Furthermore, there are no mixed NSMs that can be applied to a small watershed at a minute scale in urban areas.…”

“…Various real-time control (RTC) techniques of hydraulic facilities have been classified as independent NSMs, NSMs combined with SMs (combined measures), and NSMs combined with the same type of NSMs (integrated NSMs). Most RTC techniques in urban areas are independent NSMs for urban drainage facilities [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Several studies such as combined measures have been introduced to increase the efficiency of urban drainage systems (UDSs) [1,17].…”

A Methodology for the Design of RTC Strategies for Combined Sewer Networks

“…Considering network links based on the individual flow capacity of these links (Q), assuming that links with significantly lower capacity than their upstream (US) and downstream (DS) neighbors form suitable locations for the installation of actuators [4]. Studies applying simplified models (e.g., [24,[43][44][45][46]) often inherently use this approach, as they use 'throttle devices' as control locations, e.g., as outflow of storage basins. This approach can thus be seen as the one most frequently documented in literature.…”

“…Interestingly, the identification of a higher number of control locations using the volume-based approach still leads to slightly higher average volume per control location when compared to both existing and flow-based locations (Figure 3b). This indicates a higher efficiency of the volume-based approach, while it appears that existing and flow-based choice of locations is predominant in literature (e.g., [4,24,30,[39][40][41][42][43]45,46]), where the choice of control locations does not form an explicit research topic. It also means that general conclusions about the RTC potential based on the number of control locations alone should be refrained from: the positioning of the individual control locations within the network and with respect to each other is of high relevance.…”

Convertible Operation Techniques for Pump Stations Sharing Centralized Reservoirs for Improving Resilience in Urban Drainage Systems

“…Real time control of urban drainage systems was investigated, with the additional efforts needed by this approach were highlighted through a comparison with conventionally operated systems [6]. The real-time operation of a sewer network was optimized using a multi-goal objective function [7]. An optimized adaptive network-based fuzzy inference system was recommended for the intelligent real-time operation of a pump station in an urban drainage system [8].…”
