Probabilistic envelope curves for design flood estimation at ungauged sites

Design Flood Estimation in Ungauged Catchments: Quantile Regression Technique And Probabilistic Rational Method Compared

Estimation of design floods in ungauged catchments is frequently required in hydrological practice and is of great economic significance. The most commonly adopted methods for this task include the Probabilistic Rational Method, the U.S. Soil Conservation Service Method, the Index Flood Method and the U. S. Geological Survey Quantile Regression Technique. The Probabilistic Rational Method has b...

Flood Frequency Quantification for Ungauged Sites using Continuous Simulation: a UK approach

The paper outlines recent and ongoing research addressing the quantification of river flood frequencies at ungauged sites across Britain. The approach is one of modelling continuous time series of catchment runoff. Model parameters are established where data permit: the spatial generalisation to ungauged sites is effected by relating model parameters to widely available catchment properties whi...

Flood Estimation for a Cloudburst Event in an Ungauged Western Himalayan Catchment

Cloud burst is one of the reasons of flash flood in hilly regions. Such events are devastating as these induce landslides and boulder movement along with shooting velocity of water in hilly areas. This results in huge change of momentum and hence the large force. This force along with flood movement causes heavy loss of life and property. Cloudburst is a sudden aggressive rainstorm of small dur...

Volume-duration growth curves for flood estimation in permeable catchments

The volume and duration of groundwater discharge following extreme winter recharge events in permeable catchments can often be more disruptive than the peak discharge. An estimation procedure for annual maxima flood series in permeable catchments is extended to annual flood volumes for different durations. Growth factors for durations of 1 to 30 days and return periods of up to 250 years are de...
