Watershed Model Input Data for the Great Basin Hydrologic Province and a portion of the Northern Mojave Desert

This U.S. Geological Survey data release presents watershed model input point data aggregated for the Great Basin Hydrologic Province and a portion of the Northern Mojave Desert. The original source data was aggregated onto a 200-meter grid, and then converted to a point dataset with each point representing the centroid of a grid cell. The dataset includes information on elevation, impervious surfaces, vegetation cover, vegetation type, and the following soil characteristics: average thickness, percent sand, percent silt, percent clay, available water capacity, and saturated hydraulic conductivity.

本数据集由美国地质调查局（U.S. Geological Survey）发布，包含针对大盆地水文省（Great Basin Hydrologic Province）与北莫哈韦沙漠（Northern Mojave Desert）部分区域聚合生成的流域模型输入点数据。原始源数据先被聚合至200米分辨率的网格，随后转换为点数据集，每个点对应一个网格单元的质心。该数据集涵盖高程、不透水面、植被覆盖度、植被类型，以及以下土壤特性：平均厚度、砂粒百分含量、粉粒百分含量、黏粒百分含量、有效持水量（available water capacity）与饱和导水率（saturated hydraulic conductivity）。
