Comparisons of local infiltration-excess, overland flow and associated erosion behaviour with river behaviour at the catchment scale
Hydrologic modeling overland flow erosion catchment scale
2015/8/6
Modeling overland flow and erosional behaviour is a very important scientific task today to prevent environmental impacts from human activities as well as physical disasters such as floods and deserti...
Continuum deformation and stability analyses of a steep hillside slope under rainfall infiltration
Coupled formulation Rainfall infiltration Slope stability Stabilized finite elements Unsaturated soil
2015/7/1
Rainfall weakens an earth slope in a number of ways. It increases the degree of saturation of the soil, thereby breaking the bonds created by surface tension between the soil particles. When the volum...

Modeling overland flow and erosional behaviour is a very important scientific task today to prevent environmental impacts from human activities as well as physical disasters such as floods and deserti...
Reactive-infiltration instabilities in rocks. Fracture dissolution
Reactive-infiltration instabilities rocks Fracture dissolution Fluid Dynamics
2012/4/19
A reactive fluid dissolving the surface of a uniform fracture will trigger an instability in the dissolution front, leading to spontaneous formation of pronounced well-spaced channels in the surroundi...
Integration of an analytic element model in a stochastic analysis of infiltration into a complex unconfined aquifer system
analytic element model stochastic analysis complex unconfined aquifer system
2009/12/4
A hydrologic model based on the Analytic Elements Method (AEM) has been developed for a phreatic aquifer in the General Separations Area (GSA), of the Savannah River Site (SRS), South Carolina, USA. T...
HOW MUCH PRECIPITATION GOES TO INFILTRATION DURING A STORM PERIOD?
PRECIPITATION GOES INFILTRATION STORM PERIOD
2009/10/29
Based on a detailed investigation of factors influencing infiltration in a
drainage basin, functional relationships amongst the abstractions during a
storm period, storm characteristics and conditio...
Infiltration Rates of Rainwaters in Sri Lanka Measured by Using Tritium Tracer
Infiltration Rates Rainwaters Sri Lanka Tritium Tracer
2009/10/28
Tritium tracer, injected below the surface soil, is used to follow the movement
of soil moisture in the unsaturated zone at several geo-hydrologically different
sites in Sri Lanka. Depth profiles of...
A state model for infiltration based on a spatial discretization of partial
differential equations of vertical water movement in unsaturated homogeneous
soil is presented. A transformation of the sp...
A one-dimensional mathematical model is used to simulate the process of
snow-melt infiltration in unsaturated frozen silt. Hydraulic and thermal parameters
are mainly based on data given in the lite...
The infiltration of snow melt water on arable land influences both the water
storage and the nutrient budget. The infiltration rate during thawing was
assumed to depend on the ice content of the soi...
Representation of Infiltration in Adaptive Rainfall–Runoff Models
Representation of Infiltration Adaptive Rainfall–Runoff Models
2009/10/26
The reliability of the extended Time Compression Approximation (TCA),
commonly adopted in watershed models in order to represent the infiltration
associated with erratic rainfalls, is investigated. ...

De-icing chemicals (containing 1,2 propane diol and potassium acetate) used on
airports in winter time mix with snow and start infiltrating along the runways in
spring. The distribution of the chemi...
COMPARISON OF LOCAL INFILTRATION EXCESS, OVERLAND FLOW AND ASSOCIATED EROSION BEHAVIOR WITH RIVER BEHAVIOR AT THE CATCHMENT SCALE
Data Based Mechanistic OVERLAND FLOW LOCAL INFILTRATION EXCESS CATCHMENT SCALE
