Propositivos Urban floods. Risck maps and urban territorial ordination guidelines in the gran La Plata region

Theoretical-methodological and propositional aspects

Abstract

The problem of urban floods in La Plata, Berisso and Ensenada (Gran La Plata) is addressed. The first with a history of flooding by rain, the seconds by sudestadas of the Rio de la Plata. But none prepared for the rainfall flood although these were increasing exponentially in the last decades. The event of April 2, 2013 with extraordinary rainfall of 400 mm and 313 mm in 6 hours, when the ordinary for April is 111 mm., leave 89 deaths. In this context, the theoretical and methodological framework for the management of water risk by urban floods by extraordinary precipitation from the territorial perspective, with exploration of different risk scenarios, is presented and the formulation of guidelines of territorial and urban order that would  collaborate with the process of medium and long term resilience, understanding that they are part of the non-structural measures that should be taken.
