How Does Groundwater Move?

Groundwater. It is stored in and can flow through layers known as aquifers) moves more slowly than water flowing down a river or stream. It moves mainly under gravity from areas of high groundwater levels or pressure to areas of low groundwater levels or pressure – in other words it flows downhill.May 27 2015

Does groundwater move down?

The groundwater slowly moves through the spaces and cracks between the soil particles on its journey to lower elevations. This movement of water underground is called groundwater flow.

What force moves groundwater?

gravity

In contrast to surface water groundwater is separated from the atmosphere and as a result it can be under considerable pressure. Therefore the potential energy that drives groundwater movement includes both pressure and gravity.

How does groundwater move quizlet?

How does ground water flow? Ground water flows downwards under the influence of gravity from higher areas of recharge to lower areas where it may be either stored in aquifers or discharged into streams. In ground water systems deeper = slower movement = longer residence time.

How does groundwater move in aquifers?

Groundwater is transported through aquifers because of two main reasons: gravity and pressure. In unconfined aquifers which we concentrate on because they are more likely to be contaminated water always flows from high points to low points because of gravity.

Does groundwater move rapidly?

Groundwater starts as precipitation just as surface water does and once water penetrates the ground it continues moving sometimes quickly and sometimes very slowly.

How does groundwater get into the ground?

Ground water can be obtained by drilling or digging wells. A well is usually a pipe in the ground that fills with ground water. This water can then be brought to the land surface by a pump. … These wells are drilled into an artesian aquifer which is sandwiched between two impermeable layers.

How does groundwater become surface water?

Groundwater and surface water are interconnected groundwater becomes surface water when it discharges to surface water bodies. Most streams keep flowing during the dry summer months because groundwater discharges into them from the zone of saturation – this flow is called baseflow.

What major factors control the movement of ground water?

The two most important forces controlling water movement in rock are gravity and molecular attraction. Gravity causes water to infiltrate until it reaches impermeable zones where it is diverted laterally. Gravity generates the flow of springs rivers and wells.

Where is groundwater and how does it move quizlet?

Groundwater is the water stored in the pore spaces of rocks and soils underground. It is a part of the water cycle and is naturally refilled by precipitation and runoff that infiltrate the soil. It can then be pumped to your house by a well and through pipes. You just studied 51 terms!

What is groundwater flow in geography?

Groundwater flow – the deeper movement of water through underlying permeable rock strata below the water table. … Infiltration – the downward movement of water into the soil surface. Interflow – water flowing downhill through permeable rock above the water table.

How does most groundwater move in the subsurface quizlet?

Pulled by gravity groundwater seeps from the surface slowly downward through aquifers in the earth’s subsurface and eventually discharges into lakes rivers and the coastal ocean. The potential energy that drives this flow at given location is called hydraulic head.

What is groundwater in water cycle?

Groundwater is a part of the natural water cycle (check out our interactive water cycle diagram). Some part of the precipitation that lands on the ground surface infiltrates into the subsurface. … Water in the saturated groundwater system moves slowly and may eventually discharge into streams lakes and oceans.

How fast does groundwater move?

A velocity of 1 foot per day or greater is a high rate of movement for ground water and ground-water velocities can be as low as 1 foot per year or 1 foot per decade. In contrast velocities of streamflow generally are measured in feet per second. A velocity of 1 foot per second equals about 16 miles per day.

Which way is the groundwater flowing?

General flow directions are determined from contour maps of the water table and potentiometric surface (Fig. 2.5) if available or from information on water levels boundaries and locations of recharge and discharge areas. If there is more than one aquifer present flow directions are shown for each aquifer (Fig.

How do you get groundwater?

How do we get groundwater? Water in aquifers may be brought to the surface naturally through a spring or can be discharged into lakes and streams. However most groundwater is brought to the surface by pumping it through a well (which draws the water like soda through a straw) that is drilled into the aquifer.

What affects groundwater?

Industrial discharges urban activities agriculture groundwater pumpage and disposal of waste all can affect groundwater quality. Contaminants from leaking fuel tanks or fuel or toxic chemical spills may enter the groundwater and contaminate the aquifer.

What affects groundwater flow?

Water will flow from areas with high energy to those with low energy. Recharge areas are at higher elevations where the water has high gravitational energy. … That is the energy that was lost to friction as the groundwater flowed from the top of the hill to the stream.

What factors influence groundwater?

The groundwater level at each monitoring site is generally influenced by certain parameters e.g. rainfall aquifer properties (transmissivity) geomorphology topographic elevation and slope land use/land cover proximity to surface water body proximity to drainage lines etc.

Where does groundwater reside quizlet?

Groundwater resides in subsurface pore spaces. -Pores are open spaces within any sediment or rock. -The total volume of open space is termed porosity.

How does water get into the groundwater reservoir quizlet?

Infiltrating water moves downward into the subsurface by perolating along cracks and through the conduits that connect pores. saturated zone- where water completely fill or saturates pore space.

Where does groundwater come from quizlet?

Most groundwater originates as meteoric water from precipitation in the form of rain or snow. Once the water hits the land water from the surface seeps into the ground. The water is able to move underground through the rock and soil due to connected pore spaces.

What is the movement of water through rocks called?

Water reaches the groundwater store via the processes of infiltration and percolation . During these processes some water will be stored in the soil and rock. The amount of water stored will vary depending on the porosity of the soil and on the permeability of the rock.

How water moves through a drainage basin?

Precipitation – An input where water is introduced to the drainage basin system. … Throughflow – Water moves downhill through the soil. Groundwater flow – Water moving slowly through the soil and porous rocks to move back towards the sea. Percolation – Water moving from the soil into the spaces (pores) in the rock.

What are the two roles does groundwater have in the water cycle?

From the time the earth was formed it has been endlessly circulating through the hydrologic cycle. Groundwater is an important part of this continuous cycle as water evaporates forms clouds and returns to earth as precipitation.

How does most groundwater move in the subsurface?

Water moves underground downward and sideways in great quantities due to gravity and pressure. Eventually it emerges back to the land surface into rivers and into the oceans to keep the water cycle going.

How groundwater creates caverns quizlet?

How does groundwater create caverns? Most caverns are made at or below the water table. Acidic groundwater finds lines of weakness in the rock and slowly dissolves it along those joints. Over much time enough rock is dissolved to create caverns.

What is groundwater and how does it relate to the water table quizlet?

What is groundwater and how does it relate to the water table? groundwater is water that occupies the zone of saturation within the ground. the water table is the upper limit of the groundwater.

What is groundwater short answer?

Groundwater is the water found underground in the cracks and spaces in soil sand and rock. It is stored in and moves slowly through geologic formations of soil sand and rocks called aquifers.

How does water flow through soil and rock?

Water will move laterally in the soil profile if there is enough pore space in that soil. This movement is aided by the capillary action of water in small spaces. The water will bind to the edges of the pores and slowly move laterally and even upward if the voids are small enough.

How do you draw groundwater flow lines?

What means groundwater?

Groundwater is water that exists underground in saturated zones beneath the land surface. The upper surface of the saturated zone is called the water table. … If groundwater flows naturally out of rock materials or if it can be removed by pumping (in useful amounts) the rock materials are called aquifers.

What are the sources of groundwater?

Groundwater sources are beneath the land surface and include springs and wells. As can be seen from the hydrologic cycle when rain falls to the ground some water flows along the land to streams or lakes some water evaporates into the atmosphere some is taken up by plants and some seeps into the ground.

How abundant is groundwater?

Ninety-eight percent of Earth’s available fresh water is groundwater. It is about 60 times as plentiful as the fresh water found in lakes and streams.
