North Shore Channel
The North Shore Channel is a 7.7 mile long canal built between 1907 and 1910 to increase the flow of North Branch of the Chicago River so that it would empty into the South Branch and the Chicago Sanitary and Ship Canal. Its water is generally taken from Lake Michigan to flow into the canal at Wilmette Harbor. Its carrying of excess run-off in high water events has been largely taken over by the Chicago Deep Tunnel, but there are still occasional intentional discharges back into the lake, as flood prevention in times of very heavy rains, causing episodic concern regarding effects on lake water quality. Geography The North Shore Channel, a component of the Chicago Area Waterway System (CAWS), flows from Lake Michigan, near the Bahá'í House of Worship in Wilmette, Illinois, to the North Branch of the Chicago River in Chicago. The channel begins at the Wilmette Pumping Station, where sluice gates are generally used to provide for a consistent water level in the channel by cont ...

Rowing (sport)
Rowing, often called crew American English, in the United States, is the sport of racing boats using Oar (sport rowing), oars. It differs from paddling sports in that rowing oars (called blades in the United Kingdom) are attached to the boat using Rowlock, rowlocks, while paddles are not connected to the boat. Rowing is divided into two disciplines: sculling and sweep rowing. In sculling, each rower (or oarsman) holds two oars, one in each hand, while in sweep rowing each rower holds one oar with both hands. There are several boat classes in which athletes may compete, ranging from single sculls, occupied by one person, to shells with eight rowers and a coxswain (rowing), coxswain, called eight (rowing), eights. There are a wide variety of course types and formats of racing, but most elite and championship level racing is conducted on calm water courses long with several lanes marked using buoys. Modern rowing as a competitive sport can be traced to the early 17th century whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kayak
] A kayak is a small, narrow human-powered watercraft typically propelled by means of a long, double-bladed paddle. The word ''kayak'' originates from the Inuktitut word '' qajaq'' (). In British English, the kayak is also considered to be a kind of canoe. There are countless different types of kayaks due to the craft being easily adaptable for different environments and purposes. The traditional kayak has an enclosed deck and one or more cockpits, each seating one occupant or kayaker, differentiating the craft from an open-deck canoe. The cockpit is sometimes covered by a spray deck that prevents unwanted entry of water from waves or splashes. Even within these confines, kayaks vary vastly in respect to materials, length, and width, with some kayaks such as the sprint kayak designed to be fast and light, and others such as the whitewater kayak designed to be sturdy and maneuverable. Some modern paddlecrafts, which still claim the title "kayak", remove integral parts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canoe
A canoe is a lightweight, narrow watercraft, water vessel, typically pointed at both ends and open on top, propelled by one or more seated or kneeling paddlers facing the direction of travel and using paddles. In British English, the term ''canoe'' can also refer to a kayak, whereas canoes are then called Canadian (canoe), Canadian or open canoes to distinguish them from kayaks. However, for official competition purposes, the American distinction between a kayak and a canoe is almost always adopted. At the Olympics, both conventions are used: under the umbrella terms Canoe Slalom and Canoe Sprint, there are separate events for canoes and kayaks. Culture Canoes were developed in cultures all over the world, including some designed for use with sails or outriggers. Until the mid-19th century, the canoe was an important means of transport for exploration and trade, and in some places is still used as such, sometimes with the addition of an outboard motor. Where the canoe play ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crappie
Crappies () are two species of North American freshwater fish of the genus ''Pomoxis'' in the family Centrarchidae (sunfishes). Both species of crappies are popular game fish among recreational anglers. Etymology The genus name ''Pomoxis'' literally means "sharp cover", referring to the fish's spiny gill covers (opercular bones). It is composed of the Greek (, cover) and (, "sharp"). The common name (also spelled ''croppie'' or ''crappé'') derives from the Canadian French , which refers to many different fishes of the sunfish family. Other names for crappie are papermouths, strawberry bass, speckled bass or specks (especially in Michigan), speckled perch, white perch, crappie bass, calico bass (throughout the Middle Atlantic states and New England), and Oswego bass. In Louisiana, it is called sacalait (, ), seemingly an allusion to its milky white flesh or silvery skin. The supposed French meaning is, however, folk etymology, because the word is ultimately from Cho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canal Shores Golf Course
Canal Shores Golf Course (formerly known as the Peter N. Jans Memorial Golf Course and the Evanston Wilmette Community Golf Course) is an 82-acre, 18-hole, par 60 golf course located in a suburban residential neighborhood on the east side of Evanston, Illinois, and Wilmette, Illinois. Founded in 1919 on the banks of the North Shore Channel of the Chicago River, the course is 3,904 yards in length, featuring a narrow and tree-lined fairway and two over-the-water holes. Eleven of the holes are located in Evanston, Illinois, and seven holes are in Wilmette, Illinois. History Peter N. Jans, a golf professional and Evanston civic leader, championed the reclamation of the undeveloped canal banks for a golf course in north Evanston. Todd Sloan, who also laid out the back nine of the Racine Country Club in Wisconsin, is credited as the architect of the present-day Canal Shores Golf Course, which has been renamed several times during the past century. The course was built on the site of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riffle-pool Sequence
In a flowing stream, a riffle-pool sequence (also known as a pool-riffle sequence) develops as a stream's hydrological flow structure alternates from areas of relatively shallow to deeper water. This sequence is present only in streams carrying gravel or coarser sediments. Riffles are formed in shallow areas by coarser materials, such as gravel deposits, over which water flows. Pools are deeper, calmer areas whose bed load (in general) is made up of finer material such as silt. Streams with only sand or silt laden beds do not develop the feature. The sequence within a stream bed commonly occurs at intervals of from 5 to 7 stream widths. Meandering streams with relatively coarse bed load tend to develop a riffle-pool sequence with pools in the outsides of the bends and riffles in the ''crossovers'' between one meander A meander is one of a series of regular sinuous curves in the Channel (geography), channel of a river or other watercourse. It is produced as a watercourse er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Army Corps Of Engineers
The United States Army Corps of Engineers (USACE) is the military engineering branch of the United States Army. A direct reporting unit (DRU), it has three primary mission areas: Engineer Regiment, military construction, and civil works. USACE has 37,000 civilian and military personnel, making it one of the world's largest public engineering, design, and construction management agencies.

Civilians do not function as active duty military and are not required to be in active war and combat zones; however, volunteer (with pay) opportunities do exist for civilians to do so. The day-to-day activities of the three mission areas are administered by a lieutenant general known as the chief of engineers/commanding general. The chief of engineers commands the Engineer Regiment, comprisi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunnel And Reservoir Plan
The Tunnel and Reservoir Plan (abbreviated TARP and more commonly known as the Deep Tunnel Project or the Chicago Deep Tunnel) is a large civil engineering project that aims to reduce flooding in the metropolitan Chicago area, and to reduce the harmful effects of flushing raw sewage into Lake Michigan by diverting storm water and sewage into temporary holding reservoirs. The megaproject is one of the largest civil engineering projects ever undertaken in terms of scope, cost and timeframe. Commissioned in the mid-1970s, the project is managed by the Metropolitan Water Reclamation District of Greater Chicago. Completion of the system is not anticipated until 2029, but substantial portions of the system have already opened and are currently operational. Across 30 years of construction, over $3 billion has been spent on the project. History 19th century The Deep Tunnel Project is the latest in a series of civil engineering projects dating back to 1834. Many of the problems experience ...

Ponding
In civil engineering, ponding is the (typically) unwanted pooling of water, typically on a flat roof or roadway. Ponding water accelerates the deterioration of many materials, including seam adhesives in single-ply roof systems, steel equipment supports, and particularly roofing asphalt. On low-slope asphalt roofs, ponding water allows the oil solvent components of the asphalt to leach out and evaporate, leaving the roof membrane brittle and susceptible to cracking and leaking in the ponding location. The time taken for water to saturate a zone, usually from rainfall, causing a pond to form, is referred to as the "ponding time". Cause Most flat roof systems (properly called "low-slope roof systems") are designed with a slight pitch to shed water off the sides, usually into gutters, scuppers, internal drains, or a combination of these. When a scupper or drain is clogged or fails for other reasons, storm water tends to pool around that low area. Over time, with each passing stor ...
