Inundation models based on the Shallow Water Equations (SWE) have been shown to perform well for a 3 wide variety of situations even at the limit of their theoretical applicability and, arguably, somewhat beyond. One of 4 these situations is the catastrophic event of floods induced by dyke breach and consequent dyke erosion. The dyke 5 collapse is often not sudden as assumed by many flood simul...

This paper analyses a set of velocity time histories which were obtained at a fixed point in the bottom boundary layer of a tidal stream, 5 m from the seabed, and where the mean flow reached 2.5 m s(-1). Considering two complete tidal cycles near spring tide, the streamwise turbulence intensity during non-slack flow was found to be approximately 12-13%, varying slightly between flood and ebb ti...

flood routing has many applications in engineering projects and helps designers in understanding the flood flow characteristics in river flows. floods are taken unsteady flows that vary by time and location. equations governing unsteady flows in waterways are continuity and momentum equations which in case of one-dimensional flow the saint-venant hypothesis is considered. dynamic wave model as ...

The paper presents the state-of-the-art in flood forecasting and simulation applied to a river flood analysis and risk prediction. Different water flow forecasting and river simulation models are analysed. An advanced river flood forecasting and modelling approach developed within the ongoing project INFROM is described. It provides an integrated procedure for river flow forecasting and simulat...

We used an annual time series (August 2004 until August 2005) of ENVISAT-ASAR data, supported by two ASTER scenes to investigate ice dam fluctuations and changes of the surface area of the marginal lake Grænalón. The lake occupies a lateral valley, dammed by the westernmost flow band of Skeiðarárjökull, one of the largest outlets of Vatnajökull ice cap. During the period of investigation Skeiða...
