1. 1. Adapted data collection in field utilizing RMR and the Q-system

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Amanda Olsson; [2024]
   Keywords : Rock mass classification; Q-slope; SMR; Slope stability;

   Abstract : The focus on slope stability has increased rapidly in Norway over the last years due to several unwanted landslides. In Norway, the most used method today to classify the rock mass and to determine the required reinforcement, is the Q-system. In addition to that the RMR method is also a commonly used method.

4. 3. Methodology for Stored Heat “Heat In Place” (HIP) assessment of geothermal aquifers – Exemplified by a study of the Arnager Greensand in SW Scania

   University essay from Lunds universitet/Geologiska institutionen

   Author : Oskar Sundberg; [2023]
   Keywords : geothermal energy; geothermal resource assessment; geothermal potential; volume method; volumetric method; recovery factor; direct use; direct heat; Mesozoic aquifers; Earth and Environmental Sciences;

   Abstract : In the sedimentary bedrock of southwest Scania, located in the southernmost part of Sweden, there are several low-enthalpy Mesozoic sandstone aquifers situated at different depths. These aquifers collectively hold the potential for direct-heat geothermal utilization. READ MORE

5. 4. Water use efficiency in agricultural irrigation in Egypt: A qualitative study on the complexities of utilising fossil groundwater resources in the face of water scarcity

   University essay from Lunds universitet/Ekonomisk-historiska institutionen

   Author : Johannes David Huber; [2023]
   Keywords : Water scarcity; water use efficiency; agricultural irrigation; desert farming; sustainability; groundwater extraction; Nubian Sandstone Aquifer System NSAS ; Business and Economics;

   Abstract : This study examines the adaptive capacity of desert farming in Egypt to imminent water scarcity and discusses the sustainability of fossil groundwater extraction. Through qualitative semi-structured expert interviews, the study identifies clear research and data gaps related to the Nubian Sandstone Aquifer System (NSAS) and highlights the need for a nuanced approach to fossil groundwater extraction that focuses on water use efficiency improvements.
