Bottom topography, recent sedimentation and water volume of the Cerro Prieto Dam, NE Mexico

摘要: The Cerro Prieto dam, a relatively small water reservoir in NE Mexico, is one of the main resources potable for Monterrey, city with population about four million inhabitants. A high resolution seismic study using non-linear parametric sub-bottom echo-sounder SES-2000 was carried out this reservoir. High acoustic data interpretation shows that thickness recent sediments due to siltation reaches 3.5-4.0 m. It sedimentation rate (1-2 up 14 cm/ year). Based on data, first bathymetric map and digital model sediment were designed. significant (5-12%) difference between volume capacity value used by National Commission Water (CNA) survey results revealed. Differences CNA indicate storage losses from 12-17 30 cubic meters. obtained through such as one, could be useful improve management.
