Piezometric line and phreatic surfaces 1

[zaqqaz]

Hi everybody,

I have a very basic question. Is there any difference between piezometric level and phreatic surface? If so what is it and how they are determined.

Thanks

phreatic surface is groundwater level. Piezometric level can include additional "level" due to water being loaded - or under pressure. Measure by piezometers/standpipes. See:
