  We present our study of the 2-D structures of the tidal tails associated with
20 galactic globular clusters, structures obtained by using the wavelet
transform to detect weak structures at large scale and filter the strong
background noise for the low galactic latitude clusters (Leon, Meylan & Combes
2000). We also present N-body simulations of globular clusters, in orbits
around the Galaxy, in order to study quantitatively and geometrically the tidal
effects they encounter (Combes, Leon & Meylan 2000).
