CBSE Science Fair Exhibition Project, “ Pulse Pipe ” Theme “Disaster Management” for Class 9, Class 10 and 12

Project Name : Pulse Pipe (an early warning system for a land slide)

Theme Name : Disaster Management

Landslides are one of the most common natural disasters occurring on the hill slopes and taking lives of the people and destroying their properties in the surrounding area. It is practically impossible to stop a landslide but, if a system could predict a landslide before it occurs it would give us enough time to minimize or avoid the risk and also ensure fast recovery from the adverse impacts of the disaster. Keeping this fact in mind we have come up with the idea of „Pulse Pipe‟ an early warning system for landslides.

In this idea we have installed coaxial cables into an unstable slope. These cables have some characteristic impedance values in them. This impedance changes whenever the wire will be deformed. Whenever, there will be any disturbance on the slope the wire will get deformed and we will get a reflected signal which will be interpreted as a peak on the graph that would be a voltage depth graph. The amplitude of the peak will depend on the amount of displacement that has taken place. Using the amplitude value and the time interval to reach the velocity of the disturbance will be calculated and an inverse of velocity and time graph will be plotted. From this graph we can calculate the time internal before the impending landslide. Once we get the idea of how much time is left before the landslide we can inform various agencies in the surrounding area to start taking immediate measures to save the people.
