The construction of one of the high-speed railway tunnels between Malaga and Córdoba (South Spain) beneath the Abdalajís mountains occasioned a series of hydrogeological problems with geotechnical and environmental impacts. The double tunnel, 7,300 m in length, runs south to north across several lines of small, calcareous mountains that have a highly complex structure. Beneath the Jurassic limestones lie Triassic clays and evaporites. Overlying the limestones is an essentially marly and… 
Water inflow into tunnels: assessment of the Gerede water transmission tunnel (Turkey) with complex hydrogeology
The Gerede is the longest and most problematic water transmission tunnel in Turkey, at 31.6 km long with an overburden of 600 m. The tunnel will transmit water from the Ulusu river to the Camlidere
Study on Groundwater System Effect of Tunnel Drainage Control in Karst Valley
A traffic tunnel which is under construction passes through an anticline karst valley area in Chongqing China, in difficult geological conditions. Many buildings lie above the tunnel, the buried
A review of the effects of tunnel excavation on the hydrology, ecology, and environment in karst areas: Current status, challenges, and perspectives
Abstract Due to a lack of awareness of environmental protection at the beginning of tunnel excavation and the unique ecological vulnerability of karst areas, tunnel excavation is beginning to have
Evaluation of hydrogeological impact of tunnel engineering in a karst aquifer by coupled discrete-continuum numerical simulations
Abstract Anthropogenic disturbance of karst groundwater systems by large-scale underground engineering activities is an important topic but is difficult to address due to the compound influence of
Investigation of the impacts of tunnel excavation on karst groundwater and dependent geo-environment using hydrological observation and numerical simulation: a case from karst anticline mountains of southeastern Sichuan Basin, China
The results suggested that negative impacts such as loss of surface and underground water, ground collapse, and house deformation would be posed directly and indirectly to the karst groundwater system and its dependent geo-environment as the result of groundwater level drawdown by tunnel excavation.

Underground engineering activities such as tunnelling are commonly involved in large-scale hydraulic and hydropower projects. In karst regions, tunnel engineering often encounters geological
Interaction between groundwater and TBM (Tunnel Boring Machine) excavated tunnels
A number of problems, e.g. sudden inflows are encountered during tunneling under the piezometric level, especially when the excavation crosses high transmissivity areas. These inflows may drag
The anthropogenic impact on Mediterranean karst aquifers: cases of some Spanish aquifers
Mediterranean karstic aquifers are a major source of water supply for drinking water and agricultural use. In semiarid areas, the risk of causing an intensive exploitation is high, leading to
Response of plants water uptake patterns to tunnels excavation based on stable isotopes in a karst trough valley
Abstract Karstic aquifers are very sensitive and fragile to environmental changes. With more tunnels excavated in karst areas, groundwater levels are increasingly lowered and resulted in changed
Excessive groundwater inflow during TBM tunneling in limestone formation
Abstract A sudden increase of groundwater inflow of 670 tons a day was experienced during tunneling in a limestone formation at around 53 m below the ground surface. The limestone cavities were


Natural and anthropogenic hazards in karst areas: an introduction
The distinctive hydrology and landforms of karst create a very special environment. Although several types of karst have been identified worldwide, a common thread is the dominantly subterranean
Hazard connected to railway tunnel construction in karstic area: applied geomorphological and hydrogeological surveys
Abstract. In a mature karstic system, the realisation of galleries using the methodology of railway tunnel boring machine (TBM) involves particular problems due to the high risk of interference with
Ground settlements above tunnels in fractured crystalline rock: numerical analysis of coupled hydromechanical mechanisms
Vertical settlements with magnitudes reaching 12 cm were measured in fractured crystalline rock several hundred metres above the Gotthard highway tunnel in central Switzerland. Such magnitudes of
Karst groundwater: a challenge for new resources
AbstractKarst aquifers have complex and original characteristics which make them very different from other aquifers: high heterogeneity created and organised by groundwater flow; large voids, high
Groundwater residence times and flow paths in fractured rock determined using environmental tracers in the Mission Tunnel; Santa Barbara County, California, USA
Abstract. Multiple geochemical tracers [ion chemistry, stable isotopes of water, chlorofluorocarbons (CFC), tritium] and a 25-year-long record of discharge were used to understand residence times and
Karstification and groundwater flow
One of the principal aims of hydrogeology is to propose a reasonably adequate reconstruction of the groundwater flow field, in space and in time, for a given aquifer. For example, interpretation of
Groundwater flow and contaminant transport in carbonate aquifers
Carbonate aquifers are an important source of water throughout the world. They are complicated systems and not always easy to interpret. Caves and channels form in the rock, leading to complex flow

Study of hydrographs of karstic aquifers by means of correlation and cross-spectral analysis
Correlation and cross-spectral analysis can be applied to the study of karstic aquifers to characterize the transformations in these systems between the input function (precipitation) and the output
