Hydrological Processes in the Subsurface Investigated by Water Isotopes and Silica
rainfall to runoff response isotopes
2015/3/1
The hillslope rainfall-outflow interactions, groundwater fluxes, and hydrological balance were examined in the small mountainous headwater catchment Uhlířská, the jizera Mountains, the Czech Repu...
Subsurface Flow in a Shallow Soil Canadian Shield Watershed
Subsurface Flow Shallow Soil Shield Watershed
2009/10/26
Past studies in Canadian Shield headwater catchments have identified the importance
of subsurface flow mechanisms in generating storm runoff. Recent
work in the Muskoka-Haliburton region of south-ce...
EQUILIBRIA IN SUBSURFACE FLUIDS WITH LINEAR INTERACTION BETWEEN DECAY AND SORPTION
SUBSURFACE FLUIDS LINEAR INTERACTION SORPTION
2009/10/19
There are many situations in groundwater transport where sorption processes act at the same time.
Equilibria of components in a decay chain, which are known for a single phase system, may remain val...
DELINEATING THE SUBSURFACE：USING SURFACE GEOPHYSICS TO IDENTIFY GROUNDWATER FLOW PATHS IN A CARBONATE AQUIFER
GROUNDWATER FLOW PATHS CARBONATE AQUIFER
2009/10/12
This study examines stream loss in a small tributary of the Youghiogheny River known as Hoyes Run in Garrett County, Maryland. The stream bounds the pit of the Deep Creek limestone quarry, operated by...
Simulation and validation of concentrated subsurface lateral flow paths in an agricultural landscape
Simulation validation lateral flow paths agricultural landscape
2009/9/11
The importance of soil water flow paths to the transport of nutrients and contaminants has long been recognized. However, effective means of detecting concentrated subsurface flow paths in a large lan...
Use of soil moisture dynamics and patterns at different spatio-temporal scales for the investigation of subsurface flow processes
soil moisture dynamics subsurface flow processes
2009/7/22
Spatial patterns as well as temporal dynamics of soil moisture have a major influence on runoff generation. The investigation of these dynamics and patterns can thus yield valuable information on hydr...
Applied tracers for the observation of subsurface stormflow at the hillslope scale
subsurface stormflow hillslope scale
2009/7/22
Rainfall-runoff response in temperate humid headwater catchments is mainly controlled by hydrological processes at the hillslope scale. Applied tracer experiments with fluorescent dye and salt tracers...
Averaging hydraulic head, pressure head, and gravitational head in subsurface hydrology, and implications for averaged fluxes, and hydraulic conductivity
hydraulic head pressure head gravitational head subsurface hydrology
2009/7/22
Current theories for water flow in porous media are valid for scales much smaller than those at which problem of public interest manifest themselves. This provides a drive for upscaled flow equations...
Present state of study on subsurface temperature and contribution of hydrology on it
subsurface temperature groundwater flow ground surface temperature (GST) reconstruction of climate change geothermal heat pump system
2009/7/14
Subsurface thermal regime is affected not only by thermal conduction but also by advection owing to groundwater flow. The effect of thermal advection is especially large in shallow sedimentary layer w...

Modelling subsurface storm flow with the Representative Elementary Watershed (REW) approach：application to the Alzette River Basin
Alzette River Basin subsurface storm flow Representative Elementary Watershed
2009/5/15
A new domain, the macropore domain describing subsurface storm flow, has been introduced to the Representative Elementary Watershed (REW) approach. The mass balance equations have been reformulated an...
Vectors of subsurface stormflow in a layered hillslope during runoff initiation
subsurface stormflow layered hillslope runoff initiation
2009/5/13
The focus is the experimental assessment of in-situ flow vectors in a hillslope soil. We selected a 100 m2 trenched hillslope study site. During prescribed sprinkling an obliquely installed TDR wave-g...
Temporal variability of subsurface stormflow formation
Subsurface stormflow precipitation intensity
2009/4/28
Subsurface stormflow (SSF) can play a key role for the runoff generation at hillslopes. Quantifications of SSF suffer from the limited ability to predict how SSF is formed at a particular hillslope an...
Developing a three-dimensional coupled model of pipe-matrix subsurface flow
subsurface flow pipe-matrix
2009/4/13
Over the past two decades, many studies have reported the presence of soil pipes in hillslopes and their significant influence on rainfall-runoff processes. To analyze pipe flow mechanisms which have ...
