These programs utilize tools not currently found in existing software and all the OTHA programs have: easy-to-use Visual Basic GUI interfaces, FORTRAN engines, connections to WEB data locations, data conversion utilities, and utilize standard data formats: HEC-DSS databases for daily flows and HEC-FFA input formats for instantaneous peak flows. Various water resources related routines within OTHA include: time-series cross-correlation analysis, trend analysis, volume-frequency/balanced-hydrograph generation, extension of records, synthetic daily flow and peak flow generation, mix-population analysis, total probability theorem analysis, risk/binomial distribution analysis, precipitation-frequency analysis using General Extreme Value 1 distribution, and tests and corrects for stationarity or linear trends of statistical parameters.born digitalproceedings (reports)engCopyright and other restrictions may apply.
