background and aims: the main cause of many problems in developing countries is related to the provision of safe drinking water. since the health of drinking water is important in the busy centers such as hospitals, clinics and health centers, this study was done to investigate the role of water coolers connected to the municipal system in microbial quality of drinking water in behbahan city. m...

the paper presents the case study of the current formation of a brazilian pit lake from an iron ore mining activity. the water used for the filling of the lake comes from rain, ground water and the complementary pumpage from a close river. at its final stage, which will be reached around year 2018, lake aguas claras will have a surface area of 0.67 km2 and the depth of 234 m, which will make it...

Mathematical models are well known as useful tools for water management practices, directly or indirectly related to the implementation of the Water Framework Directive (WFD) in European countries. They can be applied to solve or understand either simple water quality problems or complex water management problems of trans-boundary rivers or multiple-purpose and stratified reservoirs. Accidental...

A case study on the application of the River Water Quality Model No. 1 (RWQM 1) is presented in order to illustrate the importance of modelling a sediment compartment for an ecologically meaningful assessment of the impact of wastewater effluents and combined sewer overflows. The focus of this case study is on the compartmentalisation approach of the RWQM 1 that makes such a description possibl...

The paper applies an algorithm for recursive estimation of variables and parameters in general dynamic networks that has been developed by [Brdys 99] to robust on-line monitoring of the mixing water quality in dynamic water networks. A complete hydraulic information is assumed to be available on-line. First a parsimonious parametrisation of a mathematical model of mixing quality is derived. Nex...

This paper is concerned with the integrated modelling, and control of urban wastewater systems (UWS) comprising the wastewater treatment plants (WTP), receiving waters (river) and the sewer networks. A unified framework is developed and simple models are used and implemented in Matlab/Simulink to produce a toolbox. Novel linear and nonlinear control structures are then proposed to design integr...

Global climate change and growing urbanization pose a threat to both natural urban ecosystems. In these, one of the most impacted elements is water, which responsible for large variety ecosystem services benefits society. Mathematical models can be used simulate implementation Nature-Based Solutions (NBSs), thus helping quantify these issues in practical efficient manner. This paper presents ra...
