Abstract

The daily data are summarized to monthly as follows:
Daily average CFS are summed for each month and multiplied by 86400 (seconds per day) to yield cubic feet per month. This value is divided by the particular watershed area and multiplied by another conversion factor to yield cm water equivalent depth discharged by each watershed per month. This allows direct hydrologic comparison of watersheds of different sizes. Time series plots illustrate the biennial periodicity of high and low discharges, and particular floods and droughts. October 1970 was the historic flood for PR, recently exceeded during the passage of Hurricane Hortense in September 1996. The historic drought occurred during 1993-1994 and is clearly visible in these records.

Table 1. United States Geological Survey (USGS) streamflow records from the Luquillo Experimental Forest. The periods of record presented here end with the 1994 water year (except for those stations whose records ended earlier). Watershed records are subdivided (a,b, etc.) when substantial gaps exist. The watersheds indicated with abbreviations are those where streamwater chemistry has also been measured.
