In this paper, we present a novel technique for the objective detection of the
geomorphological effects of flooding in riverbeds and floodplains using imagery acquired by …

The numerical modelling of 2D shallow flows in complex geometries involving transient flow
and movable boundaries has been a challenge for researchers in recent years. There is a …

A GPU-parallel numerical model for the solution of the 2D Shallow Water Equations, based
on a novel type of grid called Block-Uniform Quadtree (BUQ), is presented. BUQ grids are …

The National Oceanic and Atmospheric Administration (NOAA) National Centers for
Environmental Information (NCEI) generates digital elevation models (DEMs) that range …

The challenge of finding a compromise between computational time and level of accuracy
and robustness has traditionally expanded the use simplified models rather than full two …

Coupled 1D–2D numerical strategies are presented in this work for their application to fast
computation of large rivers flooding. Both 1D and 2D models are built using explicit upwind …

The description of the floods which have occurred in the past and an assessment of the
adverse impacts they have entailed are among the duties required by the European Flood …

Droughts reduce freshwater availability and have negative environmental, economic, and
social impacts. In estuaries, the dynamics between the saltwater and the freshwater can be …

A pluvial flash flood is rapid flooding induced by intense rainfall associated with a severe
weather system, such as thunderstorms or typhoons. Additionally, topography, ground cover …

Computational tools may help engineers in the assessment of sediment transport during the
decision-making processes. The main requirements are that the numerical results have to …
