o:1052 Safety assessment of the existing earth levees: estimation of composition, state and stability en Abstract: In present paper we focus on the procedure for assessment of existing levee composition, state and stability, based on the results of field and laboratory investigation, and following the positive international recommendations in this field. For this purpose, we classify main types of levees in Serbia, including the main categories of levee failure. As a results of research, we propose statistically reliable correlations among the grain size composition, results of penetration tests and specific electrical resistivity, in order to estimate the composition and state of the existing levee. Regarding the stability, we develop separate stability diagrams for assessment of construction and filtration stability, for levees with different composition and geometry, assuming common range of values of input geomechanical parameters. 1552100 978-86-82565-55-0 2022-11-21T08:08:37.667Z 44 no 46 Srđan Kostić Institut za vodoprivredu "Jaroslav Černi" 0000-0002-3705-3080 Dušan Blagojević Institut za vodoprivredu "Jaroslav Černi" person Rajko Vasić Institut za vodoprivredu "Jaroslav Černi" person Olivera Obradović Institut za vodoprivredu "Jaroslav Černi" person Bojan Stanković Institut za vodoprivredu "Jaroslav Černi" person application/pdf 9496350 https://unilib.phaidrabg.rs/o:1052 no yes 1 70 92000004 71A04 Contemporary Water Management: Challenges and Research Directions, Proceedings of the International Scientific Conference in the Honour of 75 Years of the Jaroslav Černi Water Institute, October 19-20 2022, Belgrade 175 190 Jaroslav Černi Water Institute 2022 Received: August 31, 2022 Revision: September 13, 2022 Accepted: September 16, 2022
