2024年12月7日 · Ice jamming is the primary mechanism that can generate overland flooding and recharge the isolated basins of the Peace–Athabasca Delta (PAD), a valuable ecosystem of international importance and the ancient homeland of the Indigenous Peoples of the region.

Ice breakup occurs in early spring each year. As temperatures rise, snowmelt and rainfall increase flow into the watershed, raising water levels and increasing pressure on weakened ice. These conditions cause large segments of ice to break apart and flow down stream.

2021年12月21日 · Spring ice-run floods without ice jams can recharge portions of the PAD including perched basins. I describe two water management approaches that would recharge large areas. Ecosystem complexity and cognitive biases hamper greater understanding of the dynamics of this globally significant ecosystem. ”It doesn’t matter how beautiful your theory is.

4 天之前 · Break up ice jams in the spring are more common on north-flowing rivers, which account for approximately 60% of Canada’s river drainage, such as the Peace and Athabasca Rivers. When the southern part of the river basin experiences warmer temperatures, the early snowmelt runoff flows north, encountering stronger and less deteriorated ice as it ...

2024年6月1日 · Late summer flow reduction (8–25 %) can have critical implications, given the rising water demand in the basin. The study identified eleven key indicators encapsulating the basin's flow regime variability range. It was found that ice cover, its break-up, and spring freshet significantly influence the flow regime of the basin.

2019年9月1日 · Major ice jams forming in the lower reaches of Peace River during the spring breakup of the ice cover have been identified as the main agents of flooding and replenishment of the perched basins of Peace–Athabasca Delta, one of the world's largest inland freshwater deltas.

2021年6月1日 · Major ice jams forming in lower reaches of the Peace River during spring breakup have been identified as the main agents of flooding and replenishment of perched basins of the Peace–Athabasca Delta, one of the world's largest inland freshwater deltas that supports a dynamic and valuable ecosystem.

2024年4月16日 · Breakup is underway on the Athabasca River between the Pembina River and Crooked Rapids upstream of Fort McMurray. Larger reaches of open channel are clearing, accumulating into ice jams. Most ice jams were less than 5 kilometres long.
