Wekiva River GW Recharge Area delineated from 1995 calibrated particle tracking methodology

Note: As of 03/06/2009, this boundary supersedes all other version produced at SJRWMD, until data needs change. This boundary represents the estimated Floridan Aquifer recharge area in the Wekiva Basin, in Lake, Orange and Seminole counties, Florida. This does not represent the full springshed capture zone. The full springshed capture zone has not been delineated using MODFLOW. 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 East-Central Florida (ECF) model, as documented by B. McGurk in SJ2002-3, search https://www.sjrwmd.com.备注：截至2009年3月6日，本边界取代圣约翰斯河水资源管理区（SJRWMD）此前发布的所有版本边界，直至数据需求发生变更。本边界代表佛罗里达州莱克县、奥兰治县与塞米诺尔县境内韦基瓦盆地内估算的佛罗里达含水层补给区范围。本边界并非完整的泉域捕获带，目前尚未通过MODFLOW模型划定完整的泉域捕获带。该区域基于粒子追踪法生成，以美国地质调查局（USGS）的MODPATH模型作为模拟工具，用于追踪水流粒子从终点回溯至源头的路径。本次MODPATH分析基于圣约翰斯河水资源管理区（SJRWMD）发布的佛罗里达中东部区域（East-Central Florida, ECF）模型，相关文档由B. McGurk以编号SJ2002-3发布，可访问https://www.sjrwmd.com查询详情。
