Ravenna Creek
Ravenna Creek is a stream in the Ravenna and Roosevelt neighborhoods of Seattle, Washington, whose present daylighted length of nearly is entirely within the Ravenna & Cowen Parks. Ravenna Creek used to drain Green Lake into Lake Washington's Union Bay, but urban development and the lowering of the two lakes in 1911 and 1916 resulted in the disappearance of the creekbed between Green Lake and Cowen Park and between Ravenna Park and Union Bay. Ravenna Creek's current source is a wetland in the northwest corner of Cowen Park, at NE 62nd Street and Brooklyn Avenue NE. It is also fed by springs throughout Ravenna Park, and is joined there by a second branch which begins near the intersection of NE 65th Street and 23rd Avenue NE. Until 2006, the creek ended at a sewer grate where the park's trail system opened into a soccer field. A daylighting project completed in May 2006 disconnected the creek from the sewer system and extended its bed towards the southeast corner of Ravenn ...

Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or saltwater. The main wetland typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Seattle
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yesler Creek
Yesler Creek is a stream that originates in the Bryant and Wedgwood neighborhoods of Seattle, Washington, and flows southward to empty into Union Bay of Lake Washington. Portions are daylighted, such as those flowing between 39th and 40th Avenue NE and through Burke Gilman Park. The stream also continues underground underneath Seattle Children's Hospital. Restoration Members of the Green Seattle Partnership and the University of Washington Restoration Ecology Network (UW-REN) have conducted work parties to mulch, clear invasive plants and plant native vegetation around the stream in Burke Gilman Park See also * Ravenna Creek * Thornton Creek Thornton Creek is of urban creeks and tributaries from southeast Shoreline through northeast Seattle to Lake Washington.

Thornton Creek
Thornton Creek is of urban creeks and tributaries from southeast Shoreline through northeast Seattle to Lake Washington. Its watershed, the largest in Seattle, exhibits relatively dense biodiversity for an urban setting;Brokaw it is home to frogs, newts, ducks, herons, and beavers, in addition to more than 75,000 people. From west of Jackson Park Golf Course in Shoreline,Hodson from Sunny Walter-Pillings PondWalter in Licton Springs–North College Park, and north Northgate Thornton Creek flows through Maple Leaf and Lake City, including the Victory Heights, Meadowbrook, and Matthews Beach neighborhoods, and empties into the lake at Matthews Beach Park. Habitat and stewardship Thornton Creek flows through Meadowbrook Pond, known for its birdwatching and resident beavers. The Thornton creek watershed is land formerly inhabited by the Duwamish tribe. One of the Duwamish's historic longhouse sites was located near the mouth of Thornton Creek at Mathews beach. Early i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Water Resources
Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. 97% of the water on the Earth is salt water and only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air. Natural sources of fresh water include surface water, under river flow, groundwater and frozen water. Artificial sources of fresh water can include treated wastewater (wastewater reuse) and desalinated seawater. Human uses of water resources include agricultural, industrial, household, recreational and environmental activities. Water resources are under threat from water scarcity, water pollution, water conflict and climate change. Fresh water is a renewable resource, yet the world's supply of groundwater is steadily decreasing, wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stream
A stream is a continuous body of surface water flowing within the bed and banks of a channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighting (streams), daylighted subterranean river, subterranean water, and surfaced groundwater (Spring (hydrology), spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls. Streams are importan ...

Wastewater
Wastewater is water generated after the use of freshwater, raw water, drinking water or saline water in a variety of deliberate applications or processes. Another definition of wastewater is "Used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff / storm water, and any sewer inflow or sewer infiltration". In everyday usage, wastewater is commonly a synonym for sewage (also called sewerage, domestic wastewater, or municipal wastewater), which is wastewater that is produced by a community of people. As a generic term wastewater may also be used to describe water containing contaminants accumulated in other settings, such as: * Industrial wastewater: waterborne waste generated from a variety of industrial processes, such as manufacturing operations, mineral extraction, power generation, or water and wastewater treatment. ** Cooling water, released with potential thermal pollution after use to condense steam or reduce ma ...

University Slough
The Union Bay Natural Area (UBNA) in Seattle, Washington, also known as Union Bay Marsh, is the restored remainder of the filled former Union Bay and Union Bay Marsh. It is located at the east end of the main University of Washington campus, south of NE 45th Street and west of Laurelhurst. Ravenna Creek is connected to University Slough (Drainage Canal), thence to Union Bay, and Lake Washington. Drainage Canal is one of three or four areas of open water connected with Lake Washington around Union Bay Marsh. The canal extends from NE 45th Street, between the driving range and IMA Sports Field 1, south to the bay, ending southeast of the Husky Ballpark baseball grandstand (northeast of the IMA Building). The Drainage Canal that carries Ravenna Creek past UBNA to Union Bay is locally sometimes called University Slough. The little grasslands, modest ponds, and lake shoreline of the UBNA is a sanctuary for birds (including double-crested cormorants, great blue herons, and ...

Daylighting (streams)
Daylighting can be defined as "opening up buried watercourses and restoring them to more natural conditions". An alternative definition refers to "the practice of removing streams from buried conditions and exposing them to the Earth's surface in order to directly or indirectly enhance the ecological, economic and/or socio-cultural well-being of a region and its inhabitants”. The term is used to refer to the restoration of an originally open-air watercourse, which had at some point been diverted below ground, back into an above-ground channel. Typically, the rationale behind returning the riparian environment of a stream, wash, or river to a more natural state is to reduce runoff, create habitat for species in need of it, or improve an area's aesthetics. In the UK, the practice is also known as deculverting. In addition to its use in urban design and planning the term also refers to the public process of advancing such projects. According to the Planning and Development De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soccer
Association football, more commonly known as football or soccer, is a team sport played between two teams of 11 players who primarily use their feet to propel the ball around a rectangular field called a pitch. The objective of the game is to score more goals than the opposition by moving the ball beyond the goal line into a rectangular framed goal defended by the opposing side. Traditionally, the game has been played over two 45 minute halves, for a total match time of 90 minutes. With an estimated 250 million players active in over 200 countries, it is considered the world's most popular sport. The game of association football is played in accordance with the Laws of the Game, a set of rules that has been in effect since 1863 with the International Football Association Board (IFAB) maintaining them since 1886. The game is played with a football that is in circumference. The two teams compete to get the ball into the other team's goal (between the posts and under ...
