In our information era, the current trend of adoption of new technologies for automation of dam monitoring presents a challenge when it comes to accurately monitor absolute 3D movements of a dam. In many cases, dam movement is measured by means of plumb lines and manual surveying techniques. In the first case, automation can be done by optical or electronic means but, instead of an absolute motion which is only restricted to inverted plumb lines anchored deep under the foundation, we obtain tilt and, from it we can estimate the motion. In the second case, being surveying campaigns, automation is rarely possible and hence, the number of readings over time is scarce.

The research makes use of the storm transposition principles incorporating meteorological and topographical factors. Through a practical case study (Palancia river basin-Spain) the research shows the feasibility of the practical application basically oriented to optimal dimensioning of large dams and other flood control and protection hydraulic infrastructures. Key concepts introduce in the method include the central gradient linked to the depth of maximum precipitable water in the atmosphere, and its variation in different directions around a given geographical point, allowing isolating in practice the influence of the topography in the transposition procedure. The final goal is to derive and quantify the hypot...
