汇流理论 meaning in Chinese

concentration theory

The main features in the study of flood forecasting and control system are as follows : ( 1 ) runoff generating and confluence theory and hydro - dynamic method are adopted to predict the water level of taihu lake and key nodes , the basin wide forecasting and control system with the function of real time correction has been first established in plain river network to meet the complicated flow conditions of taihu lake basin and to enhance the reliability of forecasting results ; ( 2 ) according to the rainfall in foreseen period multiple schemes can be made in the forecasting model and adjusted with time , which overcomes the errors caused by the uncertain rainfall in the foreseen period so as to make the forecasting results approach reality
本文所研究的预报调度系统有如下特点： ( 1 )本系统采用产汇流理论和水动力学方法预报太湖及重要节点水位，首次在平原河网地区建立了具有实时校正功能的全流域预报调度系统。以适合太湖流域复杂的水力条件，增强预报的可靠性; ( 2 )预报模型可以根据预见期降雨量进行多方案预报，并随时间推移，可以实时进行调整，克服由于预见期降雨不确定引起的误差，使预报结果更接近实际。
