sediment transport analisa

[wisanggeni]

when i perform sediment transport analisa with hec ras 4 beta it give me very high aggradation on cross section just sfter junction.........
Can anybody give me solution?

run your hydrograph a little longer to allow the bed to mix. it could be a result of two very different gradations meeting a junction where one fraction/ gradation is very mobile and passes through, meeting the capacity, and the rest falls out. if you allow them to mix, you may get more realistic results.

if the gradations are the same, the above is probably useless
