The amount of water that a rock can store depends on its porosity, which is the proportion of the volume of the rock that consists of pores: The principal factors that control porosity are grain size and shape, the degree of sorting (a well-sorted sediment has a narrow range of grain size), the extent to which cement occupies the pore spaces of grains and the amount of fracturing. 37.

Most simply, the aquifer's porosity and permeability (defined above) are variables that govern its hydraulic conductivity and storativity. in a material that holds groundwater, porosity, controls the amount of water that can be stored, Ability of rock or soil to allow water to flow through it, material that has low porosity and permeability so that it does not transmit water easily is called, main way surface water becomes ground water, water flows thru the unsaturated zone and into the saturated zone, groundwater velocity is most strongly influenced by, water table has a similar shape to topography, the well above the contaminate on the hill, a large body of permeable, saturated material thru which groundwater can flow well enough to yield sufficient water to wells, bottom of the lens of fresh water will rise, causing the well to draw in salt water, plume of contamination spreads out (becomes wider) away from the source of contamination, because of diffusion of the contamination and mixing of contaminated and uncontaminated water, 1. cone of depression Permeability takes this pore space and connects the voids together so that water can pass through. Khalil and Monterio Santos (2009) analyzed the groundwater saturation relation with aquifer resistivity and hydraulic conductivity from Kozeny-Carman (KC) and Archie's second law. b) rapids a) spring water CAS .
