IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Characterization of ephemeral rivers
Author : L. G. Castillo and M.D. Marin
In steep morphology and irregular rainfall regime areas, the floods are presented with high proportion of solid materials transport. Although it is usual that hiperconcentrated flows are presented in semiarid regions, climate change will increase flash floods phenomenon, and will made necessary to control them to minimize their destructive effects. In order to design effective control and intake systems in semiarid areas, it is necessary to know hydrological and hydraulics characteristics of ephemeral rivers. According to the results in Las Angustias Gully (Isla de la Palma-Spain), and based on their similarity to the semiarid watersheds of the Region of Murcia (Spain), the objective of this paper is applying and analysing the methodology, in order to establish a general criteria of calculation in these regions. The first results obtained in hydrology and sediment transport estimation of the Mergajón, Albujón Intermedia and Hoya de España Gullies are presented and compared with the results in Las Angustias Gully.
