The interaction between plant hydraulics and plant structure was documented by Leonardo da Vinci, and its importance as a regulator of vegetation and ecosystem function remains of vital contemporary interest. It is proposed that hydraulics deter[...]

This paper presents a depth-averaged two-dimensional shallow water model for simulating long waves in vegetated water bodies under breaking and non-breaking conditions. The effects of rigid vegetation are modelled in the form of drag and inertia[...]

Due to increased flood discharges during the past years, overtopping of dikes and earthen embankments has caused large damages to the surrounding infrastructure and the environment. Despite the numerous dike breaches and the high damage potentia[...]

The numerical model BASEMENT, based on the two-dimensional shallow-water equations, is applied to breaching processes of non-cohesive earth embankments due to overtopping. The governing equations are solved using an explicit finite-volume method[...]

A two-dimensional (2D) depth-averaged model is developed for simulating unsteady turbulent shallow-water flows with dry–wet fronts (e.g. dam-break flow). The model is based on 2D depth-averaged Reynolds-averaged Navier stokes equations coupled w[...]

This work presents a novel numerical solution of nonlinear shallow water equations involving moving waterlines. A hybrid Lagrangian–Eulerian mapping technique was proposed to account for two simultaneous shorelines fluctuating over dry beds. In [...]

A novel method for the reduction of wave height along the outer wall of a bend is introduced by adding a convex corner to the inner bend wall. The negative waves emitted from the convex corner are then superimposed on the positive waves caused b[...]

A research undertaken to determine the behaviour of supercritical flow in sewer junction manholes is summarized with an emphasis on small discharge structures. A physical model was implemented to test various configurations. The independent vari[...]

Herein, scour depth measurements are compared with theoretical and empirical estimates obtained at four sites in Chiba and Fukushima Prefectures impacted by the 2011 Tohoku Tsunami. At sites where scour was caused by either floodwall overtopping[...]
