Stream Restoration Essay examples

In 1935 the Hoover Dam was completed forming Lake Mead, providing flood control, reservoir storage, power generation and regulates the downstream flow to the Lower Basin States. [footnoteRef:20] In 1963, the Glen Canyon Dam was completed forming Lake Powell, providing the Upper Basin States with enough reserve capacity to allow them to meet their annual obligation of 7.5 Million Acre Feet (MAF) to the Lower Basin States, allowing the Lower Basin States to use the allocation.[footnoteRef:21] As a consequence of the construction of the Hoover Dam and the Glen Canyon Dam, the Colorado?s flow often evaporated in Mexican sands close to the Delta.[footnoteRef:22] Around the 1970s, the Cienega de Santa Clara had shrunken by 500 acres. Nevertheless, due to the following wet decades, the Cienega was resuscitated to about 10% of its original acreage in the 80?s and 90?s.[footnoteRef:23] Currently, the Cienega is a 40,000 acre wetland that exists due to the return flows from the Mohawk Irrigation and Drainage District near Yuma, Arizona.[footnoteRef:24] This Cienega is the home of less than 100 members of the Cucapa tribe and is the habitat of several endangered fish and birds, including Desert Pupfish and Yuma Clapper Rail.[footnoteRef:25] [19: D.F.

Dams built for flood control and water catchment along the rivers leading to these coasts inhibit the transport of large grained

The Ellicott City flood was destructive because it was on a high gradient stream. The high gradient stream made it flood faster, and had low stream discharge. Discharge is cross section of stream channel. It was also capable of moving large particles, which is an example of deposition and erosion. In the experiment, the ‘Main Street Ellicott City’ stream was more affected than the Meandering Stream. The Main Street Ellicott City stream was flooded faster, and more houses and cars were destroyed compared to the Meandering

In 1992, The Elwha River Ecosystem and Fisheries Restoration Act of 1992 authorized the US Federal Government to acquire the hydroelectric power projects of Elwha Dam and Glines Canyon Dam, where are located on the Washington State for demolition for habitat restoration and decommissioning. The dam removals began in 2011 and finished in 2014. I wondering that why government decided to remove the dam and what happens in Elwha River after dam removal. In this paper, I write about the following topics: main purpose of the Elwha and Gliens Canyon dam, effects to the Elwha River as well as ecosystem after constructing dam, reasons of the dam removal, process of the dam removal, and effects after dam removal.

The levee system has disrupted the natural deposits that are left from the overflow of the river.2

The economy is, or was, expected to grow, along with the salmon population and recreation. The observers, McEwen and Weintraub, studied the plan for restoration and the river before the plan, made presumptions with the information given to them. The San Joaquin’s restoration plan, as expected, contained more consequences than lifesavers. In the end, dams, since they are made by humans, are a disruption to wildlife, just as humans

The buffer can filter out the stuff we put in our lawns, stop the silt that washes off places where we dig and contain pollutants from lawns and roads. These pollutants have another way to get in to the Chattahoochee, they flow virtually unchecked into the river from hundreds of miles of creeks that thread through the water shed. Silt is sent down stream because of nearby construction. The greatest danger to the creeks and to the water shed is land disturbing activities that lead to erosion, whether it is tearing out plants and trees along the banks or lack of fence systems to hold dirt. Local governments over seen by the state authority boards are responsible for enforcing state laws on erosion control. But when faced with the pressure and desire to increase tax, few local governments stand in the way of development. Even the latest growing counties have at most a few people to enforce the law. Donald Mitchell, chief soil and erosion inspector in Fulton Count, compares his job to "dropping a bucket of golf balls on a driveway and having to pick 'em up before they hit the street." His job is part cop and part educator. He needs to make sure everyone is educated on the issue so that people know what to do. Erosion into the creeks that feed the Chattahoochee is even more severe a problem than direct run-off into the river, as

In an attempt to combat erosion and interest more people in visiting this area an ongoing project has been implemented along Long Beach and Nutgrove Beach. The project aims to reduce the rate of erosion and make the area a desirable place for people to visit for many years to come. One of the most recent additions

The removal method of Ringed Crayfish data collection was over a sample site area of 50m2 at Pearson Creek, a stream, containing a density of 5.18 crayfish/m2. The sample site was collected in 5m in width by 10m in height with wet, rocky, and grassy conditions. The data collection incorporated five different samples of the number of crayfish removed from the stream each time (Figure 1). Sample one caught 53 Ringed Crayfish with 0 crayfish caught prior. Sample two caught 37 Ringed Crayfish with 53 crayfish caught prior. Sample three caught 42 Ringed Crayfish with 90 crayfish caught prior. Sample four caught 26 Ringed Crayfish with 132 crayfish caught prior. Sample five caught 18 Ringed Crayfish with 158 crayfish caught prior. What was caught in the previous sample was added into the total amount of crayfish caught prior. A negative linear relationship is displayed by data collected in Figure

Located near Cowan, Pennsylvania, Conley Run is a tributary of Buffalo Creek that has experienced severe degradation due to agricultural activity. Specifically, the deposition of large amounts of animal wastes, pesticides, and fertilizers has resulted in significant eutrophication throughout the stream. Furthermore, bank degradation associated with the movement of livestock has caused the displacement of foreign sediments into stream habitats. These factors, among many others, have caused the lake to be considered “impaired” by PA-DEP. In response, the Buffalo Creek Watershed Alliance, the the Union County Conservation District, and the Department of Environmental Protection and Fish and Boat Commision have partnered in an effort to restore stream habitat and create a riparian buffer to protect the stream.

The Herring River Restoration Project in Cape Cod, Massachusetts is the largest saltwater restoration project of the east coast. It involves many organizations’ support through research and grants to be successful such as Friends of Herring River, The Cape Cod National Seashore, US Fish and Wildlife Service, as well as various other private and governmental organizations. The Herring River Restoration Project centers on the deteriorating dike that was put in place in 1909 which forever changed the original undisturbed ecological dynamic of the Herring River system.

Robinson’s restoration reach is approximately 2.4 km long and is located 16 km downstream of Crocker-Huffman Dam. The project included a very complex suite of actions to restore Robinson’s reach which was degraded as a result of mining activities and recent flood impacts. Channel reconfiguration and the creation of a large floodplain with native vegetation increased the river channel’s ability to transport and deposit sediments under the river’s current flow regime; hence improving channel dynamics and salmon passage concerns. These actions within the channel produced improvements for salmon spawning and rearing through the creation of

Over the last few decades, the loss of Louisiana’s coastal wetlands has become a point of concern because of the vital roles the wetlands play in the environment. They have been destroyed over time because of natural causes such as hurricanes and weather as well as from the construction of man-made flood-control levees. Wetlands serve many purposes within the environment. Not only do the wetlands effect the residents of southern Louisiana, but they effect the animals that call the wetlands home as well as the industries that thrive off the wetlands. Since the wetlands have begun to disappear, steps have been taken in order to prevent Louisiana’s wetlands from disappearing. Restoration acts have been put in to place by the government to help

Daniel Weintraub in the article , River Restoration Project Offers a Sprinkling of Hope , claims that the San Joaquin River restoration will begin in earnest thanks to changes in federal laws . Weintraub supports his claim by telling us that the new river will flow in parts that have been dry for decades , it will also provide fresh water to the Delta. The author’s purpose is to state that the newly restored river will bring back fish and help all kinds of endangered species. The author writes in an informative to for the readers.

On Saluda Avenue, in Columbia, South Carolina, there is a streambank that is being eroded at the base, making the land unsafe and unprotected. We have been asked to find a solution to the stream bank erosion and wall repair. As you have seen above we have done plenty of research and we think our solution to the problem is the best answer. The best way that we choose is gabion stone method for stream bank erosion. We will design a box or any shape needed to fix the wall out of the chicken wire. Then we can fill the chicken wire full of different irregular shaped rocks that fill the entire box of chicken wire. Once we have placed the gabion in its place the small spaces in between the rocks will then be filled with the sediment that is
