Document Summary
What rock types make good aquifers and why, two major types of sedimentary rocks that can hold water for aquifers: i. Limestone and sandstone: this is because they porous, well-sorted and less cemented, where is our groundwater? i, where there is porous rocks (where there"s space for it) Shallow, below the surface: sedimentary rocks, what law describes groundwater flow speed? what are the factors that control flow, they may erode or be moved by the water to make space, darcy"s law: i. Q = a[k( h l: q = volume of water, a = cross section area of flow, k = permeability of aquifer (hydraulic conductivity, h = vertical drop l = flow distance. = slope of water table: what is karst topography? how does it form, definition, mainly made out of limestone (or other carbonates) that has eroded from.
