Rainfall-related debris flows in Carhuacocha Valley, Cordillera Huayhuash, Peru

Popis výsledku v původním jazyce

Continuous heavy rainfall hit northern Peru in the second half of the 2008/9 summer season. From the end of January to the beginning of March, the Cordillera Huayhuash experienced abnormally high precipitations that exceeded 270 mm. The antecedent rainfall, aggravated with a severe rainstorm of 20 mm on March 7th triggered a large debris flow in the upper Carhuacocha Valley early in the morning on March 8th. The debris flow interrupted drainage from the upper part of the valley damming a lake in the narrow depression between the trough slope and the lateral moraine. As a result of the drainage interruption water percolated through the moraine dam of Cangrajanca Lake where a secondary mass movement occurred in its inner slope. In September 2009, we mapped the debris flow and related landforms and estimated the total area and volume of both mass movements using geodetic measurements. About 104,000 m3 of sediments was moved from the trough slope towards the moraine from which 534,000 m3 f
