Surface water

Discussion: Mudboils cause structural failures since they are suspensions of gravel, clay, silt and fine sand creating an unstable surface. Since the beginning of persistent mudboil activity in the 1970’s, natural landscapes and engineered features have become subject to land-subsidence as mudoils continually deteriorate the areas in their path (Tresohlavy 2003, pp. 27). Petroleum pipeline rerouting, telephone cable burials, and the collapse of bridges have demonstrated the true capabilities of…

Water erosion Water erosion is a natural force that is caused by things like water, ice and wind. This can also happen by human activity. It wears out rocks and soil. Water erosion occurs on streams,rivers banks, sea shores and seaside cliffs. Usually muddy water is a sign of erosion.Usually water erosion happens during rainfalls, snow melts. Runoffs as well because it helps carry away small materials like soil and rocks. There are also more types of erosion like gully erosion and sheet erosion…

Phosphorus is an essential nutrient to all forms of life and is required for building DNA, RNA and amino acids (Paytan, 2011). Phosphorus is often a limiting nutrient in ecosystems, along with nitrogen, and therefore its abundance determines the amount of primary production that can occur within a system (Schindler, 1971). The two main types of phosphorus are inorganic phosphate minerals, such as calcium phosphate rock that is mined for fertilizer, and organic compounds containing phosphorus…

retention and detention ponds hold water and thus reduce peak runoff rates associated with storms, which decreases flood damage. Retention bonds are continuously filled with some volume of water, and this volume fluctuates based on rain events. Constructed wetlands fall under the umbrella of retention basins. These…

Storm water is a large quantity of rain fall or excess water from melted snow or ice. Storm water runoff is the melted ice or snow that flows into the nearest river, creek, lake or ocean instead of being infiltrated into the ground. Storm water management is to lessen as much polluted runoff water flowing back into the nearest body of water. Within in this paper, methods for managing storm water will be issued. Stormwater runoff has been documented to increase flooding which reduces ground water…

The ocean circulation can be defined like the global movement of water, which occurs in the ocean basins. These movement of water are the ocean currents, which plays an important role in the climate since store and distribute heat, microorganisms like nutrients and freshwater all over the world. Therefore, any change that modifies the ocean circulation will alter drastically the global climate. In this section it will be broadly explained the factors, which determine the ocean circulation and a…

According to King County Stormwater Services (2015), stormwater runoff accounts for approximately 1/3 of the water pollution in the Puget Sound. Contaminates like oil, pesticides, soaps, and industrial waste wash in to our local watershed where they negatively impact the local fish population and affect the supporting industry (Narayanan, 2013). Because of the unnatural rate and volume of stormwater flows it can damage wetlands and cause local flooding (Howard, 2007). The Pacific Northwest…

It is a beautiful day in Utah at the Timpanogos Cave National Monument. I have packed a backpack of water, snacks, and a flashlight. After double checking to ensure I have my Cave ticket to tour the inside of the cave, I start the trail. After passing the Visitor’s Center I come to a talus slope. A talus slope is a pile of loose rocks that have collected at the bottom of a mountain, cliff, or any high point. Looking at the walls around the area I can see how erosion has weakened the walls near…

Summary Model Bifenthrin Concentration Prediction The prevalence of bifenthrin in urban Sacramento waters is most likely explained by their wide availability in for the control of ants. Although application amounts reported by professional applicators are not 100 percent correct and that of homeowners are not reported, data from the DPR PUR database indicates that bifenthrin is heavily applied by applicators in urban Sacramento. Additionally, these pyrethroids have a longer half-life than some…

hand, resources depletion refers to the consumption of finite or scarce resources. In a certain sense, pollution is really a type of resource depletion because contamination of air, water or land diminishes their beneficial qualities. There are has several types of pollution. TYPES OF POLLUTION air pollution water pollution land pollution 1. AIR POLLUTION…
