Data requirements to use: Monthly streamflow values and a historical time series for the streamflow gauge.;
Data used: N/A;
Data format: N/A;
Data access: N/A;
Concise description:
Uses monthly streamflow values and the methods of normalization associated with SPI for developing a drought index based upon streamflow data. With an output similar to that of SPI, both wet and dry periods can be investigated, as well as the severity of these occurrences.
