Radar Hydrology: New Z/R Relationships for Quantitative Precipitation Estimation in Klang River Basin, Malaysia

Suzana Ramli and Wardah Tahir

Abstract—The use of Quantitative Precipitation Estimation (QPE) in radar-rainfall measurement for hydrological purposes is significantly important. For more than 50 years, radars have been deployed to monitor and estimate the precipitation routine in several countries. However in Malaysia, radar application in QPE is still new and needs to be explored. This paper focuses on the Z/R derivation work of radar rainfall estimation. The work developed new Z/R relationships for the Klang River in the Selangor area for three different classes of rain events, namely low (<10mm/hr), moderate (>10mm/hr, <30mm/hr) and heavy (>30mm/hr). Looking at the high potential of Doppler radar in QPE, the newly formulated Z/R equations will be useful in improving the measurement of rainfall for any hydrological application, especially for flood forecasting.

Index Terms—Radar, Quantitative Precipitation Estimation, Z/R development, flood forecasting.
