TLDR
CITY DRAIN was developed in the Matlab/Simulink (C) environment, enabling a block wise modelling of the different parts of the urban drainage system (catchment, sewer system, storage devises, receiving water, etc.).Abstract:
In the last years design procedures of urban drainage systems have shifted from end of pipe design criteria to ambient water quality approaches requiring integrated models of the system for evaluation of measures. Emphasis is put on the improvement of the receiving water quality and the overall management of river basins, which is a core element of the Water Framework Directive (WFD) as well. Typically, it is not necessary to model the whole variety of effects on the receiving water but to focus on the few dominating ones. Only pollutants and processes that have a direct and significant influence on the selected impacts need to be described quantitatively, whereas all other processes can be neglected. Hence, pragmatism is required to avoid unnecessary complexity of integrated models. This is as well true for software being used in daily engineering work, requiring simplicity in handling and a certain flexibility to be adjusted for different scenarios. CITY DRAIN (C) was developed to serve these needs. Therefore it was developed in the Matlab/Simulink (C) environment, enabling a block wise modelling of the different parts of the urban drainage system (catchment, sewer system, storage devises, receiving water, etc.). Each block represents a system element (subsystem) with different underlying modelling approaches for hydraulics and mass transport. The different subsystems can be freely arranged and connected to each other in order to describe an integrated urban drainage system. The open structure of the software allows to add own blocks and/or modify blocks (and underlying models) according to the specific needs. The application of CITY DRAIN is shown within the integrated modelling case study Vils/Reutte. Further additional applications for CITY DRAIN, including batch simulations, real time control (RTC) and model based predictive control (MBPC) are presented and discussed.read more

Dynamic influent pollutant disturbance scenario generation using a phenomenological modelling approach
TL;DR: A simple phenomenological modelling approach is proposed as an alternative to generate dynamic influent pollutant disturbance scenarios and can be expanded to other applications, for example to represent heavy metal or organic micro-pollutant loads entering the treatment plant.

Performance and sensitivity analysis of stormwater models using a Bayesian approach and long-term high resolution data

TL;DR: The performance and parameter sensitivity of stormwater models with different levels of complexities are presented using the formal Bayesian approach, finding that the effective impervious fraction is the most important parameter in both models while both were insensitive to dry weather related parameters.

An integrated model for water management in a rapidly urbanizing catchment
TL;DR: The results indicate that SyDWEM has the capacity to predict the socio-economic and environment changes at a catchment scale under proposed socio- Economic and population growth, water resource supply and depletion as well as environmental changes, especially in analyzing long-term scenarios of urbanization.

Modelling and real-time control of the integrated urban wastewater system
TL;DR: It can be concluded that there are tools available to help dealing with the operational consequences of the WFD, and an immission-based control strategy is developed for a particular case study and is shown to be able to improve the water quality compared to the uncontrolled case.

Integrating simulation models with a view to optimal control of urban wastewater systems
David Butler,Manfred Schütze +1 more
TL;DR: It is argued that it is now feasible to operate complete urban wastewater systems to maximize river water quality directly using the software and techniques outlined, and simulation results indicate the clear potential of integrated control even for catchments where local control provides hardly any benefits.
