tanks. Five experiments (two in the 6-foot tank and three in the 10-foot 

 tank) were performed in 1972 with different wave energy densities but with 

 the 1971 initial beach slope and initial test length. A sixth experiment 

 was performed in 1972 in the 6-foot tank with a 0.05 initial beach slope 

 and the 1971 wave energy density and initial test length. The test condi- 

 tions are summarized in Table 1. The typical testing season was from May 

 to December. 



This report is part of a series of 8 reports on the 10 experiments, to 

 consist of an experimental procedures report, 6 data reports, and a final 

 analysis report. Each of the six data reports will cover conditions as 

 identified in Table 1. The data in these reports are primarily intended 

 to: (a) Relate temporal and spatial wave height variability to reflection 

 from the movable-bed profile, (b) measure the approach of the profile to 

 an equilibrium condition, and (c) determine as quantitatively as possible 

 the effect of other laboratory constraints (e.g., water temperature, tank 

 length and width, and initial slope) on the resulting laboratory profile. 



This report documents the experimental procedures common to all the 

 experiments, and alleviates the necessity of repeating these procedures 

 in each of the six data reports. The data reports discuss the results 

 from the experiments, and each report includes an appendix documenting 

 the data collection and reduction procedures unique to the experiments. 



Three earlier reports on these experiments are also documented in 

 this report. Chesnutt, et al. (1972) discussed the development of the 

 profiles in experiments 70X-06, 70X-10, 71Y-06, and 71Y-10. Chesnutt and 

 Galvin (1974) analyzed the relationship between reflection variability 

 and profile development in the same four experiments. Chesnutt (1975) 

 analyzed other laboratory effects observed in experiments 70X-06, 71Y-06, 

 and 72D-06. 



II. GENERAL PROCEDURES 



1. Facilities . 



The Shore Processes Test Basin (SPTB) , located in Washington, D.C., 

 was a large, 3-foot-deep, outdoor, concrete basin (Figs. 1 and 2). Within 

 the basin, pairs of 6- and 10-foot-wide wave tanks were constructed of 

 aluminum panels (Figs. 3 and 4). The movable-bed profile occupied the 

 left side (facing seaward) of each pair of tanks, and a 0.10 concrete slope 

 occupied the right side. The concrete side was used for control purposes. 

 The tank walls supported a manually propelled instrument carriage which 

 was used for data collection along the full length of the tanks (see Figs. 

 3 and 4). 



2. Experiment Schedule . 



Each experiment was performed in a series of runs in either of two run 

 sequences. The last column in Table 1 indicates the run sequence for each 

 experiment; Table 2 indicates the cumulative test times at the end of
