River islands are sandbars formed by scouring and silting. Their evolution is affected several factors, among which runoff sediment discharge. The spatial-temporal of seven river in the Nanjing Section Yangtze China was examined using TM (Thematic Mapper) ETM (Enhanced Thematic Mapper)+ images from 1985 to 2015 at five year intervals. following approaches were applied this study: threshold value method, binarization model, image registration, cropping, convolution cluster analysis. Annual...
A river island is a shaped sediment accumulation body with its top above the water’s surface in crooked or branching streams. In this paper, four islands Yangzhong City lower reaches of Yangtze River were studied. The spatio-temporal evolution information was quantitatively extracted using threshold value method, binarization model, and cluster analysis, based on Thematic Mapper (TM) Enhanced Mapper+ (ETM+) images Landsat satellite series from 1985 to 2015. variation mechanism influencing...
Saltwater intrusion is a common issue in the Yangtze River estuary (YRE), significantly affecting nearshore ecological environment and human activities. Using 20 years of runoff data, high-resolution Finite-Volume Coastal Ocean Model (FVCOM) constructed to simulate lower reaches River. This model employed analyze full-depth current salinity characteristics explore influence factors such as runoff, wind, tides, riverbank morphology on saltwater YRE. The model’s accuracy validated by comparing...
