Le Mehauté and Soldate (1978) developed a mathematical model for long term shoreline evolution. The combined effects of variations of sea level, wave refraction, wave diffraction, loss of sand by density currents during storms, by rip currents and by wind, bluff erosion and berm accretion as well as effects of man-made structures such as long groin or navigational structures and beach nourishment were all taken into account. A computer program was developed with various subroutines, which permit modification as the state-of-the-art progresses. The program was applied to a test case at Holland Harbor, Michigan
