“…However, in every infrastructure development, negative impacts on the environment that are hard to avoid often emerge. Insufficient planning is frequently the trigger for these negative consequences [3], including aspects of water resource management [4]. Water resources are natural assets that are limited in terms of time and location [5].…”

The Yogyakarta-Bawen toll road tunnel, located in Magelang Regency, Central Java Province, is a national strategic project that connects Central Java and the Special Region of Yogyakarta. It has geology resulting from volcanic processes, resulting in rocks with moderate aquifer properties and low to moderate permeability. The study covers 24 observation points, with 11 locations sampling groundwater for chemical analysis. The analysis results of hydrochemical facies are Na-K-HCO3. Water table depth varies from 623 m to 704 m above sea level, with the water table along the tunnel route at depths of 13-40 m above mean sea level, generally above the tunnel’s elevation. The groundwater flow pattern tends to move from southeast to northwest, perpendicular to the tunnel’s direction. Groundwater quality testing indicates that water in the research area falls under the category of fresh groundwater, based on electrical conductivity and total dissolved solids values. The overall acidity level is generally acidic, except at specific points. In general, the interaction of groundwater with concrete results in weak erosion. It can be concluded that the groundwater at the research location is shallow, situated above the planned tunnel elevation, exhibits hydrochemical facies variations, and has the potential to weakly erode concrete.

The Urdinbide road tunnel goes through the Autzagane aquifer. This important aquifer is located within the hydrogeological area of the Urdaibai Biosphere Reserve, one of the most important biosphere reserves in the Iberian Peninsula, and it is also used as a source of drinking water for some urban areas in the municipality of Amorebieta-Etxano. The construction of the tunnel could pose a potential risk to the normal functioning of the aquifer, so its design included a special procedure for injecting cement and microcement to waterproof the surrounding area of the drilling, preventing the tunnel from functioning as a drain for the aquifer. The project initially included an intensive hydrogeological characterization of the rock massif, as well as a monitoring phase during the construction works, which allowed a real-time verification of the influence of the tunnel construction on the functioning of the aquifer and the restoration of its normal functioning once the works were completed. The work carried out has shown that the construction of the tunnel has not caused a significant impact on the Autzagane aquifer.

“…This formation is widely distributed in the subtropical, tropical, and humid temperature zones (Arıkan et al 2007). Many geological disasters, such as water inrush, rock blasting, and mud gushing, may occur during the excavation of tunnels in the unfavorable geological formation (Golian et al 2021a). As statistically reported by Zhao et al (2013) ; Shi and Yang (2020), more than 100 water and mud inrush accidents have occurred in recent years during tunnel construction.…”

During tunnel construction, water and mud inrush disasters from completely weathered granite usually lead to the serious casualties and economic losses. Predicting these disasters are vital to the safety construction. Considering the critical erosion condition and flow pattern variation at the three stages (Darcy, rapid, and stable flow stages), a seepage erosion model is developed to perform the coupling analysis of water and mud inrush evolution. The model is shown to have favorable accuracy in real-time predicting the erosion region, ground settlement region, and the main hydraulic parameters (i.e., permeability, water inflow, and mud inflow) by comparison with the laboratory tests and field investigations. Then, effects of the model parameters (i.e., particle diameter, erosion coefficient, and ground permeability) on the water and mud inrush are investigated. Results show that (1) with the decreasing particle diameter, the permeability and the water and mud inflow increase gradually. (2) The erosion coefficient mainly affects the evolution rate and time of the water and mud inrush disaster.(3) The water and mud inrush can be controlled when the ground permeability decreased to the 0.2 time of the initial value. The research findings and the proposed model can provide the reference for the water inrush prevention in a similar project.
