1. Evaluation of the lisem model for the simulation of hydrosedimentologic processes in a small rural catchment on the basalt slopes of Rio Grande do Sul, Brazil / Avaliação do modelo LISEM na simulação dos processos hidrossedimentológicos de uma pequena bacia rural localizada nas encostas basálticas do Rio Grande do Sul
The intensive cultivation of the areas of southern Brazil that have poor agricultural potential (shallow soils on steep, basaltic hillsides) has contributed to the degradation of the environment by increasing rates of soil erosion and sediment yields. In this study, traditional monitoring methods have been combined with concurrent mathematical modeling to ve

2. Inverse problems evaluation of dispersive mechanisms / Avaliação de mecanismos dispersivos em rios através de problemas inversos
Nesta dissertação é apresentada a avaliação da dispersão de contaminantes no Rio São Pedro, pequeno curso situado na Bacia Hidrográfica do Rio Macaé, centro-norte do Estado do Rio de Janeiro. Para tanto, utilizou-se uma abordagem que conjugou simulação e observação. A simulação compreendeu a modelagem do transporte de substância conservativa

3. Eutrophication of Cruzeta reservoir in the representative basin of the Seridó river - RN. Natal / Eutrofização do Reservatório Cruzeta na bacia representativa do rio Seridó RN
Eutrophication has been listed as one of the main problems of water pollution on a global level. In the Brazilian semi-arid areas this problem takes even greater proportions due to characteristical water scarcity of the region. It is extremely important to the predictive eutrophication models development and to the reservoirs management in the semi-arid regi

4. Estudo comparativo da aplicaÃÃo de vinhaÃa tratada e in natura em solos sob cultivo de cana-de-aÃÃcar
Brazil is the world leader in sugarcane plantation. Its economical exploration generates residues, standing out the vinasse. Due to the problems of ecological and social order caused by the vinasse, the most plausible solution for its disposition is the application to the soil as fertilizer. However, that application requests studies to guide the management

5. Modelagem e simulação do processo de separação de oleo de soja-hexano por evaporação
Until the two first decades of century XX, the industrial extraction of oleaginosas were carried out exclusively by mechanical process. This process allow to extracted oil of very good quality, but it leads the left residues in the solid material (pie) to be very high, for example 5% for grains as of soy. Such residues besides implying in loss of oil, affect
