Purpose Focussing on the event “Tlemcen Capital of Islamic Culture 2011”, the purpose of this paper is to examine the changing perception of the city’s image, assess its durability and determine its relationship with the development of sustainable cultural tourism. Design/methodology/approach This research is tested by an empirical study that combines a qualitative and a quantitative approach. The qualitative study is based on semi-directive interviews, whereas quantitative study is based on statistics from the Wilaya Tourism Department. Findings The results of this study indicate first of all that the perception of the city’s image by the inhabitants is not static and that it follows the same process of evolution of the perception of the image by tourists but in relation to other factors such as awareness and age. The second result shows that the sustainability of the image must be verified both inside and outside to achieve sustainable cultural tourism. Originality/value This study is in line with previous research with another point of view on the city’s image and another case study which is the historical city of Tlemcen. It serves to examine the evolution of the perception of the city’s image produced by the event and to assess its sustainability.

The dam of Hammam Boughrara is an embankment dam built in a transboundary basin, between Algeria and Morocco; it was type-approved and delivered in 1998. This dam was supposed to solve the lack of drinking water in Oran (Algeria's second largest city) and enhance the agricultural perimeter of the area. It should regulate an annual water volume of 59 million m3. However, the northwest Algeria has experienced a fairly severe drought since the 80s. This article aims to show the impact of this drought on the amount of surface water that can be mobilized by this dam. The rainfall series recorded at four stations, located within the basin of the dam, were examined using the proportional deviation from the average, the running average, the frequency analysis, the Pita’s index and the standardized precipitation index. These methods have shown a significant decrease of rain, starting from the hydrological year 1975/1976. These same approaches were also used to analyse series of flows spread over a longer period. This fact revealed three periods of drought which are 1940–1945, 1955–1967 and the most recent one highlighted by the rainfall series, starts at the year 1975/1976. The regularized water volume of the dam, calculated from the series of flow rates, is around 37 million m3. This value reflects a deficit of 40% of the regularized volume predicted by the designers of the dam.
