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.1 day ago
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.
Natural factors, such as topographic position and the mineral composition of underlying geology, act to produce basic physical and geochemical conditions in groundwater that are reflected in physical properties, such as pH, temperature, specific conductance, and alkalinity, and in chemical concentrations of dissolved …
Groundwater flows faster where the hydraulic gradient and/or hydraulic conductivity are larger. Groundwater flow velocities are much slower than surface water flow velocities, except in limestone karst formations, where groundwater flows through caves and large solution channels.
How does the movement of groundwater relate to hydraulic gradient and hydraulic conductivity? … groundwater flows more rapidly through sediments having greater permeability than through materials having lower permeability. this factor is known as hydraulic conductivity.
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.
Fluctuations in the water table level are caused by changes in precipitation between seasons and years. During late winter and spring, when snow melts and precipitation is high, the water table rises. … Irrigation of crops can also cause the water table to rise as excess water seeps into the ground.
In addition to topography, water tables are influenced by many factors, including geology, weather, ground cover, and land use. Geology is often responsible for how much water filters below the zone of saturation, making the water table easy to measure. Light, porous rocks can hold more water than heavy, dense rocks.
The natural factors that affect water level fluctuations include: precipitation, evaporation, runoff, groundwater, ice retardation, aquatic growth, meteorological disturbances, tides, crustal movements and meteorological disturbances.
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 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.
When ground water is continuously being pumped for irrigation in the southern part of the high plains, there is a rigorous reduction of ground water. This happens because the aquifer does not get recharged by rain water because evaporation rate is more than the precipitation rate.
What factors affect the flow direction of the water below the water table? Groundwater flows from regions of recharge to those of discharge, driven by gravity and water pressure. … Groundwater flow is very slow compared to currents in surface water, generally moving at less then one and one-half meters per day.
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.
What most likely caused the water to rise and erupt from the vent? The water was heated by magma or hot rocks.
Aquifers typically consist of gravel, sand, sandstone, or fractured rock such as limestone. These types of materials are permeable because they have large connected spaces that allow water to flow through. The spaces in a gravel aquifer are called pores. The spaces in a fractured rock aquifer are called fractures.
The amount of water needed depends on several factors including age, weight, activity, type of food, gender and climate.
Various factors responsible for the depletion of water table are: (i) Increased population: Demand of water has been increased by the increased population. … (iii) Lack of water conservation techniques: Main source of water on earth and for the underground water is rain.
The stream or river’s gradient, flow, and stream load are three factors that describe the movement of surface water.
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.
Groundwater is dynamic natural resources that can be recharge most during the rainy season by the rainwater for the rest of the year. Over withdrawal of groundwater causes decline in the water table due to the stress and distorting the aquifer and may also leadadverse surface and subsurface environmental effect .
In contrast, groundwater movement in a deep regional system generally flows laterally toward the direction of decreasing gradient. An artesian well must tap into ______. List the features layered in the cross section of a flowing artesian well from top to bottom. What is drawdown?
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.
This is most often caused by human activities, mainly from the overuse of groundwater, when the soil collapses, compacts, and drops. Excessive pumping in coastal areas can cause saltwater to move inland and upward, resulting in saltwater contamination of the water supply.
It could be rapid snowmelt, intense rainfall, earthquake shaking, volcanic eruption, storm waves, rapid-stream erosion, or human activities, such as grading a new road. Increased water content within the slope is the most common mass-wasting trigger.
An underground layer of rock which holds fresh water and allows water to percolate through it. … Groundwater is in direct contact with the atmosphere through the open pore spaces of the overlying soil or rock.
Groundwater pumping from the the High Plains Aquifer has led to long segments of rivers drying up and the collapse of large-stream fishes.
