This paper presents the application of the object-oriented framework SMILE to the management of flows and water quality in the Upper Mersey river catchment. The design river flows are those exceeded for 95% of the time, and are estimated applying alternative methods. The influence of compensation reservoirs, surface-water abstractions, and continuous discharges on low river flows is quantified. The annual licensed abstraction volumes are further reviewed. The monitored river water quality is classified using the River Ecosystem scheme. The compliance of the sewage treatment works and trade effluents with their discharge-consent limits is also assessed. The impact of effluents on the variation of river water quality is evaluated through Monte Carlo simulations at the discharge points. The points where the downstream water quality fails to comply with proposed River Quality Objectives are identified. The consent limits of the corresponding discharges are assessed, and changes to the BOD and total ammonia limits are suggested.
本文介绍了面向对象框架SMILE在默西河流域上游水流与水质管理中的应用。设计河流量是指95%时间内超过的流量，并采用替代方法进行估算。量化了补偿水库、地表水抽取和持续排放对低河流量的影响。进一步审查了年度许可抽取量。使用河流生态系统方案对监测到的河流水质进行分类。还评估了污水处理厂和工业废水排放是否符合其排放许可限值。通过在排放点进行蒙特卡罗模拟，评估废水对河流水质变化的影响。确定下游水质不符合拟议河流质量目标的点。评估相应排放的许可限值，并建议改变生化需氧量和总氨限值。
