Dear Colleagues,

Climate change currently affects social resilience and aquatic ecosystems. It alters rainfall patterns, resulting in significant changes in the streamflow. The potential impacts of climate change include shifts in precipitation frequency and intensity, which in turn affect the variability of hydrological dynamics and water quality. Consequently, these changes will have an impact on the planning strategies for social infrastructure development and the management of water resources.

The impacts of climate change on social resilience are multifaceted. Changes in rainfall patterns can disrupt agricultural systems, affecting food security and livelihoods in communities that rely heavily on farming. Droughts and water scarcity can lead to crop failures, livestock losses, and reduced access to clean water for domestic use. These challenges can undermine the economic stability of communities, exacerbate poverty, and increase social inequalities. Furthermore, extreme weather events associated with climate change, such as hurricanes, storms, and flooding, can cause significant damage to infrastructure, including homes, roads, and public facilities. Rebuilding and recovering from such events can be a long and costly process, straining the resources and capacities of communities. The social impacts of climate change-induced disasters can be particularly severe for marginalized populations and vulnerable groups, who often have limited resources and face greater challenges in recovering from such events.

In terms of aquatic ecosystems, climate change poses a serious threat to their health and functioning. Changes in streamflow patterns, driven by altered rainfall regimes, can disrupt the natural hydrological cycles of rivers and streams. This can result in the loss of important habitats, such as wetlands, and negatively impact the reproduction, migration, and feeding patterns of aquatic species. These disruptions can have cascading effects on the entire ecosystem, affecting the abundance and diversity of species that rely on these water bodies. Additionally, changes in water temperature due to climate change can lead to thermal stress and impact the survival of sensitive aquatic organisms. Warmer water temperatures can promote the growth of harmful algal blooms, which can release toxins and harm fish, shellfish, and other aquatic species. Such changes in the aquatic ecosystem can have far-reaching consequences for the fisheries industry, tourism, and the overall ecological balance of the affected region.

Therefore, to better understand the spatiotemporal variation of climate change impacts, the goal of this Special Issue is to explore the nexus between climate change, hydrological dynamics and water quality in a comprehensive and integrated manner. Topics of interest include, but are not limited to, the following:

• Projection and forecasting of flood and drought;
• Streamflow dynamics;
• Impacts on water quality;
• Ecological/ecosystem responses;
• Socioeconomic implications;
• Adaptation and management strategies.

This Special Issue aims to provide a platform for researchers, engineers, and practitioners to share their knowledge and experiences in these fields, and to promote the development of new and innovative methods for climate change evaluation. This Special Issue will contribute to the advancement of knowledge in this critical area and support efforts towards preserving our water resources for future generations.

We look forward to receiving your original research articles and reviews.
