Assess the availabilityand quality of water inthe Riacho Fundo sub-basin using theintegration of SWAT andWEAP models tosupport the decisionmaking, planning andmanagement of waterresources in the FederalDistrict.
General objective
Objectives .
To evaluate the use of WEAP as a decisionsupport system to water resourcesmanagement in the DF
Specific Objectives
To integrate SWAT and WEAP models for thesimulation of water quantity and qualityscenarios in the Riacho Fundo watershed.
To model hydrological processes and nutrientloads in watersheds with predominant use ofurban land using the SWAT model.

The integration of SWAT and WEAP provides good results in the caseof simulation of water quality. Since the WEAP can not simulate diffusepollution, SWAT is a very useful model that provides this kind of resultsin a detailed way, and it consider all the features of the basin as landuse, management, soil type, among others.

Integration of models depends on the level of detail of thestudy
The integration SWAT-WEAP needs a defined approach toestablish a link between changes in land use in SWAT andthe rate of population growth in the demand nodes in WEAP
Programa de Pós-Graduação em Tecnologia Ambiental
e Recursos Hídricos
SWAT provides very detailedsimulations of hydrology and quality
The WWTP node (WEAP) showed the highest concentrations especiallyfor the Nitrogen, but the contribution of the tributaries helped on thereduction of the concentrations along the Riacho Fundo River.
The presence of phosphorus was mainly affected by the sediment loadsfrom the watershed. The final concentration at the outlet of the basinapproached the regulated limit defined by the CONAMA Resolution357/05, showing the vulnerability of the lake.
The NT and PT values in sub-basin outlet classified the water source asmeso-eutrophic, representing intermediate levels of productivity

The scenario without release of treated sewage from the WWTPRiacho Fundo, showed good results in improving the quality of the river
The scenario increasing the NT removal efficiency of the WWTP RiachoFundo reported significant improvement in the water quality of the River Riacho Fundo
