Resumo: Simulation results for water content dis­tribution obtained with HYDRUS, RZWQM and MOHIDLAND models were compared with field data. These models differ mainly in calculating root water uptake and computing crop water requirements. Simulations were carried out in different horizons of an Hortic An­throsol and an Eutric Fluviosol, located in the Alentejo region (Portugal). Soil water content was measured, with a TDR sys­tem at different depths. Soil hydraulic properties were determined in the labora­tory, and described in HYDRUS and MOHIDLAND with the Mualem-van Genuchten, and in RZWQM with the modified Brooks and Corey equations. Reference evapotranspiration was calcu­lated with the Penman-Monteith and the Shuttleworth-Wallace method using at­mospheric data from the meteorological stations located near the field plots. Parti­tion between transpiration and evapora­tion was calculated using the Leaf Area Index values, and the RZWQM crop module. Results show a good agreement between model simulations and field measurements for the three models.

Estes mode­los diferem principalmente nos cálculos da extracção de água pelas raízes e das neces­sidades de água das plantas. As simulações foram realizadas para diferentes profundi­dades de um Fluvissolo Êutrico e de um Antrosolo Hórtico localizados no Alentejo (Portugal). O teor de água foi medido com um sistema TDR. As propriedades hidráuli­cas, determinadas laboratorialmente, foram descritas com as equações de Mualem-van Genuchtene e Brooks and Corey modifica­das. A evapotranspiração de referência foi calculada com os métodos de Penman-Monteith e de Shuttleworht-Wallace com dados atmosféricos medidos. A partição entre a transpiração das plantas e a evapora­ção do solo foi calculada através do Índice de Área Foliar medido e através do modelo RZWQM. Os resultados mostram boa con­cordância entre as simulações dos três modelos e os valores de campo.Sociedade de Ciências Agrárias de Portugal2018-12-04T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.19084/rca.15846eng2183-041X0871-018XBarão, L.Leitão, P.
