“…In fact, dredged sediments combined with biosolids can considerably improve soil fertility and support plant growth as it was shown for Chicago [9]. Technosols constructed from water treatment station sediments and composts had high nutrient contents and showed a positive dynamics in formation of stable aggregates [18,59]. Mixing sediments with clay loam, sand, and peat in volumetric proportions 25/30/40/5 or 15/40/40/5 at the pilot project in Moscow allowed constructing Technosols, whose quality satisfied governmental ecological and health standards [59][60][61].…”

“…A mixture of compost, peat, and sand is recommended for planting trees at the roadsides in Rome [17]. In France, topsoil removed from agricultural and forest lands remains a key material for urban greening [15], whereas reusing the industrial by-products, wastes, and fine sediments is suggested as an environmentally friendly alternative [12,18]. In the United States, particularly in Chicago, biosolids and dredged sediments are implemented for renovation and greening works [9,14].…”

Urbanization results to a wide spread of Technosols. Various materials are used for Technosols’ construction with a limited attention to their ecosystem services or disservices. The research focuses on the integral assessment of soil-like materials used for Technosols’ construction in Moscow megalopolis from the ecosystem services’ perspective. Four groups of materials (valley peats, sediments, cultural layers, and commercial manufactured soil mixtures) were assessed based on the indicators, which are integral, informative, and cost-effective. Microbial respiration, C-availability, specific respiration, community level physiological profile, and Shannon’ diversity index in the materials were compared to the natural reference to assess and rank the ecosystem services and disservices. The assessment showed that sediments and low-peat mixtures (≤30% of peat in total volume) had a considerably higher capacity to provide C-sequestration, climate regulation and functional diversity services compared to peats and high-peat mixtures. Urban cultural layers provided ecosystem disservices due to pollution by potentially toxic elements and health risks from the pathogenic fungi. Mixtures comprising from the sediments with minor (≤30%) peat addition would have a high potential to increase C-sequestration and to enrich microbial functional diversity. Their implementation in urban landscaping will reduce management costs and increase sustainability of urban soils and ecosystem.

La gestion des déchets est complexe et doit pouvoir intégrer les volets (i) économique, (ii) environnemental et (iii) territorial en sus des traditionnels aspects (iv) technique et (v) réglementaire afin de s'insérer dans le concept de l'économie circulaire et le rendre opérationnel. La littérature scientifique montre que ces aspects sont rarement traités ensemble et il est difficile pour les décideurs opérationnels de choisir entre différentes installations de valorisation, en se basant sur une analyse complète. Forte de ce constat, la R&D du groupe EDF travaille à l'élaboration d'un outil permettant de faciliter cet arbitrage. À partir de la méthodologie Analytic Hierarchy Process (AHP), vingt-deux critères qualitatifs et quantitatifs et l'avis d'une quarantaine d'experts (industriels, institutionnels et académiques), l'outil élaboré compare des installations de gestion de déchets en tenant compte des cinq dimensions citées précédemment. Dans cet article, nous proposons cette méthode de comparaison pour cinq voies de valorisation plausibles dans le cas d'une gestion à terre des sédiments du Rhin, dragués dans le domaine hydroélectrique concédé à EDF. Les performances des installations comparées varient selon les dimensions et l'outil donne la possibilité aux décideurs opérationnels de choisir, selon leur perception du contexte, une installation à partir du meilleur compromis entre les cinq aspects étudiés. Ainsi, le gestionnaire de sédiments et plus largement le gestionnaire de déchets peut argumenter une décision et dispose d'une base de discussion et de réflexion avec les différents services internes et externes concernés.

“…Sedimentation of dam reservoirs reduces the effect of flood control by the reservoir. Accumulation of sediment near the dam site may reduce its stability [FOURVEL et al 2018]. Erosion and foaming downstream of the dam may cause the dam foundation to fall out and become unstable.…”

Dam construction is one of the measures that is inevitable in many cases and must be done to supply drinking water, agricultural uses and electricity generation. There are many challenges to a successful dam project, and the managers of each project must consider the appropriate solutions for them. One of the studies that is done in dam design is sedimentation in dam reservoirs. The experimental area-reduction method is a very common technique that obtains the sediment distribution in depth and longitudinal profile. This technique shows that sediment accumulation is not limited to the bottom reservoirs. Sediment accumulation in a reservoir is usually distributed below the top of the protection reservoir or normal water level. In this study, the distribution of sediment in the reservoir of Karun Dam after a period of 65 years has been done using the experimental area-reduction method. Elevation-volume and elevation-area curves of the dam reservoir are obtained after the useful life of the dam and sediment deposition. The results showed that after 65 years, 106.47•10 6 m 3 of sediment is deposited in the reservoir of the dam and the useful volume of the reservoir is significantly reduced. Also, up to a height of 36.4 m, the dam reservoir is filled with sediment. Therefore, no valve should be placed up to this height.
