TRANSCRIPT
The DPSIR framework in analyzing and addressing floodThe case of Belém / Pará / Brazil.

The DPSIR model was created by European Environmental Agency (EEA)

Population growth
• 1.400.000,00 Source: (IBGE/IDESP, 2012).
The pressures are direct causes
The first track 1 should not have habitation, the second can with average risk and third is permitted for habitation.
Pressures
StateThe pressure cause a state
• Flood area: problems for rivers runoff, topography, water level, tidal regime the presence of houses along the rivers make difficult the flow of the river
Impact – generate lossesVulnerability:
Leaving the city vulnerable to floodingIn figure have several points of flooding.

Policy Maker
For the reason, it is necessary to Analise the factors through the DPSIRModels and obtain an answer to this impact, considering the environmental quality.
Response
• Then, the response to the flood problem should be ➢ Flood control measures; ➢ Structural measures; ➢ Non-structural measures; ➢ Economic evaluation measures for flood.
• The results indicated that the main indicators are:
Force: geography and geomorphologia locatian, urban expasian.
These elements generate as pressure and state flooding and material and human losses.
The better response are engineering woks and preparation of a Master Plan.
The model concluded that Belém has high vulnerability and risk of flooding.
CONCLUSIONS
