If your parking lot is paved with asphalt, and has some cracks in it, you need to understand what is causing the cracks so that you can take the proper treatment steps. Here are the four primary types of cracks that may develop in your parking lot. #1 Edge Cracks Like the name implies, edge cracks develop around the edges of your parking lot. They generally start as very thin hairline cracks and then become wider as they age. They can spread inward from the edges of your parking lot. Edge…

(Overfishing 2012) Salinity is also a major issue. When the water table reaches 1-2 meters below the ground’s surface, the water moves and brings salt with it. As this water evaporates, it leaves the salt within the surface layers of the soil. Over time this causes the soil to become saline and limits the growth of vegetation. Salt sensitive plants begin to die and can leave the soil prone to erosion. High salt content…

more than 100 years ago, its surface drainage system consists of a single surface drainage channel at its downstream basin (Smith et. al., 2005). Whole watershed comprises of about 98% of medium residential settlement and 2% of forest and woody wetlands. Moores Run is accompanied by two USGS stream flow gaging stations; USGS 01585230 at Radecke Avenue and USGS 01585225 at a tributary of Moores Run, near Todd Avenue (Figure 1). Major source of Moores Run flow is the surface run-off during storms.…

Yasmin Bateman Water Essay Why is stormwater pollution a problem and what can YOU do to prevent it? Stormwater is water that surfaces in a large quantity that results from heavy rain. Storm water runoff gathers and conveys litters, animal wastes,dirt and other pollutants as it flows.Storm water pollution is one of the biggest problems in the world today and many animals die or are harmed from it. The polluted stormwater deteriorates our waterways, like rivers , lakes or ponds. There are many…

First, the runoff going into Lake Erie must be reduced. The major area of runoff comes from farms. The cause for runoff is rain and the rain washes away all pesticides, which enter into lakes and rivers: “In both cases, heavy spring rains washed away tons of fertilizer from farms. The runoff drained into rivers that fed the lake. Phosphorus in the fertilizer spurred cyanobacteria growth. Hot summers and other factors made matters worse” (Kowalski 34). As a result of pesticide entering into lakes…

Rain gardens and bioswales are examples of detention ponds. Rain gardens are shallow, vegetated basins that are frequently installed adjacent to impermeable surfaces such as roads, sidewalks, and parking lots. A runoff inlet allows the stormwater to pool in the rain garden and then either slowly infiltrate into the ground or be absorbed by the vegetation (Yang, Dick, McCoy, Phelan, & Grewal, 2013). Bioswales…

the Foxstone Creek in Vienna Virginia. Although there are many different problems that have occurred in this creek, the problem that we noticed that is the most impactful, is the amount of erosion on the creek. Erosion is the process by which the surface of earth is being worn away because of water, ice, wind, waves, and other natural forces. Erosion can also be caused by other things such as, non paved roads, steep slopes, agriculture purposes, and or construction, but we infer that most of…

With the Soviet Union being a major contributor (at the time), the ADF consisted roughly of 80,000 ground and air personnel, and 50,000 conscripts. Its main constituents consisted of 100 antiaircraft-gun battalions, 65 battalions of SA-2 Surface to Air Missiles (SAMs), 60 battalions of SA-3 SAMs, 12 batteries of improved HAWK SAMs (I-HAWK), and 1 battery of Crotale missiles (Air Defense Force). Integration of all radars, missile batteries, air bases, and command centers into an automated…

The probable causes of this phenomenon would obey profound alterations between the atmosphere and ocean, which would be generated in the region of the tropical Pacific, causing abnormalities in the general circulation of the atmosphere with varied effects reverberating globally. The occurrence of this phenomenon results in climate changes, mostly accompanied by abundant rainfall, alterations in marine and terrestrial ecosystems, issue straight influenced and negative impacts on the national…

result of global warming, there is not a corner of the worlds’ oceans left unaffected by anthropogenic disturbances. The heating of Earth’s surface occurs through a life supporting process known as the greenhouse effect. This is a natural process where heat from solar radiation passing through the atmosphere is absorbed by gases and radiated back to the surface (Bradford A 2014). However, human activities, such as deforestation, industrial processes, and fossil fuel combustion are polluting the…
