We studied the significance of stakeholder engagement in climate change adaptation within the context of coastal resilience. Our approach aimed to enhance collaboration in environmental planning processes by leveraging modeling tools to facilitate learning about the complexity of the socioecological system. A comprehensive questionnaire survey was conducted using Google Forms. The questionnaire included clear instructions and structured response formats, aiming to gather stakeholder perspectives on adaptation measures and define action thresholds in response to climate uncertainties. A total of 47 responses were received and included consulting firm professionals, freelance engineers, local authority professionals, port authority professionals, researchers, and university professors in the field of coastal management. The survey data were analyzed using statistical methods in SPSS to identify key insights and patterns. The survey findings offer valuable insights into the effectiveness of adaptation measures, threshold perceptions for initiating adaptation actions, and the dynamics of stakeholder perspectives. Therefore, the importance of incorporating diverse perspectives in climate change adaptation efforts is highlighted. As answers tend to vary for different stakeholder occupations, the urge for collaboration in future decision-making procedures is highlighted. By bridging the gap between stakeholder input and climate change adaptation measures, this study demonstrates the potential of participatory approaches in enhancing resilience and fostering sustainable development in coastal regions vulnerable to climate change.

“…Variations in precipitation and snowmelt water alter river flows, which are subsequently reflected in lake levels and water temperatures. In particular, increased snowmelt water elevates the lake level and affects water temperature (Trikoilidou et al 2017;Mavromati et al 2018;Mentzafou and Dimitriou 2019;Ambrose-Igho et al 2021;Alehu and Bitana 2023;Šarović and Klaić 2023).…”

Climate change-induced extreme weather events, including prolonged droughts and intense rainfall, exert a significant influence on river inflows. These inflows act as vital conduits for nutrient transport, water quality modulation, and the regulation of thermal dynamics in lakes and oceans. In this context, this study conducts a comprehensive examination of the multifaceted effects stemming from river water characteristics, snowmelt water influence, and shifts in precipitation patterns on the stratification dynamics of Lake Biwa in Japan. To facilitate these investigations, a hydrodynamic model was developed to simulate thermal stratification in Lake Biwa. The results demonstrate that an increase in precipitation and river water flow, specifically doubling these factors, leads to noticeable cooling of the lake’s surface layer and a consequent destabilization of stratification during the stratification period. Conversely, halving these factors stabilizes stratification. Furthermore, elevating river water temperature by 5 °C raises water temperature near the upper thermocline, encouraging vertical mixing within the surface layer. Conversely, a 5 °C decrease induces significant temperature fluctuations and an unstable stratification extending from the surface to deeper layers. Notably, the spatial variance in water temperature within Lake Biwa is profoundly influenced by fluctuations in river water temperature. This study underscores the critical importance of considering river plumes in the study of material circulation, stratification dynamics, and ecological well-being in lakes and oceans. Given the mounting concerns related to eutrophication and the prevalence of anoxia in aquatic ecosystems, this research provides invaluable insights into assessing the impacts of river plumes on Lake Biwa’s stratification structure and seasonal dynamics.

The proposed work aims at developing a new set of indices to carry out the energy audit of water systems. The new set consists of both supply and distribution indices and results from a global energy balance applied to a reference network. In this study, the energy audit of two case study networks is presented by the aid of the new proposed indices. Moreover, for each network, different scenarios are considered, differing in the management strategy proposed to increase the energy efficiency of the system. The comparison of the scenarios in terms of indices has allowed for evaluating the most efficient strategy to reduce the pressure exceeding within the network, among different solutions. According to the results, with reference to the case study distribution network, installing both pumps as turbines and pressure reducing valves represent the most efficient strategy, containing the excess pressure and also offering possibility for energy recovery. Moreover, with reference to the water supply system assumed as further case study network, the strategy exhibiting better values in terms of indices is represented by a direct pumping towards the downstream distribution network, instead of pumping towards an upper reservoir and using a valve or a turbine to dissipate the excess pressure. In this work, the proposed indices are demonstrated to be a useful tool for water managers to identify, among different solutions, the most effective intervention to increase the energy efficiency of water systems.
