Abstract |
Problems of the unsteady aspects of the flow of water arise in the planning, design, and management of water resources when computations must be made on flood flows, a reservoir regulation, surges in canals, tidal flows, etc. A powerful analytical tool for the investigation of unsteady flows is available in the equations of conservation of mass momentum. Although approximate solutions of these equations have been used on a large scale, the digital computer has made it feasible to obtain complete solutions of the equations by numerical methods. Three methods of solution, the explicit, characteristic, and implicit methods, were investigated and applied to artificial and natural channels. The natural channel selected for this purpose was a reach of the Neuse River, North Carolina. (Author) |
