ENTROPY BASED ASSESSMENT OF HYDROMETRIC NETWORK USING NORMAL AND LOG-NORMAL DISTRIBUTIONS

. ENTROPY BASED ASSESSMENT OF HYDROMETRIC NETWORK USING NORMAL AND LOG-NORMAL DISTRIBUTIONS, 1 (1): 33-42 (May 2014)

Abstract

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 adopted in assessing the hydrometric network using entropy theory adopting normal and log-normal probability distributions. The technique, involving computation of marginal and conditional entropy values, 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
