What Factors Cause Water To Follow The Paths Shown In The Above Diagram?


What Factors Cause Water To Follow The Paths Shown In The Above Diagram??

What factors cause water to follow the paths shown in the above diagram? Water that enters the groundwater at the recharge areas moves downward due to gravity and then loops upward to the discharge areas due to water pressure.

What two factors determine how easily water can move through the ground?

What two factors determine how easily water can move through underground materials? The size of the pores underground rock material has and if the pores are connected. Define permeable? Rock materials that are permeable have tiny connected air spaces that allow water to seep through.

Why does the water table Follow topography?

Water tables often (but not always) follow the topography or upward and downward tilts of the land above them. Sometimes a water table runs intersects with the land surface. … In addition to topography water tables are influenced by many factors including geology weather ground cover and land use.

What factors affect the rate of groundwater flow?

Topography and geology are the dominant factors controlling groundwater flow. Storativity describes the property of an aquifer to store water. Hydraulic conductivity is measured by performing a pumping test i.e. by pumping one well and observing the changes in hydraulic head in neighboring wells.

How does the movement of groundwater relate to hydraulic gradient and hydraulic conductivity?

groundwater moves more quickly down steeper slopes than down shallow slopes. for this reason the water table is known as the hydraulic gradient. groundwater flows more rapidly through sediments having greater permeability than through materials having lower permeability. this factor is known as hydraulic conductivity.

What factors influence the movement of water underground?

Thus the groundwater flow around the cavern is influenced by not only major natural factors such as the distribution of faults and joints topographical features and soil properties but by artificial factors such as water curtains and caverns.

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.

What factors affect the level of the water table?

Water tables are affected by several factors:
  • Seasonal rainfall and droughts.
  • Salt contamination.
  • Nitrates and phosphates from fertilizers.
  • Bacteria from barnyard runoff or septic systems.
  • Pesticides and fertilizers.

What is above the water table?

The soil surface above the water table is called the unsaturated zone where both oxygen and water fill the spaces between sediments. The unsaturated zone is also called the zone of aeration due to the presence of oxygen in the soil.

How does topography affect water?

Topographic shape is a watershed attribute thought to influence the flow path followed by water as it traverses a catchment. … These results suggest that during high flow periods both the average stream acidity and the magnitude of fluctuations in H+ are conditioned by the topographic shape of the catchment.

What causes groundwater to flow?

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.

What is a water table and what factors affect its level what factors affect the flow direction of the water below the water table?

What factors affect the flow direction of the water below the water table? Water table- the horizon that separates the unsaturated zone above from the saturated zone below. It is affected by-the water supply from above rainfall and location. Flow direction of water is affected by gravity and pressure.

What are the factors of ground water?

From the table we can conclude that the most common factor affecting ground water is seawater intrusion and is followed by coal-ash. The remaining factors following respectively are industrial storage tanks arsenic and agriculture.

What problem is caused by pumping groundwater for irrigation in the Southern High Plains quizlet?

What problem is caused by pumping groundwater for irrigation in the Southern High Plain? A low precipitation rate and a high evaporation rate allow little water to recharge the aquifer.

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.

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 are the three factors that influence the composition of ground water?

A principal component analysis (PCA) indicated that the three factors affecting groundwater hydrochemistry in the study area are domestic sewage and fertilizer water–rock interactions and industrial wastewater.

What is the biggest factor in determining the water movement of an aquifer?

The ability to travel through the rock or soil is known as permeability. The permeability and porosity measurements in rock and/or soil can determine the amount of water that can flow through that particular medium. A “high” permeability and porosity value means that the water can travel quickly.

What major factors control the movement of groundwater quizlet?

Groundwater flow rates are controlled by the permeability of the aquifer through which the water is flowing and by the local hydraulic gradient (the drop in hydraulic head per unit distance equal to the slope of the water table for unconfined aquifers).

What causes the water table to fall?

Heavy rains or melting snow may cause the water table to rise or heavy pumping of groundwater supplies may cause the water table to fall. … In other areas groundwater is polluted by human activities. Water in aquifers is brought to the surface naturally through a spring or can be discharged into lakes and streams.

What do you understand by water table name the factors that affect the water table Class 7?

If there is more rainfall and more rainwater seeps into ground the water table rises. And if excessive amount of groundwater is withdrawn for irrigation and industries then the water table falls. The water found below the water table is called groundwater.

Which side effect is directly caused by draining the groundwater from a region?

The land these buildings sit on has fallen and compacted because large amounts of groundwater have been withdrawn from the aquifers below ground. Land subsidence is a human-induced event.

What is the upper surface of water in a confined aquifer called?

The upper surface of water in a confined aquifer is called piezometric surface. … Such wells are called Artesian wells or flowing wells and the type of groundwater obtained from them which often needs no pumping as Artesian Water.

What is the effect of rainfall on water table?

Usually water-tables become shallower during autumn and winter when rainfall exceeds evapotranspiration reaching their maximum depths during the summer (Degioanni et al. 2002 INTA-SAGyRR 1987).

How does topography cause flooding?

The lower the site elevation the smaller the site relief the lower the site roughness and higher the likelihood that the site will experience urban flooding. Surface roughness is the topographical influencing factor with the greatest influence on urban flooding.

How does topography affect water erosion?

Topography or lay of the land is an important variable in water erosion. Steep slopes have high runoff water velocity. … This increases its erosive energy (remember that erosive energy of runoff is a function of runoff velocity and volume).

What affects the availability of water?

Access to a fresh water supply is affected by the following factors: Climate – low levels of rainfall and high temperatures lead to water deficits . … Water surpluses are common where rainfall is high and temperatures are lower. Geology – rainfall flows down to the rocks beneath the ground.

Why do water levels in wells rise and fall?

It all depends on how fast the aquifer that the well uses is resaturated with water from the surface or from the area surrounding it (recharge). … The characteristics of the rock that make up the aquifer come into play here especially how permeable and porous the aquifer is.

In what ways does the water table mimic topography quizlet?

How does it relate to the topography of the land surface? Water table elevation typically mimics the topography but it more higher under hills and lower under valleys. What effect does the amount of precipitation have on the level of water table? in a wet period the water table rises a dry period causes it to fall.

What are the factors which control the occurrence and distribution of ground water?

Remote sensing and GIS tools have broadly helped hydrogeologists to delineate the groundwater prospective zones for watershed development and management. The origin movement and existence of groundwater depends on several factors such as slope drainage density land use geology lineament density and geomorphology.

What problems are associated with pumping groundwater in certain parts of the High Plains region?

Groundwater pumping from the the High Plains Aquifer has led to long segments of rivers drying up and the collapse of large-stream fishes.

Why might the ground subside after groundwater is pumped to the surface?

Why might the ground subside after groundwater is pumped to the surface? As water is withdrawn the water pressure drops and the sediment is left to support the weight on top of it. As a result the sediment packs more closely together causing the ground to subside.

What significant problem might arise when groundwater is heavily pumped along a sea coast?

What significant problem might arise when groundwater is heavily pumped at a coastal site? If the groundwater withdrawal exceeds recharge the saltwater will become high enough to be drawn into the wells.

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.
