IAH2018 sessions, Daejeon, South Korea


The RGF Commission is organizing two sessions at the upcoming IAH Congress, 9–14 September 2018, Daejeon, South Korea.

The session entitled T2.6 Innovation in regional groundwater flow understanding.
The session attracts abstract related to theoretical or practical aspects of regional groundwater flow. The main focus is put on innovation which can be interpreted in relation to the applied approach or method or simulation technique, theoretical development. Moreover, we are waiting for abstracts demonstrating the practical application possibilities of regional groundwater flow concept in water management, mitigation of climate change or in the exploration of hydrocarbons, geothermal energy and ore deposits.

Furthermore, one whole topic is powered by our Commission, entitled T7 Advances in Karst and Fractured-rock Hydrogeology. Fractured and karstified rock aquifers show different characteristics than porous media, related to the heterogeneity and scale-dependency of hydraulic conductivity. Therefore, the investigation and simulation of flow and contaminant transport in these aquifers represent particular challenges in hydrogeology. Groundwater from these aquifers is a major freshwater resource for human consumption and ecosystems. Furthermore, the specific structure and properties of these hard-rock aquifers also affect the performance and safety of artificial underground facilities. This topic aims to discuss the recent advances in understanding groundwater flow and contaminant transport in karst and fractured-rock aquifers.

Conveners: Nico Goldscheider, Young-Jin Park, Judit Mádl-Szőnyi, Sung-Hoon Ji

T7.1 Recent developments in karst hydrogeology
T7.2 Characterizing fractured rock aquifers
T7.3 Modeling of flow and transport in karst/fractured-rock aquifers
T7.4 The critical zone in karst system (Karst Institute of Geology CAGS, UNESCO-IGCP Special Session)
T7.5 Regional flow systems of deep carbonates – Geological agency, discharge features and practical
consequences (organized by the RGFC)
Understanding the flow conditions and permeability distribution of deep carbonate systems with unconfined
and confined segments are critical because these systems contain significant drinking and thermal water
resources, moreover, hydrocarbon reservoirs and MVT deposits. These areas can be suitable for CO2
sequestration as well. Contrary to this great need, the knowledge of these reservoirs is very limited due to
their depth and consequent high drilling and exploration costs. This session intends to foster and mediate the
scientific discussion about these carbonate systems regarding their flow characteristics, driving forces,
water type, the geological agency of flowing water and the practical application of this knowledge.

The deadline for abstract submission is 31 March.

Dedicated sessions at EGU General Assembly 2018

The RGF Commission is also co-organizing a session at the EGU General Assembly, 8–13 April 2018, Vienna, entitled HS8.2.4 Groundwater flow understanding in water management: Environmental problems and potential interactions with subsurface water ecosystems.

The session aims to bring together scientists studying different aspects related to groundwater circulation and management. Understanding of gravitational groundwater flow requires knowledge of the prevailing flow system from the local to a regional scale. Moreover, problems connected to groundwater management underline the importance of sustainable development of groundwater. The understanding of deep groundwater flow is challenging, as the characterization of large flow systems is difficult due to limited data, especially in the intermediate zone between shallow aquifers and deep anthropogenic activities. Therefore, the combined use of hydraulic, geochemical, geophysical and microbiological characterizations is required to understand the functioning and effects of deep flow on shallow subsurface ecosystems. In this context, the session intends to analyze issues connected to groundwater management and its protection from qualitative and quantitative degradation (e.g. overexploitation, climate change and its consequences on groundwater, and groundwater contamination …) in the context of groundwater flow understanding. Papers related to methods of defining groundwater flow, preventing, controlling and mitigating negative environmental impacts related to groundwater are also welcome. This session is supported by RGFC and seems to be very promising because received 52 abstracts.

Convenor: Jim LaMoreaux, co-convenors: Daniela Ducci, Manuela Lasagna, Xiao-Wei Jiang, René Lefebvre, Luc Aquilina, Judit Mádl-Szőnyi, Christine Rivard, Chrystel Dezayes, Alexis Defresne.

We are looking forward to seeing you in Vienna!

Geological Society of America Annual Meeting 2018

RGFC North American regional co-Chair John Molson, together with René Therrien of Université Laval, are co-chairing a proposed Special Session at the upcoming GSA, entitled Advances in the development and application of hydrogeological models. It will be co-sponsored by the GSA Karst Division.

The submission site will be open in April.
