GEOLOGY

Detailed explanation-1: -High groundwater levels can change load-bearing behavior as the second damage type. Main cause is the change or especially the increase in hydrostatic pressure on building components and/or on the entire building.

Detailed explanation-2: -The movement of groundwater in the saturated zone is termed percolation. Water moves slowly by percolation through very small pores along parallel, threadlike paths. 7. Figure 12.9: Water percolates from areas where the water table is high towards areas where it is lowest (towards surface streams or lakes).

Detailed explanation-3: -What will happen to the water level in the stream if the water table is below the level of the stream channel? The stream will lose water to the groundwater system.

Detailed explanation-4: -Springs are formed where the water table naturally meets the land surface, causing groundwater to flow from the surface and eventually into a stream, river, or lake.
