Abstract

By presenting some legal aspects related to disaster management in Brazil, the present work showed that the Brazilian classification of natural disasters is not well established. In the focus on an analysis of the historical views of debris flow disaster management in Brazil, technical-scientific studies about large disaster with debris flows which occurred only in Brazil during the period 1900-2014 were searched mainly through a Web-based survey. The searching result shows that most of bibliographies are proceedings papers and that the papers in scientific journals are only 13% of all the publications. The historical analysis suggests five urgent actions to Brazilian organizations : (i) establishment of correct and uniform terminology about debris flow ; (ii) systematization of hydrometeorological monitoring, its forecasting and topographic survey ; (iii) occurrence registration and database construction ; (iv) debris flow hazard mapping ; and (v) woody-debris flow researches. Based on the Brazilian current situation, the present work proposes comprehensive measures to reduce debris flow disasters, by constructing and using school catchments which are defined as experimental catchments that are used for scientific researches and environmental education for local people.
