Prediction of Water Inflow in Subsea Tunnels under Blasting Vibration [PDF]
Water, 2018 The subsea tunnel of Qingdao metro line 1 has been excavated using the drill and blast method. Blasting vibration during tunneling may cause larger water inflow and even severe security risks and considerable economic losses. However, the prediction of water inflow in subsea tunnels under blasting vibration still remains a challenging problem.

ON-LINE DESIGN OF WATER RESERVOIR POLICIES BASED ON INFLOW PREDICTION [PDF]
IFAC Proceedings Volumes, 2008 Abstract Stochastic Dynamic Programming (SDP) is the method most extensively adopted to design release policies for water reservoir networks. However, it suffers of the well known “curse of dimensionality”, which actually limits its applicability to small reservoir networks.
