Modelo hidrodinámico completo para riego por melgas

Tecnología y ciencias del agua, 2011
Se presenta un modelo numérico para riego por melgas basado en el acoplamiento interno de las ecuaciones de Saint-Venant y Richards, el cual permite describir las fases de avance, almacenamiento, consumo y recesión del riego por melgas.

Evaluating the effects of preprocessing, method selection, and hyperparameter tuning on SAR-based flood mapping and water depth estimation [PDF]

Natural Hazards and Earth System Sciences
Flood mapping and water depth estimation from Synthetic Aperture Radar (SAR) imagery are crucial for calibrating and validating hydraulic models. This study uses SAR imagery to evaluate various preprocessing (especially speckle noise reduction), flood ...

Sulla sesta distorsione elementare di Volterra per un cilindro cavo omogeneo e isotropo di altezza finita con carico alla Saint Venant

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2008
In this work we consider the sixth elementary Volterra's distortion for a circular hollow, homogeneous, elastic, isotropic cylinder, to analyze the load acting on the bases as a Saint Venant characteristic external stress.

Formal derivation of a new sediment transport model using a multiscale procedure: Numerical Validation

Partial Differential Equations in Applied Mathematics
We study in this work structures formed under a unidirectional flow. The main problem that addresses sediment transport by aquatic flow. We present the formal derivation of a new sediment transport model by using a multiscale procedure in time and space.

SAINT-VENANT TYPE ESTIMATE FOR THE WAVE EQUATION

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2002
Bu çalışmada hızı azalan bir dalga denklemi için Uzaysal Azalım Kestirimi elde edilmiştir. Yük bölgesinden uzaklaşıldıkça son etkilerin, en azından kısa zaman aralıkları için çok hızlı bir şekilde azaldığı görülmüştür.

A new model for shallow viscoelastic free-surface flows forced by gravity on rough inclined bottom

ESAIM: Proceedings and Surveys, 2014
A thin-layer model for shallow viscoelastic free-surface gravity flows on slippery topographies around a flat plane has been derived recently in [Bouchut-Boyaval, M3AS (23) 2013]. We show here how the model can be modified for flows
