Howley, Rhodri

Northern rivers are affected by river ice processes for a significant portion of the year. This poses many challenges and opportunities to river ice engineers and geoscientists. Since 2009, several researchers have conducted a variety of river ice studies on the North Saskatchewan River through...

River ice breakup has great implications to the environment, ecology and economy. A mechanical breakup tends to occur if fast-rising river flow instigates ice movements. The breaking front, the interface between moving and stationary ice, can sometimes travel hundreds of kilometres, resulting in...

Frazil ice particles and flocs can adhere to underwater structures causing blockage to water intakes and large accumulation of frazil ice in the channel may cause flooding and property damage. After frazil floc rises to the water surface the resulting surface ice profoundly impacts river...

Both the observed and projected temperature in Canada increase faster than the global temperature, which has extensive implications on snow and river ice breakup regime, and then can greatly affect the timing and magnitude of snow and ice affected spring streamflow. This research is to expand our...

The Town of Hay River, located in the North West Territories, Canada, is vulnerable to ice jam flooding occurring in the adjacent Hay River delta. The most extreme flooding events have occurred when ice jams in the channels of the delta were pushed downstream towards the mouth of Great Slave...

Rivers in cold regions experience ice conditions for a significant part of the year. River ice can cause ice jam flooding, impact hydropower generation operations, and affect a river’s ecological and morphological conditions. Many ice processes are highly dynamic and are affected by...

Geobags, or geotextile sand filled containers, have emerged as a cost-effective solution to providing large scale erosion protection for riverbanks and riverbeds in Bangladesh, China, and India. Geobags are currently designed using a formula intended for rock-based riprap that does not consider...

Nafziger, Jennifer L.

River ice processes are among the most important subjects of study for hydrotechnical engineers in cold regions. This is because extremes of both minimum flow (impacting fish habitat and the concentration and transport of pollutants) and maximum water levels (impacting channel geomorphology and...
