.... At the end of December, two days of torrential rain transformed the streams descending from the mountains to the sea through the city of Funchal into raging torrents of muddy water. The rushing water rolled large boulders noisily along stream beds, demonstrating vividly to Lyell how the streams had carved...

... Trough-mouth fans (TMFs) are large depocentres of glacially influenced sediments formed at the mouths of some glacially carved cross-shelf troughs ( Vorren et al. 1989 ). They develop in front of ice streams grounded at, or near to, the shelf edge, which transported large volumes of glacigenic...
