You can't determine the actual water depth but the relative one. The relative relationship between each facies can be detected by grain size, micrite content and some other sedimentary fabrics. 

Dear colleague:

There is a wide range of marks and traces in the field of inorganic and organic sedimentology which have some implications on the paleobathymetry of sedimentary strata. The same holds true for the floral and faunal remains in paleontology. There are much more publications, items and species of assistance to address this issue than room available in this Q&A process on Researchgate.

I wish you much success

Following the procedures prescribed in Standard Microfacies types and Facies belts (Fluegel) will give an estimate on carbonates. For clastics, mixed clastics other indicators such as sedimentary structures, fauna/flora content may be of help. Either case, you can get relative depth ranges, not absolute values. As Prof.H.G.Dill has rightly pointed out, a plethora of literature is available in this context, that could not be contained within this section. 

Thanks all dear for suggestions.

Dear Dr. Islam

You either want to know about the water table (hydrology) or about the depositional environments of different rock facies? I am unclear. Would you like it clear?

Ijaj thanks many for your answer but actually I want to know water depth from sedimentary facies sequence of clastic rocks. I know that ichnofacies, carbonate facies, fossil content are important but I studied the fluvial sedimentary sequence without fossils or carbonate.

Dear Prof. Harald G. Dill,

Thanks many for reply. Actually I want to know the relative water paleodepth from sedimentary facies sequence of clastic rocks. I know that ichnofacies, carbonate facies, fossil content are important but I studied the fluvial sedimentary sequence without fossils or carbonate. I am looking for best few publications regarding paleodepth from clastic rocks. I am sorry to give you trouble.

I wish you much success

Did you think about using sedimentary structures such as ripple marks, mudcracks, cross-bedding? How about reactivation surfaces in floodplain deposits? On a large-scale, bedforms representing low or high flow regime may provide clues to the depth of water.

Thank you Nazrul I. Khandaker for your comments. Exactly I tried in this way using sed. structures. There is a old method to use sequence thickness but I am thinking about any new techniques using thickness of sequence.

The thickness of planar cross-bed  lithofacies or barform packages can be used to estimate average channel depth, according to Allen, 1984; Bridge and Tye, 2000

Thank you Rupa for your reply. I shall try for these paper.

There is an absolute plethora of information on interpretation of clastic sediments. A start would be the book "Facies Models" edited by Noel James and Robert Dalyrmple. http://www.cspg.org/cspg/CSPGIMIS20/Publications/Bookstore/Publications/Facies4.aspx  You won't go wrong if you can only find earlier editions (1-3) of this book.

Ichnology (trace fossils) is/are key in interpreting sedimentary sequences and relative water depth. Start with this volume by Pemberton et all: https://www.gac.ca/publications/view_pub.php?id=37

Finally you need to understand and use the regional context of your Tertiary sequence. Sounds like you would know your rocks are sitting in a giant mega-delta so I would pay attention to deltaic sediments as described in the above books and also papers that the books mention.

And I would also talk or correspond with any sedimentologists or ichnologists that you know on the specifics of your project as you proceed on it.

Thank you Prof. Jim Barclay for your valuable comments. Regards.

Really. I also think that besides the Ichnofossils we can use a number of absolute methods help to solve the problem.
