Application of Principal-Component Analysis to Long-Term Reservoir Management
Determining the optimal long-term operating policy of a multireservoir power system requires solution of a stochastic nonlinear programming problem. The paper presents a very efficient...

The State of Art of Physical Modelling of Sediment Transport
The paper attempts formula some ideas about the state of the art in the field of physical modelling of sediment transport processes. Up to now the physics of sediment transport are not...

Advances in Computational Mobile-Bed Hydraulics
A new conceptual approach to one-dimensional mobile-bed simulation is briefly described, along with two demonstrative examples. The approach is based on fully coupled solution of the unsteady...

Potential Flow Over a Wavy Bed: A Persistent Error
The standard small-amplitude theory of potential flow over a wavy bed is briefly discussed, together with the three special values of the Froude Number which define four different flow...

Modeling of Contaminant Transport in Rivers with Emphasis on the Interaction with Movable Boundaries
The transport of dissolved and absorbed pollutants is simulated by a one-dimensional convection-diffusion model which particularly accounts for the exchange processes at the river bed...

Friction Slope Computation for Mathematical Models
The behavior of the energy flow gradient as function of depth and velocity is analyzed for three flow resistance methods. In the paper, the necessary modifications introduced to the methods...

Comparison of n Values in Natural and Dredged Channels
