Research into the Positional Erosion around Bridges Abutments in the Garmian Region

In this research, investigation the impact of water levels, velocity on drift depth pillars bridges in Garmian region was studied. The levels and were recorded for periods, different stretches between months December 2018 March 2019. study dealt with most important postural relationships that can be used to estimate future around pillars. Description site studying within includes measurements bridge span, height Hydraulic properties basins studied as well soil texture depending clay, silt sand portions detected. erosion did not exceed critical limit some because it reach foundation, while foundation others flow abutments Dardween Bridge is a type, so high drifts are -+expected. results gradient examination size particles region, shows proportions Coarse Fine aggregates "gravel sand" which increasing porosity permeability soil, thus possibility at bases supports area due seepage. A proposal method obtained by current Using deep piles foundations pillar instead rock dam front pile reduce recommended study.
