1997年8月28日，在Ronco s村境内的Riale Buffaga急流中发生的泥石流。阿斯科纳（蒂奇诺，瑞士），已经模拟了一个良好的可靠性程度，由于存在的洪水事件之前的洪流通道的形态调查和存在的雨量计，记录降雨事件的分辨率为10分钟。有了这些数据，就有可能对森林火灾对特定集水区水文地质反应的影响进行定量分析。在目前的情况下，10年一遇的降雨事件导致了100至200年一遇的洪水事件。这一结果清楚地量化了森林火灾对领土安全的可能后果。版权所有© 2003年约翰威利父子有限公司。
The debris flow of 28 August 1997 which occurred in the Riale Buffaga, a torrent channel in the territory of the village of Ronco s./Ascona (Ticino, Switzerland), has been simulated with a good degree of reliability due to the existence of morphologic surveys of the torrent channel preceding the flood event and the presence of a rain gauge that registered the rainfall event at a resolution of 10 minutes. With these data it is possible to conduct a quantitative analysis of the effect of a forest fire on the hydrogeological response of a given catchment. In the case at hand, a 10‐year rainfall event caused a 100‐ to 200‐year flood event. This result clearly quantifies the possible consequences of a forest fire in terms of territorial safety.
