What Would Happen If Sand Were Water Resistant?

In south Texas there are several types of ecosystems one of those ecosystems are the dunes. South Texas dunes are found along the Texas coastline and the general abiotic conditions are sandy soil, high salt content, some fresh water, flooding in the occasion of severe storms and moisture from rain and waves. Sea Oats and Bitter Pancum are two types of plants that dominate the South Texas dunes. Bitter Pancum adaptation for living in this type of ecosystem is that they are tolerant to high salinity. Sea Oats are less tolerant to high salt but their adaptation is to grow rapidly. Some common animal species that live in the dunes are crabs, which are tolerant to high salt water, gulls, and terns feed on crabs and other species around the

Sand nourishment refers to the replacement of sediment on beaches that has previously been lost, generally through natural processes. It is a commonly used practice in coastal management. Collaroy Beach uses sand nourishment as longshore drift has moved sand, which cannot be replenished as there are rock formations preventing sediment from refilling the beach. Collaroy Beach also does not have an established dune system, and cannot trap sand.

Scientists model the manner in which a liquid wets fibers, gaining useful insights for improving glass wool properties. Sandcastles are a prime example of how adding a small amount of liquid to a granular material changes its characteristics

Areas of water including butts or ponds and sand pits must be securely fenced off or covered.

There are 2 types of beaches. One is erosion dominant and the other is deposition

At Nudgee Beach, erosion was found to have occurred on the edges of the mangrove forest and along the mudflat shorelines. Erosion is typically influenced by natural factors and occurs when pieces of weathered rock or soil are moved – typically by wind and water – from one place to another. Shorelines with lots of sediment and sand are more inclined to be effected by erosional progression. Erosion may also be provoked and accelerated by human interference. For example, if the decision to clear trees and plants from an area is made, erosion is likely to occur as the root systems of plants work to hold the soil in place. If these root systems are removed and erosion does occur, environmental conditions – such as; landslides and flooding – are more likely to take place. Erosion may also cause other plants to tip over, have their underground roots exposed and damaged and contribute to the pollution of local waters; as a result of mud and soil runoff [26]. Erosion at Nudgee Beach was likely to have been influenced by natural factors; however, the development and extension of the Kedron Brook golfing course may contribute to the acceleration of erosional processes and further damage the mangrove

At Wanda Beach, the tall trees and scrubs act as a windbreaker which further protects the sand formation. According to the field work results collected using the anemometer (see figure 3), the Aeolian processes at the front and the top of the primary dune is where the wind speed is highest. So it is important to plant plants such as the hairy spinifex to stabilise the sand due to its expansive root system and its ability to survive low water conditions.

* The sand dunes on the beaches. This area is affected by wind erosion as well as the tides if adequate vegetative cover is not present. The main type of erosion, from the sea, takes the sand from the sand dunes as well as the rest of the beach in a rip. The sand is then pulled out to sea where it forms a sand bar. On calmer days, the sand is brought back to the beach.

Beach nourishment is the physical transfer of sand from an area of excess to where it is being eroded. This often involves dredging and transport of sand by truck or through pipeline. Because of the cost involved, beach nourishment is only used where other strategies prove to be ineffective.

Soil, which is the layer of earth on the top where plants and vegetation grow, contains a pH balance, everything does. The pH, acidity, or alkalinity balance of each type of soil that is being observed can affect the plants, because it determines how many nutrients are being deposited to them. It

Long Island is famous for its sandy ocean beaches. Between the barrier beach and the main coast is the Great South Bay. The beaches and dunes have very different characteristics. The sandy beach is the junction of land and ocean. The sandy beach consists of two zones, the swash zone and the drift line. The swash zone is the area of wet sand, caused by the incoming wave. The drift line is formed by the dead seaweed and other aquatic plants. Behind the sandy beach is the primary dune. The primary dune's main function is to absorb the force of the ocean and protect the great south bay and the island's main coast. In some cases secondary dunes form. These dunes are behind the primary dune and are therefor protected from the ocean. This provides the stability necessary for plant growth. Many time a maritime forests will form on secondary dunes.

In the article, they came up with the idea of gelling agents which is a chemical used to solidify any kind of spilled oil, making it easier to collect. Using the motion of the waves and sea, the gelling agent turns the oil into a rubbery material that can be easily removed from the water with nets, vacuuming, suction, devices or skimmers. This method helps clean the water without taking a lot of the water with it since when it solidifies you just pull out the chunks of oil instead of taking a lot water with it like if you were to try the hay or fleece

The erosion of shorelines is a natural process that can have beneficial or adverse impacts on the creation and maintenance of habitats. Sands and gravels eroded from the shores of coastal bays maintain the beach as a natural barrier between the open water and coastal wetlands. Beaches move back and forth onshore, offshore and along shore with changing wave conditions. The finer-grained silts and clays derived from the erosion of shorelines are sorted and carried as far as the waters of wetlands or tidal flats, where benefits are derived from addition of the new material. However, excessively high sediment loads can smother submerged aquatic vegetation beds, cover shellfish beds and tidal flats, fill in riffle

What is kinetic sand? Kinetic sand is a building toy that can be manipulated into different shapes and sizes. Kinetic sand wasn’t always meant for children. It was originally used for sculpting but now it is often sold as play sand for children. Kinetic sand can be molded, sticks mostly to itself and doesn’t dry out. This is probably why it is popular among children. Kinetic sand is made of sand (98%) and PDMS (2%). Polydimethylsiloxane (PDMS) is one of the popular silicon-based organic polymer. It is used in a variety of products such as, diaper rash cream, hair gels and different types of cosmetics. Kinetic sand itself isn’t in the Wendy’s chicken mcnuggets and french fries but the ingredients to make it is, that would be PDMS. PDMS is also

Significantly, desertification also cause soil erosion, which means soil surface is worn by wind and water. Desertification makes soil easy to erode by water or wind, as soil is exposed and soil structure is instable without forest. LaI R(2003) says that ““Land area globally affected by erosion is 1094 million ha (Mha) by water erosion, of which 751 Mha is severely affected, and 549 Mha by wind erosion, of which 296 Mha is severely affected.” To control soil erosion, an obvious way is virescence, enlarging forest cover, which can protect the soil far from exposing to strong wind. Also, the roots of plants under ground play a role as a framework, as they are obstructions to soil movement,
