Determination of Horizontal Displacement of the Hydropower Plant Mostar in Bosnia and Herzegovina

Hydropower plants are objects which horizontal and vertical displacement must be monitored regularly. Method used for determination of horizontal displacements of the Hydropower plant Mostar in Bosnia and Herzegovina, and its practical execution are presented. Algorithms for regular adjustment of indirect measurements and S-transformations into optimal datum are also presented in this paper. Further, regular adjustments of indirect measurements of the reference and control point coordinates in the conventional datum are performed for two epochs of measurements (December 2014 and June 2015). For each epoch regular adjustments are performed in a way that two base points are fixed, and all the other points, reference and control, are adjusted simultaneously. For adjusted values, in both cases, the S- transformation algorithm is used for transformation from conventional to optimal datum. Horizontal displacements are calculated between those two epochs, as well as regarding zero-epoch (year 1988). The analysis of the obtained position displacements is given, as well as the recommendations for the future series of measurements.
