To establish maximum and minimum design groundwater table
To establish maximum and minimum design groundwater table
(OP)
Hello,
In a project I have groundwater monitoring (standpipe piezometers) data for 4 months, along with geotechnical recommendations the client requirement is "to establish maximum and minimum design groundwater table with a 1% probability of exceedance in any given year (ie. 1 in 100 year return period)".
Could anyone help on this.

Another question is, are there any creeks/rivers nearby? If so, then is your site hydrologically connected to the river?
We exclude this kind of language from our scopes when requested. All you can really do is provide a reasonable design groundwater elevation.

the location in Oman.
Hi Mike,
the groundwater level is about 8m below ground level, the underlying strata is Gravel/ Conglomerate to 6m depth, followed by Shale/ Mudstone to 30m. Groundwater recorded on daily basis, there is fluctuation due to recent rains and now average depth is about 7m. The site is located in a shallow river/ wadi (not active, only surface runoff after the rain) basin.
Does this require a detail analysis or any simple calculations.

The question is what is the historical information on groundwater in the area? You can't predict 100 years + of groundwater behavior from 4 months of data. A very experienced groundwater hydrologist with lots of experience in the area might be able to make a guess.
