Abstract. Groundwater can respond quickly to precipitation and is the main contribution to streamflow in most catchments in humid, temperate climates. To better understand shallow groundwater dynamics in a boreal headwater catchment, we installed a network of groundwater wells in two areas in the Krycklan catchment in Northern Sweden: a small headwater catchment (3.5 ha, 54 wells) and a hillslope (1 ha, 21 wells). The average wells depth was 274 cm (range: 70–581 cm) and recorded the groundwater level variation at a 10–30 min interval between 18. July 2018–1. November 2020. Manual water level measurements (0–26 per well) during the summer seasons in 2018 and 2019 were used to confirm and re-calibrate the water level logger results. The groundwater level data for each well was carefully processed and quality controlled, using six data labels. The absolute and relative positions of the wells were measured with a high-precision GPS and terrestrial laser scanner (TLS) to determine differences in groundwater levels and thus groundwater gradients. During the summer of 2019, all wells with sufficient water were sampled and analyzed for electrical conductivity, pH, absorbance, anion and cation concentrations, as well as δ18O and δ2H. This combined hydrometric and hydrochemical dataset can be useful to test models that simulate groundwater dynamics and to evaluate subsurface hydrological connectivity. We therefore made the data available on https://www.safedeposit.se/projects/82 (Erdbrügger et al., 2022).

浅层地下水位时间序列和来自北方源头集水区的地下水化学调查

摘要。地下水可以对降水做出快速反应,是潮湿、温带气候中大多数集水区径流的主要贡献。为了更好地了解北方源头集水区的浅层地下水动态,我们在瑞典北部 Krycklan 集水区的两个区域安装了一个地下水井网络:一个小型源头集水区(3.5 公顷,54 口井)和一个山坡(1 公顷,21 口井) )。平均井深为 274 厘米(范围:70-581 厘米),并记录了 2018 年 7 月 18 日至 1 日之间 10-30 分钟间隔的地下水位变化。2020 年 11 月。使用 2018 年和 2019 年夏季期间的手动水位测量(每口井 0-26 个)来确认和重新校准水位记录仪结果。每口井的地下水位数据都经过仔细处理和质量控制,使用六个数据标签。使用高精度 GPS 和地面激光扫描仪 (TLS) 测量井的绝对和相对位置,以确定地下水位的差异,从而确定地下水梯度。在 2019 年夏季,对所有水量充足的井进行采样并分析电导率、pH、吸光度、阴离子和阳离子浓度以及 δ18O 和 δ2H。这种组合的水文和水化学数据集可用于测试模拟地下水动力学的模型和评估地下水文连通性。因此,我们在 https://www.safedeposit.se/projects/82 上提供了数据(Erdbrügger 等人,2022 年)。在 2019 年夏季,对所有水量充足的井进行采样并分析电导率、pH、吸光度、阴离子和阳离子浓度以及 δ18O 和 δ2H。这种组合的水文和水化学数据集可用于测试模拟地下水动力学的模型和评估地下水文连通性。因此,我们在 https://www.safedeposit.se/projects/82 上提供了数据(Erdbrügger 等人,2022 年)。在 2019 年夏季,对所有水量充足的井进行采样并分析电导率、pH、吸光度、阴离子和阳离子浓度以及 δ18O 和 δ2H。这种组合的水文和水化学数据集可用于测试模拟地下水动力学的模型和评估地下水文连通性。因此,我们在 https://www.safedeposit.se/projects/82 上提供了数据(Erdbrügger 等人,2022 年)。
