“…Hydrographic basins constitute territorial units of management where the climatic characteristics are directly related to the hydrological and environmental effects, as a consequence of rainfall (González‐Hidalgo et al, ; García‐Barrón et al, ). Due to its complex topography, the Iberian Peninsula is divided into hydrographic basins that show geographic areas with different meteorological traits (Martin‐Vide and Olcina, ).…”

Understanding the intra‐annual distribution of rainfall is an important element for climatic classification and serves as a basis for natural resources management. The present study analyses multi‐annual irregularities of the rainfall distribution throughout the year in the period 1941–2010, in the hydrographic basins of the Iberian Peninsula. In order to analyse its variation, the rainfall centralisation and dispersion parameters throughout the annual cycle were previously defined and calculated for each year. Inter‐annual series of both parameters were generated, which allowed detecting their temporal behaviour in each of the basins and relating differentiated geographic areas. Independent of the total annual rainfall, greater temporal simultaneity is observed in the fluctuations of the intra‐annual parameter ‘centralisation’ in the Atlantic basins and wider inter‐annual oscillations in the Mediterranean basins. Around the year 1970, there was a displacement in the predominance of autumn rains, although the process is inverted in the last decades. Also from the decade of 1970 there is a general increase in the inter‐annual variability of the ‘dispersion’ parameter, especially in the basins that drain towards the Atlantic Ocean. The ‘dispersion’ parameter allows detecting latitudinal (Cantabrian vs. Guadalquivir) and longitudinal (Atlantic vs. Mediterranean) patterns of intra‐annual rainfall distribution irregularity in the Iberian Peninsula. The results obtained are also associated to atmospheric general circulation patterns of the North Atlantic Oscillation and the Western Mediterranean Oscillation. The monthly winter values of the North Atlantic Oscillation present a marked influence on dispersion, especially in the basins that discharge into the Atlantic Ocean, which show a double gradient: decreasing longitudinally from the Atlantic coast to the Mediterranean coast and latitudinally from north to south.

“…Mediterranean climate, as referred earlier, presents a strong intra-and inter-annual irregularity, being especially evident in the rainfall patterns [49]. Additionally, studies of hydrological behavior in Mediterranean climate using precipitation and discharge averages are not relevant, since this kind of climate is dominated by extreme events [50].…”

The study watershed is located within the Idanha Irrigation Scheme, Portugal. A hydrological and water quality station was installed at the outlet of the catchment. The AnnAGNPS model was applied in this study, and afterwards it was calibrated and validated to the conditions in the study catchment. The antecedent soil moisture conditions play an important role for rapid runoff and flash flooding. Relative Water Supply (RWS) is always bellow the unity value and sometimes below the value 0.5. Sometimes in very dry years, like the year 2004-2005 (302 mm), a runoff coefficient is equal to 0.40. Spatial distribution of runoff was primarily influenced by topography and soil management, which is common in Mediterranean agricultural systems, namely in grain crop systems such as oats and wheat. The simulation of spatial distribution of nitrate load shows a dependence of the spatial distribution of runoff, due to its high solubility. Spatial distribution of soil erosion by water indicates that the process does not depend directly on the runoff distribution in the catchment. Therefore, soil erosion is greatly influenced by deficient land cover whenever erosivity of rainfall is strong. Phosphorus losses were less than nitrate losses, due to their lower water solubility and mobility in soil.
