Special Issue Information

Dear Colleagues,

Karst water resources are valuable but also very vulnerable systems at the same time, especially in conditions of increased anthropogenic pressures as well as the impact of climate change. On the other hand, precisely such complex pressures and climatic conditions impose the need for greater use and protection of water resources, which then requires a greater degree of knowledge of the complex conditions and processes in karst water systems. This includes the need not only to describe and quantify hydrological phenomena and processes well, but also to predict possible changes due to such pressures and natural processes in today's dynamic world, and to find solutions for adapting to potentially even more unfavorable conditions. Such research on karst environments implies an interdisciplinary approach, where hydrogeological and hydrological research is the starting point.

This Special Issue is open to the submission of works covering the latest knowledge in this particular domain. Desirable topics of papers include new approaches and knowledge related to the characterization of the investigated karst water phenomena and aquifers, water intakes in karst environments, mechanisms of functioning of karst aquifers and related surface water phenomena, as well as the complex conditions of their protection and management, especially in conditions of upcoming climate changes. We believe that these topics and the papers that will be published will be useful for the further development of not only scientific research methods, but also for solving practical problems in hydrogeology and karst hydrology.

Due to the rapid exploitation of water resources in the Huixian karst wetland in the southwest of China in the past decades, the wetland has suffered from shrinkage in size and serious degradation of ecological functioning. To assess how much water within the wetland could still be taken out for local supply purposes while the wetland can still be kept in its normal ecological functioning. Through the use of multi-methods, including field surveys by a multi-disciplinary team, water balance, Remote Sensing, GIS and numerical simulation, this paper characterizes the wetland regime of the study area and finally determines scenarios of water resource utilization for local water supply within acceptable parameters of wetland ecological health. Through the analysis of the methods, it was found that the hydrological characteristics of the study area were conditioned by not only the karst water but also the regional precipitation fluctuations. A zone of mobile watersheds for Lake Mudong was established as opposed to a conventional single watershed. If the wetland ecosystem is kept at the current status of class III, a scenario of withdrawal of up to 20% of lake inflows could be accommodated. The results and their approaches would provide much-needed information for the protection of the wetland and its sustainable water utilization per se. It would offer a basic reference for similar problems in karst areas of southwest China and other areas alike. Full article
