I believe that surface water flows faster because the water does not have to travel through the tiny pores in the rocks like ground water does. Also, ground water is affected my pressure and permeability. Also depends on the slope of the land, the ground water in some regions may move faster than groundwater if its slope is steeper.
The velocity of groundwater is controlled by the hydraulic gradient (i) of the water table or potentiometric surface, the effective Porosity (Ne) of soil or rock, and the hydraulic conductivity (K) of the medium water passes through. This is expressed in the equation V = Ki/Ne (Hudak, 2000). In general, the porosity of an aquifer (amount of interconnected pore spaces) and the hydraulic conductivity (ability of a substance to transmit water) are the main factors that result in differences between groundwater and surface water velocity when the hydraulic gradient (slope) is relatively similar. As the conductivity an aquifer decreases, the the velocity decreases and the gap between groundwater and surface water speed increases. This is reffered to a laminear flow (Hudak, 2000)
In karst Aquifers where dissolution caverns are formed, conditions can mimic those of surface water, resulting in turbulent flow that can match river velocity.

What is the water that seeps through rocks and soil called?
ground water Groundwater is located beneath the soil surface. A sustainable amount of ground water creates an aquifer. The point at which the soil and rocks become completely saturated is the water table. Groundwater will flow to the surface naturally. The study of groundwater is hydrogeology.
What is a groundwater system?
"Groundwater flow is the movement of water that travels and seeps through soil and rock underground. Stored in cavities and geologic pores of the earth's crust, confined groundwater is under a great deal of pressure. Its upper part is lower than the material in which it is confined. Unconfined groundwater is the term for an aquifer with an exposed water surface."
What are the four misconceptions about ground water?
Misconception: Groundwater is a non-renewable resource. Groundwater is constantly renewed by passing from atmospheric or surface water to groundwater in the hydrologic cycle. Misconception: Water from springs is safe without treatment. Although flow through the ground does have a purifying effect on water by filtering sediment, bacteria, and certain chemicals, the purification effect is limited. Large concentrations of chemicals may be too much to be completely removed, and certain chemicals may not be removed by the ground at all. Some groundwater is naturally unsuitable for drinking because of the minerals it has dissolved from the rock through which it flows. Misconception: Groundwater and surface water are separate. Groundwater, surface water, and atmospheric water are intimately related through the earth's water recycling machine, called the hydrologic cycle. Water passes repeatedly through all three parts of the cycle. Misconception: Groundwater flows in underground rivers. Little groundwater flows in open channels beneath the surface. Most flows through fractures in the rock, through millimeter sized opening between layers, and between the grains of the rock.
What is the difference between surface runoff and groundwater flow?
becuase by the geothermal energy consist of seven elements that cause that
How does steepness of slopes affect erosion?
Erosion is driven by the movement of water, or water flow. The steeper the slope, the faster water will flow. The faster water flows, the quicker erosion occurs.
What is the groundwater flow?
The flow of groundwater is an aquifer.
Are base flow same as groundwater?
Base flow is the portion of streamflow that comes from groundwater discharge, but it is not exactly the same as groundwater. Groundwater refers to the water stored underground in aquifers, while base flow specifically refers to the contribution of groundwater to streamflow during dry periods when surface runoff is low.
What is the water that seeps through rocks and soil called?
ground water Groundwater is located beneath the soil surface. A sustainable amount of ground water creates an aquifer. The point at which the soil and rocks become completely saturated is the water table. Groundwater will flow to the surface naturally. The study of groundwater is hydrogeology.
Where does surface water travel?
Surface water flows downhill or seeps into the ground becoming groundwater. The natural flow of surface water is downhill or seaward. See the related link for more information.
How does the rate of groundwater flow compare with that of moving ocean water or river currents?
Groundwater flow is very slow compared to currents in surface water, generally moving at less then one and one-half meters per day.
Does groundwater sometimes flow out of the surface in artesian wells?
True
What is the movement of underground water?
Groundwater flow.

What is the difference between throughflow and groundwater flow?
Through flow is the horizontal movement of water through the soil zone. Groundwater flow is the movement of water through the bedrock, which is typically an aquifer
Is Stream flow down slope?
yes through surface run-off or groundwater flow
What is the movement of water underground called?
Groundwater flow.
What affects groundwater flow?
Groundwater flow is affected by factors such as the permeability of the rock or sediment through which it moves, the slope of the water table, and the presence of fractures or faults that may enhance or restrict flow. Human activities, such as pumping water from wells or constructing barriers like dams, can also influence groundwater flow patterns.
