Water resources quality data following extreme rainfall and floods in the Gaborone catchment, Upper Limpopo basin, Botswana

The dataset contains concentrations of Total Organic Carbon, Chloride, Fluoride, Bromine, Sulfate, Potassium, Aluminium, Calcium, Iron, Magnesium, Sodium, Phosphorus, Chromium, Manganese, Cobalt, Nickel, Copper, Zinc, Arsenic, Selenium, Molybdenum, Cadmium, Lead and stable water isotopes (δD and δ18O) for 25 groundwater and surface water sampling locations, surveyed over the period February 2017 to May 2018 immediately following Dineo floods. The data were collected as part of the PULA project, which aimed at understanding the immediate effect of heavy rainfall and floods on water resources in arid Botswana and their transitional hydrologic readjustment towards the dry period, and the role of these events in supporting either or both resources replenishment and contamination. The project was co-ordinated by the University of Aberdeen, with partners at the Botswana International University of Science and Technology, the Government of Botswana Department of Water Affairs, and the International Water Management Institute. The project was funded by the Natural Environment Research Council as part of its Urgency grants scheme.

本数据集收录了2017年2月至2018年5月期间，紧随Dineo洪水之后，对25个地下水及地表水采样点的总有机碳、氯化物、氟化物、溴、硫酸盐、钾、铝、钙、铁、镁、钠、磷、铬、锰、钴、镍、铜、锌、砷、硒、钼、镉、铅及稳定水同位素（δD和δ18O）的浓度数据。数据收集作为PULA项目的一部分，该项目旨在探讨重度降雨及洪水对干旱地区博茨瓦纳水资源即时影响，及其向干旱期过渡的水文调整，以及这些事件在支持资源补给或污染方面所扮演的角色。项目由阿伯丁大学协调，合作伙伴包括博茨瓦纳国际科技大学、博茨瓦纳政府水务事务部以及国际水资源管理研究所。该项目得到自然环境保护研究委员会紧急拨款计划的支持。
