The Ro Pirrs watershed has an important hydroelectric potential and for this reason the Costa Rican Institute of Electricity (Instituto Costarricense de Electricidad) since 2001 is building an hydroelectric project, which will generate 128MW. Some authors argue that the application of USLE equation in tropical zones should not be applied because overestimates the results. These evidences promote to test andto fix USLE based tropical soils.
