FLOwPER Database: StreamFLOw PERmanence field observations, Jan 2022 - Dec 2022

IMPORTANT NOTE: This dataset includes spatial locations where streamflow permanence observations (continuous flow, discontinuous flow, and dry) were recorded using the FLOwPER (FLOw PERmanence) field survey available in the Survey 123 mobile data collection application. Additional information to describe the field conditions are included as part of the survey. Field observations in the FLOwPER Database have not been processed for quality control including spatial data accuracy or association with a stream network such as the National Hydrography Dataset. Streamflow permanence observations are collected from several governmental and non-governmental organizations on a continuing basis. This data release is formatted as a shapefile that includes streamflow permanence observations with associated information. Photographs associated with FLOwPER data observations are included. The spatial extent of this dataset is the western United States and includes the following states: Oregon, Washington, Idaho, Nevada, Arizona, Utah, Alabama, and Alaska.

重要说明：本数据集包含采用Survey 123移动数据采集应用内置的FLOwPER（FLOw PERmanence，水流持久性）野外调查工具记录的水流持久性观测点空间位置，观测类别涵盖持续径流、间歇径流与干涸河道。本次调查还包含用于描述野外环境的附加信息。FLOwPER数据库中的野外观测数据尚未经过质量控制处理，包括空间数据精度验证，也未关联至国家水文数据集（National Hydrography Dataset）等官方河网数据集。水流持久性观测数据由多家政府及非政府组织持续采集。本次发布的数据采用Shapefile（形状文件）格式，包含水流持久性观测数据及相关关联信息，同时附带与FLOwPER观测数据绑定的影像资料。本数据集的空间覆盖范围为美国西部，涵盖俄勒冈州、华盛顿州、爱达荷州、内华达州、亚利桑那州、犹他州、阿拉巴马州与阿拉斯加州。
