Estimation of evaporation in Andalusian reservoirs: proposal of an index for th...
García-López, Santiago; Salazar-Rojas, Marcia; Vélez-Nicolás, Mercedes; Isidoro, Jorge; Ruiz-Ortiz, VerónicaStudy region: This study focuses on Andalusia (Southern Spain), a mediterranean region of 87,270 km2. Andalusia experiences significant water stress, making effective water management crucial. Study focus: Evaporation is a key element of the water budget, particularly in arid and semi-arid climates, where losses from reservoirs represent a significant fraction of the volume annually regulated and compromise the...
A multimethod interpolation approach for mapping the spatial distribution of ra...
Ruiz-Ortiz, Verónica; Maria Neto Paixão Vazquez Fernandez Martins, Helena; Granja Martins, Fernando Miguel; Vélez-Nicolás, Mercedes; Isidoro, JorgeEight spatial interpolation models were used to map the spatial distribution of precipitation in the southwestern sector of the Iberian Peninsula (22330 km2) over 40 years (1980/1981-2019/2020). Rainfall data from 103 meteorological stations were used to generate the interpolation models, namely inverse distance weight (IDW) with 6, 12 and 24 points, regression spline (RS), thin spline (TS), universal kriging w...
Mapping the spatial variability of rainfall from a physiographic-based multilin...
Ruiz-Ortiz, Verónica; G. P. Isidoro, Jorge M.; Fernandez, Helena Maria; Granja-Martins, Fernando M.; García-López, SantiagoA physiographic-based multilinear regression model supported by GIS was developed to estimate spatial rainfall variability in the Southwest Iberian Peninsula. The area study includes a wide diversity of landscape features and comprises four Portuguese regions and one Spanish province (totalizing 28,860 km(2)). The region suffers a very strong Mediterranean influence, with a major cleavage between winter and sum...
