Pucak Terate Bang temple is one of main  in Bali located in Banjar Catu, Candikuning Village, Baturiti District, Tabanan Regency, precisely  in Eka Karya Bedugul Botanical Garden area. This temple lies at an altitude of about 700 above sea level  with the surrounding conditions still a natural forest. This temple is located under Lake Buyan and Lake Tamblingan which became the tip of  Sungi river  which eventually leads to  Penet river  in Cemagi Beach Badung regency. With the very high  intensity  at the end of 2016 until early 2017 precisely in January 2017 has caused the occurrence terrible floods and landslide in the area of ​​Pucak Terate Bang and surrounding areas. These floods and landslides have caused severe damage to the temple  and other areas of the Eka Karya Botanical Garden and other areas through which the upstream  of  Sungi river  flows  at the downstream.

The method of this research is descriptive quantitative and qualitative by conducting observation and direct measurement in the field done by hydrological analysis and hydraulic analysis and river capacity to get the formulation of flood handling required in accordance with Sungi river  upstream characteristic in Terate Bang temple  and surrounding area.

The results of the design rain analysis are as follows: R2 = 85.46 mm, R5 = 94.63 mm, R10 = 99.25 mm, R20 = 102.36 mm and R25 = 103.80 mm. Flood calculations show Q2 = 16.55 m3 / dt, Q5 = 18.32 m3 / dt, Q10 = 19.99 m3 / s, Q20 = 19.74 m3 / s and Q25 = 20.02 m3 / s. If this is related to the current channel capacity of Q25 of 20.02 m3 / st then the flood discharge is much larger with the capacity that can be accommodated by the channel. In addition to the small channel capacity another cause of flooding is the existence of a building built on the river channel. The recommended solution of this research is the making of 3 plunge buildings with an average width of 3 m with varied heights ranging from 2-3 m, channels with pre cast material in several variations, making a bridge with box culvert model with dimensions 2 x 2 m and making three variations of retaining wall
