I would guess the usual suspect of warfare also played a big role in their eventual decline. Thats usually how civilisations fall...
Its amazing what nature can do after 5 years, so over a 1000 years, unfortunately, takes things beyond recognition. The same problem exists in Cambodia and the mystery of the Khmer civilisation. Angkor was huge, the worlds largest pre-industrial urban centre at its peak. I'm sure that was also built with advanced knowledge. I don't think (mostly) us in the 'west' have given it proper study.
