Temporary rivers are crucial elements in semi-arid regions such as part of the Mediterranean river basins; since they suppose the majority of the rivers in these areas. The Guadiana Basin, a Mediterranean basin with temporary rivers was the study area chosen for this Thesis. Over the last years, the interest to study temporary rivers has increased notably. This Master Thesis is framed inside a CEDEX (Civil Engineering Research Centre of Spain) Project which objective is to continue developing a methodology for the hydrological characterization of cessation of flow periods in temporary rivers, which focuses on the behaviour of null hydroperiods. This Master Thesis was implemented in the following manner, first, the methodology was applied to a number of rivers from the Guadiana Basin, suitable in terms of being temporary and also due to the fact that they had data series with enough length availability. Secondly, a series of analyses were conducted in order to study possible improvements on the methodology. In light of the results when applying the methodology and the analyses performed, it was concluded that indeed it was possible to enhance and improve the methodology. Thus, the Thesis concludes with the presentation and introduction of the new methodology which is currently being developed.
