I appreciate more, Of course the allowable tolerance for water surface calculation is minimum 0.1mm which is acceptable to my profile computation with 1.2m wide and 0.28m dip flume flow, we can take as small (field) irrigation canal. and I read one literature that compares the flume flow with in...
Thank you gbam, I appreciate your response. yes, I observed that it is better to add sections in b/n.
By the way, considering small scale flow systems(Eg. lab. flume flow), is that possible to simulate using HECRAS with the actual scale better than large scale taking a big scale ratio?
Dear gbam,
Really thank you so much for your attention, I put these 4 sections considering some engineering judgements. However, I put several sections in between section 1&2 and 3&4 by interpolation (the reach has uniform shape). Because i need these points and also i put ineffective flow area...
Thank you cvg. but i need to elaborate for me that HECRAS manual recommends to provide "enough" x-section in these reaches and the word enough is not clear for the number per length of contraction and expansion length. so, prviding more sections there can have side effect on computation or we...
My x-section for the entire reach (having bridge at the middle) is the same. Is there disadvantage in accuracy of water surface computation if i provide more x-sections especially near bridge? please can you give me hint or direct a reference?
Thanks
