Now if hydraulic conductivity ( " K " ) is spatially uniform and isotropic ( rather than a tensor ), it can be taken out of the spatial derivative, simplifying them to the Laplacian, this makes the equation

Hydraulic conductivity has units with dimensions of length per time ( e . g ., m / s, ft / day and ( gal / day ) / ft?); transmissivity then has units with dimensions of length squared per time.

This causes chemical reactions within the saprolite to leech certain minerals from the rock and if the hydraulic conductivity of that rock is high enough, the water can carry those minerals away, which can cause the infrastructure of that rock to collapse and erode.

Porosity can be proportional to hydraulic conductivity; for two similar sandy aquifers, the one with a higher porosity will typically have a higher hydraulic conductivity ( more open area for the flow of water ), but there are many complications to this relationship.

Darcy's law is a constitutive equation, empirically derived by Henry Darcy in 1856, which states that the amount of groundwater discharging through a given portion of aquifer is proportional to the cross-sectional area of flow, the hydraulic gradient, and the hydraulic conductivity.

In the fringe lands, the water table is shallow because the discharge capacity of the aquifer diminishes here for two reasons : ( 1 ) the hydraulic gradient reduces where the sloping alluvial fan reaches the flat desert area, and ( 2 ) the thickness and hydraulic conductivity of the aquifer diminishes.

The depth of the halocline is a function of several factors : climate and specifically how much meteoric water recharges the aquifer, hydraulic conductivity of the host rock, distribution and connectivity of existing cave systems and how effective these are at draining water to the coast, and the distance from the coast.

For example, if salinity figures of the groundwater are available and the value of hydraulic conductivity is uncertain, one assumes a range of conductivities and the selects that value of conductivity as " true " that yields salinity results close to the observed values, meaning that the groundwater flow as governed by the hydraulic conductivity is in agreemnent with the salinity conditions.
