Análise territorial à luz da sensibilidade às águas: o caso de Acanhã, Sandra Cavalcante.

Abstract

Campina Grande is a Brazilian Northeast semiarid city, located at the "Draught Polygon" and it is an example of a city among many others that were created and prospered from water resources. However, as far as the city grew, the rivers and lakes lost their importance beyond a simple supply and were forgotten by the population and overlooked by authorities who manage the city. The soil sealing increased as consequence of the development event. It is now generating big disorders to the citizens, mainly at the rainy season. That is the case of Acanhã region, located at Sandra Cavalcante´s neighborhood, study object of this paper. Therefore, the objective is to analyze the current legal urban planning instruments efficiency and implementation using different scenarios to diagnoses the current (real) region situation and compare it to the scenario provided by law, in terms of imperviousness and urban waters interaction, aiming to reconnect the population to water resources, selecting and using water sensitive urban design principles, low impact development measures and Sustainable Urban Drainage System. The study was developed collecting field data and execution computer simulations using the software Storm Water Management Model and seek to propose recommendations and considerations to improve the real scenario. It should be emphasized that the present study does not seek alternatives to solve all the urban discomforts generated by conflicts with water resources, but it is important to draw attention from the agents of urban design change to the current state of microdrainage of the area and to prevent it from reaching an even more critical scenario so that there are no changes that are occurring, since the results The simulations are not satisfactory in relation to the accumulation of surface runoff in the blocks.
