T1  - In-situ Monitoring großer dezentraler Behandlungsanlagen für Niederschlagsabflüsse
T2  - 12. Rostocker Abwassertagung - Emissionsminderung von Punktquellen im ländlichen Raum / Jens Tränckner (Hrsg.)
N2  - Der Behandlung von Niederschlagsabflüssen aus Trennsystemen kommt zur Zielerreichung eines wirksamen Gewässerschutzes eine wesentliche Rolle zu. Konventionelle, zentrale Anlagen behandeln den Abfluss vor der Einleitung in das Gewässer. Zunehmend an Bedeutung gewonnen haben dezentrale Anlagen, die den Abfluss am Entstehungsort behandeln. Unterschiedlich belastete Oberflächenabflüsse können somit den wasserrechtlichen Anforderungen entsprechend gezielt behandelt werden. Voraussetzung zur Anwendung ist der Nachweis der vergleichbaren Reinigungsleistung zu zentralen Anlagen. In-situ Gütemessungen der Zu- und Ablauffrachten einer Behandlungsanlage ermöglichen eine datenbasierte Bewertung der Anlagenwirksamkeit.

T1  - Statistical Distribution of TSS Event Loads from Small Urban Environments
JF  - Water
N2  - Results from a long-term stormwater quality monitoring program were used to derive total suspended solids (TSS) event load distributions at four small urban environments (flat roof, parking lot, residential catchment, high traffic street). Theoretical distribution functions were fitted to the empirical distribution functions obtained. Parameters of the theoretical distribution functions were optimized with respect to a likelihood function to get both optimized parameters and standard errors. Kolmogorov-Smirnov and Anderson-Darling test statistics were applied to assess the goodness-of-fit between empirical and theoretical distribution. The lognormal distribution function was found to be most expressive to approximate empirical TSS event load distributions at all sites. However, the goodness-of-fit of the statistical model strongly depends on the number of events available. Based on the results of a Monte-Carlo-based resampling strategy, around 40 events should be considered.

T1  - Distribution-Based Calibration of a Stormwater Quality Model
JF  - Water
N2  - Stormwater quality models are usually calibrated using observed pollutographs. As current models still rely on simplified model concepts for pollutant accumulation and wash-off, calibration results for continuous pollutant concentrations are highly uncertain. In this paper, we introduce an innovative calibration approach based on total suspended solids (TSS) event load distribution. The approach is applied on stormwater quality models for a flat roof and a parking lot for which reliable distributions are available. Exponential functions are employed for both TSS buildup and wash-off. Model parameters are calibrated by means of an evolutionary algorithm to minimize the distance between a parameterized lognormal distribution function and the cumulated distribution of simulated TSS event loads. Since TSS event load characteristics are probabilistically considered, the approach especially respects the stochasticity of TSS buildup and wash-off and, therefore, improves conventional stormwater quality calibration concepts. The results show that both experimental models were calibrated with high goodness-of-fit (Kolmogorov–Smirnov test statistic: 0.05). However, it is shown that events with high TSS event loads (>0.8 percentile) are generally underestimated. While this leads to a relative deviation of −28% of total TSS loads for the parking lot, the error is compensated for the flat roof (+5%). Calibrated model parameters generally tend to generate wash-off proportional to runoff, which is indicated by mass-volume curves. The approach itself is, in general, applicable and creates a new opportunity to calibrate stormwater quality models especially when calibration data is limited.

T1  - Assessing the Performance of Decentralised Stormwater Management Measures by means of Continuous Turbidity Measurement
T2  - Novatech 2019 - 10th international conference on Urban Water – Strategies and solutions for sustainable management
N2  - The in-situ performance of large decentralised stormwater treatment systems is investigated by means of continuous turbidity measurements. Turbidity measurements are used as a surrogate to continuously estimate Total Suspended Solid (TSS) concentrations. TSS event loads are calculated at the inlet and outlet of two stormwater treatment systems, which both are installed at the outlet of catchments with high pollution potential. The event-specific performance is defined as ratio between TSS loads of inflow and outflow. Based on measurement data obtained, the overall TSS load retention efficiency is about 32 %.

JF  - Urban Water Journal
N2  - The stormwater management model SWMM of the US EPA is widely used to analyse, design or optimise urban drainage systems. To perform advanced analysis and visualisations of model data this technical note introduces the R package swmmr. It contains functions to read and write SWMM files, initiate simulations from the R console and to convert SWMM model files to and from GIS data. Additionally, model data can be transformed to produce high quality visualisations. In accordance with SWMM’s open source policy the package can be obtained through github.com or the Comprehensive R Archive Network (CRAN).

T1  - The ResourcePlan — An Instrument for Resource-Efficient Development of Urban Neighborhoods
JF  - Sustainability
N2  - In Germany, the current sectoral urban planning often leads to inefficient use of resources, partly because municipalities lack integrated planning instruments and argumentation strength toward politics, investors, or citizens. 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.

N2  - Im Rahmen einer nachhaltigen Stadtentwicklung wird der Vegetation die
Funktion der Beschattung und Verdunstung zugesprochen. Der Stadthydrologie fehlte hierfür bislang ein geeignetes Simulationsmodell. Der entwickelte Modellbaustein SWMM-UrbanEVA erlaubt die standortgerechte Simulation der Verdunstung von Vegetation im urbanen Raum. Für Freiflächen erfolgt die Prozessmodellierung des Energie- und Wasserhaushaltes des Systems Boden-Pflanze-Atmosphäre. Mit meteorologischen und vegetationskundlichen Kenndaten wird eine raum-zeitlich differenzierte Berechnung ermöglicht.
