| 内容記述 | In coastal fisheries of Japan, facilities such as set-nets, net cages, and artificial reefs are commonly used. Designing of such facilities requires calculation of the wave force. However, wave force calculations have previously been made using a computer because the mathematical treatment of waves is complex and even in the easiest wave theory, a hyperbolic function was applied. Furthermore it needed an integral calculation incorporating the water depth. On the other hand, currently available scientific electronic calculators are commonly equipped with a hyperbolic function and memory function. Consequently, we devised a simplified method of wave force calculation using a scientific electronic calculator and compared it with the conventional method using a computer. We regarded such fishery facilities as submerged cylinders for the sake of simplicity and caleulated the wave force acting on them by both methods. It became clear that we can regard that there is little difference between wave force estimated by the simplified method and the one by the conventional method if the cylinder length is smaller than 0.167 times the wave length. That means the simplified method is effective. Finally, the calculation by the simplified method requires only a scientific electronic calculator, which allows the wave calculation to be easily done by hand. Furthermore the simplified method is applicable for use in lectures about wave force and thus has applications in education. | |||||
