Development of an Equation to Estimate the Monthly Rainfall A Case Study for Catarman, Northern Samar, Philippines
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2020, Vol 5, Issue 1
Abstract
This study aimed to derived an equation to estimate the monthly rainfall for Catarman, Northern Samar.The observed monthly rainfall data for Catarman N. Samar, Catbalogan Samar, Legazpi City and Masbate were obtained from the Philippine Atmospheric Geographical Astronomical Services Administration PAGASA . The monthly rainfall records of the three 3 neighboring stations Catbalogan, Legazpi, Masbate were used to identify which of the existing rainfall prediction methods, namely, Normal Ratio Method, Distance Power Method and Multi Linear Regression Method is the basis in the development of a new equation. The accuracy by which the existing methods predict the observed monthly rainfall in Catarman was evaluated using T test for correlated samples and the Pearson’s Correlation Coefficient. Since none of the methods produced estimates nearest to the observed monthly rainfall in Catarman, an equation has been derived Celeste A. De Asis | Benjamin D.
