Author: Adedeji, KB ; Abe, BT ; Hamam, Y ; Abu-Mahfouz, Adnan MI ; Shabangu, TH ; Jimoh, AA Date: Feb 2017 The interference effect from high voltage overhead lines on nearby metallic pipelines is a major challenge for utility owners due to the induced AC potentials on metallic pipelines. Nevertheless, numerous mitigation techniques have been ... Read more
Pressure management strategies for water loss reduction in large-scale water piping networks: A review

Author: Adedeji, KB ; Hamam, Y ; Abe, BT ; Abu-Mahfouz, Adnan MI Date: Feb 2018 In water distribution networks (WDNs), water loss through leaking pipes is inevitable, as it constitutes a major threat to the operational services of water utilities. While water utilities are keen to providing an adequate supply of water ... Read more
Real-time dynamic hydraulic model of water distribution networks

Author: Abu-Mahfouz, Adnan MI ; Hamam, Y ; Page, Philip R ; Adedeji, KB ; Anele, AO ; Todini, E Date: Mar 2019 The impact of climate change and increasing urbanisation throughout the world has forced water utility managers to increase the efficiency of water resources. Reduction of real (or physical) water losses plays a crucial role in improving the ... Read more
A review of the effect of AC/DC interference on corrosion and cathodic protection potentials of pipelines

Author: Adedeji, KB ; Ponnle, AA ; Abe, BT ; Jimoh, AA ; Abu-Mahfouz, Adnan MI ; Hamam, Y Date: Dec 2018 Pipelines installed in the energy utility corridor with alternating current (AC) or direct current (DC) sources have attendant problem of induced corrosion. In the past years, AC or DC induced corrosion of metallic pipelines has been a major ... Read more
Solving management problems in water distribution networks: A survey of approaches and mathematical models

Author: Bello, O ; Abu-Mahfouz, Adnan MI ; Haman, Y ; Page, Philip R ; Adedeji, KB ; Piller, O Date: Mar 2019 Modern water distribution networks (WDNs) are complex and difficult to manage due to increased level of urbanization, varying consumer demands, ageing infrastructure, operational costs, and inadequate water resources.
