Interactions between dry-air entrainment, surface evaporation and convective boundary-layer development [PDF]

The influence of dry-air entrainment on surface heat fluxes and the convective boundary-layer (CBL) properties is studied for vegetated land surfaces, using a mixed-layer CBL model coupled to the Penman¿Monteith equation under a wide range of conditions.

Bepalen Penman-Monteith gewasweerstanden : Gestandaardiseerde conversie van Makkink-gewasfactoren naar Penman-Monteith gewasweerstanden, documentatie R-script en toepassing voor het NHI

Het Nationaal Hydrologisch Instrumentarium (NHI) bevat data, modelcodes en tools voor het modelleren van het watersysteem in Nederland. De stroming van water in de onverzadigde zone kan worden gemodelleerd met (Meta)SWAP. Het gedrag van het grondwater in de onverzadigde zone hangt af van de verdamping door gewassen en vice versa. In de huidige modellen
