single Location statistical Analysis Single Location statistical Analysis involves the statistical analysis of Hecorded Hydrologic Data for Us(~ in making statistical Inference at the location of Data Acquisition. The, primary sources of hydrologic data for use in 'the analysis of hydrologic data are the U.S. Geological Survey and the National oceanic and Atmospheric Administration. The need for single loca- tion statistical analysis of rainfall data does not present itself very often in enginel!ring flood hydrolo- gy however rainfall data can be acquired on floppy disks in a format that can be imported to popular spreadsheet software. This form of rainfall data is available from the National Climatic Center in Ashe- ville, North Carolina. U" S. Geologcical Survey stream- flow data is available from a variet;y of sources. Water Resources Data Books and Water Supply Papers published by the U.S. Geological Survey contain stream gage records and are available from many technical libraries however the most convenient means of accessing stream- flow is from the nationwide data bank called WATSTORE. Thl~ U. S. Geological Survey .Iill make WATSTORE retriev- als for' a very nominal fE"e. The person to contact at thl~ U. S. Geological Survey' for this data would be Bob Ugland (303-236-4882). The statistical analysis of streamflow data at a single location is a useful tool particularly in rural areas where land use characteris- tics have remained reasonably constant for the full period of record. A wide variety of statistical analy- sis techniques have been employed for the analysis of stream flow hydrologic data at a single location. A good reference for various statistical methods for ~ analyzing hydrologic data at a single location is available from Water Resources Publications locally (SE!e Reference No.1).
