EART63012 Pollution Management in Practice 2
Week One: Surface Water Systems 1. Outcomes: define the different types of artificial influences on flows; evaluate the different types of abstractions and discharges; explain why sustainable abstractions are important and why environmental permits to discharge are needed; explain the impacts of reservoir releases on riverine environments; define the different methods to naturalise flows which have been artificially influenced; explain about environmental flows; use different techniques to naturalise a flow time series at a river gauge to account for artificial influences upstream; practice using techniques to produce a naturalised flow time series for a gauge on the Xianhe River in China to estimate environmental flows requirements. 2. Lecutre 2.1 introduction 略 2.2 Artificial influences on flows Q: 1. What types of artificial influences affect river flows? 2. What are abstractions from rivers used for? 3. What impact do abstractions have on river flows? 4. Why are sustainab
