1. A segmented cylindrical tide staff system for erection at remote areas for dynamic calibration of electronic tide meters and computer models of tides, said tide staff system consisting of a plurality of cylindrical tubes, said cylindrical tube being coupled to a flange at its end through a circular orthogonal hole drilled on a flat surface of the flange, said flange being provided with a plurality of equally spaced slots drilled on the flat surface of the flange, one or more outwardly protruding tide indicating arms being mounted on the flange wherein said tide indicating arm consists of two mutually orthogonal planes, wherein one plane is perpendicular to the axis of the tide staff and the other plane is parallel to the axis of the tide staff, said perpendicular plane being provided with a mounting terminal and a circular hole and said parallel plane being partitioned into two compartments by a separating line, and two or more cylindrical tubes being coupled to each other through slots provided on the flange using coupling means, wherein the flange is coupled orthogonal to the axis of the cylindrical tube, wherein the flange is provided with 3 or more equally spaced slots for coupling two or more cylindrical tubes. 2. A segmented cylindrical tide staff system as claimed in claim 1, wherein threading is provided on an inner of the orthogonal hole. 3. A segmented cylindrical tide staff system as claimed in claim 1, wherein the ends of the circular tube are provided with threading for coupling the tube to the flange. 4. A segmented cylindrical tide staff system as claimed in claim 1, wherein the flange is first tightened to the end of the circular tube and is subsequently welded. 5. A segmented cylindrical tide staff system as claimed in claim 1, wherein the circular tube is subdivided into a plurality of equal segments to facilitate reading of the tide level. 6. A segmented cylindrical tide staff system as claimed in claim 5, wherein adjacent sub segments on the circular tube are painted in two or more differing colors to facilitate reading of tide level. 7. A segmented cylindrical tide staff system as claimed in claim 1, wherein two or more cylindrical tubes being coupled to each other using nuts, bolts and lock nuts. 8. A segmented cylindrical tide staff system as claimed in claim 1, the nuts, bolts and lock nuts are made of stainless steel to prevent rusting during prolonged exposure of the tide staff to saline water medium. 9. A segmented cylindrical tide staff system as claimed in claim 1, wherein the tide indicating arm is mounted in an orthogonal direction to the axis of the tide staff for easily and unambiguously taking the tidal measurements. 10. A segmented cylindrical tide staff system for erection at remote areas for dynamic calibration of electronic tide meters and computer models of tides, said tide staff system consisting of a plurality of cylindrical tubes, said cylindrical tube being coupled to a flange at its end through a circular orthogonal hole drilled on a flat surface of the flange, said flange being provided with a plurality of equally spaced slots drilled on the flat surface of the flange, one or more outwardly protruding tide indicating arms being mounted on the flange wherein said tide indicating arm consists of two mutually orthogonal planes, wherein one plane is perpendicular to the axis of the tide staff and the other plane is parallel to the axis of the tide staff, said perpendicular plane being provided with a mounting terminal and a circular hole and said parallel plane being partitioned into two compartments by a separating line, and two or more cylindrical tubes being coupled to each other through slots provided on the flange using coupling means, wherein two tide indicating arms are mounted on the flange. 11. A segmented cylindrical tide staff system as claimed in claim 1, wherein an edge of the mounting terminal is curved to permit easy orientation of the tide indicating arm in any des ired orthogonal direction with reference to the axis of the tide staff. 12. A segmented cylindrical tide staff system as claimed in claim 1, wherein the tide indicating arm is mounted on the flange through the hole provided on the mounting terminal. 13. A segmented cylindrical tide staff system as claimed in claim 1, wherein the tide indicating arm is mounted on the flange using nuts, bolts and lock nuts already provided for coupling two or more cylindrical tubes. 14. A segmented cylindrical tide staff system as claimed in claim 1, wherein an edge of the parallel plane is rounded thereby avoiding injuring persons during transportation, erection, dismounting of the tide staff and providing optimum fluid dynamic performance. 15. A segmented cylindrical tide staff system as claimed in claim 1, wherein markings in the form of numbers are provided on the surface of the parallel plane for reading the tide level.
