The analysis of 38 year flood hazard data shows that the flood hazard in Xinjiang Line have self similarity not only in the time alignment (volume fractal dimension Df varied from 0.0497 to 0.0678), but in the space alignment (informative fractal dimension D1 varied from 0.0531 to 0.0797).
In this paper,the improved genetic algorithm based neural network model for modelling the vulnerability of flood hazardaffected body is investigated,the principle and algorithms are described,and its application is illustrated with an example.
Public Perception of Flood Hazard in the Niger Delta, Nigeria
Based on this study, comprehensive flood hazard management strategies for land use planning decision were proposed for the efficient management of future flood disasters.
Only a little portion (8.04%) was found to be the least vulnerable to potential flood hazard.
The estimation of flood hazard areas revealed that a major portion of Greater Dhaka comprised moderate to very high hazard zone.
Using two hazard maps which produced the highest congruence for flood frequency and flood depth, a new flood hazard map was developed by considering the interactive effect of flood-affected frequency and floodwater depth, simultaneously.
