Hi Tilak,

we did some measurements. see DOI:10.1002/esp.2263

The papers I've listed below (some classic; some more modern) include work by some of the key researchers in the fluvial bedload transport field, and will contain valuable datasets using recognised methodologis. You could try Google Scholar etc. using key author and topic searches to find even more references - and the pdf copies of the actual publications. You could expand this list into more specific areas you need information on also (e.g. bedload sand transport; bedload gravel transport; lab/flume data; field datasets; bedload monitoring techniques; modelling).

Each of these papers below have long reference lists of their own, of course, to assist you further.

I hope these papers below help!

Thanks to David and Damian for your prompt respond.

Regarding modern techniques for bed load assessment, You should also look for Colin Rennie (from ottowa) contributes about ADCP for bedload assessment and for the work of US Army on the Mississippi using Multibeam.

There is a good article on Lake Nasser in southern Egypt which may be useful for you. The article is titled " Assessment Lake Nasser Egypt within the climate change" By : El Sayed Ahmed El Gammal, published in Journal of American Science, Vol 6(7), 2010.

If you failed to find a copy of this article, I have a copy and ready to send you if you wish.

Hi Tilak: you may like to look at these Fluvial Geomorphology Reviews published in Progress in physical Geography in which I have identified some recent papers on sediment transport (including bedload):

Stott, T.A. (2010) Review of research in fluvial geomorphology 2006-07, Progress in Physical Geography, 34 (2) 221-245.

Stott, T.A. (2011) Review of research in fluvial geomorphology 2008-09, Progress in Physical Geography 35 (6) December 2011 pp. 811 - 832.

Stott, T.A. (2013) Review of research in fluvial geomorphology 2010-11, Progress in Physical Geography 37 (2), 248 - 258.

Plus these older ones I have published:

Stott, T. A. (1996) Changes in Amount and Size Distribution of Bedload Trap Material During Forestry Operations In Central Scotland. Poster presented at IAHS International Symposium on Erosion and Sediment Yield: Global and Regional Perspectives, 15-19 July 1996, Exeter, U.K. and published in Extended Abstracts Volume.

Stott, T. A. (1997) Forestry Effects on Bed load Yields In Mountain Streams, Journal of Applied Geography 17 (1), 55-78.

Stott, T. A. (2000) ‘Bedload Transport in Rivers: Trapping and Tracing', Geography Review 13 (5), 23-27.

Stott, T. A. (2002) Bed load Transport and Channel Bed Changes in the Proglacial Skeldal River, Northeast Greenland, Arctic, Antarctic and Alpine Research 34 (3), 334-344.

Let me know if that helps.

Good luck,

Hi Tilak,

we did some measurments on the Loire River (France) using isokinetic samplers combined with bathymetrical surveys and adcp measurements. I hope the following reference will be of interest for you.

This is a nice classic paper, you probably know it already,

Thanks for your question. However, I don't understand the meaning of real bed load measurements. In fact, my Indian friend, Harish Gupta, now calculated bed loads for major and small rivers of the world. Please contact him for more information.

Dear all, appreciate all of you for responding to my question and also directing me to some valuable literature.

Dear Selvaraj, thanks for your respond. The "real bed load measurements" means the actual measurement of bed loads in streams rather than calculating them from already measured suspended load. As you have written, Gupatha's approach is likely to calculate bed loads from suspended loads for global rivers. Am I correct ? I would like to read his work if findings have already been published.

If someone is interested to know how bed load and suspended lad are distributed in the total load, I would suggest to read the following paper. It is interesting!

Turowski, J. M., Rickenmannd, D. & Dadson, S. J., 2010, The partitioning of the total sediment load of a river into suspended load and bedload: a review of empirical data.

Sedimentology 57 (4), 1126–1146.

A classic dataset for bedload transport is from Oak Creek. Here is a link to an old webpage as a place to start to track down the data. Unfortunately, t he link to the dataset is broken. Good luck.
