Ensayo de correlación entre los parámetros geofísicos e hidrológicos de los depósitos volcánicos de la Caldera de Bandama (Gran Canaria)

[EN]The geometry and the hydraulic conductivity of the unsaturated zone is difficult to study from traditional techniques, like samples from trenches that normally provide surficial data or boreholes, that are expensive and provide local information. Non-destructive geophysical techniques and among them the electrical resistivity tomography method can be applicable in volcanic areas, where the lava flows and pyroclastic deposits have a wide range of values depending on the degree of fracturing and weathering of lava flows, and porosity and texture of the pyroclastic deposits. In order to characterize the subsurface geology below the golf course of Bandama (Gran Canaria) has conducted a campaign of electrical resistivity tomography profiles.

Application of evolutionary algorithms and the boundary element method in the optimization of noise barrier profiles

[EN]This Ph.D. thesis presents a general, robust methodology that may cover any type of 2D acoustic optimization problem. A procedure involving the coupling of Boundary Elements (BE) and Evolutionary Algorithms is proposed for systematic geometric modifications of road barriers that lead to designs with ever-increasing screening performance. Numerical simulations involving single- and multi-objective optimizations of noise barriers of varied nature are included in this document. results disclosed justify the implementation of this methodology by leading to optimal solutions of previously defined topologies that, in general, greatly outperform the acoustic efficiency of classical, widely used barrier designs normally erected near roads.
