Faculty of Engineering. Dept. of Civil Engineering. Theses -- Civil engineering Dissertations -- Civil engineering Retaining walls Embankments -- Design and construction Channels (Hydraulic engineering) Sediment transport Civil engineering Thesis (MScEng (Civil Engineering))--University of Stellenbosch, 2005. There has always been some debate in the past about the most effective and economical type of revetment to be used to combat or prevent erosion in rivers and channels. Some of the most common materials used for these mitigation measures are gabions, Reno mattresses and rip rap. A study done by the Colorado State University (CSU, 1984), comprised hydraulic tests of Reno mattresses used as a channel bed revetment. The result were compared with those of rip rap. This thesis mainly deals with the evaluation of incipient motion conditions for rock used in Reno mattresses and as rip rap. In this thesis the results of the CSU study and the design criteria of Maccaferri are evaluated and compared with the result obtained when applying the stream power theory and the Shields' theory with respect to incipient motion. This thesis includes the theory with respsect to incipient motion conditions, background to the CSU study and comparisons of the results of the CSU study and Maccaferri's design criteria with theoretical calculations. A cost comparison of Reno mattresses and rip rap as channel bed revetment measures, as well as conclusions and recommendations with regard to the design and use of these options, are also included. The frame of reference for this thesis is the set of CSU test results. The calibrations achieved, proposals made and accuracy of conclusions thus depend on those results. 2008-07-31T09:39:36Z 2010-06-01T09:03:41Z 2008-07-31T09:39:36Z 2010-06-01T09:03:41Z 2005-12 Thesis http://hdl.handle.net/10019.1/3004 en University of Stellenbosch application/pdf Stellenbosch : University of Stellenbosch |
