1. Block 14, A definition of the scope and details of the proposed 

 plans of improvement are required before initiation of the fixed-bed test- 

 ing. Initial development of these plans is normally accomplished by the 

 sponsor. The laboratory offers additional suggestions before testing is 

 begun. 



m. Block 15 . The time and cost for fixed-bed testing are highly 

 dependent on the number and extent of possible plans for improvement to 

 be investigated. 



n. Block 16 . Close contact is maintained between the sponsor and 

 laboratory during all aspects of the study, and all output data from the 

 model are supplied by the laboratory to the sponsor; however, a meeting 

 should be held after the scheduled fixed-bed testing is completed to 

 assure that all laboratory and sponsor recommendations and plans have 

 been considered and evaluated. This review will determine if all desired 

 hydraulic data have been obtained and conversion of the model to a movable- 

 bed, if required, could be initiated. 



o. Block 17 . Conversion of the model to a movable-bed model is 

 completed. 



p. Blocks 18 and 19 . Before initiation of the verification of the 

 movable-bed model, analysis of available field data is necessary to assure 

 effective verification. Specifically, information on wave climate, litto- 

 ral transport, prior hydrographic changes to the inlet, stability of the 

 inlet, and any other information applicable to changes that have occurred 

 at the inlet should be defined. 



q. Blocks 20, 21, and 22 . Planning, acquisition, and analysis of 

 prototype hydrographic data are completed. Seasonal surveys and post- 

 storm surveys are necessary. 



r. Blocks 25, 24, and 25 . Simulation of the forces acting on the 

 inlet is also dependent on a long-term knowledge of the wave climate 

 affecting the inlet. Concurrent with the hydrographic survey, a defi- 

 nition of wave conditions is necessary. Data following storms are 

 important. 



s. Block 26. Verification of the movable-bed model consists of a 

 series of "trial-and-error" tests in the model to establish the combina- 

 tion of wave climate and tide conditions required for a reproduction of 

 a known shoal and scour history in the prototype. This is accomplished 

 by initially establishing the long-term distribution of wave energy ap- 

 proaching the inlet and reproducing the distribution in the model. A 

 test is conducted with the wave and spring tide conditions with the move- 

 ment of material documented. A comparison is made between the movement 

 of material in the model and the prototype, and if the trends of the pro- 

 totype are not reproduced, modifications to the wave or tidal conditions 

 are made based on an analysis of the results. Although the magnitude of 

 tidal flow may not duplicate the scaled prototype values, gross distri- 

 bution of prototype flow patterns is maintained. Verification tests are
