Pontbren streamflow data

This dataset contains data collected from a network of 13 stream flow monitoring sites located across the Pontbren study site in mid-Wales, UK. The network was established between 2004-2010 as part of the Pontbren Catchment Study Land Use and Management Multi-Scale Experimental Programme. Data are not available for all sites for the entirety of this duration. 10 of the 13 sites were monitored using bed-mounted acoustic Doppler monitoring systems (Starflows), 2 are monitored using v-notch weir plates with pressure transducers and 1 site simply has a pressure transducer recording stage height. The sub-folders within the main Pontbren streamflow datset folder contain data from the individual monitoring sites. Stage discharge relationships were developed for all sites including those monitored using acoustic Doppler monitoring systems. It is necessary in a lot of cases to use the stage discharge relationship developed in each site to get a better estimate of flow than that provided by the acoustic Doppler monitoring system itself. Data are provided in the form of .txt files and the tipping bucket data is generally split into 6 month blocks. Associated with each data point in the .txt file is a quality assurance code, QA code, in the adjacent column. Details of the dataset, the quality assurance coding system, monitoring locations and stage discharge relationship parameters are provided in the supporting documentation.

本数据集收录了自英国威尔士中部 Pontbren 研究区域内的13个流量监测站点所收集的数据。该监测网络始建于2004至2010年期间，作为 Pontbren 流域研究土地利用与管理多尺度实验计划的一部分。在此期间，并非所有站点的数据均完整可用。其中10个站点通过安装在河床上的声学多普勒监测系统（Starflows）进行监测，2个站点采用V型缺口堰板与压力传感器进行监测，而1个站点仅通过压力传感器记录水位变化。Pontbren 流量数据集主文件夹内的子文件夹包含了各个监测站点的数据。对于所有站点，包括使用声学多普勒监测系统监测的站点，均建立了水位与流量之间的关系。在许多情况下，为了获得比声学多普勒监测系统本身提供的更精确的流量估计，有必要使用每个站点建立的水位与流量关系。数据以.txt文件形式提供，而翻斗式雨量计的数据通常按每6个月分割。每个.txt文件中的数据点均附带一个质量保证代码（QA code），位于相邻列中。数据集的详细信息、质量保证编码系统、监测位置以及水位与流量关系参数的详细信息均包含在配套文档中。
