| description | The interception of rainfall by vegetation greatly affects the hydrology of a basin.
The main objective of this paper is to evaluate the effect of annual rainfall variability on
the interception in isolated individuals of two of the most common types of vegetation,
Pinus pinea and Cistus ladanifer, in a Mediterranean watershed. For this, experimental
data were taken for four years and the Rutter interception model was used to calculate the
canopy drying time, while Rutter and Klaassen methodologies were used to determine
the storage capacity of the canopy. On the whole, 29.6% of rainfall was intercepted
for pine, and 17.7% for rockrose. Stemflow accounted for 0.3% for pine and 17% for
rockrose, while 70.1% of the rainfall fell as throughfall for pine and 65.3% for rockrose.
However, in dry years, the interception percentage almost doubled that of wet years.
An average canopy drying time of 9.2 hours was established for pine, and 4.4 hours for
rockrose. Approximately equal results of canopy storage capacity were obtained from
both methods (1.8 mm for pine and 0.7 mm for rockrose). Both species registered higher
values of canopy storage capacity in dry years than in wet years. |

El objeto de este trabajo es determinar el efecto de la variabilidad anual de la lluvia sobre la interceptación en individuos aislados de Pinus pinea y Cistus ladanifer, en una cuenca mediterránea. Para ello, se tomaron datos experimentales durante cuatro años y se usó el modelo de interceptación de Rutter para calcular el tiempo de secado del dosel, en tanto que para determinar la capacidad de almacenamiento del dosel se consideraron las metodologías de Rutter y Klaassen. En conjunto, el 29,6% de la lluvia fue interceptada por pino y 17,7% por jara. El 0,3% en pino y el 17% en jara ocurrió como escorrentía cortical, y el 70,1% fue trascolación en pino y el 65,3% en jara. Sin embargo, en años secos, el porcentaje de interceptación casi duplicó el de años húmedos. El tiempo de secado medio en pino fue 9,2 horas y en jara 4,4. Aproximadamente, se obtuvieron iguales resultados de la capacidad de almacenamiento del dosel usando ambos métodos (1,8 mm en pino y 0,7 en jara), registrándose también valores más altos en años secos.
