Digital data sets that describe aquifer characteristics of the alluvial and terrace deposits along the North Canadian River from Oklahoma City to Eufaula Lake in east-central Oklahoma

This data set consists of digital polygons of a constant hydraulic conductivity value for the alluvial and terrace deposits along the North Canadian River from Oklahoma City to Eufaula Lake in east-central Oklahoma. Ground water in 710 square miles of Quaternary-age alluvial and terrace deposits along the North Canadian River is an important source of water for irrigation, industrial, municipal, stock, and domestic supplies. The aquifer, composed of alluvial and terrace deposits, consists of sand, silt, clay, and gravel. The aquifer is underlain and in hydraulic connection with the upper zone of the Permian-age Garber-Wellington aquifer and the Pennsylvanian-age Ada-Vamoosa aquifer. Some of the polygon boundaries were digitized from [...]

本数据集包含美国俄克拉荷马州中东部区域，沿北加拿大河从俄克拉荷马城至尤福拉湖的冲积与阶地沉积层所对应的恒定导水率（hydraulic conductivity）数值的数字多边形要素。沿北加拿大河分布的710平方英里第四纪冲积与阶地沉积层中的地下水，是灌溉、工业、市政、牲畜及生活供水的重要水源。该含水层（aquifer）由冲积与阶地沉积层构成，其组分包括砂、粉土、黏土及砾石。该含水层伏于二叠纪盖奇-威灵顿（Garber-Wellington）含水层上部带与宾夕法尼亚纪阿达-瓦穆萨（Ada-Vamoosa）含水层之下，并与二者保持水力联系。部分多边形要素边界系从[...]数字化而来。
