The Importance of Water in Excavation
When excavating a site, the presence of water can greatly affect the process and results of the excavation. Water is a crucial element in excavation, as it can help preserve artifacts and materials, act as a natural barrier to prevent damage, or make excavation more difficult and time-consuming. In this article, we will explore how the presence of water affects an excavation site.
Water as a Preservative
One of the most important effects of water on an excavation site is its ability to preserve artifacts and materials. For example, if a site is submerged in water such as a shipwreck or a sunken city, the artifacts are kept in near-perfect condition due to the low oxygen levels in water, which prevent the decomposition of organic materials. These underwater sites can be a treasure trove for archaeologists, as they can reveal important information about the past without the typical decomposition process that would occur on land.
Water as a Barrier
Water can also act as a barrier that protects artifacts and materials from outside forces. For example, if a site is located in a marsh or bog, the muck and water can create a natural barrier that protects the site from looters or degradation. Additionally, if a site is situated next to a river or other body of water, the water can prevent soil erosion and help keep the site intact, preserving it for future excavation.
Water as a Challenge
While water can be helpful in preserving sites, it can also create challenges for excavators. For example, if the site is located below the water table, excavators will need to pump out water to keep it dry, which can be time-consuming and expensive. Additionally, if the site is located in a flood-prone area, excavators will need to be aware of the potential for sudden changes in water levels, which can damage the site and artifacts.
Conclusion
The presence of water can greatly affect an excavation site, whether it is helping to preserve artifacts and materials, acting as a protective barrier, or creating challenges for excavators. As such, it is important for archaeologists and excavators to carefully consider the presence of water when planning and executing an excavation site. With careful planning and consideration, water can be a valuable tool for uncovering the secrets of the past.
