Abstract

Large and complex karst catchments, like the one in Southern Dalmatia (Croatia) and Western Herzegovina (Bosnia and Herzegovina), are fragile environments requiring careful protection and sustainable water resources management. Understanding the processes that influence karst aquifer water chemistry is essential for the effective protection of water quality and quantity, ensuring sustainable resource availability and minimizing vulnerability to contamination. A hydrogeochemical dataset comprising over 30 groundwater (springs) and surface water samples, was collected in this cross-border catchment area from September 2013 to September 2020, accounting for seasonal variations. Parameters such as Ca2+, Mg2+, Na+, K+, Cl-, NO3 - and SO4 2+ were analysed using atomic absorption, spectrophotometry and ion chromatography at the Croatian Geological Survey's Hydrochemical Laboratory. Alkalinity was measured through volumetric titration and in-situ pH, electrical conductivity (EC), and temperature (T) were measured using a multi-parameter probe. Additionally, stable sulphur isotope 34 (δ34S) analysis was conducted on ten samples collected during two hydrological extremes (April and October 2019) using an IRMS analyser at the Jožef Stefan Institute in Slovenia. These data provides a baseline assessment of the hydrogeochemistry of the area, facilitating research on isotope hydrology, particularly δ34S studies. It could also be used in implementing measures to protect and safeguard groundwater, assess its vulnerability to contamination, and improve existing catchment recharge zones.

克罗地亚达尔马提亚南部和黑塞哥维那西部复杂喀斯特集水区泉水和地表水水文地球化学特征数据集
像南达尔马提亚(克罗地亚)和西黑塞哥维那(波斯尼亚和黑塞哥维那)这样的大型复杂喀斯特集水区是脆弱的环境,需要仔细保护和可持续的水资源管理。了解影响喀斯特含水层水化学的过程对于有效保护水质和水量、确保可持续的资源可用性和最大限度地减少对污染的脆弱性至关重要。2013年9月至2020年9月,在该跨境集水区收集了包含30多个地下水(泉)和地表水样本的水文地球化学数据集,并考虑了季节变化。在克罗地亚地质调查局的水化学实验室,使用原子吸收、分光光度法和离子色谱法分析了Ca2+、Mg2+、Na+、K+、Cl-、NO3 -和SO4 2+等参数。通过体积滴定法测量碱度,使用多参数探针测量原位pH,电导率(EC)和温度(T)。此外,利用斯洛文尼亚Jožef斯特凡研究所的IRMS分析仪,对两次极端水文(2019年4月和10月)期间收集的10个样品进行了稳定硫同位素34 (δ34S)分析。这些数据提供了该地区水文地球化学的基线评估,促进了同位素水文研究,特别是δ34S研究。它还可用于执行保护和保护地下水的措施,评估其易受污染的程度,以及改善现有的集水补给区。

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.
