The velocity of unstable large ice masses from hanging glaciers increases as a power-law function of time prior to failure. This characteristic acceleration presents a finite-time singularity at the t...
A Perturbation Based Model of Heat-Induced Suppression of River Ice
Perturbation Based Model Heat-Induced Suppression River Ice
2009/10/27
The study of the thermal response of ice covered streams to an effluent of high
temperature, or of fast moving water, has been of considerable interest to those
concerned with hydraulic systems, env...
Changes in the Flexural Strength of Ice under Radiation Decay
Flexural Strength Ice under Radiation Decay
2009/10/26
The strength of an ice cover significantly affects the timing and severity of
breakup on northern rivers. During the pre-breakup period, thermal and radiative
warming is known to significantly decre...
This paper describes the spatial and temporal variability of strength in a typical
river-ice cover during the pre-breakup period affected by radiation decay.
Strength was determined using the boreho...
Kinematic Model of River Ice Motion During Dynamic Breakup
Kinematic Model River Ice Motion Dynamic Breakup
2009/10/26
We begin a study of the dynamics of ice motion during river breakup by
formulating a kinematic model. Ice continuity equations are applied to relate
the speeds of a breaking front, a convergence fro...
Frost Heave due to Ice Lens Formation in Freezing Soils 2.Field Application
Frost Heave Ice Lens Formation Freezing Soils Field Application
2009/10/26
An operational model for estimation of frost heave in field where stratified soil
profile appears is presented. The model is developed from the research model
described in part B. Soil layers are fi...
Frost Heave due to Ice Lens Formation in Freezing Soils 1.Theory and Verification
Frost Heave Ice Lens Formation Freezing Soils Theory and Verification
2009/10/26
A frost heave model which simulates formation of ice lenses is developed for
saturated salt-free soils. Quasi-steady state heat and mass flow is considered.
Special attention is paid to the transmit...
Neural Networks in the Ice-Correction of Discharge Observations
Neural Networks Ice-Correction Discharge Observations
2009/10/23
We have applied three models, a neural network, a conceptual model and a combination
of these two, a hybrid model, to model thc backwatcr effect of ice in a
river. The neural network is a black-box ...
Investigation of Ice and Water Properties and Under-ice Light Fields in Fresh and Brackish Water Bodies
Water Properties Under-ice Light Fields Water Bodies
2009/10/22
Light transmission through ice and light conditions beneath ice have been investigated
in the mild winter of the year 2000 in eight Estonian lakes and in one
braclush water basin, Santala Bay in the...

On River Level Rising in Springtime as caused by Ice Jams.
Development of a river ice jam by a combined heat loss and hydraulic model
river ice jam heat loss hydraulic model
2009/5/6
The heat loss theory and the hydraulic theory for the analysis of the development of wide channel ice jams are discussed and shown. The heat loss theory has been used in Iceland for a long time, while...
