MICROPROCESSOR BASED SCOUR MEASUREMENT

Abstract

The detachment of bed material and lowering of bed, known as scour, is being studied in hydraulics section of Civil Engineering Department. To study the rate of scour, profile indicator is being used. The data from the profile bed indicator is being recorded on graph through graphical plotter. This graphical plotter is very slow. For further calculations, this graphical value is converted into decimal value which is strenuous. Moreover many readings are nece-ssary in •the first few seconds to record scour accurately. To avoid the sluggishness and the strain to read data from graph, an attempt is made in this dissertation to read data from profile indicator and T)rint the decimal value uito third decimal much faster. A single channel :ADC interface and a parallel printer interface have been developed for the purpose. In the continuous mode of recording data., about 7 readings/second rate has been achieved. Chapter-1 deals with the simulated model and the instru-ment to convert the scour value into analog eruivalent, profile indicator.
