The paper develops the ResourcePlan as (i) legal and (ii) a planning instrument to support the efficient use of resources in urban neighborhoods. The integrative, multi-methodological approach addresses the use of natural resources in the building and infrastructural sectors of (i) water (storm- and wastewater) management, (ii) construction and maintenance of buildings and infrastructure, (iii) urban energy system planning, and (iv) land-use planning. First, the development as legal instrument is carried out, providing (i) premises for integrating resource protection at all legal levels and (ii) options for implementing the ResourcePlan within German municipal structures. Second, the evaluation framework for resource efficiency of the urban neighborhoods is set up for usage as a planning instrument. The framework provides a two-stage process that runs through the phases of setting up and implementing the ResourcePlan. (Eco)system services are evaluated as well as life cycle assessment and economic aspects. As a legal instrument, the ResourcePlan integrates resource protection into municipal planning and decision-making processes. The multi-methodological evaluation framework helps to assess inter-disciplinary resource efficiency, supports the spatial identification of synergies and conflicting goals, and contributes to transparent, resource-optimized planning decisions.}, language = {de} } @article{MuellerHagemannAlbayrakAueletal.2020, author = {M{\"u}ller-Hagemann, M. and Albayrak, I and Auel, C and Boes, RM}, title = {Field Investigation on Hydroabrasion in High-Speed Sediment-Laden Flows at Sediment Bypass Tunnels}, series = {Water 12 (2)}, journal = {Water 12 (2)}, publisher = {MDPI}, address = {Basel}, doi = {10.25974/fhms-15126}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-151268}, year = {2020}, abstract = {Wear due to sediment particles in fluid flows, also termed hydroabrasion' or simply 'abrasion', is an omnipresent issue at hydraulic structures as well as in bedrock rivers. However, interactions between flow field, particle motion, channel topography, material properties and abrasion have rarely been investigated on a prototype scale, leaving many open questions as to their quantitative interrelations. Therefore, we investigated hydroabrasion in a multi-year field study at two Swiss Sediment Bypass Tunnels (SBTs). Abrasion depths of various invert materials, hydraulics and sediment transport conditions were determined and used to compute the abrasion coefficients kv of different abrasion models for high-strength concrete and granite. The results reveal that these models are useful to estimate spatially averaged abrasion rates. The kv-value is about one order of magnitude higher for granite than for high-strength concrete, hence, using material-specific abrasion coefficients enhances the prediction accuracy. Three-dimensional flow structures, i.e., secondary currents occurring both, in the straight and curved sections of the tunnels cause incision channels, while also longitudinally undulating abrasion patterns were observed. Furthermore, hydroabrasion concentrated along joints and protruding edges. The maximum abrasion depths were roughly twice the mean abrasion depths, irrespective of hydraulics, sediment transport conditions and invert material.}, language = {en} } @article{TophoffKreyenschulteSchuettrumpfetal.2022, author = {Tophoff, Lukas and Kreyenschulte, Moritz and Sch{\"u}ttrumpf, Holger and Heimbecher, Frank}, title = {Verockerung wasserbaulicher Filteranlagen: Stand der Wissenschaft und notwendige Untersuchungen}, series = {Grundwasser - Zeitschrift der Fachsektion Hydrogeologie}, journal = {Grundwasser - Zeitschrift der Fachsektion Hydrogeologie}, doi = {10.25974/fhms-15293}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-152930}, pages = {1 -- 14}, year = {2022}, abstract = {In den letzten Jahrzehnten kam es in Einzelf{\"a}llen zu schweren Sch{\"a}den an wasserbaulichen geotextilen Filteranlagen infolge der Verstopfung durch ausgeflockte ockerhaltige Produkte.
