Laser Profiler (LP) data from aerial laser surveys have been increasingly used as topographical inputs to numerical simulations of flooding and inundation in river basins. LP data has great potential for reproducing topography, but its effective usage has not yet been fully established. In this study, flooding and inundation are simulated numerically using LP data for the Jobaru River basin of ...

Relief relative to a local elevation maximum provided a strong indicator of inundation dynamics (i.e., hydroperiod), but was less useful for mapping wetland boundaries. Combining local relief and an Enhanced Topographic Wetness Index produced a map that was well suited for mapping wetland extent and hydroperiod. Wetlands mapped using aerial photographs or LiDAR-derived digital elevation models ...

Unlike for the instrument of hazard zone maps for surface waters, there is no common approach for the calculation of inundation risk caused by spontaneous overland runoff. For being able to assess the associated potential damage, the maximum inundation depth is being calculated via an extended 2D flow model, based on a rain event with an 100-year return period and a duration of 60 minutes. The ...

We provide preliminary calculations of wave generation, propagation and inundation for the December 26, 2004 Indian Ocean tsunami. Calculations are based on Boussinesq model FUNWAVE and are carried out on a Cartesian grid with spatial resolution comparable to 2 minutes in latitude and longitude. Initial conditions are provided by the TOPICS model and are based on estimates of ground motion in f...

Surveys of the physical aspects of landfalling tropical cyclones are important for at least three reasons: (a) to test the veracity of numerical surge models by comparison with topographically surveyed debris lines that mark the level of marine inundation, along with records from tide gauges; (b)to determine the relative contributions of surge, tide, wave action and wave run-up to the total mar...

Dhaka-Narayanganj-Demra (DND) Project is one of about 700 water sector projects built by Bangladesh Water Development Board (BWDB) in Bangladesh. It was a successful project from all considerations. But during 1998 flood, there was overtopping and breaching of embankment. At that time BWDB was able to stop much inundation by doing emergency work. Still many people are building their houses and ...

Riverbank filtration schemes form a significant component of public water treatment processes on a global level. Understanding the resilience and water quality recovery of these systems following severe flooding is critical for effective water resources management under potential future climate change. This paper assesses the impact of floodplain inundation on the water quality of a shallow aqu...
