River Engineering
River engineering is a discipline of civil engineering which studies human intervention in the course, characteristics, or flow of a river with the intention of producing some defined benefit. People have intervened in the natural course and behaviour of rivers since before recorded history—to manage the water resources, to protect against flooding, or to make passage along or across rivers easier. Since the Yuan Dynasty and Ancient Roman times, rivers have been used as a source of hydropower. From the late 20th century, the practice of river engineering has responded to environmental concerns broader than immediate human benefit. Some river engineering projects have focused exclusively on the restoration or protection of natural characteristics and habitats. Hydromodification encompasses the systematic response to alterations to riverine and non-riverine water bodies such as coastal waters (estuaries and bays) and lakes. The U.S. Environmental Protection Agency (EPA) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Colorado Street Bridge (Pasadena, California)
The Colorado Street Bridge is a historic concrete arch bridge spanning the Arroyo Seco in Pasadena, California.

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eaton Wash
Eaton Canyon is a major canyon beginning at the Eaton Saddle near Mount Markham and San Gabriel Peak in the San Gabriel Mountains in the Angeles National Forest, United States. Its drainage flows into the Rio Hondo river and then into the Los Angeles River. It is named after Judge Benjamin S. Eaton, who lived in the Fair Oaks Ranch House in 1865 not far from Eaton Creek. The most well-known portion of the canyon is the Eaton Canyon Nature Center in Pasadena, California. The trailhead of the Mount Wilson Toll Road is in the canyon. History Eaton Canyon is in the foothills of the San Gabriel Mountains. Originally called "El Precipicio" by the Spanish settlers because of its steep gorges, the canyon falls under several governmental jurisdictions. Benjamin Eaton was hired by Don Benito Wilson to bring water to the Fair Oaks Ranch. In August 1877, naturalist John Muir set out from Pasadena for an expedition into the San Gabriels.
