To study the impact of River Nestos (North Greece) dams construction on coastal morphology.

In order to study the evolution of the coastal morphology in the area, an “one‐line shoreline change model” was developed (PELNCON). The model's input comprises the field characteristics, the wave characteristics at the breaker line and a “source” term for the sediment supply rate by River Nestos. The model calculates the shoreline change over a given period of time. The annually transported sediment quantity by the river is estimated using filed measurements and other models' results for various sites along the Greek part of the hydrologic basin of Nestos (Nestos is a transboundary river extending along Greece and Bulgaria).

The “PELNCON” results demonstrate a serious erosion threat for the coastal area due to the sediment budget deficit of about 1.8 × 10⁶m³/year.

The developed model is subject to common structural weaknesses of computational modelling based on the one‐line shoreline change theory.

The developed model is user‐friendly and can be applied to any coastal area of known characteristics, providing realistic results.

This paper is an attempt to model the correlation between two large‐scale phenomena, namely coastal erosion and water/sediment management in river basins, setting at the same time the basis for further study on this particular scientific field.

The purpose of this paper is to examine different quality schemes and to determine how these could be combined by Agricultural Cooperatives into a brand development strategy designed not only to differentiate their products but also to enhance them with higher value added in the competitive landscape of the food industry.

This paper will first address how brands have enclosed quality signs and even more, how consumers respond to it. Then, it will examine to what extent Greek Agricultural Cooperatives have developed brands for their products and whether they have used quality systems in their activities. Thus, the starting point in the paper's argument is that Agricultural Cooperatives have been slow to develop brands while consumers have been displaying a positive attitude towards these products.

This work suggests a solution to overcome the difficulties and drawbacks associated with the notion “cooperative product” and to compare its similarities with a collective brand, which has been previously proposed as a brand development strategy for the Agricultural Cooperatives.

The development of a Quality System especially designed for agricultural cooperatives’ products and, in combination with product certification, can be used as a part of their brand strategy.

Agricultural cooperatives could build a brand development strategy based on quality systems, Total Quality Management elements and hence attain the benefits associated with their implementation.
