Intercepted rainfall in Valladolid city
Description
When rain falls on to a vegetated surface (gross rainfall), a part is intercepted by the canopy and evaporated directly back into the atmosphere (interception loss). The remainder of the rainfall reaches the ground (net rainfall) both through gaps and by dripping from the canopy (through fall), or by running down the main stem (stem flow). The canopy storage capacity is the minimum amount of water necessary to completely saturate the canopy surface. The maximum storage capacity of a leaf ranges from 1 to 2 l/m2. In case of a low rainfalls (<5 mm/m2), the intercepcion capacity and the rainfall are similar. For a heavier rainfall, the interception is about 10% of the precipitation. In a simplified mode, the interception can be calculated as the product of the rainfall and a coefficient α, which depends on the type of vegetation cover. In wet areas with a huge vegetated cover, α varies from 0.1 to 0.2 and its is 0 in arid regions.
