Rain gauge optimization network in Johor

Abstract

Rainfall data are input in numerous water resources management tasks such as water budget analysis and assessment, flood analysis and forecasting, stream flow estimation, and design of hydraulic structures. Are liable and optimal rain gauge network can provide accurate and precise rainfall data that are crucial for effective and efficient design of hydraulic structures for flood control. This will help researchers to minimize the hydrological and economic risk and errors involved in any related water resources projects. A well-designed rain gauge network thus should contain a sufficient number of rain gauges, which reflect the spatial and temporal variability of rainfall in a catchment. Thus, identification and selection of the optimal rain gauge network configuration having optimal number and locations of rain gauge stations is the main objective of the network design. Hence, the optimal rain gauge network should contain the number and locations of rain gauge stations in such a way that it can yield optimum rainfall information with minimum uncertainty and cost.
