Optimizing the operation of a multireservoir system is challenging due to the high dimension of the decision variables that lead to a large and complex search space. A spectral optimization model (SOM), which transforms the decision variables from time domain to frequency domain, is proposed to reduce the dimensionality. The...
A 2 week field experiment investigated the hydrodynamics of a strongly tidally forced tropical intertidal reef platform in the Kimberley region of northwestern Australia, where the spring tidal range exceeds 8 m. At this site, the flat and wide (∼1.4 km) reef platform is located slightly above mean sea level,...
This paper presents a dimensional analysis for determining optimal flow discharge and optimal penstock diameter when designing impulse and reaction turbines for hydropower systems. The aim of this analysis is to provide general insights for minimizing water consumption when producing hydropower. This analysis is based on the geometric and hydraulic...
This paper presents a case study on the application of a dynamic framework for the intelligent
control of flooding in the Boise River system in Idaho. This framework couples a robust
and numerically efficient hydraulic routing approach with the popular multi-objective Non-dominated
Sorting Genetic Algorithm II (NSGA-II). The novelty of...
The model presented herein is the same as that of Leon et al. (2010b), except that it has been
modified to preserve "lake at rest" conditions in sloped prismatic conduits. The results of the
new model (present paper) are identical to those of Leon et al. (2010b) for non-rest conditions....
We present a new model for unsteady flow routing through dendritic and looped river networks
based on performance graphs. The model builds upon the application of Hydraulic
Performance Graph (HPG) to unsteady flow routing introduced by Gonzalez-Castro (2000)
and adopts the Volume Performance Graph (VPG) introduced by Hoy and Schmidt...
River flooding is a recurrent threat and its control and management continues to be a challenge. It has been recognized that effective flooding control requires a real-time strategy that combines optimization with a physically-based simulation model. Current real-time frameworks that combine simulation and optimization have two main drawbacks. The first...
