Abstract. The theory of the geomorphological unit hydrograph (GUH) is examined critically and it is shown that the inherent assumption that the operation of the drainage network may be modelled by a corresponding network of linear reservoirs so restricts the instantaneous unit hydrograph (IUH) shape that the effects of further restrictions, reflecting the constraints imposed by the geomorphological laws of the channel network, cannot easily be identified. Without such identification, the geomorphological unit hydrograph theory is untestable and must remain only a plausible hypothesis providing an indication of a two-parameter IUH whose shape and scale factors must still be related empirically to appropriate catchment characteristics.

Study Methodology

Background: Wine tourism is one of the tourism components adopted as part of Portugal’s strategy due to its eminence as a wine producer. Such strategy has received great prominence in recent years and aims to promote regional development from an economic, social, cultural and environmental perspective. The aim of this study was to understand the entrepreneur profile in this sector. Methods: The study uses a qualitative, case study methodology with data analysis and triangulation. In this study, a literature review of scientific studies was carried out on the scientific knowledge in the area of study from a critical perspective and an interview was conducted where qualitative data were collected. Results and Discussion: The entrepreneurs have shown the following characteristics: initiative, innovation capability, optimism, creativity, creative energy, tenacity, selfconfidence, capability for long term involvement with the project, and learning capacity. Conclusion: The study shows that most entrepreneurs state that they have established partnerships with other companies, particularly with restaurants, catering businesses, hotel units, tourism companies and companies that organize tours. This is one of the factors of economic importance recognized by another study which enables increased prominence of the company and widens the value of wine tourism.
