SEAWAT model used to evaluate the potential effects of alterations to the hydrologic system on the distribution of salinity in the Biscayne aquifer in Broward County, Florida: U.S. Geological Survey Data Release

A three-dimensional, variable-density solute-transport model (SEAWAT) was developed to examine causes of saltwater intrusion and predict the effects of future alterations to the hydrologic system on salinity distribution in eastern Broward County, Florida. The model was calibrated to conditions from 1970 to 2012, the period for which data are most complete and reliable, and was used to simulate historical conditions from 1950 to 2012. The model was used to (1) evaluate the sensitivity of the salinity distribution in groundwater to sea-level rise and groundwater pumping , and (2) simulate the potential effects of increases in pumping, variable rates of sea-level rise, movement of a salinity control structure, and use of drainage recharge wells on the future distribution of salinity in the aquifer. This USGS data release contains all of the input and output files for the simulations described in the associated model documentation report (https://dx.doi.org/10.3133/sir20165022). This data release also includes (1) preprocessing python scripts and associated input data files for creating the sensitivity and scenarios runs, (2) flopy source code, and (3) SEAWAT (v4) source code.

本研究开发了一款三维变密度溶质运移模型（SEAWAT），用于探究美国佛罗里达州布劳沃德县东部的海水入侵成因，并预测未来水文系统变化对该区域含水层盐度分布的影响。该模型以数据最为完整可靠的1970至2012年时段的水文条件进行率定，并被用于模拟1950至2012年的历史水文条件。本模型被用于两项研究任务：(1) 评估地下水盐度分布对海平面上升与地下水抽取的敏感性；(2) 模拟抽水强度提升、不同海平面上升速率、盐度控制设施迁移以及排水补给井使用等情景对含水层未来盐度分布的潜在影响。本次美国地质调查局（USGS）发布的数据集包含了相关模型文档报告（https://dx.doi.org/10.3133/sir20165022）中提及的所有模拟输入与输出文件。本数据集还包含：(1) 用于生成敏感性分析与情景模拟的预处理Python脚本及配套输入数据文件；(2) Flopy 源代码；(3) SEAWAT（v4）源代码。
