HS8.2.4: Integrated Water Resources Management in Coastal Aquifers: Seawater Intrusion in a Changing Climate and under Human-Impacted World

Convener: Iolanda Borzì | Co-Conveners: Chiara Cappadonia, Anis Chekirbane, Stefania Lanza, Rudy Rossetto

Coastal aquifers, pivotal freshwater reserves for millions worldwide, are increasingly vulnerable to seawater intrusion due to the joint impacts of climate change and intensive human activity. Rising sea levels, changing precipitation patterns, over-abstraction, land use change, and population growth intensify the stress on these valuable but fragile resources. As salinization threatens groundwater-dependant ecosystem health, agriculture, and urban water supplies, integrated approaches to
monitoring, modeling, and managing coastal aquifers are urgently needed.
This session invites contributions that advance understanding, prediction, and management strategies for minimizing seawater intrusion and ensuring sustainable water resources in coastal regions. We aim to foster interdisciplinary discussion on innovative concepts, methods, and policies that support resilience under global change scenarios.
We encourage submissions related but not limited to:

• Field and modeling studies of seawater intrusion processes in coastal aquifers.
• Impacts of climate change (e.g., sea level rise, extreme weather, shifting recharge patterns) on groundwater salinization.
• Effects of groundwater pumping, land use, and urbanization on aquifer vulnerability.
• Advances in observation techniques: hydrochemical/ isotopic tracers, remote sensing, and geophysical methods.
• Integrated management strategies and decision-support tools for sustainable extraction and adaptation.
• Case studies of coastal aquifer restoration
• Nature-based solutions and Managed aquifer recharge (MAR) to enhance coastal aquifer resilience.
• Socioeconomic, legal, and policy dimensions addressing water quality, stakeholder involvement, and governance.
• Multi-scale approaches: from local to global perspectives.

HS8.2.5: Unraveling the impacts of extreme hydroclimatic events on groundwater security: past and future aquifer responses

Convener: Ilaria Delfini | Co-Conveners: Cristina Corradin, Davide Furlanetto

Extreme hydroclimatic events are expected to increase in both frequency and intensity due to climate change. While their immediate socio-economic and environmental impacts are well recognized, their medium- to long-term implications remain insufficiently understood. Aquifer systems are particularly vulnerable to these effects over extended timescales. Consequences include reduced aquifer recharge and groundwater quality degradation, which can induce cascading processes such as land subsidence, threats to food security, freshwater scarcity, and saltwater intrusion. It is therefore essential to advance our understanding of the full spectrum of qualitative and quantitative impacts, and their computational representation through numerical modeling and machine learning approaches. Such knowledge can foster the implementation of effective mitigation and adaptation strategies to ultimately safeguard groundwater resources and ensure their sustainable use. These measures may range from improved forecasting and modeling of the impacts of extreme events on aquifer systems, to targeted engineered interventions and sustainable management practices.
This session invites contributions that provide insights into innovative methodologies, field case studies, or novel perspectives investigating the qualitative and quantitative impacts that extreme hydroclimatic events exert on groundwater systems. In particular, we welcome studies that address: (i) comparative analysis of methodologies and system responses across different spatial scales and climatic contexts; (ii) novel modeling frameworks including past, present, and projected variations of extreme hydroclimatic events; (iii) characterization and modeling of system memory, including how aquifers and subsurface catchments retain the effects of past events; (iv) analysis of aquifer systems recovery times; (v) evaluation of the consequences of combined climatic and anthropogenic stresses on groundwater systems; (vi) identification and assessment of potential mitigation and adaptation strategies

HS8.2.12 - Approaches for enhancing sustainable water management and solving environmental issues

Convener: Stefania Stevenazzi | Co-conveners: Manuela Lasagna, Jim LaMoreaux, Szilvia Simon, Xiao-Wei Jiang

In a context of societal development and increasing demand for natural resources, human needs and environmental impacts must be considered together in order to sustainably manage these resources, especially with regard to groundwater resources. Therefore, a thorough investigation of groundwater availability that inspires sustainable water consumption and facilitates groundwater management is of high importance. This means considering not only the availability and quality of water resources, but also ensuring the preservation of related ecosystems. Moreover, the impacts on groundwater resources, ecosystems and societies due to ongoing climate change should also be considered.
The objective of this session is to gather case studies and scientific contributions connected to sustainable management of groundwater and its protection from degradation and deterioration, e.g., due to over-exploitation, competition for water resources, natural or anthropogenic contamination, and climate change. Contributions are invited on, but not limited to, the following subjects: (i) the use of environmental tracers (chemical species and isotopes) for investigating natural processes and human impacts on water resources, (ii) the assessment of hydrogeological budgets for the evaluation of water availability, and (iii) methods for preventing, managing and mitigating harmful environmental impacts related to groundwater, as well as (iv) identifying major existing challenges and critical issues. Contributions may span from local, to regional, to continental scale studies.
The Regional Groundwater Flow Commission (RGFC) of the International Association of Hydrogeologists (IAH) is sponsoring the session.
