“…This man-made recreational lake was entirely drained by the lowering of the groundwater table by limestone quarrying: as a result cover-collapse sinkholes formed beneath the lake bed and linked the water in the lake to an existing subsurface karst aquifer, which itself was connected to the quarry, causing the lake to drain overnight (Jovanelly, 2014). Similar aquifer drawdown impacts resulting from quarry and mine operations and aquifer over-exploitation have been described in Italy (Parise and Pascali, 2003;Dell'Aringa et al, 2014), China (Jia et al, 2018;Pan et al, 2018), Iran (Heidari et al, 2011;Khanlari et al, 2012) and Belgium (Kaufmann and Quinif, 2002), amongst numerous other examples of this phenomenon in the USA and elsewhere, as reviewed by Langer (2001, p. 15-30). If sinkholes and quarries are legally…”

“…The cover-collapse sinkholes documented during this study are similar to sinkholes developed in other karst areas buried by thick Quaternary overburden deposits that have been impacted as a result of regional water table lowering. As mentioned in the Introduction, there are numerous examples of quarrying or withdrawal of water from aquifers lowering water tables and causing sinkholes to form in surrounding land, due to the removal of buoyant support for sediments or soils above the sediment/limestone contact (Kaufmann and Quinif, 2002;Parise and Pascali, 2003;Heidari et al, 2011;Khanlari et al, 2012;Jovanelly, 2014;Dell'Aringa et al, 2014;Jia et al, 2018;Pan et al, 2018). The process is well-illustrated in the review by Langer (2001, fig.…”

“…The mechanism by which surficial ground collapse is the coupling consequences of groundwater, soil and bedrock, but each one is a little bit different (Beck, 2005;Santo et al, 2017;Santolo et al, 2018). Formation mechanism of collapse sinkhole may be divided into several types, such as subsoil erosion, entrapped air blasting, vacuum cavitation and mechanical vibration et al, which is differentiated by combination characteristic of soil layer, change of groundwater level and karstific development in bedrock (Kang, 1992;Beck, 2005;Jiang et al, 2017;Pan et al, 2018;Xia et al, 2019;Meng et al, 2020). For example, subsoil erosion initially occurred in the channelized path that formed by concentrated groundwater runoff, especially when groundwater level frequently fluctuated between soil-bedrock interface, and then collapsed when upward eroding void grew to a significant size.…”

The cover collapse sinkholes occurred and concentrated in Wugaishan town, Chen zhou city since 1996. The results are combined with results of site investigation, geophysical prospecting and in situ groundwater monitoring data, allowing the development characteristics and formation mechanism of surficial collapse incidents to be summarized. Collapse sinkholes are significantly active in recent years and mostly develop in the rainy season ranging from April to June and generally show a zonal distribution along the topography of study area from SW to NE. 92.31 % of total collapse events occurred in the thickness of overburden material ranged from 0 to 15 m, which indicated that overlying material less than 15 m was easier to collapse. The results show that collapse sinkholes have strong relationship with characteristic of overburden material, which sharply decrease in internal physical and mechanical property of bottom layer. Furthermore, substantial cavities formed within bedrock are the best transport channels and storage spaces for the unconsolidated material, especially under the condition of dynamic undulation of groundwater level. The formation mechanism of collapse sinkhole is divided into three types: infiltration erosion, coupling air implosion with vacuum cavitation and saturation erosion. Each formation mechanism is related to changes of groundwater level. When groundwater level rose above the soil-bedrock interface, saturated subsoil were easier to disintegrate into small particles and migrate downward as the vertical seepage of groundwater. The hydraulic gradient increased and became the predominant factor for the development of soil cavity as groundwater level dropped below the soil-bedrock interface. Moreover, when groundwater level sharply surged up at the relative sealed environment, the upward erosion roof of cavity would be more likely to collapse by the entrapped air blasting.

“…These components include the flow entering or leaving the lake, direct precipitation to the lake surface, and groundwater change (Pan et al 2018). In addition to meteorological factors such as precipitation on the lake drainage area, evaporation from the lake surface, wind speed, humidity, and temperature in the adjacent subatmosphere play an important role in water level fluctuations in the lakes.…”

Determining changes in the water level of lakes is essential in terms of flood control, water resource management, economic development, water-supply planning sustainability, and the sustainability of the ecosystem. Trend analysis is one of the most commonly used tools for detecting changes in the hydrological time series such as lake levels, precipitation and temperature. Trend analyses of meteorological variables and groundwater levels (baseflow components) are crucial toward the assessment of long-term changes in lake levels. This study aims to investigate the trend of long-term change in lakes (Lake Tuz and Lake Beyşehir) and sinkholes (Timraş and Kızören) in the Konya Closed Basin in Turkey. Changes in these lakes and sinkholes were examined along with changes in precipitation and groundwater trends representing the climate in the region. With the assistance of Thiessen polygons, precipitation stations, which affect the lakes and sinkholes, were determined. Several statistical tests exist that help determine the significance of hydrological trends over time. These tests are divided into two categories: parametric and nonparametric. In this study, the non parametric Innovative Sen trend test, the Modified Mann–Kendall trend test, and the parametric Linear Trend test were used. As a result of the trend analysis, it was observed that the water levels of Kızören and Timraş sinkholes decreased over time, and the water levels of Tuz Gölü and Beyşehir lakes increased over time. These results are supported by the trends of precipitation data and groundwater level data of the stations determined by the Thiessen polygons and sub-basin boundaries.
