Blue Lake Regional Park
Blue Lake Regional Park is a public park in Fairview, in the U.S. state of Oregon. The park, near the south shore of the Columbia River in Multnomah County, includes many covered and uncovered picnic areas, playing fields for sports such as softball, a cross country course (home course for Portland State Vikings cross country) and infrastructure related to lake recreation including swimming, boating, and fishing. Encompassing wooded areas, three ponds, and a wetland in addition to the lake, the park is frequented by migrating birds and other wildlife. Paved paths run through the park, which is near the 40-Mile Loop hiking and biking trail. Park vegetation includes cottonwoods, willows, and other trees and shrubs as well as wetland plants such as cattails. The lake, which lies in a small artificial drainage basin, has no natural inlet or outlet. Water normally enters the lake only from rain, surface runoff, and groundwater seepage. Excessive aquatic plant life and algae have so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Park
An urban park or metropolitan park, also known as a municipal park (North America) or a public park, public open space, or municipal gardens ( UK), is a park in cities and other incorporated places that offer recreation and green space to residents of, and visitors to, the municipality. The design, operation, and maintenance is usually done by government agencies, typically on the local level, but may occasionally be contracted out to a park conservancy, "friends of" group, or private sector company. Common features of municipal parks include playgrounds, gardens, hiking, running and fitness trails or paths, bridle paths, sports fields and courts, public restrooms, boat ramps, and/or picnic facilities, depending on the budget and natural features available. Park advocates claim that having parks near urban residents, including within a 10-minute walk, provide multiple benefits. History A park is an area of open space provided for recreational use, usually owned and maintain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Washroom
A bathroom or washroom is a room, typically in a home or other residential building, that contains either a bathtub or a shower (or both). The inclusion of a wash basin is common. In some parts of the world e.g. India, a toilet is typically included in the bathroom; in others, the toilet is typically given a dedicated room separate from the one allocated for personal hygiene activities. In North American English the word 'bathroom' is sometimes used to refer to any room in a residence that contains a toilet, regardless of the inclusion of a bath or shower. Historically, bathing was often a collective activity, which took place in public baths. In some countries the shared social aspect of cleansing the body is still important, as for example with '' sento'' in Japan and the "Turkish bath" (also known by other names) throughout the Islamic world. Variations and terminology The term for the place used to clean the body varies around the English-speaking world, as does the ...

Blue Covered Picnic
Blue is one of the three primary colours in the RYB colour model (traditional colour theory), as well as in the RGB (additive) colour model. It lies between violet and cyan on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective. Blue has been an important colour in art and decoration since ancient times. The semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and later, in the Renaissance, to make the pigment ultramarine, the most expensive of all pigments.
