Statistical Modeling of Spring Discharge at Ponce de Leon, Green, and Gemini Springs in Volusia County, Florida. Special Publication SJ2007-SP9

摘要

The objective of this study is the development of daily spring discharge time series for PDL, Gemini, and Green springs from an assortment of auxiliary data such as: (a) previously recorded springs discharge rates at the springs of interest and at adjacent springs, (b) groundwater level measurements from adjacent monitoring wells, and (c) rainfall data from nearby gauging stations. The study will investigate the correlation structure between various data types, and test the applicability of simple multivariate linear models to generate daily discharge records based on these other variables for the common period of record. This report presents the results of exploratory data analysis (EDA) for rainfall, water level and spring discharge data for PDL, Gemini, and Green springs. It also explores the use of empirical models to provide estimates of daily discharge at these springs. These statistical models will take advantage of all available data to try to provide the most accurate estimates. In general, early time records are sparse and often not available for a number of locations.
