Special Issue Information

Dear Colleagues,

Water-related hazards and climate change, including flood and drought, are considered among the most complex natural phenomena which are related to high numbers of fatalities, causing severe effects on natural, eco-, and socioeconomic systems. Determination and prediction of the trends of these extreme events are fundamental and challenging topics in hydro-climate studies. Therefore, this Special Issue will be focused on all aspects of extreme hydro-climate conditions including, but not limited to, hydrometeorology, atmosphere, and hydrology (from local to watershed) under various scales. Studies on all manner of the modeling, forecasting, assessment, and analysis of hydro-climate extremes are welcome, including estimation of extreme events by means of modeling, monitoring, and sensors; forecasting and warning technologies for extreme hydro-climate conditions;  early identification of a range of natural disasters such as drought, floods, flash-floods, landslides, avalanches, serious cases of hail damage, and external and internal mechanisms; assessment and projection of historical and future regimes (climate change scenarios, CIMIP5, CIMIP6); interaction between atmospheric and hydrologic systems; impacts and changes on natural systems, social systems, and economies. Studies may also consider evacuation, vulnerability and recovery, and mitigation and adaptation strategies for extreme hydro-climate conditions.

The Earth Observation (EO) domain can provide valuable information products that can significantly reduce the cost of mapping flood extent and improve the accuracy of mapping and monitoring systems. In this study, Landsat 5, 7, and 8 were utilized to map flood inundation areas. Google Earth Engine (GEE) was used to implement Flood Mapping Algorithm (FMA) and process the Landsat data. FMA relies on developing a “data cube”, which is spatially overlapped pixels of Landsat 5, 7, and 8 imagery captured over a period of time. This data cube is used to identify temporary and permanent water bodies using the Modified Normalized Difference Water Index (MNDWI) and site-specific elevation and land use data. The results were assessed by calculating a confusion matrix for nine flood events spread over the globe. The FMA had a high true positive accuracy ranging from 71–90% and overall accuracy in the range of 74–89%. In short, observations from FMA in GEE can be used as a rapid and robust hindsight tool for mapping flood inundation areas, training AI models, and enhancing existing efforts towards flood mitigation, monitoring, and management.
