Table 1.--Water and sediment discharges at gage sites,
northeastern Puerto Rico. The periods of record are variable but mostly range from 5 to 20
years. Except as noted, data for stations 1 through 17 are from Gellis and others (1998);
data for stations 18 and 19 are from Gellis (1991). (DA = drainage area; Q = mean
discharge; Qu = unit discharge; Qsy = sediment yield; Qp = peak discharge for period of
record.)
