This project will utilize the most used equipment -&#160; CCD and geophone as main focus for added value operation. The results will be shown through interactive web site. For CCD images, the total variation of grey level will be used further to calculate the arrival time, velocity, and celerity of debris flows. Theory for estimating physical quantities will be derived and warning threshold determination process will be formulated. For geophone data, muti-scale perturbation will be used to construct the signal variation through media. Results will be used to calculated debris flow speed and optimization of geophone installation. All added value results will be focused on Shen –Mu monitoring station. All data and research results will be shown and used for Shen-Mu international research center.土石流監測預警地聲探測器攝影機debris flowMonitoring and warningGeophoneCCD camera
