Can Flash Flood Risk Index Be an Early Warning Signal of Flash Floods in Ungauged Basin?
Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.ABSTRACT Flash flooding is amongst the most severe natural hazards, causing widespread socioeconomic impacts across both wet regions and drylands. In ungauged mountainous basins, effective risk warning based on hydrodynamic modelling is challenging due to sparse hydrological observations and complex terrain.

Experimental investigation of low-angle dune morphodynamics
E3S Web of Conferences, 2018 Dunes commonly dominate the bed of sandy rivers and they are of central importance in predicting flow resistance and water levels. In the present study, we show that by using light-weight polystyrene particles as substrate in a laboratory setting ...

Convective nature of planimetric instability in meandering river dynamics [PDF]
, 2006 The convective nature of the linear instability of meandering river dynamics is analytically demonstrated and the corresponding Green's function is derived. The wave packet due to impulsive disturbance migrates along a river either downstream or upstream,

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Accurate data on curvature‐induced water‐surface superelevation are important for understanding complex patterns of fluid motion in meandering rivers. Nevertheless, superelevation has been studied primarily in the laboratory because field measurements are difficult to obtain.

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract This study analyzes laboratory data of beach response to sea‐level rise (SLR), isolating shoreline changes driven by passive flooding (PF) of the beach and consequent wave‐driven processes. The disequilibrium concept relates shoreline change to instantaneous and equilibrium beach states. While PF shifts the shoreline geometrically, SLR induces

Long-term and large-scale modeling of mega-nourishments [PDF]
, 2016 The Sand Engine, ZM (Zandmotor), is a hook-shaped mega-nourishment (21.5 millions m³) located on the Dutch coast with an alongshore length of 2.4 km and an offshore extension of 1 km.

3D layer-integrated modelling of morphodynamic processes near river regulated structures [PDF]
, 2016 Sedimentation and erosion can significantly affect the performance of river regulated reservoirs. In the vicinity of flow control structures, the interaction between the hydrodynamics and sediment transport often induces complex morphological processes ...

Beyond Water: Mapping Sediment Bars to Enhance Satellite Monitoring of River Dynamics
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Unvegetated sediment bars are central to river morphodynamics but are rarely used as indicators of channel dynamicity in satellite‐based studies. Linking sediment dynamics and river lateral mobility requires monitoring sustained changes in both water and sediment—the active channel (AC)—to avoid stage‐dependent noise.

Fish zoning of some watercourses in Normandy [Translation from: Verhandlungen der Internationalen Vereinigung fuer Theoretische und Angewandte Limnologie 18, 1135-1146, 1972] [PDF]
, 1977 The identification of fish zones in western and central Europe has been the objective some major studies. This paper concerns a stream in Normandy specially studied by the author in 1969 and 1970 in the framework of a study on the role of the mean ...

Statistical characterization of spatio-temporal sediment dynamics in the Venice lagoon [PDF]
, 2016 Characterizing the dynamics of suspended sediment is crucial when investigating the long-term evolution of tidal landscapes. Here we apply a widely tested mathematical model which describes the dynamics of cohesive and noncohesive sediments, driven by ...
