“…COASTAL ENGINEERING-1978 Due to the development of sophisticated computerized design techniques combined with the availability of new techniques for obtaining estimates of wave directional spectra, it is now desirable for the engineer to predict the power wave spectra at different locations within a proposed harbor during the analysis stages of the design of a harbor. Mobarek and Wiegel (1967) proposed the use of directional spectra, combined with diffraction theory to determine the wave conditions at any desired location in a harbor. This method was applied to a semi-infinite breakwater and compared with experimental results (Mobarek and Wiegel, 1966; see also Fan, 1968;Fan and Borgman, 1970;Wiegel, Al-Kazily, and Raissi, 1971;Harms, 1975).…”

A number of hydraulic laboratory experiments were made of the diffraction of wind-generated waves by a breakwater gap. The directional spectra of the incident wave was used together with the water wave diffraction theory of Penny and Price for a breakwater gap to predict the energy spectra of the diffracted waves. The difference between the predicted values of the energy spectral density and the measured values demonstrated the limits of using the above techniques. It is likely that this is due to the inadequacy of the diffraction theory of Penny and Price for a breakwater gap for certain ranges of B/L.

A mathematical model for long-term, three-dimensional shoreline evolution is developed. The combined effects of variations of sea level; wave refraction and diffraction; loss of sand by density currents during storms, by rip currents, and by wind; bluff erosion and berm accretion; effects of manmade structures such as long groin or navigational structures; and beach nourishment are all taken into account. A computer program is developed with various subroutines which permit modification as the state-of-the-art progresses. The program is applied to a test case at Holland Harbor, Michigan.D D/, FORM AN 73 1473 EDITION OF » MOV 65 IS OBSOLETE UNCLASSIFIED SECURITY CLASSIFICATION OF THIS PAGE
