Aerial photogrammetry to characterise and numerically model an ice jam in Southern Quebec
Hydrology Research, 2023 Collecting data on the dynamic breakup of a river's ice cover is a notoriously difficult task. However, such data are necessary to reconstruct the events leading to the formation of ice jams and calibrate numerical ice jam models.

Unsteady Ice Jam Processes [PDF]
, 1997 Abstract : Ice jams cause flooding in northern temperate climate areas, usually forming rapidly, often with little warning, constricting water flow and elevating water levels. Consequently, jam formation comprises highly unsteady processes: drifting ice pieces are brought to rest, accumulated ice shoves and thickens, and initial water depths and ...

Climate-driven Shifts in Quantity and Seasonality of River Discharge over the past 1000 Years from the Hydrographic Apex of North America [PDF]
, 2008 Runoff generated from high elevations is the primary source of freshwater for western North America, yet this critical resource is managed on the basis of short instrumental records that capture an insufficient range of climatic conditions. Here we probe

Temporal and spatial variations in maximum river discharge from a new Russian data set [PDF]
, 2007 Floods cause more damage in Russia than any other natural disaster, and future climate model projections suggest that the frequency and magnitude of extreme hydrological events will increase in Russia with climate change.

Ice Formations Monitoring and intervention on the rivers in Romania in January-February 2017 [PDF]
Aerul şi Apa: Componente ale Mediului, 2018 This article presents ice monitoring and intervention on the rivers in Romania in January-February, 2017. After a long period in January with very low temperatures, there were positive temperatures with significant rainfall in the first decade, causing ...

Ice-Cover and Jamming Effects on Inline Structures and Upstream Water Levels
, 2017 River ice cover is a reoccurring phenomenon in the Northern United States every year. Sheets and layers of ice result in a rise of water surface elevation and may lead to ice jams in a river.

Iceberg jam floods in Icelandic proglacial rivers: testing the self-organized criticality hypothesis [PDF]
, 2016 In this paper, we describe a fluvial marginal process associated with the formation of iceberg jams in Icelandic proglacial lakes. The floods triggered by the release of these iceberg jams have implications for the geomorphic evolution of the proglacial ...

Considerations on Recent Freezing Phenomena on Bistriţa and Bistricioara Rivers
Present Environment and Sustainable Development, 2014 It is highly important to have a better knowledge of river systems during the seasons when air temperature drops below freezing point if we consider the difficulties posed to hydrotechnical exploitations and the destruction caused by floods (as a result ...
