Integrated runoff-erosion modelling in the Brazilian Water Resources Information System (SNIRH)

摘要

This paper presents details of how part of the Brazilian Water Resources Information System (SNIRH) was developed. The work was carried out by four research networks made up of several Brazilian universities. One of these networks was responsible for the integration of rainfall-runoff models to the SNIRH. In order to integrate the rainfall-runoff models into the SNIRH, the OpenJUMP software was used as an interface to manage the input data and the simulation results. Among the selected models, there is a distributed runoff-erosion model named Kineros with a new friendly interface, in order to provide more detailed simulations exercises, allowing users to analyse the results easily. The model can import the rainfall data from SNIRH and separately simulate the runoff and erosion processes. Finally, this new tool, which integrates different hydrological models in a single base, can support the decision-making process for water resources in Brazil.
