摘要：

The equal width (EW) equation is solved by a least-squares technique using linear space-time finite elements. In simulations of the migration of a single solitary wave this algorithm is shown to have good accuracy and conservation. The development of solitary waves from an arbitrary initial condition within an EW environment is examined. (C) 2000 Elsevier Science S.A. All rights reserved. IDT: 35Q20; 65N30; 65N35; 761325.
