Dam surveillance is vital for the early detection of possible failures or problems so that remedial action can be taken. In the past the multitude of survey results and instrumentation readings involved have been recorded on paper and laboriously plotted manually. Computer systems using database management systems and automatic plotting routines speed up these processes enabling the surveillance engineer to detect more efficiently possible problems. This paper discusses how the use of three-dimensional computer graphics to represent such data provides an enhanced overall impression of the behaviour of structures than is possible by studying tables of data and two-dimensional plots.
