Design and development of Decision Support Platform for Comprehensive Management of Dissolved Oxygen in Typical Reaches of the Pearl River Delta
In order to meet the requirement of dissolved oxygen control in the Pearl River Delta,Decision Support Platform for Comprehensive Management of Dissolved Oxygen in Typical Reaches of the Pearl River Delta was designed and developed based on the structure of the decision support system using tools such as geographic information systems,databases,and models.The platform displayed the dissolved oxygen level of key sections in the Pearl River Delta and its impact mechanism using dynamic charts.It realized the rolling forecast and early warning of low dissolved oxygen in key sections of the Pearl River Delta through model integration.Comprehensive control measures such as precise source control,ecological restoration,water resource allocation,and sluice dispatching for possible low oxygen problems in the forecast can be proposed,and the effect of the measures on the concentration of dissolved oxygen can be predicted.The platform can provide technical support for meeting the dissolved oxygen standards in the Pearl River Delta river network area.
