Runoff formation in a tile-drained agricultural basin of the Harz Mountain Foreland, Northern Germany
hydrograph separation hydrological tracers isotopes dyes groundwater drain sampler
2015/2/4
By taking two different tile-drained agricultural basins with porous aquifers in the lowlands of northern Germany as examples, it is demonstrated with an integrated study approach that this type of ba...
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...
Fracture Systems and Groundwater Flow in the København Limestone Formation
Fracture Systems Groundwater Flow Kø benhavn Limestone Formation
2009/10/23
In connection with large construction works in the Copenhagen and Oresund
area a large number of investigations were conducted on the Kobenhavn Limestone
Formation. By combining the different invest...
The formation mechanisms and regional characteristics of spring water temperature on the northern foot of Mt. Asama
Mt. Asama Spring water temperature Volcanic activity Wind-hole circulation Groundwater flow system
2009/7/14
It can be recognized that water temperature of springs distributed on the northern foot of Mt. Asama has remarkable regional variations. The purposes of this study are to discuss the various formation...
Formation of runoff at the hillslope scale during intense precipitation
hillslope scale intense precipitation
2009/5/7
On 60 m2 hillslope plots, at 18 mainly grassland locations in Switzerland rain was applied at rates of 50–100 mm/h for between 3 and 6 h. The generated flows were measured, including overland flow, ne...
Constructal theory of pattern formation
pattern formation turbulent flow structure natural phenomenon
2009/5/7
This review article shows that the occurrence of macroscopic flow configuration is a universal natural phenomenon that can be explained and predicted on the basis of a principle of physics (the constr...
Self-similar pattern formation and continuous mechanics of self-similar systems
crack growth formation starts isotropically oriented crack
2009/5/7
In many cases, the critical state of systems that reached the threshold is characterised by self-similar pattern formation. We produce an example of pattern formation of this kind – formation of self-...
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...
Pressure head distribution during unstable flow in relation to the formation and dissipation of fingers
fingered flow wetting front instability unsaturated flow
2009/3/17
Wetting front instability creates a shallow induction zone from which fingers emerge that rapidly transport water and solutes downwards. How the induction zone affects finger location and spacing is u...
