Delta Wetlands

A wetland is a place with hydric soils that has been saturated by water for a minimum of 14 days during the growing season. Common names for a wetland are a swamp, bog, or marsh.

Silver Creek Wetland Complex is a rare coastal wetland found along the eastern side of the Nottawasaga Bay Shoreline. It falls within the town boundary of the Town of Collingwood, which was formally a part of the Town of Blue Mountains. Because the area is a part of the greater Silver Creek Watershed, the marshy land is classified as a Schedule B Category 1 land under Environmental Protection as per the Official Plan of the Town of Collingwood. Blue Mountain Trust Watershed Practice monitors the watershed and the significant wetland is protected and maintained by Nottawasaga Valley Conservation Authority. The 2700 Ha watershed flows through the “Lake of Clouds” by Castle Glen, down the Niagara Escarpment, where the 160 Ha complex at the

Some amount of natural erosion is necessary to provide the sediment for beaches in estuaries and coastal bays. However, excessive erosion has occurred in the past due to development. Industrial and private development along the world’s coastlines has increased dramatically since the 1970s (Nepf). Developers and builders completed much of this construction without taking into account the effects of coastal erosion. New buildings were often placed too close to the existing shoreline so that

Giving full credit to restricting the Mississippi River as the culprit for loss of wetlands is not accurate. The booming oil and gas exploration of the 1970’s and 1980’s merits a name on the marquee as well. The pipelines and canals used to transport the resources to the outside world placed a great deal of stress on the fragile wetlands. Erosion from the barges in and out of the marshes as well as the salt water allowed into the fresh water, providing a precarious habitat for fresh water species – flora and fauna alike. Plants provide root systems to hold soil in place. Fish and fowl provide an economy for the area. Enter

The discharge of the Mississippi River is around 200 and 700 thousand cubic feet per second and drops within 45 million metric tons of sediment per year. However, the amount of sediment discharge is alarming since it was 400 million metric tons of sediment per year in the 1900s. This discharge of sediment is largely on the Mississippi River delta, however, the modification with damns, wing dikes, artificial lakes, levees and others causes the sediment to settle earlier in the river instead of discharging it into the Mississippi River Delta. Before the Delta was growing, but now it is damaged and

It is also notable that while this response is clearly evident on the barrier coast, waves and surge show considerably more inundation for the 1990s scenario when compared to that of 1950 along the bay marsh shorelines and farther inland” . The loss of the barrier was directly and indirectly altered by human activities. Within the past 40 years, barrier islands and marshes have drastically diminished along the coast and are projected to continue to do so without a major restoration

An up-to-date survey of the entire property which shows the existing improvements and the location of all wetlands and poorly and very poorly drained soils (including wetland flag numbers), wetland buffer, and 12’ primary structure setback from the buffer edge. The survey should be prepared by a licensed surveyor. For properties where the wetland delineation is older than 3 years, the professional who did the original delineation should reconfirm the accuracy of the boundaries in writing as part of the application. The Conservation Commission reserves the right to request documentation/notes for any wetlands delineation.

The coastal wetlands of the Mississippi River Delta ecosystem which contains almost forty percent of the coastal wetlands of the 48 lower United States is of special concern because of the economically and environmentally important services which they supply to the northern Gulf of Mexico and also to the entire United States. Ecosystem services such as storm production, water quality enhancement, faunal support and carbon sequestration are provided by these coastal wetlands. Approximately thirty percent of the US commercial fishery would depend on the wetlands and ironically they protect an oil and gas supply and fifty percent of the nation’s refining capacity. Eleven workers were killed and seventeen people were injured. Millions of gallons

The Mississippi river is over 1,000,000,000 years old there have been many variations of travel and transportation of goods through this river by the natives and all kinds of people. The boats and other transportation crafts could move sediment from spot to spot and causing it to build up in certain areas and even block up some little creeks that feed off the river. The sediment that the boats would push up on the bank of the river when they went to land could also cause the land around the river to raise which would eventually cause the river to get shallower or deeper in certain spots. Could also cause the plain around the river to raise because of the

The Riparian Zone that was investigated was behind the schools agriculture. The river was going downstream which is to the west, there are also factories to the west and they do not affect the area I will

At the coast, scientists observed a massive expansion of the river mouth delta during the second year of dam removal. At that time, wave-breaking zone of the river mouth was moved over 200 m toward the offshore direction. During the second year of dam removal, detailed coastal surveys said that this expansion deposited about 2.2 million cubic meter (about 3.3 million tons) of sediment. Although most of the sediment was gravel and sand, a broad patch of mud was covered the seafloor from 0–2 km west of the river mouth. Researchers observed a secondary region of sand deposition in the place in 0–5 m water depths from about 1.5 km east of the river mouth. The sediment was 1–2 m thick, and it came from eastward transport of sediment which was deposited initially offshore of the river mouth (Warrick, 2015).

Conventional waste treatment plants, Living Machines and constructed wetlands can all be used for water purification, but only living machines and constructed wetlands will provide us with a sustainable future.

A coastal saltwater marsh is an ecosystem daily flooded by tides, and mostly consists of mud. They are usually located in the in the upper foreshore (seashore) area between land and brackish water in stable temperatures and high latitude locations. The area is flooded every day, delivering sediments, nutrients, and water. The plants that live in this region often trap sediments. Since they have daily access to nutrients, the marshes are involved in the delivery of nutrients to coastal regions and support a large portion of aquatic organisms’ food web. However, only plants and animals accustomed to high salt concentrations (3.5% salt) such as herbs, grasses, shrubs, fish, and crabs can live in these marshes. Some abiotic factors that affect

The boy sat down on the beach. He looked around only to see a blue blanket. The large waves crashed on the ground, and he stood up. His sharp and spiky hair stroked a plan tree. He turned around to see a invisible thread on his face. He looked closer, and the sun light reflected of the thread. The thread felt like silk, as he slowly passed through it. In confusion he turned around to see what it really was. He looked around and saw a big black block. The black block had several dots on its face. The long legs swooped down the invincible thread. The boy walked away. His cut pants stroked the ground. The block moved back into the thread. Then he stubbled backwards on his feet. His eyes strained. He stood up slowly,and jumped backwards. He looked at the large block, and then walked away. He again sat down on the beach. The sparkling sand glistened in the sun. The blue tropical ocean had large reefs. The tiny fish swam under the large ocean arks. Blue, red, green, and yellow fish swam past each other grouping as they go.

Wetlands play a major role in the ecosystem as the provides habitats for animals as well as purify water and our wetland at Reddam House acts as a purification for water that passes it as well as a habitat for many birds and insects.
