Fraser Lowland
The Fraser Lowland is a landform and physiographic region in the Pacific Northwest of North America, shared between the Canadian province of British Columbia and the U.S. state of Washington. The region includes much of the Lower Mainland region of British Columbia, and the coastal plains of Washington's Whatcom County. As a physiographic region, the Fraser Lowland is part of the Georgia Depression, which in turn is part of the Coastal Trough.''Landforms of British Columbia: A Physiographic Outline'', by S.

Landsat
The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. The most recent, Landsat 9, was launched on 27 September 2021. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance and education, and can be viewed through the U.S. Geological Survey (USGS) "EarthExplorer" website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from ; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading. Each Landsat scene is about 115 miles long and 115 miles wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coastal Plain
A coastal plain is flat, low-lying land adjacent to a sea coast. A fall line commonly marks the border between a coastal plain and a piedmont area. Some of the largest coastal plains are in Alaska and the southeastern United States. The Gulf Coastal Plain of North America extends northwards from the Gulf of Mexico along the Lower Mississippi River to the Ohio River, which is a distance of about . The Atlantic Coastal Plain runs from the New York Bight to Florida. The Coastal Plains of India lie on either side of the Deccan Plateau, along the western and eastern coasts of India. They extend for about 6,150 km from the Rann of Kutch in the west to West Bengal in the east. They are broadly divided into the Western Coastal Plains and the Eastern Coastal Plains. The two coastal plains meet at Kanyakumari, the southernmost tip of the Indian mainland. The eastern coastal plain is located between The Bay of Bengal and the eastern Ghats and the western coastal plain is located betwe ...

Nooksack Valley
The Nooksack Valley refers the collection of mountain valleys within the North Cascades centered around Mount Shuksan, Mount Baker and the Twin Sisters, formed by the catchments of the upper Nooksack River and its alpine tributaries (primarily the North Fork, Middle Fork and South Fork). Roughly covering the western half of Washington state's Whatcom County and a small northern fringe of Skagit County, the Nooksack valleys expands between the Sumas Mountain and Stewart Mountain (between which the valley ''proper'' is located) to the west; the Red Mountain, Church Mountain and Goat Mountain in the north; the Ruth Mountain, Icy Peak and Nooksack Cirque in the east; and the Lyman Hill and Mount Josephine in the south. Out of the three main tributary valleys, the North Fork Valley communicates with the Columbia Valley in the north via a decently wide mountain pass between the Sumas and Red Mountain, where the Washington State Route 547 goes through from Kendall to Peacef ...

Canada–United States Border
The border between Canada and the United States is the longest international border in the world. The terrestrial boundary (including boundaries in the Great Lakes, Atlantic, and Pacific coasts) is long. The land border has two sections: Canada's border with the contiguous United States to its south, and with the U.S. state of Alaska to its west. The bi-national International Boundary Commission deals with matters relating to marking and maintaining the boundary, and the International Joint Commission deals with issues concerning boundary waters. The agencies currently responsible for facilitating legal passage through the international boundary are the Canada Border Services Agency (CBSA) and U.S. Customs and Border Protection (CBP). History 18th century The Treaty of Paris of 1783 ended the American Revolutionary War between Great Britain and the United States. In the second article of the Treaty, the parties agreed on all boundaries of the United States, including, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nooksack River
The Nooksack River is a river in western Whatcom County of the northwestern U.S. state of Washington, draining extensive valley systems within the North Cascades around Mount Shuksan, Mount Baker and the Twin Sisters, and a portion of Fraser Lowland south of the Canada–United States border. The river ''proper'' begins with the merging of three main tributaries, namely the North Fork, Middle Fork and South Fork, near Deming. All three forks originate in the Mount Baker Wilderness, and the North Fork, the longest of the three, is sometimes considered the main river. The Nooksack is approximately in total length measuring from the North Fork headwaters. The lower Nooksack flows as a northerly loop through the fertile southern Fraser Lowland agricultural area before emptying into Bellingham Bay and, via the Strait of Juan de Fuca and the Strait of Georgia, communicating with the Pacific Ocean.

River System
In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin. They are governed by the topography of land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land. Geomorphologists and hydrologists often view streams as part of drainage basins (and tributary, sub-basins). This is the Topography, topographic region from which a stream receives Surface runoff, runoff, throughflow, and its saturated equivalent, groundwater flow. The number, size, and shape of the drainage basins varies and the larger and more detailed the topographic map, the more information is available. Drainage patterns Per the lie of Channel (geography), channels, drainage systems can fall into one of several categories, known as drainage patterns. These depend on the topography and geology of the land. All forms of transitions can occur between parallel, dendritic, and trellis patter ...

Sumas River
The Sumas River is a river in the Fraser Lowland and a tributary of the Fraser River system, coursing across the international border between the Canadian province of British Columbia and the U.S. state of Washington. Course The Sumas River originates in the Sumas Mountain (American Sumas) in Whatcom County, Washington, with its tributary creeks draining the mountain's western and northern slopes. These headwaters confluence west of the mountain just north of Lawrence where the nearby Nooksack River exits the Nooksack Valley, and the resultant river then flows north first past Nooksack before coursing generally northeast past the town of Sumas (where it picks up Johnson Creek, the first of its only two left tributaries) and crosses the Canada–United States border. The Sumas River then runs further northeast, crosses the Trans-Canada Highway near Kilgard (where it picks up Marshall Creek, the second of its only two left tributaries) and reaches the southeastern side of a mount ...

Catchment
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the ''drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coquitlam River
The Coquitlam River ( /koʊˈkwɪtləm/ or /kəˈkwɪtləm/) is a tributary of the Fraser River in the Canadian province of British Columbia. The river's name comes from the word Kʷikʷəƛ̓əm which translates to "Red fish up the river". The name is a reference to a sockeye salmon species that once occupied the river's waters. The river is an 18 km meandering river with 30 tributaries and various morphological features. Owing to the size and area of its location, the river has a history of disastrous floods.G3 Consulting Ltd. (G3). 2016. COQMON#8 Lower Coquitlam River Substrate Quality Assessment (2012-2015).

Pitt River
The Pitt River in British Columbia, Canada is a large tributary of the Fraser River, entering it a few miles upstream from New Westminster and about 25 km ESE of Downtown Vancouver. The river, which begins in the Garibaldi Ranges of the Coast Mountains, is in two sections above and below Pitt Lake and flows on a generally southernly course. Pitt Lake and the lower Pitt River are tidal in nature as the Fraser's mouth is only a few miles downstream from their confluence. The river was named for William Pitt the Younger. The first mention of the name, as "Pitts River", occurs in the 1827 journal kept by James McMillan of the Hudson's Bay Company. The river has an alternate name, Quoitle, which is probably equivalent to Kwantlen. East of the lower Pitt River, 20 km long, is the community of Pitt Meadows, while to its west are the cities of Coquitlam and Port Coquitlam; opposite its mouth is Surrey. Port Coquitlam and Pitt Meadows are connected by the Highway 7 brid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
