Abstract

Based on the observed data, we used the method of analogy years to analysis the effect of middle and small flood control to sediments transport in the TGR. The analogy year is 2007, 2006 and 2008, whose water and sediments condition was similar with the year 2010 to 2012. Compared with the flood season in 2007, 2006 and 2008 successively, the deposition increased 2042 ×104t in the flood season of 2010, which was the 11.4% of deposition in 2010, increased 210 ×104t in the flood season of 2011, which was the 2.3% of deposition in 2011, increased -350 ×104t in the flood season of 2012, which was the 2% of deposition in 2012. The result shows that, in the years with small sediments runoff, the middle and small flood operation can’t increase obvious deposition, but in that years with more sediments runoff, the middle and small flood operation need further optimization.
