Flood Risk Assessment in Urban Areas

Dear Colleagues,

More than half the global population now lives in urban areas, a trend that is expected to continue as more people move from rural areas to cities. Estimates suggest that 68% of the global population will live in urban areas by 2050. Urban growth is projected to occur across the board: megacities, major cities, as well as regional and mid-sized cities. These projected increases in urban population will lead to rapid urbanization and, when coupled with climate change, will lead to an increase in flood risk. This is due to multiple factors: changes in the flood hazard, an increase in exposure to flood hazards, and an increase in social vulnerability of populations within cities. Thus, innovative flood risk assessment tools must be developed to address each of these components to assist decision-makers, engineers, and urban planners to manage, mitigate, and reduce flood risk in urban areas.

Thus, for this Special Issue, I invite submissions of original research papers, rapid communications, technical notes, review articles, and discussions on topics related to the latest advances in flood risk assessment in urban areas including, but not limited to:

• Geospatial techniques for flood risk assessment
• Flood risk mapping at various spatial and temporal scales
• Integration of flood hazard, exposure, and vulnerability
• Uncertainty in flood risk estimates and assessment
• Real-time and crowd-sourced data for flood risk assessment
• Early warning systems and decision support systems for flood risk assessment
• Flood risk assessment under changing climate and urbanization scenarios
• Data-driven approaches for flood forecasting, mapping, and assessment

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Geosciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
