What controls the rate of movement of groundwater?

Answer 1

The water table is affected by the amount of water going into it, and the amount of water taken out of it. The level in the water table is also affected to some degree by geology and what happens to the water that is "just sitting" in the water table. Some may be able to "escape" in some way through premeable layers or cracks in the geologic structure. Certainly earthquates and vulcanism can modify the manner in which the water is held in the water table. Cracks can be originated or propagated (from existing fractures) under different conditions.

Answer 2

Ground water moves at a varying speeds depending on the nature of the material through which it is moving. Just to cite a couple of examples, consider sand and clay. Gravity acts to draw water down fairly quickly through sand, but a packed layer of clay will prevent water from moving through it very quickly, and can in many cases block the penetration of water completely. A review of the underground geology in a given area is required to plot or make estimates of (model) the speed at which ground water will move through it.

Answer 3

Some of the factors that control the speed and movement of ground water include the soil topography and the type of the soil. Some rocks or soils are more permeable than others.

Answer 4

Climate (precipitation, temperature)

Vegetation (plants)

Parent material (geological/organic)

Organisms (soil microbes/fauna)

Relief (configuration of surface)

Answer 5

anything can affect soil erosion, chemicals, also types of fertilizers and the structure is it clay like or very rich soil, depends in area.

Answer 6

The velocity at which water moves depends on the hydraulic head of the water and on the permeability of the material that the water is moving through.

Answer 7

water

Cohesion of water molecules, osmotic potential, gravitation force and transpiration pull (in plants) etc.

Answer 8

precipitation (rain, snow, etc.), lag time (diff between rainfall and when the water level goes back to normal), seasons, water pumping

Answer 9

The two factors that determine the flow velocity of ground water are perembilty and the force of gravity pulling the water downward.

Answer 10

Five factors of soil formation: Parent material, climate, organisms, topography and time.
