Groundwater Levels in the Equus Beds Aquifer near Wichita, Kansas, January 2016 (deep point measurements shapefile)

This dataset is the result of measurements of groundwater levels in the Equus Beds aquifer near Wichita, Kansas, in January 2016. Potentiometric surfaces are interpolated for the shallow and deep parts of the aquifer, and rasters of the potentiometric surfaces are included in this data release. Wells were classified as being screened in the shallow or deep parts of the aquifer based on station name (some wells have a layer identifier in the station name) or, if no indication of aquifer layer was given in the station name, based on the depth of the well; wells with depths less than 80 feet below land surface were classified as shallow and wells with depths of 80 feet or deeper were classified as deep. Contours with a 5 foot interval were produced from the rasters and used to map the water levels in the aquifer. The water level measurements can be used to estimate storage-volume change in the study area between predevelopment (circa 1940) and January 2016 the historic low in 1993 and January 2016; and January 2015 and January 2016.

本数据集为2016年1月对美国堪萨斯州威奇托市附近埃克斯贝德含水层（Equus Beds aquifer）地下水位的实测数据成果。针对该含水层的浅层与深层亚区，已通过插值方法生成测压水头面（potentiometric surface），本次数据发布中包含该测压水头面的栅格数据（raster）。监测井依据测井站名被划分为浅层与深层含水层监测井：部分测井的站名中包含含水层分层标识，可直接据此分类；若站名未提及分层信息，则依据井深划分——地面以下埋深小于80英尺的监测井归类为浅层井，埋深大于等于80英尺的则归类为深层井。基于上述栅格数据生成了间隔为5英尺的等值线，用于绘制该含水层的地下水位空间分布图。本次地下水位实测数据可用于估算研究区多个时段的含水层储水量变化，包括开发前（约1940年）至2016年1月、1993年历史最低水位时段至2016年1月，以及2015年1月至2016年1月三个时段。
