"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…

My work revolved around the hydrological analysis of the city of Santa Cruz, California area in the San Lorenzo Watershed. My purpose was to determine if any relationship could be discovered between the rainfall and runoff data of the watershed area with the urbanization of the city. The problem at hand was to cross reference the development of Santa Cruz with the patterns of the local water data. Real precipitation and stream flow data within the San Lorenzo Watershed where studied from January…

Storm water pollution is a huge problem in Georgia. It can lead to sickened animals and polluted waterways. Storm water itself isn’t deadly though. It is what is in the storm water that can be. I will explain exactly storm water pollution is and how it can be prevented. Storm water is the water that falls from a storm and onto the ground. Like I said before, storm water itself isn’t harmful. But when pollution from the ground and other such areas mix in with the water it can become deadly.…

local streams, rivers, and waterways by curbing runoff thereby reducing the level of runoff that reach the river, according to the website potomac.org*. This law made is possible for Maryland to collect a fee, based on the amount of paved or hardened surfaces on a property that collects pollution, from the community which they then used to fund local waterway clean-up efforts. (Potomac.org) These efforts have led to reduced pollution in the…

the volume of water is unable to seep in to the ground efficiently and runoff is created. Runoff is when the water travels across the ground surface and flows in to storm drains, streams, or other direct routes to significant water sources. As researchers May, Horner, Karr, Mar, and Welch state, urban development increases the amount of impervious surfaces which, while it does not contribute to pollution, alters the physical behavior of water systems (May, Horner, Karr, Mar, & Welch, 1997).…

Steps I would take to evaluate the land conditions is to analyze and determine the main causes of the issue at hand by determining the causes of the degrading over overgrazing and invasive weeds that are replacing native grasses. By doing this we can analyze the causes of grazing by ranchers and study how restoring these lands through the restoration process that can be used in order to provide a positive effects and outlook on the environment. Some approaches we can take when evaluating…

s from all the surfaces to ensure complete polymerization. Before placing the final increment a transparent matrix band was used to contour the restoration. The restoration surfaces were polished using a sand paper disc. The root apices were sealed using composite and the entire teeth except the bonded interface and 1mm on the teeth surfaces next to the interface were coated with two layers of nail…

The need for agricultural resources is as old as American itself. Since our arrival and birth of our great nation, man has had a need for cheap, durable sustenance that could be produced locally and efficiently. With the expansion of our nation, so has the expansion of supply and demand for agricultural consumer goods, which led to technological advancements to mass produce and shipment. It was not noticed that this drive for agricultural needs would have a devastating impact on the environment…

Fig. 6 shows the results of air permeability, total water absorption, and voids. R mortars had lower permeability than the mortars with WTS. Air permeability of R was 1.13 x 10-13 m², a value 5 times higher than L60. The air permeability increased with increasing WTS content. The water absorption values ranged from 10.6% to 13.7%, and the voids from 9.6% to 12%. The results show that WTS replacement increased the porosity and permeability of geopolymer mortars. The geopolymer binders with WTS…
