“…Recently, Linares et al (2017) found a good correlation between temporal sinkhole clusters in the Fluvia Valley and drought periods as revealed by precipitation, river discharge and piezometric data. In the SMCV, Fort (1998), Abellán and Campos (2008), and Abellán (2010), based on historical data previous to the oldest precipitation records, also report a temporal association between droughts and sinkhole events.…”

“…3A): (1) the Garrotxa structural complex; and (2) the Ripoll Synclinorium. The southern side of the Garrotxa structural complex is dominated by steeply dipping Mesozoic-to Eocene-age carbonate formations that form the Garrotxa carbonate massif, considered as the main recharge area for the karst aquifers in the region (e.g., Vidal-Pardal, 1957;Sanz, 1981Sanz, , 1985Linares et al, 2017) (Fig. 2 and 3A).…”

“…Here, we describe the main features of this artesian karst aquifer following the investigations carried out a few decades ago Bach et al, 1986), and incorporate some modifications to previous concepts. These novel ideas are based on the extensive knowledge gained recently on the stratigraphy and structure of the area (Martínez et al, 1997(Martínez et al, , 2000Carrillo et al, 2014;Linares et al, 2017) and new hydrogeological and hydrochemical data.…”

The Garrotxa-Banyoles artesian aquifer system in NE Spain includes zones with epigene and hypogene evaporite karst and sinkhole development. The sinkhole fields related to hypogene evaporite dissolution are associated with the discharge zones of the aquifer, where groundwater from a confined limestone rises traversing an overlying gypsum formation capped by thick marls. This work analyses the sinkhole field developed in the Sant Miquel de Campmajor Valley (SMCV), a discharge area of the aquifer, where a cartographic inventory including 94 sinkholes has been produced. Sinkholes in this hypogene gypsum karst are mainly large caprock-collapse sinkholes rooted in deep-seated cavities generated by interstratal hypogene karstification, as corroborated by an electrical resistivity imaging (ERI) survey. They show a nonclustered distribution within the sinkhole field and the variations in size and density across the area are mainly controlled by the thickness of the marl caprock. The magnitude and frequency relationships of the sinkholes can be modelled with a high goodness of fit with a log-normal function, like in other regions of the world. However, in this deep-seated hypogene system the depressions show much larger dimensions. ACCEPTED MANUSCRIPT A C C E P T E D M A N U S C R I P TPotential differences between the sinkholes developed in hypogene and epigene karst environments are discussed, including their distribution with respect to the groundwater flow system, their spatial patterns and dimensions.

“…Hence sinkhole database shall contain the following aspects viz., exact location, magnitude and frequency relationships of sinkholes, Genetic type, Chronology, Activity, including subsidence rates, kinematical behavior (gradual, episodic or mixed) relationship with conditioning and triggering factors [8], [9], [10], [11], [12], [13], [14]. Sinkhole inventory with chronological data showed a good correlation with drought periods [15]. In this point of view, a systematic approach has been made to generate the present inventory data.…”

Inventory data on the sinkhole occurrences from Proterozoic Cuddapah Basin, India

et al. 2019

This data article provides the inventory data on sinkhole occurrences for the first time from Proterozoic Cuddapah Basin, India. Unexpected ground subsidence incidents are taking place with ground breaking sounds and forming in the Cuddapah Basin since 2007 and their frequency increasing from 2015 to 2017 (15 sinkholes over night in and around Buggavanka River). Such incidents are creating panic situations in the general public of this area which was not experienced in this region ever before. It is interesting to note that majority of sinkholes are forming subsequent to heavy rains and sudden recharge, especially in and around Buggavanka and Chitravati River beds. Hence, there is a strong need for the data on the sinkhole occurrences for detailed field investigations in future. Since, sinkhole inventory is a vital and pioneering step in sinkhole hazard analysis, the consistency of sinkhole hazard and vulnerability maps and the efficiency of the mitigation measures chiefly rely on the accuracy, completeness, and fidelity of the sinkhole inventories. Geospatial technologies played a major role in this inventory in terms of data collection, editing and analysis of various thematic maps.

“…Climate change has been recognized as one of the major factors that have great impacts on drought (e.g., Hanson and Weltzin, 2000;Aherne et al, 2006;Hirabayashi et al, 2008;Ahn et al, 2016;Gizaw and Gan, 2017;Linares et al, 2017;Tietjen et al, 2017). Even a small change in climate may cause a dramatic change in hydrological cycle, leading to more frequent hydrological extremes (e.g., Pilling and Jones, 2002;Chen et al, 2011;Vicuna et al, 2013;Gu et al, 2015;Shi and Wang, 2015;Hoang et al, 2016;Shi et al, 2016aShi et al, , 2017a.…”

Drought is a complex natural hazard that may have destructive damages on societal properties and even lives. Generally, socioeconomic drought occurs when water resources systems cannot meet water demand, mainly due to a weather-related shortfall in water supply. This study aims to propose a new method, a heuristic method, and a new index, the socioeconomic drought index (SEDI), for identifying and evaluating socioeconomic drought events on different severity levels (i.e., slight, moderate, severe, and extreme) in the context of climate change. First, the minimum in-stream water requirement (MWR) is determined through synthetically evaluating the requirements of water quality, ecology, navigation, and water supply. Second, according to the monthly water deficit calculated as the monthly streamflow data minus the MWR, the drought month can be identified. Third, according to the cumulative water deficit calculated from the monthly water deficit, drought duration (i.e., the number of continuous drought months) and water shortage (i.e., the largest cumulative water deficit during the drought period) can be detected. Fourth, the SEDI value of each socioeconomic drought event can be calculated through integrating the impacts of water shortage and drought duration. To evaluate the applicability of the new method and new index, this study examines the drought events in the East River basin in South China, and the impact of a multi-year reservoir (i.e., the Xinfengjiang Reservoir) in this basin on drought analysis is also investigated. The historical and future streamflow of this basin is simulated using a hydrologic model, Variable Infiltration Capacity (VIC) model. For historical and future drought analysis, the proposed new method and index are feasible to identify socioeconomic drought events. The results show that a number of socioeconomic drought events (including some extreme ones) may occur in future, and the appropriate reservoir operation can significantly ease such situation.
