Problem statement: Making iron ore is one of the largest mining projects in south east of china. Due to the development of mining activities in that site, it has become necessary to increase the depth of exploration. Increase the exploration depth makes the mining tunnels subjected to the karst water inrush. Approach: A hydrological and a hydrogeological model for the Makeng area have been developed, which yield information on relevant parameters such as groundwater recharge and margins' lateral inflow, to estimate aquifer yield. USGS flow code, MODFLOW 2000, was used to produce the numerical model. Collected GIS based information was synthesized in a finite difference numerical model. The regional steady and transient-state flow was calibrated under pre-development conditions assuming an equivalent porous medium approach. Results: Water budget calculations show that the total groundwater flow in regional aquifers amounts to 2.98 mm 3 year −1 . Infiltration from precipitation provides 61.7% of the groundwater supply, while 21% comes from lateral inflow and the remaining 17.3% is induced recharge from surface waters. Discharge from regional aquifers occurs through springs outflow 88.5% and flow to streams 11.5%. Conclusion/Recommendations: Although the karstic nature of the limestone aquifer the equivalent porous-medium flow model is appropriate to represent hydraulic heads and recharge/discharge relationships on a regional scale. The results of this study can be used to predict the required amounts of pumping and the possible locations to dewater the groundwater around the mining tunnels.

Domain-specific languages (DSLs) are languages tailored for particular domains. Many frameworks and tools have been proposed to develop editors for DSLs, especially for desktop IDEs, like Eclipse. We are witnessing the advent of low-code development platforms, which are cloud-based environments supporting rapid application development by using graphical languages and forms. While this approach is very promising, the creation of new low-code platforms may require the migration of existing desktop-based editors to the web. However, this is a technically challenging task. To fill this gap, we present ROCCO, a tool that migrates Eclipsebased graphical modelling editors to the web, to facilitate their integration with low-code platforms. The tool reads a meta-model annotated with EuGENia annotations, and generates a web editor using the DPG web framework used by the UGROUND company. In this paper, we present the approach, including tool support and an evaluation based on migrating nine editors created by third parties, which shows the usefulness of the tool.
