Abstract: The study was conducted to determine the effects of water temperature on the results from a movable-bed model study of Masonboro Inlet, North Carolina, with a secondary objective to determine the effects of experimental procedures on the model results. The erratic reproduction of short-period waves near the beach and inlet was found to be the most probable source of experimental error. Other experimental errors discussed include the influence of initial molding of the movable bed, method of simulation of littoral transport approaching the inlet test sections, and bed sounding procedure. The study did not define temperature effects on movable-bed model results; however, no evidence was found to indicate that temperature adversely affected the results of the Masonboro Inlet model tests within the range of temperatures investigated (50 to 78°F). A general course of action to resolve the question of temperature effects is recommended. The study consisted of three pairs of tests. Two pairs of tests were conducted with different water temperatures; the third pair was conducted with the same water temperature and was thus a "control" series. Results of the hydrographic surveys are presented in Appendix A; scour and fill maps are presented in Appendix B; and beach profiles for each test are presented in Appendix C.
