Adaptation of the FAO´s method to assess real evapotranspiration in the SHALL hydrological simulation model

Considering the predominance of the vertical direction in the exchange flows between hydrological components of the plain systems and, consequently, the preponderance of evapotranspiration as a process, an adaptation of the methodology proposed by FAO to the variables used by the SHALL hydrological...

description Considering the predominance of the vertical direction in the exchange flows between hydrological components of the plain systems and, consequently, the preponderance of evapotranspiration as a process, an adaptation of the methodology proposed by FAO to the variables used by the SHALL hydrological model is presented. This model is suitable for continuous simulation in plain areas. The model is quasi-3D hydrodynamic, which considers the underground and surface components of water flows, together with the vertical flows towards the aquifer and the atmosphere. The model has been applied in open systems in the south of Santa Fe province and closed systems in the La Pampa province and is currently being implemented in depressed areas of Buenos Aires province. For the adaptation, an estimate of extreme effective saturation is proposed according to the moisture retention curves adjusted with Brooks-Corey formula. Following the guidelines of the publication FAO No. 56, an estimate of the effective limit saturation is presented for which, below it, the vegetal covers begin to restrict the supply of potential evapotranspiration, and the coefficient of hydric stress based on the calculated limit saturations, to estimate, finally, the real evapotranspiration based on variables contemplated by the SHALL model components.

Considerando la predominancia del sentido vertical en los flujos de intercambio entre componentes hidrológicos de los sistemas de llanura y, consecuentemente, la preponderancia de la evapotranspiración como proceso, se presenta una adaptación de la metodología propuesta por FAO a las variables empleadas por el modelo hidrológico SHALL, apto para simulación continua en áreas de llanura. El modelo es hidrodinámico cuasi-3D, que contempla las componentes subterránea y superficial de flujos de agua, conjuntamente con los flujos verticales hacia el acuífero y la atmósfera. El modelo ha sido aplicado en sistemas abiertos del sur santafesino y en sistemas cerrados pampeanos y actualmente se está implementando en áreas deprimidas bonaerenses. Para la adaptación se propone una estimación de saturaciones efectivas extremas conforme a las curvas de retención de humedad ajustadas con la fórmula de Brooks-Corey. Siguiendo los lineamientos de la publicación FAO N° 56, se presenta una estimación de la saturación efectiva límite para la cual por debajo de la misma las coberturas vegetales comienzan a restringir el abastecimiento de la evapotranspiración potencial, y del coeficiente de estrés hídrico en función de las saturaciones límites calculadas, para estimar, finalmente, la evapotranspiración real en función de variables que contempla el modelo SHALL.
