Headcut retreat resulting from plunge pool erosion in a 3D landscape evolution model

Flores Cervantes, Javier Homero, 1977-Massachusetts Institute of Technology2004

Headcut retreat produced by plunge pools is represented using existing concepts about this type of erosion. The model estimates retreat rates, given flow, height of the headcut, upstream slope and Manning's roughness, and the relevant soil parameters (erodibility and critical shear stress). The …

Scour under air entrained jets below dams and flip buckets

Mason, P.J.City University London1987

… x, y and z. It was. surmised by the writer that plunge pool air entrainment could also be a relevant parameter and apparatus was built to examine this assumption. Two dimensional testing without air indicated scour to be independent of head drop (H) and directly proportional to flow (q), such …

Análisis de la lámina vertiente en el sobrevertido de presas de fábrica

Ortega Lara, Patricio Rubén2021

… jets and their effect on the pressures in the plunge pool located at the toe of the dam (for example, Castillo 2006 and Castillo et al. 2015). In this Doctoral Thesis an experimental analysis of the rectangular free-falling jets has been carried out. This characterization involves the analysis …
