The management of urban areas must consider aspects related to urban drainage, especially in hot and humid environments, and such aspects must be incorporated on director plans. This is quite important in urban areas settled on natural fragile hydro-geomorphologic areas. So, the main aim of this paper was to present the urban drainage diagnostic made in Rio Claro (SP-Brazil), discussing its results and evaluating the applied techniques. Further, there were presented some proposed directions based on such analyses. From the obtained results it was possible to verify that the impacts caused by the inefficient urban drainage system incur on direct and indirect effects such as flood, erosion and water quality degradation.

Among Richard Wagner´s work output one finds the Tetralogy The Ring of the Nibelung, composed of four stories interconnected by the same plot. The theme is mythological and involves dramatis personae taken from the nordic universe. This article examines Erda, one of the protagonists of the story as she is called in the musical drama. This article will consist of a series of pertinent questions posed in order to fully understanding of the character and its role in the plot, the vocal type assigned to it and the co-relation between its Leitmotiv and the musical interweaving created by the composer, besides exploring other themes that bear direct relationship with the same.

The purpose of this work is to study the theme “infiltration trenches” in some of its main aspects, in order to subsidize the installation of these structures in the urban area of Rio Claro/SP. For sizing, the “rain-envelope method” was used based on local characterization data and the IDF (intensity-duration-frequency) curve. Five locations were chosen in the urban area of Rio Claro for implementation of these devices, considering the soil type, hydraulic conductivity of each area and minimum lot size according to the Master Plan of Rio Claro. This work also presented an estimated reduction of the runoff in urban lots by using infiltration trenches.
