Fluctuations in the Waterlevel in Wells Due to Variations in Atmospheric Pressure
Fluctuations Waterlevel in Wells Variations Atmospheric Pressure
2009/10/29
Deviations from the classical theory of the barometric efficiency (Jacob 1940) is
shown in some examples. A model with a semipermeable bed overlyingthe aquifer
is proposed, and equations for the flo...
Lateral Mixing in Channels due to Secondary Currents
Lateral Mixing Channels Secondary Currents
2009/10/27
Different mechanisms generating secondary currents in channels are presented.
It is shown by an order-of-magnitude analysis that secondary currents
of magnitude 1 % of the downstream velocity are as...
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...
APPLICATION OF A NUMERICAL MODEL TO PREDICT FRESH WATER DEPTH IN ISLANDS DUE TO CLIMATE CHANGE：AGATTI ISLAND, INDIA
FRESH WATER DEPTH ISLANDS CLIMATE CHANGE AGATTI ISLAND
2009/10/19
Global warming could raise sea level by several tens of centimeters in the next fifty years, about one meter in the century, and several meters in the next few centuries by expanding ocean water, by m...
SENSITIVITY OF HYDROLOGICAL VARIABLES IN THE ARCTIC WATERSHED, COPPERMINE RIVER, NWT, CANADA DUE TO HYPOTHETICAL CLIMATE CHANGE
Coppermine River climate change Water balance ARCTIC WATERSHED
2009/10/12
The hydrological sensitivities to long-term climate change of the Coppermine River watershed in the Arctic region of Canada were analyzed using a watershed runoff model. This model describes an interd...
A STOCHASTIC MODEL FOR IDENTIFICATION OF TRENDS IN OBSERVED HYDROLOGICAL AND METEOROLOGICAL DATA DUE TO CLIMATE CHANGE IN WATERSHEDS
climate change STOCHASTIC MODEL natural processes
2009/10/12
The development of appropriate public policy responses to the impact of climate change on the overall ecosystem would require knowledge of future trends in the natural processes affecting the ecosyste...
Hydrological processes and water resources management in a dryland environment IV：Long-term groundwater level fluctuations due to variation in rainfall
Long-term groundwater level fluctuations rainfall dryland environment
2009/5/26
To evaluate the effects of variations in rainfall on groundwater, long-term rainfall records were used to simulate groundwater levels over the period 1953-96 at an experimental catchment in south-east...
Extent of partial ice cover due to carbon cycle feedback in a zonal energy balance model
climate carbon cycle zonal model earth system modelling
2009/3/12
A global carbon cycle is introduced into a zonally averaged energy balance climate model. The physical model components are similar to those of Budyko (1969) and Sellers (1969). The new carbon compone...
