Fiesta Island, Mission Bay
Mission Bay is a human-made saltwater bay located south of the Pacific Beach community of San Diego, California created from approximately of historical wetland, marsh, and saltwater bay habitat. The bay is part of the recreational Mission Bay Park, the largest man-made aquatic park in the United States, consisting of , approximately 46% land and 54% water. The combined area makes Mission Bay Park the ninth largest municipally-owned park in the United States. The bay was created to enhance recreational opportunities in San Diego, but doing so has fundamentally altered the ecology of San Diego county by removing all but , or approximately 5%, of wetland habitat. Wakeboarding, jet skiing, sailing, camping, cycling, jogging, roller skating and skateboarding, or sunbathing are all popular around the bay.

Time Trial
In many racing sports, an athlete (or occasionally a team of athletes) will compete in a time trial against the clock to secure the fastest time. The format of a time trial can vary, but usually follow a format where each athlete or team sets off at a predetermined interval to set the fastest time on a course. Variation in sports Cycling In cycling, for example, a time trial (TT) can be a single track cycling event, or an individual or team time trial on the road, and either or both of the latter may form components of multi-day stage races. In contrast to other types of races, athletes race alone since they are sent out in intervals (interval starts), as opposed to a mass start. Time trialist will often seek to maintain marginal aerodynamic gains as the races are often won or lost by a couple of seconds. Skiing In cross-country skiing and biathlon competitions, skiers are sent out in 30 to 60 second intervals. Rowing In rowing, time trial races, where the boats are ...

Weir
A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. Etymology There is no single definition as to what constitutes a weir and one English dictionary simply defines a weir as a small dam, likely originating from Middle English ''were'', Old English ''wer'', derivative of root of ''werian,'' meaning "to defend, dam". Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more navigable by boat. In some locations, the terms dam and weir are synonymous, but normally there is a clear distinction made between the structures. Usually, a dam is designed specifically to impound water beh ...

Levee
A levee (), dike (American English), dyke (Commonwealth English), embankment, floodbank, or stop bank is a structure that is usually earthen and that often runs parallel to the course of a river in its floodplain or along low-lying coastlines. The purpose of a levee is to keep the course of rivers from changing and to protect against flooding of the area adjoining the river or coast. Levees can be naturally occurring ridge structures that form next to the bank of a river, or be an artificially constructed fill or wall that regulates water levels. Ancient civilizations in the Indus Valley, ancient Egypt, Mesopotamia and China all built levees. Today, levees can be found around the world, and failures of levees due to erosion or other causes can be major disasters. Etymology Speakers of American English (notably in the Midwest and Deep South) use the word ''levee'', from the French word (from the feminine past participle of the French verb , 'to raise').

San Diego River
The San Diego River is a river in San Diego County, California. It originates in the Cuyamaca Mountains northwest of the town of Julian, then flows to the southwest until it reaches the El Capitan Reservoir, the largest reservoir in the river's watershed at . Below El Capitan Dam, the river runs west through Santee and San Diego. While passing through Tierrasanta it goes through Mission Trails Regional Park, one of the largest urban parks in America. It flows near the Mission San Diego de Alcalá. The river's valley downstream from there is known as Mission Valley for that reason. The valley forms a transportation corridor for Interstate 8 and for the San Diego Trolley Green Line. The river discharges into the Pacific Ocean near the entrance to Mission Bay, forming an estuary. History The river has changed its course several times in recorded history. Prior to 1821, the San Diego River usually entered San Diego Harbor. In the fall of 1821, however, a flood changed th ...

San Diego Bay
San Diego Bay is a natural harbor and deepwater port located in San Diego County, California near the U.S.–Mexico border. The bay, which is long and wide, is the third largest of the three large, protected natural bays on California's of coastline, after San Francisco Bay and Humboldt Bay. The highly urbanized land adjacent to the bay includes the city of San Diego (eighth-largest in the United States) and four other cities: National City, Chula Vista, Imperial Beach and Coronado. Considered to be one of the best natural harbors on the west coast of North America, it was colonized by Spain beginning in 1769. Later it served as base headquarters of major ships of the United States Navy in the Pacific until just before the United States entered World War II, when the newly organized United States Pacific Fleet primary base was transferred to Pearl Harbor, Hawaii. However, San Diego Bay remains as a home port of major assets, including several aircraft carriers, of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juan Rodríguez Cabrillo
Juan Rodríguez Cabrillo ( pt, João Rodrigues Cabrilho; c. 1499 – January 3, 1543) was an Iberian maritime explorer best known for investigations of the West Coast of North America, undertaken on behalf of the Spanish Empire. He was the first European to explore present-day California, navigating along the coast of California in 1542–1543 on his voyage from New Spain (modern Mexico). Nationality Cabrillo's nationalityPortuguese or Spanishhas been debated for centuries. He was described as Portuguese by Spanish chronicler Antonio de Herrera y Tordesillas; in his ''Historia General de los hechos de los Castellanos en las Islas y tierra firme del Mar Oceano'', written 60 years after Cabrillo's death, Herrera referred to Cabrillo as ''Juan Rodriguez Cabrillo''. Several locations in Portugal claim to be his birthplace. However, the source for Herrera's description is unknown. Some historians have long believed that Cabrillo was from Spain, and a set of documents discovered i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

H1 Unlimited
H1 Unlimited is an American Unlimited Hydroplane racing league that is sanctioned by the American Power Boat Association (APBA). Until 2009, the series was known as ABRA Unlimited Hydroplane, in turn renamed from APBA Unlimited Hydroplane in 2004. The H1 Unlimited season typically runs from July through September, consisting of five races. A hydroplane (or ''hydro'', or ''thunderboat'') is a very specific type of motorboat used exclusively for racing. One of the unique characteristics about hydroplanes is that they only use the water they're on for propulsion and steering (not for flotation) - when going at full speed they are primarily held aloft by a principle of fluid dynamics known as " planing," with only a tiny fraction of their hull actually touching the water. History The unlimited hydroplane racing series was founded in 1946 when the unlimited class of boats was allowed to compete following World War II and the subsequent availability of surplus aircraft engines.
