Abstract

Nonpoint pollution is simultaneously a technical and socioeconomical challenge. Surface water quality is a direct consequence of activities developed within a watershed. The Increasing watershed impermeabilization and extensive usage of industrial chemicals, fertilizers and pesticides, in addition to products and services inherent to economic development are the main factors associated to nonpoint pollution inputs. As it takes place within the hydrological cycle, nonpoint pollution is very diversified regarding sources and pathways. Within that context, nonpoint pollution modelling is an important support tool to source area identification and to the decision-making process, aiming to achieve impact mitigation and implementation of water resource management instruments. The choice of a nonpoint pollution model must consider well defined criteria. This work presents a review of nonpoint pollution models, focusing on the implementation of water resource management instruments to the Brazilian reality. Additionally, it presents the main challenges and current directions of nonpoint monitoring and modelling
