Reyes-Merlo, M.Á., Díez-Minguito, M., Ortega-Sánchez, M., Baquerizo A. and Losada, M.Á., 2013. On the relative influence of climate forcing agents on the saline intrusion in a well-mixed estuary: Medium-term Monte Carlo. In: Conley, D.C., Masselink, G., Russell, P.E. and O'Hare, T.J. (eds.), Proceedings 12 International Coastal Symposium (Plymouth, England), Journal of Coastal Research, Special Issue No. 65, pp. 1200–1205, ISSN 0749-0208.--> In this work we analyze the estuarine circulation and the dependence of the salt intrusion on the climate forcing agents in the Guadalquivir river estuary. The salt flux driving mechanisms are discussed. Exchange flow is identified and characterized by means of estimates of the effective vertical turbulent viscosity Nz, which decreases from 1.2·10−3 m2/s near the mouth to 3.3 · 10−4 m2/s in the middle reach of the estuary due to the decrease of the shear stress and to the longitudinal density gradient. Power-law relationships are obtained to assess the relati...
Engineering infrastructures require regular maintenance and/or repair activities that have important social, environmental, and economic impacts. Despite their growing importance, few studies have focused on fully integrated analyses. This work presents a general methodological approach to design databases of engineering maintenance activities for their assessment. This methodology was applied to the case of dredging projects in the ports managed by the Andalusian Regional Government (Spain). The resulting database contains 87 fields of information obtained from the analysis of 70 activities performed between 1993 and 2015. This database is free, public, and available to the scientific community, and it was implemented in PostgreSQL using the PostGIS extension for spatial data; therefore, it can be integrated in a GIS. The assessment of deviations from the initial projects and the comparison between locations enhanced our methodology, which represents a valuable tool not only for scientists and managers to improve the decision-making process when planning future strategies, but also to evaluate the environmental impacts.
