Hello, my name is Rodrigo, I'm from Brasilia Brazil. As an example of stock we have water retention. So I'm going to talk about Lake Paranoá. An artificial lake located in Brasilia, capital of Brazil. It was conceived in 1894 by the Cruls Mission [1] and made concrete with the construction of the city, under President Juscelino Kubitschek. The lake is formed by the dammed waters of the Paranoá River. It has 48 square kilometers of area, and about eighty kilometers of perimeter, with some artificial beaches, such as "Prainha" and "Piscinão do Lago Norte". The presence of the lake is then justified as an aesthetic and leisure factor. Its construction was designed to increase air humidity, decrease local temperature and establish a source of leisure for Brasilians. As an example of flow, we have the wholesale logistics in DF, through the flow of food and consumption materials, which through its highways circulate hundreds of trucks daily transporting not only food for local production, but as they said at the time of planning from the region the central west region of Brazil would become the great granary of Brazil.
