The Muskingum method is one of the widely used methods for lumped flood routing in natural rivers. Calibration its parameters remains an active challenge researchers. task has been mostly addressed by using crisp numbers, but fuzzy seems a reasonable alternative to account parameter uncertainty. In this work, model proposed where assessment outflow as quantity based on linear with inputs. This ...

This study presents an advanced remote sensing-based steady-state flood model to improve flood management strategies. The REFIX (Regression and Elevation based Flood Information eXtraction) model is based on regression analysis and uses a remotely sensed flood extent and a high-resolution floodplain DEM (Digital Elevation Model) to estimate water heights for a given flood event. In some cases, ...

Abstract An approach is presented for directly deriving a variable parameter Muskingum method from the St. Venant equations for routing floods in channels having any shape of prismatic cross-section and flow following either Manning's or Chezy's friction law. The approach also allows the simultaneous computation of the stage hydrograph corresponding to a given inflow or the routed hydrograph. T...

The main approach to design flood estimation in Australia is event-based with the use of flood hydrograph models such as RORB, WBNM and URBS the most common practice for estimating design floods via rainfall based approaches. A characteristic of these models is that the routing of rainfall excess is distributed within the catchment, the amount of routing depending on the amount of sub-division ...
