It refers to the ridges and hills that separate two watersheds.
Drainage divide
3
Surface water is water located on top of land, forming terrestrial (surrounding by land on all sides) waterbodies, and may also be referred to as:
Blue Water
4
Rainfall causes rivers to rise, and a river can even rise if it only rains very far up in the watershed.
True
5
Infiltration characteristics of a watershed will determine the amount of precipitation which is stored below the surface of the soil.
True
6
This is defined as freshwater taken from ground or surface water sources (such as rivers or lakes), either permanently or temporarily, and used for agricultural, industrial or municipal (domestic) uses.
Water Withdrawal
7
Precipitation is the most important element influencing streamflow is the quantity of hydrological cycle in the watershed as rainfall or snow.
True
8
A large hollow that forms shortly after the top of a volcano is blown off or collapses during an eruption.
Caldera
9
According to USGS (U.S. Geological Survey) water-use reports, surface water is considered freshwater when it contains ____ of dissolved solids.
less than 1000 milligrams per liter
10
The ocean is the body of salt water that covers approximately 97% of the Earth and contains 70.8% of Earth’s water.
False
11
It is the elevation of the water surface above a datum.
Stream Stage
12
Stream order is a numbering system for the surface drainage segments which can assist in the identification of hydrographs.
True
13
Other term for Permanent Surface Water.
Perennial Surface Water
14
Of all the water on Earth, just 3% is fresh water.
True
15
This information includes areas, slopes, depression areas, and any stream patterns on the watershed.
Topographical
16
It refers to bodies of water that convey flow for a short duration and in direct response to a precipitation event.
Ephemeral Surface Water
17
It is the volume of water that moves over a designated point over a fixed period of time. It is often expressed as cubic feet per second.
Discharge
18
The flow of a stream is directly related to the amount of water moving off the watershed into the stream channel.
True
19
Troughs in the hydrograph are usually a result of precipitation events, while peaks represent drier times.
False
20
Ephemeral Surface Water includes lakes, rivers and wetlands (marshes and swamps).
False
21
It is an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel.
All of the above
22
A chart showing the distribution of rainfall over a particular period of time or a particular area.
Hyetograph
23
What is the largest area of the ocean in the planet?
Pacific
24
Ephemeral surface waters are present year-round, and is replenished with groundwater when there is little precipitation.
False
25
Not all water goes directly to the sea. When rain falls on dry ground, it has the ability to seep into or enter the earth.
True
26
A periodic meter measurement of flow and simultaneous stage observations provide data for a calibration curve.
Rating Curve
27
Perennial Surface Water includes creeks, lagoons and waterholes.
False
28
It shows the temporal change in flow, or discharge, per unit of runoff.
Unit Hydrograph
29
Streams are important as conduits in the water cycle, instruments in groundwater recharge, and corridors for fish and wildlife migration.
True
30
Drainage divide refers to the ridges and hills that separate two watersheds.
True
31
The watershed includes water resources (lakes, rivers, dams, and wetlands) as well as all underlying groundwater collected from rains.
True
32
It is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power.
Hydropower
33
It is a natural exit point at which groundwater emerges out of the aquifer and flows onto the top of the Earth's crust to become surface water.
Spring
34
It is a naturally occurring, relatively large body of water localized in a basin completely surrounded by dry land, with much slower-moving flow than any inflow or outflow streams that serve to feed or drain it.
Lake
35
Water falling on steeply-sloped land runs off more quickly than water falling on flat land.
True
36
Sometimes the top of a volcano is blown off or collapses during an eruption, leaving a depression called a caldera.
True
37
These are either marginal sea or second-order sections of the oceanic sea.
Particular seas
38
Type of surface water that can be continued by infrastructures that humans have assembled. This includes artificial lakes, canals and artificial ponds or swamps.
Artificial Surface Water
39
While surface water can seep underground to become groundwater, groundwater can resurface on land to replenish surface water. Springs are formed in these locations.
True
40
Soils absorbing more water results in more runoff overland into streams.
False
