Groundwater Storage, Porosity, and Specific Yield: Groundwater occupies the cracks and pore spaces between rocks and mineral grains below the land surface. In the saturated zone, essentially all of the pores are filled with water. If a volume of saturated aquifer material is completely dried, the water volume removed reflects the total porosity of the material, or the fraction of pore space within the total volume of solids plus open spaces. This number can be surprisingly large; some minerals and rock formations can have total porosities in excess of 50%. In the unsaturated, or vadose, zone there can be significant amounts of water present, but the voids are not completely filled (see appendix on saturated thickness).

However, some of the pore spaces may be too small or too poorly connected to permit the water they contain to flow out easily. The effective porosity can be thought of as the volume of pore space that will drain in a reasonable period of time under the influence of gravity. Effective porosity is always less than total porosity, sometimes (as in the case of clays) much less. "Good aquifers" tend to have values of effective porosity in the range of 10-30%, although examples of higher and lower values can be found. Figure 1 illustrates the relationship among the types of porosity and the volume of water in storage.

<span>The minor body that orbits the outside of the Neptune is the planet, Pluto. It slipped along the orbit of Neptune for it to be called as the ninth planet. However, this planet around 248 years to orbit along the sun, which is why it doesn't usually cross paths with Neptune.</span>

18. Which of the following is not correct about floodplains? they have recurrent problems with flooding the streams have natural
9966 [12]

Answer:

The statement that they are characterized by rapids and waterfalls is incorrect about floodplains.

Explanation:

All other points mentioned holds for flood plains:

  • Most of the floodplains are low lying areas
  • They are generally, the land areas which are adjacent to streams and rivers
  • They are subjected to repeated influx or flooding.
  • They can be simply characterized by a relatively smooth land area on whose boundary lies water stream or river which overflows or results in flooding at the time when water is high.
