The Uncertainty Cascade in Flood Forecasting
A methodology for propagating and constraining the uncertainty inherent in real-time flood forecasting is presented and demonstrated on an application to the River Severn, UK. The flood forecasting system is based on a cascade of rainfall-runoff and flood routing models, developed using stochastic transfer functions with state dependent parameterisations to allow for nonlinearity. The nonlinear...
متن کاملthe search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولUncertainty Analysis of Magnitude, Temporal and Spatial Distribution of Precipitation in Flood Forecasting
عدم قطعیت در بارش پیش بینی شده، یک منبع اصلی عدم قطعیت در پیش بینی بهنگام سیل می باشد. عدم قطعیت بارش از عدم قطعیت در مقدار بارش، توزیع زمانی و توزیع مکانی بارش تشکیل می شود. در این تحقیق به منظور پخش عدم قطعیت بارش در مدل پیش بینی سیل HEC-1 ، روش گسسته سازی زمانی در چهارچوب اصل بسط تئوری فازی و در ترکیب با الگوریتم ژنتیک نرمال بکار برده می شود. عدم قطعیت به علت توزیع زمانی ناشناخته بارش با ت...
متن کاملFuzzy and Hybrid Approaches to Modelling Uncertainty in Flood Forecasting
This paper reviews non-probabilistic approaches of modelling uncertainty, particularly in flood forecasting and introduces a fuzzy set theory-based method for treating precipitation uncertainty in rainfall-runoff modelling, which allows the temporal and/or spatial disaggregation of precipitation. The results of the fuzzy set theory-based method are compared with the probabilistic approach using...
متن کاملUncertainty in Calibrating Flood Propagation Models with Flood Boundaries Derived from Synthetic Aperture Radar Imagery
An instantaneous synthetic aperture radar (SAR) derived flood extent map helps retrieving the distributed conveyance parameters in one-dimensional flood routing models. These models are generally calibrated based on the sole use of ground data. This research aims to use earth observation (EO) data in order to establish a significant parameter retrieval strategy, providing an alternative model c...
