Climate change has caused an increase in the frequency of flood events. Rapid and accurate mapping is essential for disaster monitoring risk assessment. The normalized difference index (NDFI) a detection method with characteristics efficient processing less manual intervention, which can quickly obtain information. However, NDFI would misclassify some permanent water bodies lakes rivers into fl...

Due to the complicated environment there are various types of highway disasters in Shaanxi Province (China). The damages caused are severe, losses are heavy, and have rapidly increased over the years, especially those caused by flood disasters along the rivers in mountainous areas. Therefore, research on risk evaluations, which play important roles in the prevention and mitigation of highway di...

The channel-geometry method is an indirect method of flood estimation which relies on the development of relations between flood discharges, measured at gauging stations, and channel dimensions, measured from natural river reaches in the vicinity of the gauge. Channel-geometry equations enable flood discharges to be estimated at ungauged locations on natural streams from measurements of channel...
