“…However it is important to understand how development patterns in specific watersheds affect water quality (Fu et al, 2009). Aside from a concentrated source of BOD, warmer waters originating from urban areas will lower the oxygen carrying capacity of urban rivers and accelerate processes of chemical degradation threatening fish survival.…”

Using historical data of: climate, land-use, hydrology and water quality from four catchments located in the south of England, this study identifies the impact of climate and land-use change on selected water quantity and water quality indicators. The study utilises a paired catchment approach, with two catchments that have experienced a high degree of urbanisation over the past five decades and two nearby, hydrologically similar, but undeveloped catchments. Multivariate regression models were used to assess the influence of rainfall and urbanisation on runoff (annual and seasonal), dissolved oxygen levels and temperature. Results indicate: (i) no trend in annual or seasonal rainfall totals, (ii) upward trend in runoff totals in the two urban catchments but not in the rural catchments, (iii) upward trend in dissolved oxygen and temperature in the urban catchments, but not in the rural catchments, and (iv) changes in temperature and dissolved oxygen in the urban catchments are not driven by climatic variables.

“…The integrated model is able to simulate various hydraulic and biochemical processes of the three sub-systems in a single simulation environment. It has been used for development of multi-objective control strategies (Fu et al 2008), impact analysis of urbanization (Fu et al 2009), and development of mitigation measures for urbanization (Fu et al 2010). This paper will use the integrated model to investigate the impacts of rainfall events on receiving water quality and assess the system performance in terms of compliance probabilities of chosen water quality indicators.…”

“…There is increasing concern about river water quality in the recent years in relation to the adverse impacts from population growth, land use change, and climate change (He et al 2008;Semadeni-Davies et al 2008a,b;Fu et al 2009). New legislation has been introduced worldwide to protect surface water quality, human health and aquatic environment.…”

In recent years integrated models have been developed to simulate the entire urban wastewater system, including urban drainage systems, wastewater treatment plants, and receiving waterbodies. This paper uses such an integrated urban wastewater model to analyze the frequency of receiving water quality in an urban wastewater system with the aim of assessing the overall system performance during rainfall events. The receiving water quality is represented by two indicators: event mean dissolved oxygen concentration and event mean ammonium concentration. The compliance probability of the water quality indicators satisfying a specific threshold is used to represent the system performance, and is derived using the rainfall events from a series of 10 years' rainfall data. A strong correlation between the depth of each rainfall event and the associated volume of combined sewer overflow (CSO) discharges is revealed for the case study catchment, while there is a low correlation between the intensity/duration of the rainfall event and the volume of the CSO discharges. The frequency analysis results obtained suggest the event mean dissolved oxygen and ammonium concentrations have very different characteristics in terms of compliance probabilities at two discharging points for combined sewer overflow and wastewater treatment plant effluent, respectively. In general, the simulation results provide an understanding of the performance of the integrated urban wastewater system and can provide useful information to support water quality management.

“…The latter and the increase in computational power promoted the use of Monte Carlo simulations and the study of input uncertainty propagation through the model either during the model development process or during model use (e.g. Astaraie-Imani et al, 2012;Benedetti et al, 2008;Benedetti et al, 2010;Freni et al, 2011;Fu et al, 2009b). Long term simulations can be conducted as well, including the study of integrated control (e.g.…”
