1. 4 Internet Figure 8 Site component screen The practice table for a particular site component lists all practices that have been entered into the system for that particular type of component eg a surface dust suppression task All practices in the table are categorised as to whether they are implemented on site actual or not potential As per the site practice tables Section 2 1 5 the practice links can lead to either articles or the simulation section If the user has sufficient authorisation there is also the option to record actual practices or add potential practices to a site component as discussed in Sections 4 2 2 1 and 4 5 1 2 1 8 Navigating by Flow Chart If a site has a flow chart navigation of the site can be performed using either the flow chart image or the table of site components In the top right hand corner of the site browsing screen is a button Navigate by FlowChart Click on this button to change the site browsing screen from a satellite photo of the site and a navigation table of site components to an image of a flowchart of the site Figure 9 Each component of the site is coloured by type imports are green stores are blue tasks are grey exports are red treatment plants are yellow and diversions are purple Each of these site components can be clicked to browse to the page for that component To the right of the flow chart there is a legend This shows not only what the colours represents

An environmental officer for a mine site might use WaterMiner to keep records of all systems at the site that involve the management and use of water These records also allow the environmental officer to compare their site with other sites in the region Additionally the system would likely be used to learn about applicable practices to assist with water management and to record the status of practices currently in use on the site This type of CWiMI WaterMiner v2 0 User Manual Page 8 of 84 user might also be interested in running simulations of the current estimated water situation of the site and simulate what impact potential changes in the system could have 1 3 System Requirements and Installation WaterMiner can run on any operating system All that is required is a web browser and an internet connection preferably broad band 1 4 Security Levels The things a WaterMiner user may do in an area of the system are prescribed by their level of access for that area In particular those areas controlled by access level are who may see or edit the catalogue data for each site and who may perform system wide changes Accordingly there is a general level of access for a user and specific levels of access for each site In ascending order of authority the levels are 1 Anonymous 2 Read 3 Write 4 Owner 5 WaterMiner Editor 6 WaterMiner Administrator A user s level of access to a site is determined by the system from t
