Assessed Urban River Hazards: A Case Study of Paragominas, Eastern Amazon

Year: 2026

Type: article

Abstract: Urban rivers suffer from a lack of planning, which results in changes in their morphology and water quality. Due to their susceptibility to hazardous events (HE), it is necessary to find indicators that can assist in analyzing water data. This study identified HE due to land use and occupation in the surroundings of the Uraim River in Paragominas (Pará), Brazil and, we developed a risk matrix. The methodology has an exploratory and descriptive approach. The use and occupation maps showed an increase in the urban network around the Uraim River. The urban water security index is medium, and the Falkenmark Index is adequate. The risk prioritization matrix resulted in the following classifications: very high (3), high (13), medium (4) and low (6). Management tools efficiently identified HE and established proposed solutions for risk situations.
