Urban River Policies: Multilevel Analysis and Community Engagement in Curitiba.

This study investigates urban river policies, emphasizing the gaps in understanding the interactions between riverine communities and governance systems. Using empirical and theoretical methods, the research applies multivariate analysis and Structural Equation Modeling (SEM) to data from a representative sample of 1740 residents of Curitiba. The study maintains a 95% confidence level with a ±2.

Learning from the operation, pathology and maintenance of a bioretention system to optimize urban drainage practices.

LID practices for runoff control are increasingly being used as an integrated solution in urban drainage, helping to achieve hydrological balance close to the pre-urbanized period and decrease the diffuse pollution transported to urban rivers. Regarding bioretention, there is already broad knowledge about the detention of peak flows and their treatment capacity for many pollutants. However, there are still few field studies in microdrainage scale, which analyze the actual operation of these devices and raise common problems found, especially in subtropical climate.
