Salinity Time Series Prediction and Forecasting Using Dynamic Neural Networks in the Qiantang River Estuary [PDF]

Advanced Science Letters, 2012
The early warning of saltwater intrusion is an important work for ensuring the drinking water supplies. To forecast and predict the daily maximum salinity for the water withdrawn for the waterworks located along the Qiantang River, the nonlinear autoregressive networks with exogenous inputs (NARX) model was applied.

Stochastic Analysis and Simulation for Seawall Engineering on Qiantang Estuary

2004
Qiantang River is a famous macro-tidal estuary, and the beach is changing greatly and rapidly by the action of flood and tide. The problem about erosion of flat in front of seawall has still not been solved in theoretically and practically. Based on the theory of reliability, the flat level in front of seawall is firstly considered as a random variable

Effect of large-scale reservoir and river regulation/reclamation on saltwater intrusion in Qiantang Estuary

Science in China Series B: Chemistry, 2001
By using field salinity data recorded in the Qiantang Estuary for the nearly forty years (which covers the periods before and after the erection of a large-scale reservoir in the watershed and river regulation/reclamation in the estuary) and one-dimensional salt water intrusion modeling, it is shown that the salt water intrusion decreases caused by ...

Impact of human activity on the estuary of the Qiantang River and the reclamation of tidal flats and river regulation

Environmental Geology, 2005
The swing of the main channel of the Qiantang River is controlled by the high-water and low-water changes in the river, as well as the impact of large-scale reclamation of tidal flats. Its evolution in modern times is the result of the combined functions of natural and man-made factors.

Prediction of Salinity in Qiantang Estuary Based on Wavelet Neural Network Optimized by Particle Swarm Optimization

Applied Mechanics and Materials, 2013
Saltwater intrusion is a serious problem for most of macro-tidal estuaries, especially when it happened at the downstream region of drinking water sources. Therefore, accurate prediction of salinity variation becomes absolutely necessary. A three-layer salinity prediction model is established in this paper, based on wavelet neural network (WNN ...

Structures of Lateral Flow and Turbulence in a Breaking Tidal Bore Rushing through a Curved Channel of the Qiantang Estuary

Journal of Physical Oceanography
Abstract Tidal bores form in distinct funnel-shaped estuaries and bays initially and cause unique flow and turbulence dynamics when passing through meandering channels, such as in the Qiantang Estuary, Amazon River Estuary, and Seine River Estuary. To understand the lateral currents and turbulence processes of tidal bores in curved channels, velocity ...
