Abstract


The river flood-plain soil is sedimentation material that they were brought the river stream. The materials settling in consequence of overflowing the river water where flooding the river flood-plain. And by degree it will increase the flood-plain elevation and finally it will change the river patch, because it was happened the swallowing river. By the study of the land density on Kali Wulan’s flood-plain can be obtained the soil technical data to be exploited as the hoarder soil material in mechanic stabilization method (proctor standard density test), can be obtained the average soil density increased of 13,59% from the average final dry soil volume weight = 1,384 grams/cm3, while decreasing the average pore number of 25,8% with the average optimum water content rate = 30,30%. The thickness of soil layer until 4,1 meters were potentially for hoarder soil material.
