Abstract

This paper presents problems of mass removal caused by excessive rains on National Road 40, San Carlos de Bariloche-El Bolsón section, in the southwest of the province of Río Negro, in Patagonia, Argentina, bordering Guillelmo Lake. The zone in question presents copious precipitations that affect hills, whose slopes have suffered forest fires, that have left them without vegetation and susceptible to erosion.

The aforementioned problems obliged Vialidad Nacional to make an order to the School of Mountain Roads Engineering to solve this problem that is becoming chronic and whose severity increases with each climatic event. In effect, after each rain, large volumes of debris accumulate on the road cutting the route, and cutting off the link between the cities of San Carlos de Bariloche and El Bolsón, generating a great amount of difficulties to the region.

Firstly, measures tending to alleviate this problem in the short term are proposed, and further works in order to achieve a fundamental solution to solve this serious problem definitely.
