Wetland Destruction Wetlands are very important to the ecosystem and human communities. They filter pollution‚ provide habitat for countless species‚ endangered plants and provide natural flood protection. In the 1600s more than 220 million acres of wetlands existed. Due to farming and development‚ by 1980 more than half of those had been destroyed. Wetland destruction is becoming a huge problem. Not only are wetlands disappearing but those still existing are suffering degradation from chemical

Gunite and vinyl liner pools are the two most common types of inground pool construction in the northeastern states and both are good options. There are some major differences between them‚ in terms of construction‚ durability and maintenance. Getting all the information can help you make the wisest choice‚ so let’s look at some particulars about each type. Gunite Pools Gunite pools are created using steel rebar coated with an application of concrete to make the shell for the pool. It must meet

River velocity Measuring the velocity allows us to determine the speed‚ at which the river travels. If a high quantity of rain falls close to the source of the river there will be a greater amount of water travelling down stream and as a result the volume of water will be travelling at a higher speed. In the section of the river harbourne that that this measurement was taken in a high river velocity can indicate that Harbertonford is susceptible to flooding‚ a hazard that the flood defences

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

Aversion to Diversion Discussion Chapter four‚ Aversion to Diversion discussed the idea of diversion in the water system many project through out the the 60’s-90’s were proposed; one of the most daring engineering schemes ever in regards to water. The chapter touched on damming the canyon‚ the north American water and power alliance‚ and different regulations put in place for this proposed plan. It Also discussed the pros and cons to damming the canyon in which the cons outweighed the pros. There

When our minds are opened to the windows of what the artist or creator wanted us to see‚ we are able to learn more about the artwork in itself and ourselves as well; moreover‚ our minds become open to how the artwork affects us on an emotional and a physical level. 2. We are able to understand
