Boulder deposition during major tsunami events
  • Algarve ; Boulder ; Coastal environment ; Eighteenth Century ; Hydrodynamics ; Modelling ; Palaeogeography ; Portugal ; Sediment transport ; Tsunami
  • indicates that abrasion during transport and redeposition was not significant. The AA. envisage boulder deposition as having taken place during the Lisbon tsunami of AD 1755. The AA. use numerical hydrodynamic modeling of tsunami (and storm) waves to test

Real-time measurement and preliminary analysis of debris-flow impact force at Jiangjia Ravine, China
  • Carrying capacity ; China ; Debris flow ; Grain size distribution ; Hydrodynamics ; Impact ; Natural hazards ; Risk management ; Watershed ; Yunnan
  • . Analysis of the impact force of 38 debris flow surges gives an empirical value for the ratio of the hydrodynamic pressure to the momentum flow density, i.e. the product of debris-flow density and mean velocity square, which provides a very valuable basis

Long-term morphological impacts of the opening of a new inlet on a multiple inlet system
  • This study focuses on the dominant Faro-Olhão and Armona inlets in the Ria Formosa barrier island system of southern Portugal. The equilibrium state and future evolution of the system are inferred using a range of morphological and hydrodynamic

Influence of grass soil cover on water runoff and soil detachment under rainfall simulation in a sub-humid South African degraded rangeland
  • In order to understand the evolution of hydrodynamics and detachment soil rate with different stages of degradation of a rangeland by overstocking, two rainfall simulations were conducted on 1 m2 experimental plots in an abandoned cultivated South

A two-dimensional morphodynamic model of gravel-bed river with floodplain vegetation
  • In this paper account is taken of the effects of riparian and floodplain vegetation on bank strength, floodplain flow resistance, shear stress partitioning, and bedload transport. This is incorporated into an existing 2D hydrodynamic-morphological

Nonlinearity and unsteadiness in river meandering : a review of progress in theory and modelling
  • . Hence they first derive a classification of river bends based on a systematic assessment of the various physical mechanisms affecting their morphodynamic equilibrium and their evolution in response to variations of hydrodynamic forcing. They then review
