Quasi-three-dimensional numerical model for flow through flexible,rigid,submerged and non-submerged vegetation
Quasi-three-dimensional numerical model non-submerged vegetation
font style='font-size:12px;'>
2009/12/4
The effects of the resistance caused by vegetation on flow velocity and water depth has become a major interest for ecologists and those who deal with river restoration projects. Some numerical and ex...
Particle dispersion processes in two-dimensional turbulence:a comparison with 2-D kinematic simulation
Particle dispersion processes two-dimensional turbulence 2-D kinematic simulation
font style='font-size:12px;'>
2009/11/2
We study numerically the comparison between Lagrangian experiments on turbulent particle dispersion in 2-D turbulent flows performed, on the one hand, on the basis of direct numerical simulations (DNS...
THREE-DIMENSIONAL STABILITY ANALYSIS OF OPEN CHANNEL FLOW OVER AN ERODIBLE BED
THREE-DIMENSIONAL STABILITY ANALYSIS OPEN CHANNEL FLOW ERODIBLE BED
font style='font-size:12px;'>
2009/10/29
The formation oP ripples and dunes (lower range bed waves) is assumed to
be related to the transport of sediment as bed load. From the present
theory it is concluded that the formation of the upper ...
A One-Dimensional Numerical Model for Temperature Studies in Lakes
One-Dimensional Numerical Model Temperature Studies
font style='font-size:12px;'>
2009/10/29
Most hydro-electric schemes change the seasonal variation of river discharge. As a result of this the temperature in lakes downstream of a hydro-electric plant will be changed. The numerical model des...
Longitudinal Dispersion in a Stream Calculated by One Dimensional Numerical Model
Longitudinal Dispersion Dimensional Numerical Model
font style='font-size:12px;'>
2009/10/28
A one-dimensional numerical model was used to simulate water stage and
dispersion of matter in a stream. The calculated results show quite good
agreement with field measurements.
Studies concerning...
Developing a three-dimensional coupled model of pipe-matrix subsurface flow
subsurface flow pipe-matrix
font style='font-size:12px;'>
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 ...
A quasi three dimensional model of water flow in the subsurface of Milano (Italy): the stationary flow
subsurface of Milano dimensional model
font style='font-size:12px;'>
2009/3/24
A quasi three-dimensional model is developed to simulate the behaviour of the aquifer system which is the resource of drinkable water for the town of Milano (Italy). Non continuous semipermeable layer...
A quasi-three-dimensional model for predicting rainfall-runoff processes in a forested catchment in Southern Finland
rainfall-runoff forested catchment
font style='font-size:12px;'>
2009/3/24
Runoff generation in a forested catchment (0.18 km2) was simulated using a quasi-three-dimensional rainfall-runoff model. The model was formulated over a finite grid where water movement was assumed t...
Oxygen dynamics in the rhizosphere of Zostera marina: A two-dimensional planar optode study
Zostera Oxygen dynamics
font style='font-size:12px;'>
2014/5/4
The oxygen dynamics in the rhizosphere of Zostera marina was studied by use of planar optodes. Oxygen leakage to the rhizosphere was restricted to the root tip and extended only up to ~8 mm up along t...
