CRDEMO: Combined regionalization and dual entropy-multiobjective optimization for hydrometric network design

Abstract: [1] Establishing an adequate hydrometric network to provide accurate and reliable continuous flow information for various users remains a major challenge. This includes the design of new networks or the evaluation of existing networks. This study proposes a combined regionalization and dual entropy-multiobjective optimization (CRDEMO) method for determining minimum network that meets the World Meteorology Organization (WMO) standards, which is considered herein an optimal minimum network. A regionalization app… Show more

“…The use of hydrodynamic model enabled to determine the critical monitoring locations in the main stream and its tributaries. On the other hand, Samuel et al [49] combined regionalization techniques with entropy calculation in order to estimate the discharge at candidate locations. They compared the performance of various regionalization methods including not only a conceptual hydrologic model, but also spatial proximity, physical similarity and their combinations with drainage area ratio.…”

“…Unfortunately, the monitoring of soil moisture is very sparse compared to its spatial variability. To design an optimum network for monitoring soil moisture in the Great Lakes Basin, Kornelsen and Coulibaly [36] proposed using data from the Soil Moisture and Ocean Salinity (SMOS) satellite [76] to design a soil moisture monitoring network using the DEMO algorithm of Samuel et al [49]. Grid cells were selected to add monitoring stations that optimally maximized joint entropy while minimizing total correlation using only the satellite data.…”

“…In order to handle uncertainties in design and operational problems, several methodologies such as fuzzy approach (Fu and Kapelan, 2011), approximating techniques (Afshar et al, 2009) and entropy-based methods (Samuel et al, 2013) have been developed. Among them, Monte Carlo Simulation (MCS), which is also used in this study, is known as the most flexible and reliable method (Shrestha, 2009).…”

“…Entropy theory [20] provides a nonparametric measure of the uncertainty of an outcome of a discrete random process and can be used to determine the information content of a particular set of data [19], [20]. The dual-entropy multiobjective optimization (DEMO) system was developed based on the entropy concept for the design of optimal hydrometric networks [21]. DEMO implements the epsilon-dominance hierarchical Bayesian optimization algorithm (ε-hBOA) [22] to find a set of monitoring sites that maximizes the amount of information defined by the joint entropy, while minimizing the shared information content [21].…”

In order to determine the information content in a potential network, DEMO requires estimates or observations of the geophysical variable for which the network is to be designed at each potential monitoring location.…”
