Abstract
Flood is one of the most chronic and hazardous natural calamities all over the world. Information about the magnitude of peak streamflow and flood frequency with specified recurrence intervals is necessary to safely and economically design structures that are in, or near streams. The present study is carried out with a view to understand the effects of changing historical peak flows and flood-frequency computations for streams in Netravathi river basin at Bantwal gauging station, Karnataka, India. To accomplish this objective, 39-year records of annual stream flows were tested for historical flood-frequency analyses. The magnitude of annual peak-flow changes over time was computed using the Sen’s slope and Mann–Kendall Test. Peak flows with 50, 20, and 1% exceedance probability (2, 5 and 100-year recurrence interval, respectively) were computed for a stream gauge Bantwal in Netravathi river basin and found out 3933, 5238 and 8804 m3/s, respectively. Sen’s slope from showed the decreasing trend of peak flow with the magnitude of −38.355 corresponding to Mann–Kendall Test.
