APPLICATION OF RAPID ASSESSMENT PROTOCOLS (RPB) AND URBAN RIVER ASSESSMENT PROTOCOLS (RUAP) IN THE MIDDLE SEGMENT OF THE IGARAPÉ DO MINDU, MANAUS (AM)

Abstract

Rapid Assessment Protocols (RAP) are scientific tools that enable efficient evaluation of the environmental quality of water bodies. The Urban Rivers Assessment Protocol (URAP) is an extension of RAP, specifically adapted for urban environments, considering specific factors such as urban location, land use, presence of buildings, channel modifications, and water quality. These protocols were applied to the middle sector of the Mindu basin, which is part of the São Raimundo Urban Watershed in Manaus, AM. The study was organized into five distinct stages: literature review, acquisition of cartographic data from official and open-access digital sources; supervised fieldwork at three points of the Mindu stream; data tabulation, and the creation of cartographic products using Geographic Information Systems for discussion and interpretation of results. The results indicated that the channel is in good condition, with moderate impact levels due to human activities. In terms of conservation, only the Mindu Park and the Mindu Ecological Walk had a preserved channel, owing to their status as Permanent Preservation Areas and continuous public service actions. Census data revealed that the residents of the Shangrilá Complex, Mindu Park, and Mindu Ecological Walk lack adequate facilities for storing household waste. Additionally, the water drawn from wells in private households is compromised due to the type of sewage system still in use (rudimentary cesspools) and the presence of garbage in the upstream watercourses of the Mindu Municipal Park.
