Surface runoff

Surface Runoff Introduction In the experiment taken place a group of three to four of use wanted to test the effects of what multiple chemicals had on Lemna minor. This is also known as duckweed. The chemicals we tested all are harmful, as they do not treat the life cycle of these plants well being in their water. What is Lemna Minor you may ask well stated above it is also known as duckweed but more information helps you know that it is found in ponds and it grows at a rapid rate according to the (USDA.) Lemna Minor is also a summer plant so in the winter months of cold areas you would not find it. The goal of our experiment is to find out what winter chemicals and deicers cause a problem with the Lemna Minor when the salt and chemicals are washed off the road and into our water ways. The group tasted not only a controlled environment sample, but also tasted a sample with miracle growth to see the affects. In our experiment however we did not follow the proper measurement of what the ratio calls for by the labeling and the chart given to us by their website. We over supplied the plants to see how it would be effect in…

with turbidity. The interference with turbidity can reduce photosynthesis and decrease primary productivity which the fish food organisms depend. Fish production is reduced as a consequence. (“Water Turbidity Effects on Fish and Aquatic Life | Learn Water Basics Students Teachers Public”) Turbidity (cloudiness of water) should at no time go above 5 nephelometric units. Turbidity can go no higher than 1 NTU in at least 95 percent of the daily samples for two consecutive months. The website does…

There have been many soil conservation measures that have been either recommended by agricultural agencies or demonstrated by top-down government. Farmers need to make trenches so water runoff will get out of the crops or they will damage. Most farmers do not do that. Conservative farming techniques can contribute to soil conservation and increase crop yields. There is a need to systematically understand the rationality and effectiveness of these measures to enhance a broader scale 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…

heavy rainfall events because of its impermeable surfaces (G. E. Hollis). By recording the discharge in a catchment the data can be used to create a hydrograph. It is often useful to analyse a hydrograph because it shows how quickly rainwater moves to the stream channel (Holden J. 2012.) The aim of this study is to compare an urban and rural catchment, and to find out why they are different. To achieve this a model was used to simulate both catchments, and an accurate hydrograph for those two…

But one of the things that I learned more about was the problem with surface runoff of fertilizers and how it interacts with herbicides. The lab showed the participants on a small scale how eutrophication occurs and how it doesn't take a long time for algae to take over an area. Nitrogen and Phosphorus are usually found in fertilizers but not always at the same time. A study done said “ Concentrations of phosphorus and nitrogen in surface waters are being regulated in the United States and…

to be an exposure a receptor, an individual or population, must come into contact with the environmental medium (Simon, 2014). The environmental mediums are soil, water, air, and biota. The concentration of the pesticide present must be determined in order to calculate a dose. Also, with each individual medium there will be a level of variability and uncertainty that must be considered. Contamination concentrations in the soil will be highly variable. This is due to the application of the…

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…

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…

"Stormwater a sloppy slope" by: Ethan Crowe When you think of rain you think of a saving grace from the harsh heat of summer, or you might think of a fun time to play around outside. Sadly that time might come to an end. Storm water in the past might have been safe and slightly clean in the past but nowadays it causes many problems in our society. This paper will explain how and why it harms this society and how to prevent it. One of the main reasons storm water is harmful is the air…
