Resumo: | Conservation of continental waters is becoming increasingly necessary due to the growing negative environmental impacts and the acceleration of its scarcity. In the Center of Research and Management of Continental Fishing Resources (CEPTA/IBAMA), city of Pirassununga, SP, Brazil, located in the “Velha” dam. The lifespan of this dam was determined by sedimentation rate, comparing two different methodologies. One was the bathymetry with a hydrometric and other hydrometric using sedimentation chambers. The samples collections in these last ones had occurred in the water column the 50 cm above the sediment, in the dry and rainy periods, during twelve months. With this methodology can be calculated the sediment rate of 7.0 mg.cm-2day-1 and 0.66 mg.cm-3 annual density. The calculation of lifetime for the “Velha” dam was 7.5 years. Through the bathymetry was determined the loss of depth along the entire length of this dam, with an average, of 0.07 m.year-1. It was concluded it will take 72 years for this dam to be completely silted up, this time can be reduced if no mitigating actions for the current impacts and planning to avoid others who may possibly occur. |

No Centro de Pesquisa e Gestão de Recursos Pesqueiros Continentais (CEPTA/IBAMA), no Município de Pirassununga, SP, localiza-se a represa Velha. O tempo de vida útil desta represa foi determinado por meio da taxa de sedimentação, comparando-se duas metodologias distintas. Uma delas consistiu na batimetria com guincho hidrométrico e a outra utilizando câmaras de sedimentação. As coletas das amostras nestas últimas ocorreram na coluna de água a 50 cm acima do sedimento, nos períodos de seca e chuvoso, durante doze meses. Com esta metodologia pode-se calcular a taxa de sedimento de 7,0 mg.cm-2dia-1 e a densidade anual de 0,66 mg.cm-3. O cálculo do tempo de vida útil para a represa Velha foi de 7,5 anos. Por meio da batimetria foi determinada a perda da profundidade ao longo de toda a extensão desta represa, sendo em média, de 0,07 m.ano-1. Concluiu-se que serão necessários 72 anos para que esta represa possa ser totalmente assoreada, este tempo podendo ser reduzido se não houver ações mitigadoras dos impactos atuais e planejamento para evitar outros que possivelmente poderão ocorrer.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Universidade Estadual Paulista, Centro de Estudos AmbientaisUniversidade Estadual Paulista, Instituto de Geociências e Ciências ExatasUniversidade Estadual Paulista, Centro de Estudos AmbientaisUniversidade Estadual Paulista, Instituto de Geociências e Ciências ExatasFAPESP: 00/05364-0Instituto BiológicoUniversidade Estadual Paulista (Unesp)Bufon, A.g.m.
