Richter magnitude scale

al., 2000). The importance of a river’s flow regime for sustaining biodiversity and ecological integrity has been well studied over the last past 4 decades. These studies have characterized flow regimes on a regional and global scale to understand the hydrologic magnitude, frequency, and timing of flow to develop general guiding principles for management. The development of flow assessment methodologies is used for prescribing environmental flow requirements. Environmental flow regimes in…

Hydraulic fracturing, also known simply as fracking, is a process used to extract natural gas and oil from beneath the earth’s surface. This process is accomplished by drilling a well and pumping pressurized water, proppants such as sand, and chemicals into that well; the result of this process is that fractures occur within the targeted layer of shale rock, which allow for extraction of the desired gas and oil (Hyder and Lerner 2250). As a cleaner burning fuel, natural gas continues to be an…
