This is why wet environments are crucially important to archaeologists. However, such sites are not without their difficulties, because land-based prospecting and excavation techniques can often be inefficient, even disastrous, if used in wet environments.

Just like the Neolithic cultivators, prehistorians have had to adapt their techniques to these particular conditions
