Abstract: The introduction of novel technical are shown in order to strengthen in the region of Latin America and the Caribbean, the surveillance and monitoring of the negative sedimentation phenomenon in the water superficial reservoirs (natural and artificial).
With the development of a regional project, supported by the International Agency of Atomic Energy (IAEA), Cuba acts as technical director for 15 countries (Argentina, Bolivia, Brazil, Chile, Colombia, CUBA, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Dominican Republic, Uruguay and Venezuela), to foment and to implement the integrated application of 3 nuclear techniques (Fallen Radionuclides Rain (137Cs, 7Be and 210Pb), Compound specific of stable isotopes (fatty acids of the ∂13Cand the Isotopic Hydrology (18O, 2H and 3H)), which are validated as effective tool for the decisions takers in the definition of best strategies and national programs linked to the sustainable the land and the hydric resources. The integrated application of these 3 techniques allows evaluating, in the hydraulic facilities and water superficial reservoirs (natural or artificial), the negative sedimentation impacts in natural and anthropic process as environmental and social risk. Each technique values the whole process and its synergy, contributing results that they expose, from the quantification of the soil redistribution in the landscape, the exact definition of the soil origin that is deposited until the later dynamic characterization of the water body like receiver of that soil that is moved.
