Ensenada is a city in Ensenada Municipality, Baja California, situated on the Pacific Coast of Mexico. Located on the Bahía de Todos Santos, the city had a population of 279,765 in 2018, making it the third-largest city in Baja California. The city is an important international trade center and home to the Port of Ensenada, the second-busiest port in Mexico. Ensenada is a major tourist destination, owing to its warm Mediterranean climate and proximity to the Pacific Ocean, and is commonly known as ''La Cenicienta del Pacífico'' ("The Cinderella of the Pacific"). Ensenada was founded in 1882, when the small community of Rancho Ensenada de Todos Santos was made the regional capital for the northern partition of the Baja California Territory. The city grew significantly with the proliferation of mines in the surrounding mountains. While the Mexican Revolution curtailed much of Ensenada's expansion, the onset of Prohibition in the United States transformed the city into a popul ...

Tijuana River Estuary
The Tijuana River Estuary is an intertidal coastal wetland at the mouth of the Tijuana River in San Diego County, California, in the United States bordering Tijuana, Baja California, Mexico. It is the location of the Tijuana River National Estuarine Research Reserve, Tijuana Slough National Wildlife Refuge, Border Field State Park, and Tijuana River Valley Regional Park. The estuary is a shallow water habitat. Often termed an intermittent estuary since its volume is subject to the discharge controlled by the seasons of the year, the volume of the estuary fluctuates and at times there is dry land, or flooded areas. It was designated a National Natural Landmark in 1973. Ecology The estuary is one of the few remaining salt marshes on the South Coast. Its location positions it under the path of the Pacific Flyway, where it serves as a stopover point. It is the largest remaining natural coastal area between Santa Barbara, California and San Quintín, Baja California. Three times the size ...

Flood
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting ...

Pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have an anthropogenic source – that is, a source created by human activities. Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed nine million people worldwide (one in six deaths). This remained unchanged in 2019, with little real progress against pollution being identifiable. Air pollution accounted for of these earlier deaths. Major forms of pollution include air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioactiv ...

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 seawater, saltwater. The main w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tecate Creek
Tecate Creek is a stream in northern Baja California, Mexico with its headwaters in southern San Diego County, California in the United States. It begins along the Tecate Divide in the In-Ko-Pah Mountains, near Live Oak Springs. The upper reaches of the stream in the US are known as Campo Creek. It flows southwest, crossing the Mexico–United States border at Canyon City, before flowing through the city of Tecate, Baja California. West of Tecate it flows through a gorge and briefly re-enters the US where it combines with Cottonwood Creek to form the Rio Alamar, a tributary of the Tijuana River which it joins in Central Tijuana. The portion of Tecate Creek in Mexico is about long. Combined with Campo Creek in the US, it is , making it one of the longest tributaries of the Tijuana River. See also *List of rivers of Mexico This is a list of rivers of Mexico, listed from north to south. There are 246 rivers on this list. Alternate names for rivers are given in parentheses. River ...

Barrett Dam
Barrett Dam is a concrete arch-gravity dam in southern San Diego County, California in the United States, forming Barrett Lake on Cottonwood Creek.
