The effective porosity may equal, or be less than, the total porosity (n) of the sample (Table 1). Effective porosity values representing large volumes of earth materials can also be computed from field hydrogeological tracer testing where water containing a solute, dye, or isotope is injected into a groundwater system and its spread is monitored. b) contamination moves opposite to the direction of groundwater flow 6. attract more contaminants In a material that holds groundwater, porosity: a) controls the amount of water that can be sorted b) determines the compostion of the cement between grains and clasts c) does not depend on the size and shape of grains and clasts d) is constant from one type of material to another. a) metallic bond However, whether that groundwater is able to flow in significant quantities depends on the permeability.

Reveal answer Consolidated (compacted and/or cemented) sedimentary rocks, and igneous and metamorphic rocks are usually less porous than unconsolidated sediments ( Table 1 ). b.Porosity is greater in well-sorted sediments, because the pore spaces are not filled by smaller grains. The speed of flow in rocks is extremely slow in comparison with surface flow, even for rocks with high hydraulic conductivities. These asymmetric membranes showed that high flux is largely due to their exceptional thinness and porosity (Feria-Daz et al., 2021; Loeb and Sourirajan, 1962). a) the amount of precipitation on land A coarse soil has bigger particles than a fine soil, but it has less porosity, or overall pore space. d) cleavage The top level of this saturated zone is called ground water table.

Water can be held tighter in small pores than in large ones, so fine soils can hold more water than coarse soils. Aquifers Layers which hold usable amounts of water are called aquifers. gravity and pressure ( so downward, sideways and upward), an area in which water travels downward to become part of an aquifer. a) to dissolve half of the atoms in the lattice It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers. Lecture notes Dr. J.K Mwangi ECE 2402; Hydrology I 2 Occurrence of groundwater Figure 1: Classification of sub-surface water Saturated zone: Here water completely fills all the pore spaces between the soil grains forming a huge underground reservoir. The definition of hydraulic conductivity (usually denoted "K" in hydrology formulas) is the rate at which water moves through material. C. This dissolution widens cracks into caves or caverns.
