15. Determination of net sediment transport patterns in Lirquén Harbor, Chile, through grain-size trend analysis: a test of methods
During June 1997, bottom sediment samples were collected at 76 stations on a rectangular grid in a small port (Lirquén Harbor, south-central Chile) facing siltation problems. The spatial changes in grain-size parameters, analyzed by using three different methodologies to infer net sediment transport paths, are compared with the measured water circulation of

16. USE OF INFORMATION SYSTEMS GEOGRAPHICAL SYSTEMS IN OPERATION SUPPLY / USO DE SISTEMAS DE INFORMAÇÕES GEOGRÁFICAS NA OPERAÇÃO DE SISTEMAS DISTRIBUIÇÃO DE ÁGUA
Water companies have the duty to provide water to the growing demand, which requires a larger quantity of active connections and, consequently, results in an increase of net extension and a larger volume of produced water. This paper aims at presenting a tool for the support of management of water distribution nets in a pilot area in the city of Goiânia GO.

21. Atributos do solo, ambientes e perdas de solo para Ãreas florestadas no sul e leste do Brasil / Soil properties, condition and soil losses for south and east Brazilian forest areas
Eucalyptus cultivation has increased in all Brazilian regions. In order to recommend good management practices it is necessary to understand differences in soil properties where eucalyptus is planted. In addition, aggregate stability analyses have proved to be a useful tool to measure soil effects caused by changes in management practices. Besides, the evalu
