Due to rapid development nowadays, the natural storage of rainfall water is affected as water cannot infiltrate into the soil and thus, the water will remain as surface water which can lead to flooding. Detention basin had been applied by most of the countries in the world to encounter this problem and many researches had been done in this field. The objective of this research is to study the stage and discharge relationship of the detention pond. The study had been done using physical model of detention pond in the laboratory which has been scaled down 100 times from the real size. The experiment was repeated by manipulating the number of valve rotation to get different discharge of inflow. For every rotation, the stage and discharge was calculated and relationship was developed. From the experiment that had been done, it is proved that the stage will increase with increased discharge. Besides, the storage also increased as the stage increased. This experiment however can be further studied and corrected using the physical model that having the same characteristic and condition as the real detention pond so that the result obtained more accurate and precise.
