Human errors and climate change cause flooding in Argentina
By: AFP April 4, 2013
According to experts, a key factor in Argentina’s tragedy is the indiscriminate construction of buildings. The tragic floods that hit Buenos Aires and La Plata to 63 km south, far left a toll of 57 dead. Floods in Buenos Aires and La Plata have similar origins cities because they are not taken into account any of the streams that existed in the land where the cities rose. The phenomenon particularly struck La Plata, capital of the province of Buenos Aires, where on Tuesday rained twice the average for the entire month of April, with records of up to 300 millimeters in some areas. Global climate change is characterized by an increase in the intensity and frequency of extreme precipitation is here to stay and must be prepared to face it.

Floods in Buenos Aires and La Plata have similar origins cities because they are not taken into account any of the streams that existed in the land where the cities rose, told AFP the architect Robert Livingston. The graduate also professor at several universities in the region, said that for some architects watercourses are discomfort and often make pipes for its. But rivers do not like running in pipes, as several watercourses under Argentina’s capital.
The Maldonado was a river that had green margins, crossing Buenos Aires as the Thames in London or the Seine in Paris, but many people are unaware that occurs under your feet, said professional. This piping of streams of plain, narrow the possibilities of water runoff during heavy storms, which adds to the waterproofing on the pavement, lack of parks and indiscriminate growth of the construction, he added.
Rainfall between Tuesday and early Wednesday left 49 fatalities in La Plata and a total of 2,500 evacuees, which fell to 1,000 on Thursday, while in Buenos Aires six people were killed and hundreds have fled their homes, and two others died in overcrowded periphery.
The Environmentalist Osvaldo Guerrica Echevarria said the construction of towers in neighborhoods of low houses of Buenos Aires as one of the reasons for this phenomenon. The only solution is to construct and finish, however, not stop. All that does is exacerbate the problem, on the subject, he said that all bases of the towers become impediments to drain the water. There are 20 or 30 meters waterproof down. On the coast of Buenos Aires, there is a barrier of towers, which is an underground dyke to runoff water into the Rio de la Plata.
From the academic side, Matilde Rusticucci, director of the science department of the atmosphere and oceans at the University of Buenos Aires, located to the phenomenon in the context of global climate change with an increase in the intensity and frequency of extreme precipitation. For the director of the department that concentrates the best weather and climate of the country, these phenomena are here to stay and must be prepared to face them. We need to establish an alert system that begins with the part of the weather system that should be guaranteed to reach the population. Structural measures must be taken to adapt to this new urban rainfall extremes and recalled that Buenos Aires had lived a similar situation at the end of last year.
