Do the coastal defences at Dawlish Warren have a significantly larger impact on coastal processes than at Slapton Sands? Throughout this independent enquiry I will be examining the structure and location of the majority of the coastal defences at two drift aligned depositional landforms on the South Devon coastline; Dawlish Warren (the geographer online)1 and Slapton Sands (Chadwick et al, 2005)2. In particular, the success of the defences placed at these two landforms will be compared by…

The Biggest Project in Yuma. Irrigation is the process by which a water supply is brought to the land or crops to aid its growth, and to do so channels are usually used. The yuma project was designed to irrigate Yuma County Arizona And part of California and thus to exploit to the maximum the agricultural activities of the place using as main source of water the Colorado River. The project began in the year of 1903 and with the a series of geographic, environmental and logistical challenges…

How is michigan trying to stop the spread? Well, since 1993, ships who travel from ocean-to-ocean, have been required to replace their ballast water with ocean water before entering the Great Lakes(National Wildlife Federation). This proves that people are trying to eliminate the spread of invasives, and that this is a big issue. This process is known as ballast water exchange. Unfortunately, it doesn’t fully eliminate all of the estimated 160 new invasive species, carried over to the Great…

Coal has been used for far longer than one might think. Being traced to as far back as 1,000 B.C. One might ask, what is coal? Coal started forming millions of years ago as plants and animals would die. Over a long period of time rocks, dirt, and sediment pile on top of the decaying material, creating high pressure and heat underground (Society). It has been known to be found up to 1,000 feet below the surface. This type of coal, which has undergone the longest period of carbonization, is called…

Arthropods are made up mostly of crustacean about 50,000 known and divided into groups; Branchiopods, Maxillopods, Malacostraca and Ostracods. The Malacostraca is divided into five different groups, decapods, stomatopods, euphausiids, amphipod and isopods. Decapods include crabs, lobster and shrimp it’s the largest species. Decapod means ten to five pairs of legs most first pair are modified as large claws, called chelipeds. Most decapods hatch as a zoea but on some occasion shrimp can hatch a…

“ring” like bells（1）, not all of them endless displays of wildflowers (2), change into different colors, sometimes appears as veins of brown and red throughout the rock, and how it forms are considered as the ringing rock’s four mystery natures from now and on. It was said ,Ringing Rocks Park that situated near the small Delaware River community of Upper Black Eddy possesses this “ringing” quality,was the largest boulder field in Pennsylvania . The ring human can hear is not the first sound, but…

Iaccarino et al. [11] investigated effectiveness and safety of belimumab with a prospective cohort study. All 67 patients were required to fulfill the 1982 ACR revised criteria for SLE and have active/refractory disease manifestations, detectable anti-dsDNA antibodies and low C3 or C4 serum levels; exclusion criteria were severe lupus nephritis (proteinuria > 6 g/24 h or creatinine > 2 mg/dl), severe active neuropsychiatric lupus, potentially life-threatening SLE manifestations and ongoing…

In the world richest biotope, wetlands, and specially floodplains, remain particularly active zones in terms of nutrients, biodiversity, flows spreading, sediment transfer and human activities. Today, these sensitive zones are facing increasing human pressures and augmentation in frequency and intensity of extreme hydrological events. The impact of such extreme events on floodplain ecology and biogeochemistry is still difficult to assess. In this context, hydrodynamic models are attractive tools…

Intro: Arizona has had a huge amount of change throughout the years especially with agriculture. One thing that stands out would be the evolution of irrigation, especially in Yuma arizona. Yuma arizona has gone from having little to no adequate irrigation to being one of the most successful irrigated farm lands in the country. With having the colorado at Yuma’s disposal, it wouldn’t be an injustice to utilize the river for irrigation. It also helps having tremendously fertile land so that we can…

Plastic water line is lighter and easier to work with as well as cheaper. These new plastic water lines also have a high life expectancy and a low corrosion rate. Plastic pipe does not collect the sediment on the pipe like cast and ductile. This is because of the low friction in the pipe between the water and pipe. Plastic pipe keeps water flowing without bursts, flooding, or disruptions. There are four different types of plastic water main you can…
