In the first topic, the multi-objective optimization of interventions on the network is presented to find trade-off solutions between costs and efficiency. In the second topic, methodologies are presented to simulate and predict demand and to simulate network behavior in emergency scenarios. In the third topic, a methodology is presented for the multi-objective optimization of pump-as-turbine (PAT) installation sites in transmission mains. In the fourth topic, methodologies for pipe burst identification and leakage reduction are presented. As for the urban drainage systems (UDSs), the two explored topics are asset management, with a system upgrade to reduce flooding, and modeling of flow and water quality, with analyses on the transition from surface to pressurized flow, impact of water use reduction on the operation of UDSs, and sediment transport in pressurized pipes. The Special Issue also includes one paper dealing with the hydraulic modeling of an urban river with a complex cross-section. 606 $aHistory of engineering and technology$2bicssc 610 $aactions 610 $aadvection-dispersion equation 610 $aANN 610 $aasset management 610 $achaos theory 610 $aclimate change 610 $aculvert 610 $ademand 610 $adrainage network 610 $adrainage networks 610 $aemergency scenario 610 $aemergency scenarios 610 $aenergy 610 $aenergy recovery 610 $aerosion 610 $afinite volume methods 610 $aflooding 610 $aflow regime transition 610 $agene expression programming 610 $agenetic algorithm 610 $aGIS modeling 610 $ahousehold discharge 610 $ahydraulic 610 $ahydraulic factors 610 $ahydraulic simulation 610 $ahydraulic transients 610 $ahydropower 610 $ain-situ 610 $aintermittent water supply 610 $aKelowna 610 $aleakage 610 $aleakage management 610 $aleakage reduction strategies 610 $alocal approximation 610 $amachine learning 610 $amulti-objective 610 $amulti-objective optimization 610 $aNSGA-II 610 $anumerical oscillations 610 $anumerical simulation 610 $anumerical viscosity 610 $aopen channel 610 $aoptimization 610 $aperformance 610 $apipe bursts 610 $aprediction 610 $aPreissmann slot model 610 $apressure control 610 $apressure pipe 610 $apump as turbine 610 $areal-time control 610 $areduced water consumption 610 $arehabilitation 610 $asediment transport 610 $asediment transport model 610 $asedimentation 610 $asewage 610 $asewer design 610 $astochastic sewer modelling 610 $aSWMM 610 $atotal suspended solids 610 $atransition stretch 610 $atransmission mains 610 $atrapezoidal stretch 610 $aurban drainage system modeling 610 $aurban water network management 610 $avalve closing algorithm 610 $awastewater quality 610 $awater consumption 610 $awater demand 610 $awater distribution networks 610 $awater distribution system modeling 610 $awater distribution systems 610 $awater management 610 $awater network partition 610 $awater quality 610 $awater system 610 $awater utility 610 $aWaterGEMS software 610 $aweb 2.0 615 7$aHistory of engineering and technology 700 $aCreaco$b Enrico$4edt$01281245 702 $aCampisano$b Alberto$4edt 702 $aCreaco$b Enrico$4oth 702 $aCampisano$b Alberto$4oth 906 $aBOOK 912 $a9910557142503321 996 $aAdvances in Modeling and Management of Urban Water Networks$93022600 997 $aUNINA
