discharge. the volume of water flowing past a certain point in a given amount of time. headwaters.
Discharge measurements are made at each gaging station to determine the discharge rating for that site. This lesson reviewed the techniques and instruments used to measure stream velocity and to calculate stream discharge.
Discharge is usually expressed in units of cubic feet per second (cfs or ft 3 /sec). With rare exception, stream discharge is not measured directly, but is computed indirectly from velocity and water level (stage) measurements.
The USGS currently uses the midsection method of computing stream discharge using current meter velocity measurements. In this method, the stream cross section is divided into rectangular subsections as shown in Figure 5.1.
What is the discharge quizlet?
Discharge:(Q) = (width)(depth)(velocity) The volume of water to pass a given point on a stream bank per unit of time, usually expressed in cubic meters of water per second.
What is discharge geology quizlet?
Discharge is the measure of stream flow – the volume of water flowing through some stretch of a stream during a specified period of time.
How is stream discharge determined quizlet?
Hydrologists often use the following equation to determine stream discharge: Q = wdv; where Q = discharge; w = channel width; d = channel depth; and v = stream velocity. A field hydrologist is recording stream discharge and observes discharge increasing.
What two measurements would you need to calculate the discharge of a stream quizlet?
The discharge of a stream is the product of its velocity (V – length of travel per unit of time such as feet/second) times depth of the water (D – unit of length) times width (W of the water – units of length). (Make sure all all three lengths are expressed in the same unit.)
How has the Mississippi delta been formed over time?
Time, weather, and human intervention have all shaped the Mississippi Delta in Louisiana, a giant bird’s foot shape protruding into the Gulf of Mexico. The Mississippi River deposits sediment into the ocean, and over 25 years, NASA Landsat satellites observed changes in the delta’s shape.
What is the cause of the hypoxic zone in the Gulf?
Hypoxia is believed to be caused primarily by excess nutrients delivered from the Mississippi River in combination with seasonal stratification of Gulf waters. Excess nutrients promote algal and attendant zooplankton growth.
What has caused the hypoxic dead zone?
Hypoxic zones can occur naturally, but scientists are concerned about the areas created or enhanced by human activity. There are many physical, chemical, and biological factors that combine to create dead zones, but nutrient pollution is the primary cause of those zones created by humans.
What is the major cause of hypoxic areas near the coast?
The cause of such “hypoxic” (lacking oxygen) conditions is usually eutrophication, an increase in chemical nutrients in the water, leading to excessive blooms of algae that deplete underwater oxygen levels.
What are the consequences of spreading dead zones on marine ecosystem?
As the dead zones increase, the oxygen needed for marine organisms to survive reduces drastically. This reduced oxygen levels hinder biological activity leading to barren patches in water bodies. Habitats in marine areas like kelps and corals are home to large number of organisms like fishes and other arthropods.
Why are ocean dead zones a problem?
Dead zones are areas of water bodies where aquatic life cannot survive because of low oxygen levels. Dead zones are generally caused by significant nutrient pollution, and are primarily a problem for bays, lakes and coastal waters since they receive excess nutrients from upstream sources.
What is a dead zone in the marine environment?
Dead zones are bodies of water that do not have sufficient oxygen (3) levels in order to support most marine life. Dead zones are caused by oxygen-depleting factors which include, but are not limited to, human pollution (4).
How does the dead zone effect fish?
Dead zones are areas in bodies of water like the Chesapeake Bay that have little to no oxygen. Fish, crabs, oysters and other aquatic life literally suffocate in these zones.
