Spatial Provinces and Domains of the Central Valley for Textural Analysis

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This digital dataset contains the 9 major areas used to subdivide the Central Valley for the interpolation of the percentage of coarse-grained deposits into the texture model. This texture model was used as input data for the hydraulic properties portion of the Central Valley Hydrologic Model (CVHM). The Central Valley encompasses an approximate 50,000 square-kilometer region of California. The complex hydrologic system of the Central Valley is simulated [...]

本数据集发布于2016年10月1日之前，彼时美国地质调查局（USGS）规范科学数据审核、批准与发布的政策尚未生效，该政策的具体要求详见《美国地质调查局勘测手册第502.8章：基础科学实践：科学数据发布的审核与批准》。本数字数据集包含用于划分中央谷（Central Valley）的9个主要分区，这些分区被用于将粗粒沉积物占比插值至纹理模型中。该纹理模型被用作中央谷水文模型（Central Valley Hydrologic Model, CVHM）水力属性模块的输入数据。中央谷覆盖加利福尼亚州约50000平方公里的区域，其复杂的水文系统正通过[...]进行模拟。
