Example To find difference in elevations between two points P and g situated on the opposite banks of river, reciprocal levelling was done and the following readings were noted. Instrument Staff reading Station P Remarks P 1.824 distance between P and Q = 1010 m 9 0.928 R.L. of P= 120.25 m Find R.L. of Q. Also find the combined correction for curvature, refraction and collimation adjustment. 2.748 1.606
