An urban flood simulation model based on TELEMAC-2D was constructed, and the inundation data of two measured rainstorms (7 June 2018 16 September 2018) were selected to validate model. Flooding processes simulated under 12 designed rainfall scenarios with return periods 20, 50 100 years peak coefficients 0.2, 0.4, 0.6 0.8, respectively. The hazard-vulnerability (H-V) method used for risk assess...

Complex, high resolution, finite-element TELEMAC-2D grids have been developed to simulate ocean/fluvial interaction in three shallow, intensively managed Welsh estuaries. In each case, important ecosystems and developed areas are exposed to flooding from both tidal and fluvial events. Of particular concern is how the estuaries will be affected by future sea-level rise due to climate change, and...

The presence of impermeable surfaces in urban areas hinders natural drainage and directs the surface runoff to storm systems with finite capacity, which makes these prone pluvial flooding. occurrence flooding depends on existence minimal for generation concentration. Detailed hydrologic hydrodynamic simulations are computationally expensive require intensive resources. This study compared evalu...

The rich biodiversity in the floodplain area is influenced by both floods and groundwater (GW). To protect ecological environment area, it essential to study interaction between GW. objective of this paper propose a coupling strategy hydrodynamic model GW provide an accurate simulation tool for quantifying case conducted middle reaches Irtysh River northwest China. Firstly, two-dimensional base...

An accurate assessment of the hydro-environmental impacts tidal range energy schemes, where performance scheme has an impact on marine environment and ecology, is crucial in optimising design development such schemes. A proposal for a new coastally-attached impoundment, namely West Somerset Lagoon, been investigated this research numerical model TELEMAC-2D refined to theimpacts Bristol Channel ...
