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...
متن کاملFlood Risk from Extreme Events
There is increasing evidence that more frequent flooding resulting from increases in the frequency and intensity of storms are likely to be one consequence of anthropogenic climate change in many parts of the world including the United Kingdom. Flooding in the UK is currently a major and costly environmental hazard with annual damage from floods of around £1 billion at present levels of protect...
متن کاملFlood Hydrograph Simulation with Uncertainty in Rainfall - Runoff Parameters
Flood hydrograph simulation is affected by uncertainty in Rainfall – Runoff )RR( parameters. Uncertainty of RR parameters in Gharasoo catchment, part of the great Karkheh river basin, is evaluated by Monte–Carlo (MC) approach. A conceptual-distributed model, called ModClark, was used for basin simulation, in which the basin’s hydrograph was determined using the superposition of runoff generated...

متن کاملCalibration of a conceptual rainfall-runoff model for flood frequency estimation by continuous simulation
An approach is described to the calibration of a conceptual rainfall-runoff model, the Probability Distributed Model (PDM), for estimating flood frequencies at gauged sites by continuous flow simulation. A first step was the estimation of routing store parameters by recession curve analysis. Uniform random sampling was then used to search for parameter sets that produced simulations achieving t...
