A modelling study was carried out to evaluate the influence of aquifer heterogeneity, as represented by geologic layering, on heat transport and storage in an aquifer used for aquifer thermal energy storage (ATES). An existing ATES system in Agassiz, British Columbia, Canada, was used as a case study. The system consists of four production wells completed in an unconfined heterogeneous aquifer consisting of interbedded sands and gravels. An additional dump well was installed to provide for heat dissipation during the peak cooling periods. Three monitoring wells and the production wells were logged for temperature periodically within the first 1.5 years of operation. A three-dimensional groundwater flow and heat transport model was developed using FEFLOW. Simulation results indicate that heat and (or) cold energy moved preferentially in discrete zones within the aquifer or at least entered the wells over discrete intervals. Monitoring data support model results, but show that thermal storage was successfully achieved despite a significant cooling operation during the first year.

Rockfall is a very common geomorphological process, yet a major hazard mainly in mountainous areas or along man-made slopes, potentially threatening lives, settlements, equipment, facilities and road infrastructure. In Greece, rockfalls are considered to be one of the most common forms of landslide as well as the most common failure mode likely to be triggered by a seismic event. Rockfall hazard assessment is requisite for both safety purposes (countermeasure design), as well as for land planning purposes. In this paper, a new three-dimensional rockfall simulation model, developed in GIS environment, is proposed as a tool for assessing rockfall hazard for a local- or even a regional-scale area. The application provides stochastic analysis, three-dimensional visualization and animation of rockfalls, by taking advantage of the capabilities offered by GIS. By means of case studies we evaluate the simulation model as a tool assisting spatial analysis and planning, which can be used in decision-making and design concerning road infrastructures, or even a large technical work, such as a dam.
