Publication Ref:
Ehiorobo O. J (2000) “3-D control baseline for deformation studies at Ikpoba Dam” journal of engineering sciences and application Vol 1 (2) pp 68-87 A network consisting of Braced quadrilateral and central figures with some overlapping diagonals was designed at the Ikpoba Dam site. From this network a braced quadrilateral was chosen as horizontal control baselines while the above quadrilateral together with an adjourning one were chosen as vertical control baseline.
