When groundwater discharges into surface water, they flow together. Streams and rivers flow down the valley of the watershed until they join larger rivers and, eventually, reach the ocean. Thus, groundwater typically flows toward a stream, while the stream flows toward the ocean.Surface water seeps into the ground and recharges the underlying aquifer—groundwater discharges to the surface and supplies the stream with baseflow. USGS Integrated Watershed Studies assess these exchanges and their effect on surface-water and groundwater quality and quantity.A watershed includes the network of streams that drains that surface land area, and the groundwater and aquifers located underground that contribute water to those streams.
What is the relationship between groundwater and surface water?
Surface water seeps into the ground and recharges the underlying aquifer—groundwater discharges to the surface and supplies the stream with baseflow. USGS Integrated Watershed Studies assess these exchanges and their effect on surface-water and groundwater quality and quantity.
Does a watershed include groundwater and surface water?
A watershed includes the network of streams that drains that surface land area, and the groundwater and aquifers located underground that contribute water to those streams.

What is the relationship between surface water and groundwater quizlet?
Surface water is all water above the land, including lakes, rivers, streams, ponds, floodwater, and runoff. Ground water is the water beneath the surface of the earth, consisting largely of surface water that has seeped down: the source of water in springs and wells.
What is the relation of the surface of the water in the stream to the water table?
For a stream to gain water, the elevation of the water table in the vicinity of the stream must be higher than the streamwater surface. For a stream to lose water to groundwater, the water table must be below the elevation of the stream-water surface in the vicinity of the stream.
Are groundwater and surface water the same?
Surface water includes any freshwater that’s sent into wetlands, stream systems, and lakes. On the other hand, groundwater exists in subterranean aquifers that are situated underground. Most groundwater is obtained from snowmelt and rainfall that gets into the bedrock via the surrounding soil.
How are surface water and groundwater connected within the hydrologic cycle?
Some precipitation moves from high areas to low areas on the earth’s surface and into surface water bodies. This is known as surface runoff. Other precipitation seeps into the ground and is stored as groundwater.
Why is groundwater important to watersheds?
Evaporation from surface water bodies combined with evapotranspiration completes the water cycle. It is important to note that groundwater contributes important base flow to streams and lakes. The water balance is the state of equilibrium in the drainage basin between the inputs and outputs.

Describe the relationship between groundwater and surface wa
Surface water is the water that collects on the surface of the earth. On the other hand, groundwater is the water that accumulates into the pores in the …
The Connection between Groundwater and Surface Water
Yet in most watersheds, surface water and groundwater are closely linked. Actions that change one often have an impact on the other.
Groundwater/Surface-Water Interaction | U.S. Geological Survey
Surface water seeps into the ground and recharges the underlying aquifer—groundwater discharges to the surface and supplies the stream with …
Surface Water and Ground Water | Watershed Basics
Ground water is perceived by some to occur as vast underground lakes and rivers, but generally, ground water occurs in voids between soil or rock particles …
How does the flow of groundwater and surface water differ?
Surface water includes the freshwater that is channeled into stream systems, lakes, and wetlands on land. Groundwater, on the other hand, is contained in subterranean aquifers within the rock layers below the water table – the underground boundary that divides the saturated and unsaturated levels of the ground.
Is watershed only for surface water?
The watershed consists of surface water–lakes, streams, reservoirs, and wetlands–and all the underlying groundwater. Larger watersheds contain many smaller watersheds. It all depends on the outflow point; all of the land that drains water to the outflow point is the watershed for that outflow location.
How does the rate of groundwater flow compare with that of ocean currents or river currents?
How does the rate of groundwater flow compare with that of ocean currents or river currents? The rate of groundwater flow is slower than that of surface-water currents.
Which of the following is a true statement about surface water?
Which of the following is a true statement about surface water? It makes up less than 1 percent of all water on Earth. What is the relationship between groundwater and surface water? Surface water percolates through the soil to form groundwater.
What Is Groundwater?

Which of the following choices best describes what happens to the flow of groundwater if a cone of depression is formed?
Which of the following choices best describes what happens to the flow of groundwater if a cone of depression is formed as a result of overpumping? Instead of flowing in one direction, groundwater flows toward the cone of depression from all directions.
How do streams and groundwater interact with one another?
The interaction takes place in three basic ways: streams gain water from inflow of groundwater through the streambed (gaining stream), streams lose water to groundwater by outflow through the streambed (losing stream), or. they do both, gaining in some reaches and losing in other reaches.
Why is groundwater and surface water interactions important to scientists?
The increasing awareness of the relevance of groundwater–surface water interactions leads to increased research into the quantification of water balances in systems with interacting river flow and aquifer dynamics.
What is groundwater and how does it relate to the water table?
The groundwater found below the water table comes from precipitation that has seeped through surface soil. Springs are formed where the water table naturally meets the land surface, causing groundwater to flow from the surface and eventually into a stream, river, or lake.
Which is better surface water or groundwater?
While groundwater generally has a higher mineral content than surface water, it requires less treatment than surface water. To help ensure that customers only receive safe, high quality water, chlorine is added to groundwater to prevent growth of bacteria in the pipes and tanks of the water distribution system.
Where does the water in a watershed go?
A watershed is the area of land where all of the water that drains off of it goes into the same place—a river, stream or lake. The smallest watersheds are the drainage areas for small streams and lakes.
How does groundwater return to the surface?
Water that infiltrates the soil flows downward until it encounters impermeable rock (shown in gray), and then travels laterally. The locations where water moves laterally are called “aquifers”. Groundwater returns to the surface through these aquifers (arrows), which empty into lakes, rivers, and the oceans.
Are groundwater resources independent of surface supplies or are the two interrelated explain your answer?
Groundwater is the part of the hydrologic cycle that lies beneath the ground and is therefore tied to surface supplies.
Is a hydrologic process where water moves downward from surface water to groundwater?
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer.
What is the groundwater?
Ground water is water underground in saturated zones beneath the land surface. Contrary to popular belief, ground water does not form underground “rivers.” It fills the pores and fractures in underground materials such as sand, gravel, and other rock.

Why groundwater is a water resource that is important as a water supply on Earth?
Groundwater is a vital water supply for humanity. Groundwater provides drinking water entirely or in part for as much as 50% of the global population and accounts for 43% of all of water used for irrigation. Worldwide, 2.5 billion people depend solely on groundwater resources to satisfy their basic daily water needs.
Which of the following is a way in which groundwater becomes 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.
