Reliability is an integral part of all decisions regarding water distribution system layout, design, operation and maintenance. Providing reliability for water distribution systems is complicated due ...
Optimal design of storm water inlets for highway drainage
Optimal design storm water inlets highway drainage
font style='font-size:12px;'>
2009/12/4
A new methodology and computational model are developed for direct evaluation of an optimal storm water inlet design. The optimal design is defined as the least-cost combination of inlet types, sizes ...

water fingering phenomena magnetic resonance imaging multifractal theory
font style='font-size:12px;'>
2009/10/30
The study of water movement in soils is of fundamental importance in hydrologic science. It is generally accepted that in most soils, water and solutes flow through unsaturated zones via preferential ...
AN ESTIMATION OF EVAPOTRANSPIRATION BY MEANS OF THE WATER BALANCE OF A SOIL COLUMN
ESTIMATION OF EVAPOTRANSPIRATION MEANS OF THE WATER BALANCE SOIL COLUMN
font style='font-size:12px;'>
2009/10/30
In this paper water-balance studies of a soil column at an observation site
at Ulvsunda, Stockholm, are reported. The change of the water storage in
the soil was obtained from soil moisture measurem...
MECHANISM OF GROUND WATER RESERVOIRS
MECHANISM GROUND WATER RESERVOIRS
font style='font-size:12px;'>
2009/10/29
The article deals with unsteady ground water flow in an aquifer of limited
horizontal extent. The changes in storage are taken to be dependent
on a storage coefficient S, and flow rates are taken to...
A STOCHASTIC MODEL DESCRIBING THE WATER MOTION IN A RIVER
STOCHASTIC MODEL WATER MOTION
font style='font-size:12px;'>
2009/10/29
In this paper a mathematical model for the movement of water particles
in a river is constructed.
Using the model it will be possible to find an analytic expression for the
distribution function F(...
