Method for calculating position of first wave scouring pit in front of muddy coast slope dike

The invention mainly relates to a method for calculating the position of a first wave scouring pit in front of a muddy coast slope dike, which comprises the following steps: firstly, acquiring structural parameters and hydrological parameters of the slope dike, outputting the position of a first wave node at the front edge of the slope type seawall through a calculation method for the front edge wave node of the slope dike, and calculating the position of the first wave node according to the position relationship between the first scouring pit in front of the dike and the first wave node; and calculating the position range of the first wave scouring pit at the front edge of the muddy coast slope type seawall. According to the calculation method, the formula structure is simple, calculation is convenient and fast, factors such as different water depths in front of the seawall, wave elements and seawall parameters can be covered, the calculation result has reliability and accuracy, accurate data are provided fo
