Abstract

The Kayan Watershed in Bulungan Regency is the largest river in North Kalimantan which has the potential for flooding in several irrigated points. Kayan River is a flood-prone area and prioritized to be handled immediately because there is already a smooth life for the community. Potentially need to know the great potential of flooding in the Kayan River. To find out the relationship between flood discharge and flood time, the Synthetic Unit Hydrograph calculation method is used. The aim is to determine the shape and results of peak discharge in Synthetic Unit Hydrograph Y (SUH). This study uses a debit calculation in the Kayan watershed using Snyder HSS a nd Nakayasu HSS. From the calculation results obtained Snyder SUH peak discharge of 118.0 m3/ sec at 73.85 hours, and Nakayasu SUH has a peak discharge of 109.35 m3 / sec at 54.09 hours.
布隆干摄政的Kayan流域是北加里曼丹最大的河流,在几个灌溉点有可能发生洪水。卡延河是一个易受洪水影响的地区,因为社区已经过上了平静的生活,所以必须立即优先处理。潜在的需要知道卡延河洪水的巨大潜力。为了找出洪流量与洪水时间的关系,采用了综合单元线计算方法。目的是确定合成单元水流图Y (SUH)中峰值流量的形状和结果。本研究使用Snyder HSS和Nakayasu HSS在Kayan流域进行借方计算。从计算结果中得出Snyder在73.85 h的峰值流量为118.0 m3/ sec, Nakayasu在54.09 h的峰值流量为109.35 m3/ sec。
