Bosa, Silvia; Petti, Marco - In: Water Resources Management 27 (2013) 6, pp. 1763-1779

exceeded 50 m. Although the phenomenon is clearly tridimensional, the application of a pure 3D hydraulic numerical model to … this wide and natural territory is very complicated. Recently, the authors have presented a numerical model of the impulse …:406–418, <CitationRef CitationID="CR4">2011</CitationRef>). In this paper, a 2DH numerical model has been applied to study the effects of …

A CFD Modeling Approach for Municipal Sewer System Design Optimization to Minimize Emissions into Receiving Water Body

Chen, Zhi; Han, Sangsoo; Zhou, Fa-Yi; Wang, Ke - In: Water Resources Management 27 (2013) 7, pp. 2053-2069

The design of the urban sewage system is site specific, and it makes the use of three-dimensional (3D) model an alternative to a field study or a laboratory experiment. However, the use of 3D computational fluid dynamics (CFD) in the study of the urban sewage system has been generally limited to...

Simulation of furrow irrigation using the Slow-change/slow-flow equation

Soroush, F.; Fenton, J.D.; Mostafazadeh-Fard, B.; … - In: Agricultural Water Management 116 (2013) C, pp. 160-174

A furrow irrigation model is developed based on the Slow-change/slow-flow routing equation, which is an approximate reduced form of the Saint-Venant equations to a single equation with a single variable, the upstream volume of water. For downstream-propagating disturbances it can be shown that...

Optimization of solar DHW system including PCM media

Haillot, Didier; Franquet, Erwin; Gibout, Stéphane; … - In: Applied Energy 109 (2013) C, pp. 470-475

The use of phase change materials (PCMs) to increase solar domestic hot water (SDHW) system efficiency has been already studied by different ways. Some studies place the storage material in the water tank, others directly in the solar thermal collector. However both of them show that the...

Tidal stream energy site assessment via three-dimensional model and measurements

Work, Paul A.; Haas, Kevin A.; Defne, Zafer; Gay, Thomas - In: Applied Energy 102 (2013) C, pp. 510-519

A methodology for assessment of the potential impacts of extraction of energy associated with astronomical tides is described and applied to a site on the Beaufort River in coastal South Carolina, USA. Despite its name, the site features negligible freshwater inputs; like many in the region, it...

Multifunctionality of Agriculture: An Inquiry Into the Complementarity Between Landscape Preservation and Food Security

Brunstad, Rolf Jens; Gaasland, Ivar; Vardal, Erling - European Association of Agricultural Economists - EAAE - 2005

Without support, the levels of agricultural public goods will fall short of the demand in high cost countries like Norway, Finland and Iceland. However, as demonstrated in this paper using Norway as a case, the current support and agricultural activity is far out of proportions from a public...
