The experimental watershed with area of 3.33 ha, which was located in the southwestern side of comprehensive district of soil and water conservation of National Pingtung University of Science and Technology, Taiwan. The 0.8 m top width of levee had constructed in contraction zone close to midstream of watershed, and could created the space of storage runoff with width, length and height in 6m, 8m and 2m. This study was primarily aimed at the micro-meteorological variation after creating levee to storage runoff in a small watershed. All the observation included as: air temperature, relative humidity, and net radiation had measured by a meteorological station from October, 2014 to August, 2015. The result had shown the storage runoff could result variation of air temperature and relative humidity. The difference of air temperature b
