Drainage basin

approximately 70 million years ago and caused the formation of the Rocky Mountains. Later, around 18 million years ago, the Basin and Range Province was created and began the flow of water through the modern-day Grand Canyon area. Finally, around 6 million years ago, the Gulf of California opened up and sent a large river flowing through the area, which joined with the drainage coming from the Basin…

occasional storm surges from tropical and frontal events, and these effects de-crease upstream. Deltas have been growing in the relatively shallow Atchafalaya Bay and initially emerged after a large river flood in 1973. The Atchafalaya is the most original basins because it has a growing system with very stable wetlands. It is also the biggest river swamp in North America but has lost about 3,760 acres between 1932 and 1990. The loss of the wetlands is primarily due to erosion, human activities,…

It is common for rainfall to be localized and heavy resulting in flash flooding in drainage basins that are typically dry most of the year. Areas that have suffered from a recent wildfire can be even more at risk due to the lack of vegetation and soil stability as seen in the Payson flash flood (Vandell & Dungan,…

Stormwater runoff brings many problems besides polluting the Bay. It causes a chain reaction of negative events such as killing the native life in the watershed, causing diseases in humans, polluting the air, and loss to the economy. It’s more than simply making the water look repulsive. Stormwater runoff hurts the Bay, and there are simple everyday actions citizens can do to benefit to the Bay. The government can only do so much to protect the Bay. Citizens can build ourselves, volunteer, and…

Ever since its rediscovery in 1911, Machu Picchu has acted as an archaeological magnet, capturing and drawing in the attention of countless researchers, historians, and tourists. Located between the Peruvian Andes and the Amazon Basin, Machu Picchu is a site of incredible fascination due to both its historical and scientific contributions as well as its emotional contributions, demonstrating a significant and even precious connection between object and man. In this essay, I will not only expand…

coast and will leave an abundance of people stranded on the streets or at schools. Furthermore, human health is a major area for concern as sea levels continue to rise. Because “saltwater intrusion into fresh water increases salinity of groundwater basins and well water,” the risk of vector-borne and diarrheal disease is remarkably higher (“Sea Level Rise, Climate Change and Health”). These diseases will result in a loss of income for afflicted individuals due to non-working days and will lead…

Hydrologic modeling suggests that green roofs alone cannot provide complete stormwater management at the watershed scale. Other studied have found benefits provided by source control stormwater management tools similar to green roofs at the scale of a drainage basin or jurisdictional watershed that are more cost effective (Carter & Jackson, 2006). Conclusion Stormwater management is important to maintain healthy water flow. As pollutants and flooding are a common issue with stormwater, managing…

The ground is usually saturated and the cool air smells like a mix of wet concrete and sand. That, however, is to be expected through this segment being that it’s a drainage basin. People may tend to feel a bit claustrophobic while travelling through the underpass. After clearing the underpass and moving west, you are greeted by a housing development to the south and rolling prairies to the north. But don’t fret, the feeling…

form part of the Native Americans in the US. The tribe’s main villages were located on the Skykomish River. Primarily, the tribe composed of the Indians of Twana, a community comprising of the Salishan people living in Washington’s Hood Canal drainage basin. The Twana comprised of nine communities, where the Skykomish, also called “people of the big river,” formed the largest group (Pritzker, 201). The area inhabited by the Skykomish tribe comprised of approximately 5, 000 acres of marshy and…
