Optimisation of hydrometric network using entropy method

摘要

Establishment and maintenance of a hydrometric network in any geographical region is required for planning, design and management of water resources. Setting up and maintaining a hydrometric network is an evolutionary process, wherein a network is established early in the development of the geographical area; and the network reviewed and upgraded periodically to arrive at the optimum network. This paper presents the methodology for optimisation of a hydrometric network using entropy method. The technique, involving computation of marginal and conditional entropy measures, is applied to the Upper Bhima basin up to Ujjani reservoir for illustrative purposes; and results presented. The derived optimum hydrometric network for the basin is evaluated based on WMO guidelines for minimum density of hydrometric network.
