Application of Artificial Neural Networks for Flood Forecasting
In hydrology, as in a number of diverse fields, there has been an increasing use of Artificial Neural Networks (ANN) as black-box simplified models. This is mainly justified by their ability to model complex non-linear patterns; in addition they can self-adjust and produce a consistent response when ‘trained’ using observed outputs. This paper utilises various types of ANNs in an attempt to ass...

Floods are among the natural disasters that cause human hardship and economic loss. Establishing a viable flood forecasting and warning system for communities at risk can mitigate these adverse effects. However, establishing an accurate flood forecasting system is still challenging due to the lack of knowledge about the effective variables in forecasting. The present study has indicated that th...

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 کاملApplication of Remote Sensing Data to Constrain Operational Rainfall-Driven Flood Forecasting: A Review
Fluvial flooding is one of the most catastrophic natural disasters threatening people’s lives and possessions. Flood forecasting systems, which simulate runoff generation and propagation processes, provide information to support flood warning delivery and emergency response. The forecasting models need to be driven by input data and further constrained by historical and real-time observations u...
متن کاملFlood Forecasting Using Neural Networks
This paper deals with flood routing in rivers using neural networks. The unsteady river flow may be formulated in terms of two one-dimensional partial differential equations. These are the Saint Venant flow continuity and dynamic equations. Several methods of solution of these equations are known. These methods are based upon characteristics of equations, finite difference, finite element and f...
