Matanuska River
The Matanuska River ( Dena'ina: ''Ch'atanhtnu''; Ahtna: ''Ts'itonhna’'') is a 75-mile (121 km) long river in Southcentral Alaska, United States. The river drains a broad valley south of the Alaska Range eponymously known as the Matanuska Valley. Course Formed by the confluence of its east and south forks, the Matanuska River flows generally southwest to the Knik Arm of Cook Inlet. Downstream of its source, the river is joined by meltwater from Matanuska Glacier in the northern Chugach Mountains. From there it continues through the Matanuska Valley, between the Chugach Mountains to the south and the Talkeetna Mountains to the north. Population centers along its course include Chickaloon, Sutton, Palmer, and Butte. It enters the Knik Arm of Cook Inlet about southwest of Palmer and about northeast of Anchorage. The Glenn Highway runs roughly parallel to the river for much of its length. Highway bridges over the river, listed from source to mouth, include Glacier Park B ...

Glenn Highway
The Glenn Highway (part of Alaska Route 1) is a highway in the U.S. state of Alaska, extending from Anchorage near Merrill Field to Glennallen on the Richardson Highway. The Tok Cut-Off is often considered part of the Glenn Highway, for a total length of . Route description The longest stretch of freeway in Alaska runs mostly along the Glenn Highway, beginning in north Anchorage, continuing onto the Parks Highway at the interchange of the two roads, and ending in the city limits of Wasilla, for a total of approximately 38 miles (61 km). This portion of the Glenn Highway is the only road access to Anchorage for most of the state (with the exception of the Kenai Peninsula on the Seward Highway), and as such is the main traffic corridor for Anchorage's suburbs in the Chugiak-Eagle River and Mat-Su areas. The highest point on the highway is at ''Eureka Summit'', which sits on the divide between the Chugach and Talkeetna mountain ranges. History The highway originated as t ...

Knik Arm
Knik Arm ( Dena'ina: ''Nuti'') is a waterway into the northwestern part of the Gulf of Alaska. It is one of two narrow branches of Cook Inlet, the other being Turnagain Arm. Knik Glacier empties into the Knik Arm. The Port of Anchorage is located on the arm. Etymology The Dena'ina name for Knik Arm is ''Nuti'', meaning "salt water". The name "Knik" comes from ''igniq'', the Iñupiaq word for "fire". It has been written Kinik, Kneep, Kneik, Kook, Knuyk, and Kweek. Geography Knik Arm begins at the Inlet's northern edge, near Anchorage, before heading north and east. It is about long, and at its upper end, receives the waters of the Matanuska River. West of Knik Arm is the delta of the Susitna River, the largest stream emptying into the inlet. At the head of Knik Arm, at the mouth of Knik River, was the village (ghost town) of Knik. Knik Arm's other major tributaries are Ship Creek, Eagle River, Peter's Creek, Eklutna River and Fish Creek. The greater part of the plain, ...

Stream Gauge
A stream gauge, streamgage or stream gauging station is a location used by hydrologists or environmental scientists to monitor and test terrestrial bodies of water. Hydrometric measurements of water level surface elevation ("stage") and/or volumetric discharge (flow) are generally taken and observations of biota and water quality may also be made. The locations of gauging stations are often found on topographical maps. Some gauging stations are highly automated and may include telemetry capability transmitted to a central data logging facility. Measurement equipment Automated direct measurement of streamflow discharge is difficult at present. In place of the direct measurement of streamflow discharge, one or more surrogate measurements can be used to produce discharge values. In the majority of cases, a stage (the elevation of the water surface) measurement is used as the surrogate. Low gradient (or shallow-sloped) streams are highly influenced by variable downstream c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

Braided River
A braided river, or braided channel, consists of a network of river channels separated by small, often temporary, islands called braid bars or, in English usage, ''aits'' or ''eyots''. Braided streams tend to occur in rivers with high sediment loads or coarse grain sizes, and in rivers with steeper slopes than typical rivers with straight or meandering channel patterns. They are also associated with rivers with rapid and frequent variation in the amount of water they carry, i.e., with "flashy" rivers, and with rivers with weak banks. Braided channels are found in a variety of environments all over the world, including gravelly mountain streams, sand bed rivers, on alluvial fans, on river deltas, and across depositional plains. Description A braided river consists of a network of multiple shallow channels that diverge and rejoin around ephemeral ''braid bars''. This gives the river a fancied resemblance to the interweaved strands of a braid. The braid bars, also known as channel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Main Stem
In hydrology, a mainstem (or trunk) is "the primary downstream segment of a river, as contrasted to its tributaries". Water enters the mainstem from the river's drainage basin, the land area through which the mainstem and its tributaries flow.. A drainage basin may also be referred to as a ''watershed'' or ''catchment''. Hydrological classification systems assign numbers to tributaries and mainstems within a drainage basin. In the Strahler number, a modification of a system devised by Robert E. Horton in 1945, channels with no tributaries are called "first-order" streams. When two first-order streams meet, they are said to form a second-order stream; when two second-order streams meet, they form a third-order stream, and so on. In the Horton system, the entire mainstem of a drainage basin was assigned the highest number in that basin. However, in the Strahler system, adopted in 1957, only that part of the mainstem below the tributary of the next highest rank gets the highest num ...

Palmer Hay Flats State Game Refuge
The Palmer Hay Flats State Game Refuge is located in Alaska, south of Wasilla and north of Anchorage. It is composed of of coastal marshy areas adjacent to Knik Arm that support populations of moose, muskrat, foxes, coyotes, eagles, and migratory waterfowl.
