River-Bed Profiler System

Abstract

The main objective of our system is to minimize weight and amount of material required, thus even reducing requirement
of high specification motor,reduce cost,obtained data wirelessly transferred to the control room,generate graphical form
of river surface, the current and old data can be accessed for further analysis.
Its a high measurement of river bed surface topography in model type rivers are useful in studies to analyse energy,
momentum, bed surface elevation, for rivers, lakes, and reservoirs. This project concept is finding the depth of the river
across a section of its stream by using ultrasonic sensor and then obtained data is saving the data in a data storing
device , which then can be brought into an excel format file. The data then can be obtained is converted in a graphical
format giving us a topographical map of the river bed. For this, a movable mechanical setup on rails will be equipped
with sensors for depth measurement and motors for moving the setup across the river. An ultrasonic sensor gives us the
depth from the position of sensor to the river bed. The values obtained from ultrasonic sensor can be used to calculate
the actual depth of the river. Finally, the data collected thus will be used to generate a graphical representation of the
collected data i.ea river-bed profile.
To satisfy the objectives we replace PLC by arduino controller so the we reduce processing time,use metal steel material
to design hardware, for smooth motion feet the rod in bearings,use ultrasonic sensor to obtained surface profile, DC
motor used to drive sensor assembly from star to end so the complete surface of river had been scaned.to plot 3D graph
use MATLAB and finally obtained 3D image of river surface to control system through remote location we create
graphical user interface(GUI)using MATLAB.
At the end of project, we have developed system able to detect depth of the river and obtained data will be sent to the
control room at the remote location wirelessly.Using obtained data the system plot 3D image of river surface
