ABSTRACT:
A water current force measuring apparatus consisting of a pliable rope or line suspended in the water with its lower end anchored to the bottom while the length of the line is subjected to the forces of the current. The upper end of the line is secured to a tensiometer or strain gauge, which in turn is connected to a float or a series of interconnected buoys or floats. Those floats that submerge, balance the total horizontal current-generated force or drag on the line, which is recorded on the tensiometer. These readings are a measure of the total current forces acting on the line by the surface and subsurface currents to permit the ready determination of the total kinetic energy of the currents. Upon obtaining continuous readings of the strain gauge over a definite period, wave heights and lengths, as well as tidal and other cyclic and non-cyclic water movements of the body of water can be ascertained.
