Response surface methodology

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…

your body just went through a response known as the fight or flight response also known as the acute stress response. The fight or flight response evolved as a mechanism enabling humans and other mammals to react quickly to potentially life-threatening dangers. The sequence of physiological response and hormonal changes allows for someone to choose between fleeing to safety and fighting off the threat. The body is very sensitive, however, and oftentimes the response is triggered by stressors…

The book The Glass Castle by Jeanette Walls has left a great impact on me because I feel a few of Jeanette 's many problems she went through during her younger life is somewhat similar to what I have gone through. Not many people know about my life at home but this quote from the The Glass Castle I think accurately states the kind of life I am living and how Jeanette’s life is similar to mine,“I wanted to let the world know that no one had a perfect life, that even the people who seemed to have…

The length of time that people know someone tends to be a justified reason that they can trust that person. This scenario tends to occur in close or life-lasting relationships. These particular companions recognize their friend for who they are, as well as the friend that they once were (Pearson). Dr. Irene Levine, suggests that having a mutual history together enables them to express themselves more comfortably to one another. They may have also taken part of other meaningful experiences in…
