Abstract

The limited amount of detailed internal structure of lacustrine (lake) deltas from morphology and widely spaced drill holes has led to the development of simplistic depositional models. To properly understand the geomorphology and internal sedimentology of deltas, it is necessary to determine subsurface sediment facies and their structure. To analyze deltas, other seismic geophysical methods have been hampered by cost, portability and technical limitations (Le. low resolution) and, therefore, has had only limited success. Recent GPR technology has lowered purchase price, maintenance, operating cost, while improved portability, durability and resolution. Published research on the use of GPR in studying subsurface sedimentology and geomorphology is very limited (Ulriksen, 1982; Forgotson et al.1990; Moorman 1990; Moorman et al. 1991; 101 & Smith in press). Our objective is to show and discuss how GPR can be used to better understand subsurface sedimentary structures of different deltas which allows one to improve the construction of depositional models.
