Movement and leaching of residual nitrogen in soil has been studied in some
details in a lysimeter experiment. Profile measurements of soil water and of
nitrogen concentration in addition to measure...

The Movement of a Continuously Growing Body of Oil on the Ground Water Table
Continuously Growing Body Oil Ground Water Table
2009/10/28
Approximative formulas for the movement of a continuously growing body of
oil on the ground-water table are presented and illustrated. The approximations
are many, but the formulas are believed to p...
The relation between rain movement and areal reduction of rain intensity is
investigated. An approach for calculating areal reduction factors from point
hyetographs and storm speed is suggested. Ver...
A kinematic approach is applied to compute moisture flux and particle velocities
in the unsaturated zone. The computations are compared with observations
of tracer marked meltwater particles. Ground...
Influence of Rainfall Movement on Peak Discharge in Urban Sewers
Rainfall Movement Peak Discharge Urban Sewers
2009/10/26
Calculations have been made in order to evaluate the effect of rainfall movement
on peak discharge. The 25 extreme events have been selected from a long
historical rain series from a single rain gau...
A Theoretical Model of Thermal Bar Movement in a Circular Lake
Theoretical Model Thermal Bar Movement Circular Lake
2009/10/26
The present paper concentrates on the movement of the spring thermal bar
with time, and a simple theoretical model is derived for the case of an axisymmetric
circular lake. The lake is considered to...
SEDIMENT FLOW WITH HIGH CONCENTRATION AND ITS MOVEMENT BEHAVIOR
SEDIMENT FLOW HIGH CONCENTRATION MOVEMENT BEHAVIOR
2009/10/19
In the Yellow River, the annual average sediment discharge and the annual average sediment concentration are the highest in the world. The measured maximum concentration approaches 1600 kg/m3 in its t...
Scientists give insight into movement of molecules

2009/10/10
Scientists at the University of Sheffield have made an exciting breakthrough in the control of the movement of single molecules. The findings represent a significant step forward in the field of molec...
Interpacket diffusion in SAMP model for water and solute movement in unsaturated soil
unsaturated soil SAMP model water solute movement
2009/6/8
SAMP (subsystems and moving packets) is a recently developed method for modelling preferential flow and solute movement in porous media, and for determining the fate of "new" and "old" water and solu...
Simulation of water movement and isoproturon behaviour in a heavy clay soil using the MACRO model
water movement heavy clay soil isoproturon behaviour
2009/6/8
In this paper, the dual-porosity MACRO model has been used to investigate methods of reducing leaching of isoproturon from a structured heavy clay soil. The MACRO model was applied to a pesticide leac...
The wave-induced movement of oil lenses and other floats was studied by using mechanically generated gravity waves in a water tank. The measured surface drift velocities were in all cases higher than ...
The Essence of the “Yahagi River Method,” as Seen in the Yahagi River Basin Environmental Movement
River Law environmental movement
2009/4/1
Today there is a heightened awareness of our environment, rendering an exclusive focus on development no longer acceptable. People have started to demand development that is appropriate to each locali...
Distribution and Movement of Gulf Stream Rings
David Y. Lai
The distribution, number and movement of cyclonic Gulf Stream rings were estimated from an analysis of 50 000 temperature records ...
