    Abstract One-Line shoreline evolution models have been used as a tool to understand and forecast long-term coastal evolution. However, in some coastal environments, where the influence of the wind is important, the limitations of existing models preclude its direct application to characterize its effect on sediment transport processes. To fill this knowledge gap, we have developed a shoreline evolution model that includes the effect of wind on longshore sediment transport and accounts for beach-dune sedimentary exchange due to aeolian transport. The model produces quantitative estimates of sediment transport and exchanges rates alongshore, easing the assessment of the role of different forcing agents in coastline evolution. The model was applied to the Ebro north hemidelta coast. The results are used to discuss the relative importance of the wind interaction in the evolution of different coastline stretches. Aeolian sand transport at Riumar Beach could cause coastal erosion. At the rectilinear coast, aeolian exchange does not seem to influence the shoreline evolution but the wind-current interaction does. The model provides valuable data when considering the approach to be taken regarding conservation measures. Alongshore aeolian sediment transport can be useful when designing and placing aeolian sediment traps. Conservation of the Ebro north hemidelta coast needs to focus on increasing the river sediment supply. The application herein presented can be regarded as a first step in understanding wave and wind coupling effects in shoreline evolution.

    Abstract In order to quantify the physical forcing processes associated to sediment transport in the inner shelf, sequential moorings were placed in the three access cable routes connecting the Renewable Energy Experimental Zone (offshore S. Pedro Moel — W Portugal) to the shore. ADCP and LISST data were collected to quantify and establish suspended sediment transport patterns in two different seasonal conditions: September and December 2011. ADCP relative acoustic backscatter was calibrated using LISST suspended sediment concentration and grain size, allowing the integration of current, sediment and wave data. In most cases suspended sediment signatures in all three mooring sites respond mainly to locally induced wave resuspension. More complex dynamic interplay was found in the central mooring site where different finer and coarser sediment signatures were identified, most likely associated with the effect of the Lis River runoff and upwelling fluxes.

    Abstract We have prepared a review of the physical-chemical composition and the functional and anti-nutritional properties of quinoa (Chenopodium quinoa Willd.). It is a plant of the Chenopodiaceae family, originally from the Andean regions, adaptable to different types of soils and climatic conditions. Its composition has attracted the attention of scientific community for its high nutritional value, being rich in proteins, lipids, fibers, vitamins, and minerals, with an extraordinary balance of essential amino acids. It is also gluten-free, a characteristic that enables its use by celiac patients. In spite of all these attributes, quinoa is not widely used by consumers due to the high cost of imported grain and little knowledge of its benefits. More studies are required to increase knowledge about this “pseudo-cereal” to demonstrate its functional and nutritional benefits and to study its anti-nutritional effects, since it presents high commercial value and excellent nutritional quality.
