Table 1.

Results from the analysis of beaches with rivers and canals within their perimeters or within 600 meters. The categories compared (e.g., a versus b) are given in the first two columns. The columns to the right are patterned off of the first two columns with the statistics for category “a” are provided to the left and the statistics for category “b” are provided to the right
