APPENDIX A 



DATA FROM 104 EXPERIMENTS ON RIPPLE GROWTH AND EQUILIBRIUM FORMS 



Tables A-1, A-2, and A-3 contain data and notes for experiments 

 with the 0.55-, 0.18-, and 0.21-millimeter sands. The experiments 

 are listed chronologically. Special measures carried out between 

 experiments are noted in proper sequence. The value of N shows the 

 stroke for each experiment. Experiments with the bed initially leveled 

 are identified by footnotes and by observations of X^, which pertain 

 only to these experiments. Absence of values for X,n indicates a final 

 bed form too three dimensional for X,r\ to be defined. Included with 

 some experiments are notes on their progress or outcome. These refer 

 mostly to the two- or three-dimensional character of final bed forms 

 with the 0.18- and 0.21-millimeter sands. (With the 0.55-millimeter 

 sand, final bed forms are all two dimensional.) When more than one of 

 the three T, T^, T^, are entered, the first listed is that at which the 

 ripple profile was allowed to develop.
