Analyse the impact of implementing rain water harvesting systems on Essay

Analyse the impact of implementing rain water harvesting systems on the stormwater system - Essay Example In Galway, high discharge rates can pose a great impact on both the vegetation and the organism within the ecosystem. This report, therefore, analyzes the impact of rainwater harvesting systems such as cisterns and rain barrels on stormwater as a solution to help reduce the volume of stormwater runoff and prevention of pollution to the existing stormwater. The basic components of residential and small commercial scales are; gutters and downspouts, catchment surface (roof), storage tanks, delivery systems, and water treatment for portable systems (Texas water development board 2005). Field observation is an integral part in the analysis. In analysis, identifying indicators can help in measuring the efficiency of rainwater harvesting techniques. The purpose of the analysis is to determine the amount of surface runoff that comes from each portion of land. The recorded volume from the runoff is then compared to the possible amount of water that could have been collected from the rooftops. The basic method used to calculate the amount of runoff from the structures as well as from the land surface is Q=A x C x I The area (A) in terms of acres was obtained by substitution of determining formulae on the applicable mathematics formulas. The intensity of the rainfall was determined by considering a two year one hour storm. The coefficient of runoff from the site was determined by using the weighted average coefficient. The rational method was employed in calculating the total volume of runoff from the land use. Secondly, the total volume collected from the roof is determined using the rational method. In such a case, the area of the roof represents the area value. The coefficient value of this case was determined to be 0.9. Research has it that the coefficient of the roof surface lies within the range 0.75 to 0.95. This implies that the structures can collect approximately 75-90% of the total amount of

Which is bigger Feel the Fear or The Giant - Essay Example The accurate and appropriate calculations including all the steps of arriving at the right answers are given in the report analysis section (Berry et.al 1995 pp24). The conclusion part will discuss and comment on the results obtained in the entire investigation. Mathematical modelling is the process of using the concepts of mathematics, as well as its language as a system of description (Berry et.al 1995 pp24). A model of mathematics is the idea of representing the relationship between numerous variables that are significant to a given question or problem. The model is used to solving and provide accurate answers to the given problems or situation. The process uses mathematics to solve situations and problems (Berry et.al 1995 pp24). The model guides the solver to find the answers to the questions asked. The modelling is used for a number of aspects including a description of phenomena in the real world, investigation of the observed world and its issues and questions, idea test and predict the real world among others. Questions one and two deals with the calculations of the maximum and the minimum height. The two questions are essential to the report since they determine the achievement of one of the most important research questions. The other questions, i.e. three and four all lie under the same topic of maximization and minimization. Question three finds the area and question four determines the length or the dimensions of the box. To conclude, the investigation gave the results and the data as expected. The mathematical is relevant to the calculations and analysis section of the report. The process of analysis was used in the report to find accurate answers to the mathematical problems in the report. Using the main ideas in the modelling process such as formulation and analyzing among others. The answers found are accurate and gives a general answer to the research questions. They play the analysis part in the report. The answers include the
