Simulating Levee Erosion with Physical Modeling Validation
This paper studies rill and gully initiation and propagation on levees, dams, and general earth embankments. It specifically studies where these erosion features occur, and how long a particular embankment can sustain overtopping before breaching and catastrophic failure. This contrasts to previous levee erosion analysis, which has primarily concerned the final effects of erosion, such as soil ...
متن کاملSimulation of Levee Erosion
In this report, I talk about my work on fluid simulation and erosion simulation. First some background knowledge about both fluid and hydraulic erosion simulation is discussed and then some technical details about a levee erosion simulator is presented. Some implementation results of the system are also presented and discussed. Finally, I will also discuss the difficulties I faced when doing th...
متن کاملAnalysis of hydrofoil craft in regular and irregular waves
In this article, the most important specifications of hydrofoil floats, i.e. their seakeeping under regular and irregular waves under different encounter angles of wave, has been investigated. Numerical simulation has been done using STAR CCM+ software. Surge, heave, roll and pitch motions are kept free at the same time and their effects on each other are taken into account. USV01 model, whose ...
متن کاملAdded Resistance & Drift Force Analysis in Regular and Irregular Waves
The sea wave causes excess resistance which is out of scope of calm water resistance. The total wave force in horizontal plane is divided into “Added Resistance” and “Drift Force”. In this study, based on Gerritsma and Beuckelman[3] hypothesis a computer program has been developed for calculation of added resistance and drift force at various ship speeds and various head...
متن کاملIonospheric erosion by Alfvén waves
Abstract: Using observations from the FAST small explorer spacecraft we present fields and plasma observations above the dayside auroral oval showing the erosion of ionospheric plasmas from the topside ionosphere by the action of Alfvén waves. Using interferometric techniques the waves are shown to approximately obey the expected dispersion for Alfvén waves with transverse scales extending from...
