To what extent are floods necessary for the formation of river landforms? River landforms are formed by either depositional methods or erosional methods‚ and the landforms that floods are necessary for are formed by depositional methods‚ but there are landforms that are formed by erosional methods where floods are not needed to create these landforms. The main landforms that are formed by floods are levees‚ floodplains and oxbow lakes. The most obvious example of a landform where

Problem-solving: Flooding I think that the best solution from the Environment Agency is the Upstream Flood Storage. I think this would be the best option because it will stop the town from getting flooded but also‚ it would be better downstream. The water will be temporarily stored on fields upstream of the town‚ on farm land. There may be animals on the fields but they can easily be moved out of the way. This could also lead to new wildlife in the area‚ although also disrupt the wildlife already

Hurricane Katrina carries a great impact on the lives of American as well as the view of infrastructure and engineering in the public mindset. If you ask the general public what lead to the demise of New Orleans back in 2005 many will say it was the failed levees that left Louisiana and the 9th District underwater and cost the lives of innocent people who believed they were safe. But why did these levees fail? What could have been done from an engineering standpoint to fix these levees and perhaps

Hoover Dam Bypass: The Mike O’Callaghan-Pat Tillman Memorial Bridge The bridge was built to be take the traffic away from the Hoover Dam which had just turned 75 years old and cannot hold the traffic anymore. The Hoover Dam was not able to hold the 14‚000 thousand cars that drive across the dam every day. To help preserve the dam Arizona and Nevada built The Mike O’Callaghan-Pat Tillman Memorial Bridge. This was a huge project between both states that would end up cost them $240 million. The

Sand Dams in Kenya WHAT IS A SAND DAM? A Sand Dam is a steel reinforced concrete wall built across a sandy riverbed. During rainy seasons‚ a seasonal river forms and carries soil (consisting of sand and silt) which moves downstream. The heavy sand builds up behind the dam‚ whereas lighter sand and silt washes over the wall of the dam. Within the space of one to four rainy seasons‚ these dam types get completely filled with sand. However‚ approximately 40% of the volume held behind the dam is

year from landslides in the United States. Examples Vaiont‚ Italy‚ 1963 One of the world’s highest arch dams was built in Vaiont‚ Italy in 1960. Three years later‚ at 10:41 pm on the night of 9th October‚ millions of tons of rock slid down from Mount Toc into the Vaiont reservoir. It went across the reservoir and came back and made a 100-metre high wave. The wave went over the 262-metre high dam and into the valley below.
