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.

Rainwater catchment systems under climate change: an assessment of brazilian and japanese cases
Author : C.O. Galvão1, S. Oishi2, R.L.B. Nóbrega1 and M.S. Dantas1
Rainwater catchment systems are today widely used worldwide for water supply and drainage systems. However, their particular purposes and uses vary according to local and regional characteristics. For instance, in Brazil and Japan, these systems are used, in urban areas, for supplementary source of water for non-potable uses. In rural areas of Brazilian semiarid region, hundreds of thousands of those systems have been built for drinking water supply, in a strategy for drought disaster mitigation. In Japan, researchers are proposing their use for eventual earthquake disaster recovery. This paper describes those cases and their particularities, as well as a simulation of their performance under present and future climate. IPCC's climate models outputs are used as input to hydraulic simulation of the rainwater catchment and storage units. The results show different performances according to the pattern of water usage in each case and also different vulnerabilities.
