“…Thus, it is necessary to improve MIX to automate input and output data treatment to reduce errors and to accelerate the analysis. More information about the code could be find in Carrera et al (2004); Vázquez-Suñé et al (2010); as well as, its previous application to real case studies (Canovas et al, 2012;Jurado et al, 2016;Scheiber et al, 2018;Tubau et al, 2014). Additional examples are EasyQuim and EasyBal.…”

“…EasyQuim and EasyBal, the previous versions of which were widely used in the hydrogeological international community (especially in Latin American countries), are taught in various international master courses by institutions such as the Universitat Politècnica de Catalunya (www.upc.edu) or by nonprofits such as the Fundación Centro Internacional de Hidrología Subterránea (FCIHS, www.fcihs.org).

Each scientist is specialized in his or her field of research and in the tools that he or she uses during the research in a specified site. Thus, he or she is the most suitable person for improving the tools by overcoming their limitations to realize faster and higher quality analysis. However, most scientists are not software developers. Hence, it is necessary to provide them with an easy approach that enables non-software developers to improve and customize their tools. This paper presents an approach for easily improving and customizing any hydrogeological software. It is the result of experiences with updating several interdisciplinary case studies. The main insights of this approach have been demonstrated using four examples: MIX (FORTRAN-based), BrineMIX (C++-based), EasyQuim and EasyBal (both spreadsheet-based). The improved software has been proven to be a better tool for enhanced analysis by substantially reducing the computation time and the tedious processing of the input and output data files.

“…Precipitation is relatively low and concentrated. The evaporation effect is strong, with an annual average evaporation of 500 mm m 22 . According to precipitation statistics from 2006 through 2016, provided by Liaoning Statistical Information Net [30,31] (figure 3), the average annual precipitation is 738.2 mm.…”

“…In order to provide a scientific basis for water inrush prevention in mining districts, it is of vital importance to determine the cause and source of water inrush. Therefore, the correct and effective identification of the source of mine water inrush is an urgent problem [19–22]. Because of its simplicity, efficiency and low cost, hydrochemical analysis is widely used in the identification of water sources [23–25].…”

During the transition from open-pit to underground mining in iron ore mines, water inrush is a prominent problem for mine safety and production. In this paper, a comprehensive method that incorporates hydrochemical analysis and numerical simulation is proposed to analyse the characteristics of water inrush during the transition from open-pit to underground mining. The proposed method revealed the migration law of groundwater and analysed the source of mine water inrush in the Yanqianshan iron mine located in Liaoning province, China. The results show that the excavated mine roadway is the primary factor affecting groundwater migration and that the source of the mine water inrush is the groundwater in the aquifer around the mine roadway. Moreover, based on the results of the study, appropriate methods for prevention and treatment of mine water inrush were proposed. This approach provides a novel idea for the assessment of water inrush hazards and will serve as a valuable reference for analogous engineering cases.

“…Reinjection started as a kind of wastewater treatment method, but has now transformed into an important tool for achieving sustainable development and utilization of geothermal resources (Stefansson, 1997). However, in many new fields, the common practice is usually to convert abandoned or shallow observation wells to reinjection wells (Fukuda et al., 2005; Kaya et al., 2011; Scheiber et al., 2018). This method leads to the decrease of the effective utilization of wells; on the one hand, because of the limited capacity and the formation plug, the amount of reinjection will decrease as time goes on (Jin et al., 2014).…”

The utilization of aquifer energy is a new technology closely related to the development of injection and production well technologies. Accurately predicting the effective use of geothermal energy storage in a surrounding aquifer is of great significance. A developed theory of groundwater hydro-geothermal transfer is suggested by analyzing the general features of stored energy in aquifers together with the interactions between flow connections and thermal breakthroughs. Based on the water-heat transfer in an aquifer, a coupled numerical model of groundwater flow and heat transfer is established using FEFLOW software for an injection and production wells system in the city of Xianyang to simulate the flow and temperature field. The results show that the key for the formation of a flow connection is the hydraulic gradient. That is, whether the flow connection will occur can be judged quantitatively according to the hydraulic gradient. Flow connections occur more easily through greater flow quantities and quicker injection and pumping rates, which lead to earlier occurrences of thermal breakthroughs. At an operation time of 120 days, to prevent thermal breakthroughs in the production wells, the reasonable well spacing was between 180 and 200 m, and the optimal well spacing was 180 m. This method is of great
