THE DRAVA RIVER CROSS SECTION MEASUREMENTS Made by : Croatian COMENIUS Team

What is the goal of the task ? finding an equation determination of the cross-sectional area of the Drava River drawing a curve ”How does the depth of the river change with its width ?”

How to solve the task ?

Equipment ferry boat string or a stick ( length : 10 m ) clasps string ( length : 300 m ) measuring tape heavy object

Description of the measurements determine the width of the Drava River firstly, fix one end of the string ( length : 300 m ) on the right shore of the Drava River secondly, get in the ferryboat and transport the second end on the left shore determine the depth of 3 places the first point is situated 20 m from the left shore the second point is situated 140 m from the left shore the third point is situated 250 m from the left shore

Results WIDTH X(m)DEPTH Y(m) 2500, ,16 204,51

Converting of the data

Conclusion measurement results different depth at similar points no precise match with a parabola
