Climate-driven QMRA model for selected water supply systems in Norway accounting for raw water sources and treatment processes
Mohammed, Hadi; Seidu, Razak (Peer reviewed; Journal article, 2019)Formulating effective management intervention measures for water supply systems requires investigation of potential long-term impacts. This study applies an integrated multiple regression, random forest regression, and ... -
Comparative predictive modelling of the occurrence of faecal indicator bacteria in a drinking water source in Norway
Mohammed, Hadi; Hameed, Ibrahim A.; Seidu, Razak (Journal article; Peer reviewed, 2018)Presently, concentrations of fecal indicator bacteria (FIB) in raw water sources are not known before water undergoes treatment, since analysis takes approximately 24 h to produce results. Using data on water quality and ... -
Comparison of Adaptive Neuro-Fuzzy Inference System (ANFIS) and Gaussian Process for Machine Learning (GPML) Algorithms for the Prediction of Norovirus Concentration in Drinking Water Supply
Mohammed, Hadi; Hameed, Ibrahim A.; Seidu, Razak (Chapter, 2017)Monitoring of Norovirus in drinking water supply is a complicated, rather expensive, process. Norovirus represent a leading cause of acute gastroenteritis in most developed countries. Modeling of general microbial occurrence ... -
Detection of Water Safety Conditions in Distribution Systems Based on Artificial Neural Network and Support Vector Machine
Mohammed, Hadi; Hameed, Ibrahim A.; Seidu, Razak (Peer reviewed; Journal article, 2019)This study presents the development of artificial neural network (ANN) and support vector machine (SVM) classification models for predicting the safety conditions of water in distribution pipes. The study was based on 504 ... -
Dynamic segment criticality analysis: A precursor to scheduling of maintenance routines in water distribution networks
Tornyeviadzi, Hoese Michel; Mohammed, Hadi; Seidu, Razak (Peer reviewed; Journal article, 2022)This study proposes a framework for dynamic segment criticality analysis and its implications on scheduling of some reactive maintenance routines in water distribution networks (WDNs). The framework harmonises multilayer ... -
Impact of Climate Forecasts on the Microbial Quality of a Drinking Water Source in Norway Using Hydrodynamic Modeling
Mohammed, Hadi; Longva, Andreas; Seidu, Razak (Journal article; Peer reviewed, 2019)This study applies hydrodynamic and water quality modeling to evaluate the potential effects of local climate projections on the mixing conditions in Lake Brusdalsvatnet in Norway and the implications on the occurrence of ... -
Kartlegging av forurensning og rensegrad ved Aspøya renseanlegg
Stensås, Andreas; Drønnen, Fride; Völker, Simon F. (Bachelor thesis, 2023)Ålesund kommune engasjerte NTNU til å utføre en oppgave om kartlegging av forurensning og rensegrad ved Aspøya renseanlegg (RA2). Renseanlegget skal tilfredsstille kravene fra forurensningsforskriften om minst 20% reduksjon ... -
Modelling the effects of climate projections on pathogen infection risks in selected water supply systems in Norway
Mohammed, Hadi (Doctoral theses at NTNU;2019:111, Doctoral thesis, 2019)Abstract Presently, there is a consensus among scientists and policy makers that the occurrence of climate change is unequivocally clear. Erratic and extreme variations in climate variables are commonly associated with ... -
Modelling the impact of water temperature, pipe, and hydraulic conditions on water quality in water distribution networks
Mohammed, Hadi; Tornyeviadzi, Hoese Michel; Seidu, Razak (Peer reviewed; Journal article, 2021)Identifying and controlling the drivers of change in the quality of water within distribution systems requires a comprehensive understanding of the individual and interactive effects of relevant factors. This article ... -
