The characterization of wave transformation processes in the nearshore is of paramount importance when it comes to assessing storm and flooding impacts, sediment transportation and deposition, harbors safety or design of coastal protective structures. This study analyzes nonlinear wave parameters on Ofir sandy beach. This beach is located along the northwest Portuguese coast which is a highly energetic coast exposed to waves generated far away in the Atlantic Ocean. Despite the existence of rocky outcrops in the nearshore and intertidal zones at the study site, reducing the wave energy that reaches the beach, the study site exhibits pronounced erosive processes. Field observations of six near-bottom pressure records collected at the intertidal zone help to characterize the evolution of wave nonlinearities which are directly associated with sediment transport mechanisms. Data results show that there is an interrelation between the characteristics of the waves and the local morphology. It is also possible to ascertain, more clearly, the level of asymmetry present in the waves propagated at different depths, contributing to a better understanding of the local morpho-hydrodynamics.

Enterprises are facing new challenges. The Information and Communications Technologies (ICT) and Systems that supported their operations are also changing. Enterprises are also becoming more socially responsible. The mobility topic is an actual and unavoidable theme regarding social responsibility, which needs to be developed in a three-bottom line approach throughout social, environmental and economic' dimensions - in order to achieve a sustainable mobility. Necessarily, enterprises need to quickly adapt to the growing and rapid changes in the socio-economic and technological environment, thus embracing Enterprise Information Systems (EIS) - essential components of any enterprise system. Allied to a sustainability interoperability and with the Next Generation EIS (NGEIS) guidance, the future sustainable enterprise mobility can be defined. Other critical topic that Enterprises need to properly address and ensure is the data from their stakeholders to support the definition of strategic decision making and achieve rapid and efficient solutions fully aligned with the market context and their clients' expectation. It is also recognized the importance of the continuous technological evolvement, nevertheless these new technological solutions require private and confidential information of their users. Consequently, enterprises must be concerned with the implementation of adequate technological security mechanisms, that can ensure enterprise data and users' data protection. It is analysed/discussed how its EIS innovative features, together with other systems, could contribute to promote sustainable mobility in enterprises ecosystem and it is also enlightened a Portuguese company case.
