An Overview of Flood Concepts, Challenges, and Future Directions

Journal of Hydrologic Engineering, Journal Year: 2022, Volume and Issue: 27(6)

Published: March 24, 2022

This review provides a broad overview of the current state flood research, challenges, and future directions. Beginning with discussion flood-generating mechanisms, synthesizes literature on forecasting, multivariate nonstationary frequency analysis, urban flooding, remote sensing floods. Challenges research directions are outlined highlight emerging topics where more work is needed to help mitigate risks. It anticipated that systems will likely have significant risk due compounding effects continued climate change land-use intensification. The timely prediction floods, quantification socioeconomic impacts developing mitigation strategies continue be challenging. There need bridge scales between model capabilities end-user needs by integrating multiscale models, stakeholder input, social citizen science input for monitoring, mapping, dissemination. Although much progress has been made in using applications, recent upcoming Earth Observations provide excellent potential unlock additional benefits applications. community can benefit from downscaled, as well ensemble scenarios consider changes. Efforts also data assimilation approaches, especially ingest local, citizen, media data. Also enhanced compound hazards assess reduce vulnerability impacts. dynamic complex interactions climate, societal change, watershed processes, human factors often confronted deep uncertainty highlights transdisciplinary science, policymakers, stakeholders vulnerability.

Modeling, challenges, and strategies for understanding impacts of climate extremes (droughts and floods) on water quality in Asia: A review

Environmental Research, Journal Year: 2023, Volume and Issue: 225, P. 115617 - 115617

Published: March 4, 2023

The increasing frequency and intensity of extreme climate events are among the most expected recognized consequences change. Prediction water quality parameters becomes more challenging with these extremes since is strongly related to hydro-meteorological conditions particularly sensitive evidence linking influence factors on provides insights into future climatic extremes. Despite recent breakthroughs in modeling evaluations change's impact quality, informed methodologies remain restricted. This review aims summarize causal mechanisms across considering Asian methods associated extremes, such as floods droughts. In this review, we (1) identify current scientific approaches prediction context flood drought assessment, (2) discuss challenges impediments, (3) propose potential solutions improve understanding mitigate their negative impacts. study emphasizes that one crucial step toward enhancing our aquatic ecosystems by comprehending connections between through collective efforts. indices indicators were demonstrated better understand link for a selected watershed basin.

Recent advancement in water quality indicators for eutrophication in global freshwater lakes

Environmental Research Letters, Journal Year: 2023, Volume and Issue: 18(6), P. 063004 - 063004

Published: April 26, 2023

Abstract Eutrophication is a major global concern in lakes, caused by excessive nutrient loadings (nitrogen and phosphorus) from human activities likely exacerbated climate change. Present use of indicators to monitor assess lake eutrophication restricted water quality constituents (e.g. total phosphorus, nitrogen) does not necessarily represent environmental changes the anthropogenic influences within lake’s drainage basin. Nutrients interact multiple ways with climate, basin conditions socio-economic development, point-source, diffuse source pollutants), systems. It therefore essential account for complex feedback mechanisms non-linear interactions that exist between nutrients ecosystems assessments. However, lack set holistic understanding challenges such assessments, addition limited monitoring data available. In this review, we synthesize main freshwater basins only include but also sources, biogeochemical pathways responses emissions. We develop new causal network (i.e. links indicators) using DPSIR (drivers-pressure-state-impact-response) framework highlights interrelationships among provides perspective dynamics basins. further review 30 key drivers pressures seven cross-cutting themes: (i) hydro-climatology, (ii) socio-economy, (iii) land use, (iv) characteristics, (v) crop farming livestock, (vi) hydrology management, (vii) fishing aquaculture. This study indicates need more comprehensive systems, guide expansion networks, support integrated assessments manage eutrophication. Finally, proposed can be used managers decision-makers realistic targets sustainable management achieve clean all, line Sustainable Development Goal 6.

Exploring drought‐to‐flood interactions and dynamics: A global case review

Wiley Interdisciplinary Reviews Water, Journal Year: 2024, Volume and Issue: 11(4)

Published: Feb. 29, 2024

Abstract This study synthesizes the current understanding of hydrological, impact, and adaptation processes underlying drought‐to‐flood events (i.e., consecutive drought flood events), how they interact. Based on an analysis literature a global assessment historic cases, we show can affect risk assess under which circumstances interactions lead to increased or decreased risk. We make distinction between socio‐economic processes. Hydrological include storage runoff processes, both seem mostly play role when is multiyear event occurs during drought. However, process dominant where, this influenced by human intervention needs further research. Processes related impacts have been studied less than hydrological but in general, changes vulnerability important increasing decreasing impacts. Additionally, there evidence water quality problems due events, compared themselves. Adaptation affects (e.g., through groundwater extraction) influencing vulnerability) There are many examples adaptation, limited where certain occur why. Overall, research scarce. To increase our need more comprehensive studies socio‐economic, their interactions, as well that dominance article categorized under: Science Water > Extremes
