Coastal protection of urban fronts against global warming (PROTOCOL)

One of the main challenges ahead for world’s society is the management of climate change and the subsequent sea level rise (SLR). The coastline gathers one of the most intensely exploited areas settled by humans: half the world’s population lives within 60 km from the shoreline. The effects caused by SLR will affect millions of people, as well as infrastructures, industries, farming settlements, tourist resorts and urban developments.

This project aims to provide recommendations to minimize the impact of the sea level rise on coastal urban fronts. Three case studies have been selected in Spain, Mexico and Portugal.

Integrated verification of the hydrodynamical and structural behavior of a breakwater and its implications on the investment project (VIVALDI)

This project takes an ambitious step forward in the current State of the Art and technological  development, by means of a new methodology for assessing the joint probability of failure of  the main modes of failure attached to the ultimate and serviceability limit states in any type of  breakwater.

The  methodology  accounts  for  the  simultaneity  and  compatibility  of  agents  and  actions, and their impact in the attainment and principal failure modes as well as their mutual  dependence,  their  space-time  evolution  considering  different  time  scales  of  the  external  agents  and  their  actions  during  the  construction,  service  life,  maintenance,  repair  and  dismantlement.  The  conceptual  part  of  the  project  will  be  developed  under  a  combination  of  experimental and numerical frameworks, once the principal failure modes have been mapped and their possible evolving connections have been drawn as failure trees. The conceptual model will consider as starting hypothesis the recent works of the research team.

Morphodynamics of heterogeneous beaches in the Andalusian littoral of the Alborán Sea (MORPHAL)

This project studied, described, characterized and modeled the morphodynamics of the heterogeneous beaches located in the andalusian littoral of the Alborán sea. In the analysis we included the different forcing agents (waves, wind and sea levels), their simulation with different temporal scales and their propagation to the coast (surf zone), the interaction between the hydrodynamics and the heterogeneous beaches, including both the effect of the waves and the swash processes in the beach front, and their effects on the sediment transport, and the evolution of the beach profile reproducing the formation of bars, steps and berms and their evolution depending on the forcing and the different temporal scales (forcing-response).

Integral method to diagnose and forecast the consequences of human actions in the Guadalquivir estuary

With a view to recovering the ecosystem-services, and balancing the socio-economic and environmental demands of regional stakeholders, an exhaustive research programme was initiated in the summer of 2007 in the Guadalquivir River Estuary. This study, carried out in close collaboration with the Institute of Marine Sciences of Andalucia, included detailed field studies combined with hierarchical monitoring and modelling of many aspects of the Guadalquivir estuary ecosystem (namely, morphology, sedimentology, hydrology, hydrodynamics, biogeochemistry and biodiversity). High resolution measurements were needed to resolve the spatial and temporal scales of variability in this extremely dynamic estuarine system. This study demonstrated that the application of robust and cost efficient technology to estuarine monitoring can quickly generate the scientific foundations necessary to meet societal and legal demands, and can provide a suitable tool to quickly assess the cost-effectiveness of remedial solutions in the environment.

Biogeochemical flows dynamics in the Bay of Cádiz. Field measurements and numerical modeling

Bays are widespread coastal features and unique natural environments that are becoming more important in modern society due to their strategic locations and ecological relevance. The Cádiz Bay (SW Spain) provides an interesting example of a heavily altered bay, with historical records indicating that the first human settlements took place over 3.000 years ago. Recently, the Bay has experienced dramatically rapid and relevant changes as a result of human activities: a new bridge was completed in 2015 and a new container terminal has been under construction at the Port of Cádiz since 2012.

Thus, different field surveys have been carried out before, during and after the construction to assess the dynamic of the bay and which effects are caused by the future interventions. To increase the understanding of the dynamic of the bay, two different numerical models have been implemented to predict the hydrodynamic and morphodynamic behavior.

Unified design method for design and verification of breakwaters (UNIDIA)

A unified design method for the calculation of the wave-breakwater (energy balance) interaction behavior considering the main breakwater typologies was developed within this project. Based on data obtained from experimental and numerical tests, the values ​​of the reflection (modulus and phase), transmission and dissipation coefficients of the wave were obtained. It is remarkable the progress achieved in the description of the variation of the reflection, transmission and dissipation coefficients through the sigmoid function, since it was proven that this function allows the definition of the behavior of the main types of breakwaters.

A support software was developed in order to evaluate the behavior of breakwaters. This tool allows engineers to design a breakwater in a simple and fast way according to the requirements of the project.

Improvements on the stability of breakwaters over cohesive soils (AREDIS)

The main objective of this project was to develop techniques in order to deal with breakwater design over soft soils. Physical model tests were carried out, allowing the analysis of the interaction between waves, breakwater and soil, with special attention to the processes of liquefaction. Practical solutions to the current problems of designing breakwaters on muddy or cohesive soils were studied, proposing concrete solutions focused on the foundation and the settlement of the structures. A series of recommendations were proposed for their use in applied engineering.

Reliability of port structures

This project was based on an exhaustive physical testing plan, measuring pressures, water levels, discharges and image and video. Additionally, an in-situ measurements campaign on a real breakwater in Gijón Harbour was carried out.

The main contributions of the project were: (1) proposal of a methodology for quantification of scale effects on physical models; (2) accurate definition of the energy balance in front of a breakwater considering wave-structure interaction; (3) design of a new type of armor unit which allows for a better stability of the mound; (4) development of a management model for the optimization of the construction processes; (5) analysis of failures of port cranes under wind forces.

Technological development of maximum stability rubble mound breakwaters

The main objective of the project was to obtain a new typology of breakwater with maximum stability against waves, in order to optimize the design and construction of ports, allowing them to be located in areas subjected to strong waves, and avoiding damages under extreme and exceptional work conditions. Deriving from the results of this project, a patent about the design of a maximum stability breakwater was developed (ES 2 288 336 A1).

Integral study of the environmental effects of wind farms on earth

The project dealt with the study of the environmental impacts caused by wind farms on earth. The mains results were: (1) analysis of the modification of the wind field due to the presence of an isolated wind turbine or a wind farm; (2) study of the death rate of birds and bats, including the creation of a database with the results; (3) study of the modification of climate, hydrology and local flora; (4) landscape modification, with the development of a software to evaluate visual impacts. The project was concluded with the creation of a series of recommendations which have been transferred to public organisms and companies.

Dredging in the Andalusian port system: management and decision-making methodology (DRAGAPORT)

Most of the Andalusian ports, both in the western and eastern part of the region, are submitted to recurring dredging works. Dredging is a necessity in harbors like Punta Umbría (Huelva), Carboneras (Almería), Chipiona (Cádiz) or Estepona (Málaga) in order to achieve the capability for which they were designed. In other cases, dredging works aim to regenerate beaches.

The main objetive of this Project was to develop an integral management and decisión-making methodology for the planning of dredging works in Andalusian Ports including (1) an exhaustive analysis of the current situation and behavoir; (2) prediction of future scenarios on a short and long term basis and (3) technical and environmental optimization including total cost analysis.
