摘要

该数据集提供了法国Fontaine - Vaucluse喀斯特系统12个不饱和带流量的水文连续数据。这些流动是由断层、裂缝、岩溶管道和多孔岩石的缓慢流动引起的。这种不饱和区流动面板是独一无二的。该数据集包括电导率、温度和放电，通过低噪声地下实验室（LSBB, https://lsbb.cnrs.fr）的人工通道获得，并提供了一个独特的窗口，了解喀斯特含水层不饱和带发生的水文过程。它还提供了廊道内的气压、温度和湿度，以及廊道上方地面的天气参数（雨量、温度、太阳辐射、湿度、风速、风向、气压）。该数据为2022年7月至2024年4月的每小时时间步长，对应于过滤后的数据。流量由自制流量计计算，该流量计由一个有机玻璃管组成，该管收集水，底部有一个压力传感器。通过线性模型将压力转换为体积的水，然后使用与有机玻璃管的填充和排空相对应的极值转换为排放量。通过去除错误值（如由于探头故障或操作员干预造成的极端值），通过实时监测检查连续测量的准确性，以及通过去除非活动流量时的值，对所有数据进行了过滤。该数据集是原创的，因为它监测了各种类型的非饱和带流动，由于缺乏洞穴通道，这些流动很少被监测，特别是石灰岩基质内的缓慢流动。这些数据可以用来评估压力传递，这要归功于降水测量、流动温度和流量；以及由于雨测和电导率的传质。由于最近的气象站在10公里之外，天气数据也可用于改进气候模型。

High-frequency hydrodynamic and hydrochemical data from karst unsaturated zone

This dataset provides hydrological continuous data for 12 unsaturated zone flows of the Fontaine the Vaucluse karst system (France). These flows are caused by faults, fractures, karst conduits, and slow-flows from porous rock. This panel of unsaturated zone flow is unique. The dataset includes electrical conductivity, temperature and discharge, obtained through the artificial galleries of the Low Noise Underground Laboratory (LSBB, https://lsbb.cnrs.fr), and providing a unique window into the hydrological processes occurring in the unsaturated zone of karst aquifers. It also provides air pressure, temperature and humidity inside the galleries and weather parameters at the surface above the galleries (pluviometry, temperature, solar radiation, humidity, wind speed, wind direction, barometric pressure). The data are provided at an hourly time step from July 2022 to April 2024 and correspond to filtered data.

Discharge is calculated from a homemade flowmeter consisting of a Plexiglas tube that collects the water and has a pressure sensor at the bottom. The pressure is converted into a volume of water thanks to a linear model, and then converted into discharge using the extreme values corresponding to the filling and emptying of the Plexiglas tube. All data have been filtered by removing erroneous values such as extremes due to probe malfunction or operator intervention, by checking the accuracy of the continuous measurement with point-in-time monitoring, and by removing values when the flow is inactive.

This dataset is original in that it monitors various types of unsaturated zone flow, which are rarely monitored due to a lack of speleological access, especially slow flows within the limestone matrix. These data can be used to assess pressure transfer thanks to pluviometry, flow temperature and discharge; as well as mass transfer thanks to pluviometry and electrical conductivity. Weather data can also be used to improve climate models as the nearest weather station is 10km away.

期刊介绍： Data in Brief provides a way for researchers to easily share and reuse each other''s datasets by publishing data articles that: -Thoroughly describe your data, facilitating reproducibility. -Make your data, which is often buried in supplementary material, easier to find. -Increase traffic towards associated research articles and data, leading to more citations. -Open up doors for new collaborations. Because you never know what data will be useful to someone else, Data in Brief welcomes submissions that describe data from all research areas.
