Crucecita Alluvial fan's Topography

Topographies used for the study: A modeling methodology to study the tributary-junction alluvial fan connectivity during a debris flow event on NHESS<br>1- A reconstructed pre-event topography based on satellite images and the post-event Lidar topography. This dataset has a 1x1m2 horizontal resolution.<br>2.- Post-event topography lidar scan (acquired in Feb-March 2017 by the Chilean Ministry of Public Works). This dataset has a 1x1m2 horizontal resolution and was post-processed to eliminate vegetation and building.<br>3.- A hypothetical topography that considers a 10x10 m rectangular channel as mitigation works to study different scenarios.<br>
