The recent requirements of Spanish regulations and directives, on their turn based European have led to the development a new two dimensional open channel flow modelling tool. tool, named Iber, combines hydrodynamic module, turbulence module sediment transport is in finite volume method solve involved equations. simulation code has been integrated pre-process post-process interface GiD software, developed by CIMNE. result system for rivers estuaries that uses advanced numerical schemes,...
In this paper, the results of a benchmark test launched within framework NSF–PIRE project "Modelling Flood Hazards and Geomorphic Impacts Levee Breach Dam Failure" are presented. Experiments two-dimensional dam-break flows over sand bed were conducted at Université catholique de Louvain, Belgium. The water level evolution eight gauging points was measured as well final topography. Intense scour occurred close to failed dam, while significant deposition observed further downstream. From these...
Two‐dimensional shallow water models are widely used tools for flood inundation mapping. However, even if High Performance Computing techniques have greatly decreased the computational time needed to run a 2D model, this approach remains unsuitable applications that require results in very short or large number of model runs. In paper we test non‐parametric regression based on least squares support vector machines as computationally efficient surrogate equations The methodology is initially...
Dual urban drainage models allow users to simulate pluvial flooding by analysing the interaction between sewer network (minor system) and overland flow (major system). This work presents a free distribution dual model linking Iber Storm Water Management Model (SWMM), which are 2D 1D model, respectively. The methodology consists in step calling process from Dynamic-link Library (DLL) that contains functions SWMM code is split. involves validation of simplified street, full-scale physical real...
Modelling hydrological processes with fully distributed models based on the shallow water equations implies a high computational cost, which often limits resolution of mesh. Therefore, in practice, modellers need to find compromise between spatial resolution, numerical accuracy and cost. Moreover, this balance is probably related underlying Digital Terrain Model (DTM). In work, it studied effect DTM size mesh results runtime model 2D equations. Seven rainfall events four different basins...
Data assimilation (DA) in physically-based hydrodynamic models is conditioned by the difference temporal and spatial scales of observed data resolution model itself.
