Advances in real-time flood forecasting.
This paper discusses the modelling of rainfall-flow (rainfall-run-off) and flow-routeing processes in river systems within the context of real-time flood forecasting. It is argued that deterministic, reductionist (or 'bottom-up') models are inappropriate for real-time forecasting because of the inherent uncertainty that characterizes river-catchment dynamics and the problems of model over-param...
متن کاملFlood Forecasting in CrossGrid Project
This paper presents a prototype of flood forecasting system based on Grid technologies. The system consists of workflow system for executing simulation cascade of meteorological, hydrological and hydraulic models, data management system for storing and accessing different computed and measured data, and web portals as user interfaces. The whole system is tied together by Grid technology and is ...
متن کاملMutual Inclusion in Flood Forecasting
Mutual exclusion is directly related to a host of selections at both system and component levels; is responsible for diversification; and gives rise to uniqueness. Mutual exclusion is also evident in modelling and flood forecasting, be it in models, software tools, data, modelling practices, flood forecasting and warning issues, and management systems. The emerging picture is that (i) diversity...
متن کاملRecent Advances in the Development of Flood Forecasting and Warning Services in Australia
The Australian Bureau of Meteorology is the lead national agency for flood forecasting and warning services in Australia, working in partnership with agencies at the State and Local Government levels. These services cover river basins with response times ranging from 6-12 hours through to very large basins with flood travel times of the order of weeks. Flash flood warning services are also prov...
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...
