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 %.

T1 - Ein SWMM-Baustein für die Berechnung der Evapotranspiration von urbaner Vegetation T2 - Tagungsband Aqua Urbanica 2019 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.

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.

Proceedings of the 11th International Conference on Urban Drainage Modelling N2 - The water balance of urban areas differs considerably from the landscape water balance. Increased surface runoff, reduced groundwater recharge and evaporation change the hydrological regime, the morphology and ecology of water bodies close to the cities, the groundwater in the urban area and the urban climate. Today's urban drainage systems are designed to prevent, reduce, drain, seep away, evaporate or discharge precipitation into nearby surface waters with considerable delays. In doing so, it follows the principles of the German Water Resources Act (WHG) and the objectives of the relevant technical regulations DWA-A 102 to keep changes in the natural water balance by settlement activities as low as ecologically, technically and economically acceptable. A reference for the "natural" water balance has to be defined as a planning objective in order to quantify the hydrological changes in settlements. As a suitable reference, we propose to use the water balance of the landscape of the associated ecoregion with today's cultural land use without urban developments. This approach is more suitable to define local conditions than the water balance of the enclosed catchment. The presented calculation approach to define reference values of the water balance, uses soil and geological properties, precipitation and climate data and can be implemented and applied uniformly throughout Germany. The water balances in this study are simulated with the water balance model RoGeR. In this study, the developed approach is applied for five locations in Germany.

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).
