Article
Waste stabilization ponds (WSPs) rely on natural processes to improve water quality. WSPs require less capital or operational resources than traditional treatment and are commonly used in rural communities or for secondary disinfection. Typically, WSPs designs use empirical equations without three-dimensional (3D) circulation, thermal stratificatio...
Article
Waste stabilization ponds (WSPs) are a common wastewater treatment approach throughout the world. Typically, WSPs are designed with the aid of empirical equations that may not incorporate complex hydrodynamics. Whereas numerical models have been presented as an alternative, they have been limited to two dimensions or lacked validation. In the prese...

During extreme storms, both wind‐driven changes in water levels and intense precipitation can contribute to flooding. Particularly on low‐lying coastal plains, storm‐driven flooding can cover large areas, resulting in major damage. To investigate the roles of rainfall and storm surge on coastal flooding, a coupled flow‐wave model (Delft3D‐SWAN) tha...

Pamlico Sound, a large back-barrier estuary in North Carolina, is under threat of climate change due to increased storm activity and sea-level rise. The response of this system is investigated by considering what has already happened during changes in sea-level over the late Holocene epoch. The hydrodynamic changes that occurred in response to geom...

Hyporheic flow, the flow of water through the permeable material immediately surrounding a river, is important for nutrient cycling, dissolved oxygen transport, and contaminant transport. In addition, there is recent concern regarding the role of hyporheic flow on the contamination of rivers following oil spills. To better understand hyporheic flow...
Conference Paper
Investigation of hydrodynamic patterns within a wastewater stabilization pond to improve treatment modeling
Conference Paper
This paper originates from a study to evaluate the long term effect of river sediment contamination by oil spills, recently initiated at Queen’s University. The paper presents results of the first phase of the study, dedi-cated to exploring a suitable computational framework for the simulation of hyporheic flow through gravel bars. Results of a ful...
