Abstract

Quality of rainfall information for a given watershed or region is primary information needed for the sustainable designing and operation of water resources systems. For an optimal rainfall network design, they should be reviewed periodically based on the information needs and future water resources development plans. This study evaluated regional values of rain gages in great Karoun basin located in Khozestan, Iran, using the discrete entropy. Discrete entropy can overcome limits of data normality assumption in past research and applications for hydrological variables. To determine the regional value of each station within a region, several information parameters such as marginal entropy, joint entropy and trans information index between stations, were calculated to identify essential rain gauge and critical area. Sensitivity analysis to number of DISCRETE INTERVALS showed that the entropy is sensitive to changes, but the ranks based on entropy indices appear to be less sensitive. Finally, results confirm that the entropy is useful to characterize the essential and excess station in the region and density of 31 rain gauge network is optimal and other rain gauge can be removed from monitoring network.
