecasting tool drills down to field level
Farmers in the Assiniboine River basin will soon have access to a new tool designed to help them make predictions about water flow at the field level. The tool was developed by the hydrologic modelling firm Aquanty, in cooperation with the Manitoba Forage and Grasslands Association. They are able to combine their model with remote sensing data on things like soil moisture levels and real time groundwater monitoring sensors to set the initial conditions before launching a hydrologic forecast. “Combining that with insights on how water management infrastructure is maintained during floods and droughts and using cloud computing infrastructure, we can readily construct these models and deliver them via an app to your fingertips,”
HGS RESEARCH HIGHLIGHT – Impacts of Coastal Shrimp Ponds on Saltwater Intrusion and Submarine Groundwater Discharge
This study investigates the potential impact that aquaculture can have on solute transport and saltwater intrusion in coastal settings. It is certainly an interesting read, and an interesting conceptual problem. Typically when we think of vertical saltwater intrusion it’s due to coastal inundation associated with temporary natural causes like storm surges. However, with shrimp pond aquaculture saline ponds are actually perched on top of agricultural soils, above a freshwater aquifer. In this study the authors have investigated several scenarios (varying pond water salinity, ponded water depth and farm/pond width) to see how it impacts a previously unrecognized/unstudied process contributing to groundwater salinization.
