Blue Spring Volusia 100 year Capture Zone

This shape file represents the estimated recharge area for Blue Spring in southwest Volusia County, Florida. The area was created based upon a particle tracking methodology, using the USGS model MODPATH as the simulation tool, to trace particles of water from their destination back to their source. The MODPATH analysis is based upon the SJRWMD regional model of the Volusia County model as documented by S. Williams in SJ2006-4 (search https://www.sjrwmd.com for technical publications or https://static.sjrwmd.com/sjrwmd/secure/technicalreports/TP/SJ2006-4.pdf)本形状文件（shapefile）展示了美国佛罗里达州沃卢西亚县西南部蓝泉的估算补给区范围。该补给区基于粒子追踪法生成，以美国地质调查局（United States Geological Survey, USGS）的MODPATH模型作为模拟工具，通过反向追踪水流粒子的最终位置以溯源至其补给源头。本次MODPATH分析基于圣约翰斯河水资源管理区（St. Johns River Water Management District, SJRWMD）的沃卢西亚县区域模型，该模型由S. Williams在SJ2006-4技术报告中详述，相关技术出版物可通过https://www.sjrwmd.com查询，或直接访问https://static.sjrwmd.com/sjrwmd/secure/technicalreports/TP/SJ2006-4.pdf获取报告原文。
