Abstract

The main of the research is to study the efficiency of generalized compensatory techniques (CT) combined detention and biorretention to control diffuse pollution from urban drainage. The main hypotheses of the research justifies new experiments with CTs to control diffuse urban drainage, since the efficiency is evaluated with generalized adaptation strategies under long term quali-quantitative aspects in an eco-hydrological basis. The steps of the research include: 1) discussion of the scope and limitations of methodologies, criteria to design and to evaluate efficiency of TCs controlling quantity and quality in urban drainage systems, 2) evaluation of the applicability of indicators with an eco-hydrological basis in the generalized assessment , the quantity and quality of the water, the efficiency of TCs; 3) experimental study of CT in minor drainage , to evaluate the effects of combined detention-biorretention devices, including conception, design, installation, monitoring, modeling and analysis of efficiency during the lifetime of the TCs, and 4) simulation of long-term adaptation scenarios to compare the effect of combined detention-biorretention devices in TCs in macro-drainage systems of selected watersheds. The experimental approach includes modular dimensioning of detention devices to control runoff (Vmax quantity; eff ”Qquanti) and pollutant loads (Vmax, quality; eff”Y, quality) and biorretention (Vmax, bio; eff”X, bio). The adaptive approach studies how the CTs can be adapted during the lifetime of the devices through two future modifications: (1) the demands of urban drainage (”Qquanti (t), ”Yquali (t) and ”Xbio (t)), and (2) Vmax system capacity, TC (t) as the integration efficiencies of control eff”Q, quantity (t), eff”Y, quality (t) and eff”X, bio (t). The methodology will be applied to new developing areas on Campus II of EESC/USP. The timeline of the research includes an abroad doctoral internship. This proposal is linked to three projects: (1) MAPLU2 - Stormwater Management in Urban Environment / FINEP, (2) FAPESP Thematic Project "Assessment of Impacts and Vulnerability to Climate Change in Brazil and Strategies for Adaptation Options", and (3) Casadinho / PROCAD (UFAL-EESC/USP) "Monitoring advanced biotechnological processes and environmental quality".
