A floating siphon made up of concentric tubes is proposed as a reliable
and inexpensive device to discharge water from a rescrvoir tank at a constant
rate independent of the water level in the tank,...
An Evaluation of the Importance of Transmissivity,Head and Concentration Data for Contaminant Transport Modelling
Importance of Transmissivity Concentration Data Contaminant Transport Modelling

The 3 basic data types of contaminant hydrology are examined by stochastic
modelling of a groundwater contamination case. The stochastic transport model,
which is of the Monte Carlo type, uses a num...

Current theories for water flow in porous media are valid for scales much smaller than those at which problem of public interest manifest themselves. This provides a drive for upscaled flow equations...
Water flow pathways and the water balance within a head-water catchment containing a dambo：inferences drawn from hydrochemical investigations

Dambos, seasonally saturated wetlands, are widespread in headwater catchments in sub-Saharan Africa. It is widely believed that they play an important role in regional hydrology but, despite research ...
Pressure head distribution during unstable flow in relation to the formation and dissipation of fingers
fingered flow wetting front instability unsaturated flow

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...
