Importance of DTM accuracy, precision and acquisition technique for estimating ...
Cambra, S.; Pereira, L.; Keizer, J.Wildfires are a frequent phenomenon in Portugal, affecting over 300.000 ha in dry years like 2003 and 2005. Directly and/or indirectly, wildfires can strongly enhance the hydrological response and associated sediment losses and, thereby, negatively affect land-use sustainability as well as ecosystem functioning of downstream aquatic habitats. Therefore, the EROSFIRE projects aim at developing a GIS-tool for pre...
Effect of the Resolution and Accuracy of DTM produced with Aerial Photogrammetr...
Cambra, S.; Gomes Pereira, L.; Keizer, J.Wildfires are a common phenomenon in Portugal, affecting on average 100.000 ha of rural areas per year and up to 400.000 ha in dramatic years like 2003 and 2005. Wildfires can strongly enhance the hydrological response and associated sediment losses in recently burnt forest catchments and, thereby, negatively affect land-use sustain- ability of the affected terrains as well as ecosystem functioning of downstrea...
The study of soil, hydrological, erosion and vegetation processes following wil...
Keizer, J.; Nunes, J.; Sande Silva, J.; Gomes Pereira, L.; Vieira, D.; Varela, M.; Prats, S.; Pinheiro, J.; Pereira, V.; Mendes, H.; Malvar, M.The EROSFIRE-II project (PTDC/AGR-CFL/70968/2006) has as overall aim to predict soil erosion risk in recently burnt forest areas, including following common post-fire forest management practices. Although the project’s main focus is on onsite erosion processes, also the export of sediments out of small catchments is addressed. To this end, a study area of about 60 ha located near to the village of Colmeal (...
