Estimation of aquifer hydraulic characteristics from electrical sounding data: the case of middle Imo River basin aquifers, south- eastern Nigeria
Aquifer hydraulic characteristics Dar - Zarrouk parameters
2015/8/11
We have used the concept of Da - Zarrouk parameters (transverse unit resistance (R) and longitudinal conductance (C)) in porous media to determine aquifer hydraulic characteristics within the middle I...

We have used the concept of Da - Zarrouk parameters (transverse unit resistance (R) and longitudinal conductance (C)) in porous media to determine aquifer hydraulic characteristics within the middle I...
GIS Integration of Remote Sensing and Electrical Sounding Data for Hydrogeological Exploration
Groundwater GIS Remote Sensing
2014/11/12
Interpretation of hydrogeological data frequently involves assimilating information from many
sites each with a unique geographical location. Interpretation of these data requires that the
spatial l...
Diurnal Variations in Electrical Conductivity of Water in a Small Stream
Diurnal Variations Electrical Conductivity of Water Small Stream
2009/10/28
Diurnal fluctuations in electrical conductivity of water have been observed in
a small streBm draining a basin 12 km2 in size. An attempt to explain the cause
of these variations is presented. The t...
MODELING OF CHEMICAL AND ELECTRICAL FLOWS IN LOW PERMEABILITY SOILS UNDER ELECTRICAL GRADIENT
ELECTRICAL FLOWS LOW PERMEABILITY SOILS CHEMICAL ELECTRICAL GRADIENT
2009/10/19
If an electrical gradient is imposed on wet fine-grained soil, contaminant transport occurs by a complex phenomenon called electrokinetics. Even though electrokinetics has been proven to be feasible i...
Continuous pH, electrical conductivity and temperature measurement at Plynlimon：towards an integrated, reliable and low maintenance instrument system
Water quality Continuous pH temperature measurement electrical conductivity
2009/6/8
Water quality data for the Nant Tanilwyth stream, Plynlimon (an acidic upland stream, the waters of which are of such low ionic strength that measurement is difficult), has been recorded using a new i...
Electrical Imaging of Saline Tracer Migration for the Investigation of Unsaturated Zone Transport Mechanisms
Saline Tracer Migration Unsaturated Zone Transport Mechanisms
2009/6/8
Better understanding of field-scale unsaturated zone transport mechanisms is required if the fate of contaminants released at the surface is to be predicted accurately. Interpretation of results from...
Extension of the measurement range of electrical conductivity by time-domain reflectometry (TDR)
electrical conductivity time-domain reflectometry
2009/6/8
The electrical conductivity (EC) of a medium invaded by TDR sensors can be estimated from the impedance of a TDR reflectogram. Four categories of sensor were tested in salt solutions and the impedance...
Modelling a river catchment using an electrical circuit analogue
river catchment electrical circuit analogue
2009/5/27
An electrical circuit analogue of a river catchment is described from which is derived an hydrological model of river flow called the River Electrical Water Analogue Research and Development (REWARD) ...
