Welcome to the website of the Erosfire project. This website gives a clear overview of the Erosfire project and all fire related studies.

The Erosfire project studies the post-fire effects on soil erosion, started with the aim to develop a software tool, integrated in a GIS-environment, that allows to assess and map, at the scale of individual hillslopes, soil erosion hazard in recently burned forest areas for different scenarios of post-fire land management, including “no-intervention” and considering diverse erosion mitigation and control measures.

This project began in 2005 with a simple methodology based on Rainfall Simulations and Open Plots focused at the slope scale, and then in 2007 the ErosfireII began to test this tool in other burned areason slope to catchment scale.

In this website you can observe some of the techniques applied in the study of soil erosion, since the beginning of the project till the latest’s advances on equipment and methods.

Field instalations

Installation of rainfall gauges and sediment fences, followed by runoff plots (slope-scale and micro-plots) and, more recently, soil moisture sensors.

Flight mission for obtaining high-resolution aerial photography and, based thereupon, a high-resolution DTM. We ourselves do the ground work for this mission, i.e. placing control point on the ground and measuring their coordenates with GPS.
