Traditional flood risk communication fails to bridge the gap between complex technical data and the needs of the public, hindering effective response. This research addresses this gap by developing and validating a novel AI-powered assistant that uses GPT-4 to democratize flood risk information. Our core methodology includes a Retrieval-Augmented Generation (RAG) framework that synthesizes real-time flood warnings, geospatial data, and social vulnerability indices into clear, conversational responses. To validate its effectiveness, we conducted a mixed-methods evaluation, including a comparison across different GPT models. Key quantitative findings reveal that the assistant achieved high performance scores in general flood knowledge (5/5) and handling flash flood alerts (4.3/5). Response times averaged a rapid 12 s for non-function-calling queries, though more complex data retrieval tasks averaged 36 s, highlighting areas for optimization. Our comparison identified GPT-4o as the optimal model for balancing accuracy with response time. The broader implications of this work demonstrate that large language models can serve as powerful tools to translate complex environmental data for non-experts, paving the way for more equitable, engaging, and effective public participation in disaster risk management.

Absence of high-resolution spatial data on Soil and water conservation measures (SWCM) hampers the accuracy of erosion modeling, particularly in regions with complex terrain and frequent land use/cover changes (LUCC). This study integrated multi-source remote sensing (RS), field surveys, and visual interpretation to map SWCM distribution and estimate soil erosion. It further quantified the response of erosion to LUCC. Soil erosion conditions have improved, with an average annual decrease in erosion modulus of 0.51 % and a total reduction of approximately 9.5 × 105 t. LUCC was characterized by cropland reduction, expansion of garden, and increasing landscape fragmentation. Garden development enhances economic returns but may exacerbate erosion when vegetation cover is insufficient. Nonetheless, under similar conservation intensity, slope, and elevation, conversion of cropland or bare land to woodland or garden effectively reduces erosion. The findings provide a new perspective for evaluating soil erosion in fragmented mountainous landscapes with complex management measures.

Flood forecasting is crucial for disaster planning and risk management, yet conventional hydrodynamic-based approaches are often slow in response and computationally intensive. We present a hybrid framework leveraging traditional hydrodynamic modelling with a novel AI model to enable accurate, real-time, and high-resolution flood prediction. To address the computational challenges of large-scale, dense flood prediction, we develop an efficient flood prediction model, FloodTransformer, which possesses three key novelties: variable-size cell embedding, tokenised time-sequence encoding, and physics-informed multi-task optimisation. These components effectively capture complex spatiotemporal dependencies, allowing accurate sequential predictions in a single run. Comprehensive evaluations on both simulated and historical flood events demonstrate FloodTransformer’s excellent accuracy and efficiency: NSE 0.9445, KGE 0.9759 for water-depth prediction, and IoU 0.8180, F1 0.8997 for inundation classification, outperforming all comparative models. With 3s inference enabling multiple horizons in one pass, FloodTransformer offers a robust and practical solution for operational flood risk management.

Deep learning and remote sensing-based chlorophyll-a (Chl-a) monitoring face challenges due to the optical complexity of inland waters and the scarcity of labeled data. To address these limitations, this study develops a self-supervised learning-based deep learning (SSL-DL) framework that leverages both labeled and unlabeled data. Three SSL-DL models are developed: a predictive SSL-DL model, which learns weak labels (incomplete labels); a generative SSL-DL model, which reconstructs input reflectance to capture underlying features; and an integrated SSL-DL model, which combines both. The models are applied to Sentinel-2 imagery of Daecheong and Paldang Lakes in South Korea. Results indicate that SSL-DL models outperform baseline models, with the integrated SSL-DL model achieving the highest test NSE (improvements of 0.1–0.36 over baselines in Daecheong Lake, improvements of 0.03–0.58 in Paldang Lake). The findings highlight the significance of SSL-DL in overcoming data limitations and enhancing scalability, demonstrating the potential for broader environmental remote sensing applications.

Urban water distribution networks are typically represented as 2D models using points and lines, which fail to capture spatial complexity and structural detail. To address these limitations, this study develops an augmented reality (AR) toolbox integrated with a digital twin (DT) framework. The motivation behind this research lies in the need for more intuitive, spatially aware visualization tools to support water infrastructure management and public understanding. AR enables the overlay of virtual content onto real environments, enhancing interpretation of pipe structures and simulation outcomes. A 3D water distribution system was generated from EPANET model data, and a mobile AR application was developed. The system visualizes pollutant dispersion and flow rates through spatially aligned 3D pipe objects. Simulation results are mapped to real-world coordinates, offering enhanced clarity and user engagement. The system is designed to be user-friendly and accessible to nontechnical stakeholders, enabling real-time, location-based interaction with complex water network data.

Developing data-driven models for hydrology and environmental management is challenging for non-experts, such as field engineers and environmental practitioners, due to limited coding experience and the complexity of model training and validation. To address this, we developed MoolML, a free, web-based, no-coding machine learning platform for simplified regression and classification modeling. The name MoolML is derived from the Korean word “물” (mool), meaning “water,” combined with Machine Learning (ML). MoolML integrates key functions such as data preprocessing, model training and prediction, hyperparameter tuning, cross-validation, feature importance analysis, and weather data collection, along with visualization tools for intuitive result presentation. The platform enables users to manage the entire modeling process without coding expertise while supporting data sharing and collaboration. The applicability and efficiency of developing ML models through the platform were tested using hydrological and environmental datasets from South Korea, and it is expected to support comprehensive watershed management.

Citizen science provides extensive litter data, but inconsistent recording limits its use in environmental modelling and decision making. We present a scalable AI-assisted framework that harmonises two major UK datasets, Marine Debris Tracker and Litterati, into a unified, spatially detailed resource. Over 460,000 records (2015–2024) were standardised through a rules-to-embeddings-to-LLM cascade (schema-constrained Llama 3.1) for material classification. Items were clustered by material using K-means at a validated 200 m scale and linked to OpenStreetMap amenities within 500 m to identify accumulation hotspots and contextual features such as parks or transport hubs. Plastic dominated nationally, accounting for 71 percent of entries, while integration with UK Census 2021 data enabled demographic and health analyses where plastic remained highest (68.9 percent). This reproducible framework demonstrates how artificial intelligence can harmonise citizen-science data and enhance spatial modelling to inform targeted pollution prevention and sustainable waste-management strategies.

A generalized, user-friendly data fusion method (Gen-Friberg) to reduce differences between chemical transport models (CTMs) and observational data is implemented to be compatible with widely used CTMs such as CMAQ, GEOS-Chem, and WRF-Chem. Key source code improvements included encapsulating the data fusion algorithm within a single function and enabling parallel processing to minimize runtime for long simulations. We applied the data fusion method to CMAQ outputs and observations from 2010 to 2019 to evaluate the method's performance. After data fusion, pollutant concentration fields showed improved performance. Additionally, we assessed the generalizability of the data fusion method by demonstrating its effectiveness in reducing bias in the GEOS-Chem and WRF-Chem concentration fields using evaluations based on 2017 simulations. Comparisons across CMAQ, GEOS-Chem, and WRF-Chem with and without data fusion demonstrate that data fusion reduces inter-model discrepancies, yielding more consistent concentration fields for use in health and policy assessments.

Over winter freeze–thaw events are notoriously difficult to represent in hydrologic models and have serious implications for the hydrologic function of intermittently freezing regions. Changing climate is leading to more frequent mid-winter thaw events. Midwinter thaw events are often the cause of flooding due to the combined impacts of snowmelt, precipitation, and limited soil infiltrability. A numerically efficient, semi-analytical coupled thermal and mass transport model is presented that represents the ice content of near-surface soil, and reports the depth of freezing/thawing. The model tracks pore ice formation and mean soil temperature in terms of enthalpy. It is tested against data collected in Southern Saskatchewan and is shown to capably reproduce field observations of frozen, thawed or transitioning soils. This numerically efficient model can be incorporated into regional hydrologic models where it is expected to improve predictions of soil ice content, leading to improved estimates of over-winter streamflow and flood potential.

Freshwater modeling is vital for addressing environmental and societal challenges. In two workshops preceding this article, we revealed issues in current modeling practices in New Zealand, with a focus on catchment-level water quality modelling. Predominant were low trust in models, lack of transparency, and models unfit for purpose. This article uses a root-cause analysis to explore these issues, identify causes, and propose solutions. We find that current best practices and research are a good foundation but insufficient to fulfill our freshwater research and management needs. We advocate for long-term national strategies with centralized funding, standardized documentation, data, models, evaluation techniques, and communication methods, along with a centralized open-access platform for collaboration. Our vision is to streamline modeling projects, enhance the accessibility and reliability of models, and foster more effective decision-making processes for the sustainable management of freshwater ecosystems.

We advocate for long-term national strategies with centralized funding, standardized documentation, data, models, evaluation techniques, and communication methods, along with a centralized open-access platform for collaboration. Our vision is to streamline modeling projects, enhance the accessibility and reliability of models, and foster more effective decision-making processes for the sustainable management of freshwater ecosystems.</div></div>","PeriodicalId":310,"journal":{"name":"Environmental Modelling & Software","volume":"197 ","pages":"Article 106820"},"PeriodicalIF":4.6,"publicationDate":"2025-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145689372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
