Numerical Simulation of Ice Fractures Process of the Yellow River Based on Disk Specimen

open access: yesCrystals, 2020
To study the influence of the changes in crystals on a micro scale as well as their effect on the macro mechanical properties of river ice and to mitigate the limitation of the objective conditions in a physical examination of river ice, it is necessary ...

Climate-driven Shifts in Quantity and Seasonality of River Discharge over the past 1000 Years from the Hydrographic Apex of North America [PDF]

open access: yes, 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

Monitoring the Variation in Ice-Cover Characteristics of the Slave River, Canada Using RADARSAT-2 Data—A Case Study

open access: yesRemote Sensing, 2015
The winter regime of river-ice covers in high northern latitude regions is often a determining factor in the management of water resources, conservation of aquatic ecosystems and preservation of traditional and cultural lifestyles of local peoples.

Long term trend of chemical oxygen demand in Saroma-ko Lagoon, Japan; possible effects of climatic warming [PDF]

open access: yes, 2008
A trend of shortening duration of ice coverage has been reported in many rivers, ponds and lakes around the world due to climatic warming. The shortening will have much influence on organic production due to the greater supply of light intensity and ...

Simulation Analysis of Three-Point Bending Fracture Process of Yellow River Ice

open access: yesCrystals
During the ice flood period of the Yellow River, the fracture and destruction of river ice can easily lead to the formation of ice jams and ice dams in the curved and narrow reaches. However, the occurrence and development mechanism of river ice fracture

Challenges in modelling river flow and ice regime on the Ningxia–Inner Mongolia reach of the Yellow River, China [PDF]

open access: yesHydrology and Earth System Sciences, 2014
During winter the Yellow River in China is frequently subjected to ice flood disasters. Possible dike breaking due to ice floods poses a serious threat to the part of the region located along the river, in particular the Ning–Meng reach (including ...

Ice-Cover and Jamming Effects on Inline Structures and Upstream Water Levels

open access: yes, 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.

Evidence for suppressed mid-Holocene northeastern Australian monsoon variability from coral luminescence [PDF]

open access: yes, 2014
Summer monsoon rainfall in northeastern (NE) Australia exhibits substantial interannual variability resulting in highly variable river flows. The occurrence and magnitude of these seasonal river flows are reliably recorded in modern inshore corals as ...

Monitoring River Ice in the Northern Section of Yellow River Using Sentinel-1/2 Images

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
River ice monitoring plays a critical role in ice flood mitigation and control, hydrological research, and water resource regulation. The northern section of the Yellow River (NSYR) experiences the most frequent water level fluctuations due to river ice.

Comprehensive two-dimensional river ice model based on boundary-fitted coordinate transformation method

open access: yesWater Science and Engineering, 2014
River ice is a natural phenomenon in cold regions, influenced by meteorology, geomorphology, and hydraulic conditions. River ice processes involve complex interactions between hydrodynamic, mechanical, and thermal processes, and they are also influenced ...
