秀姑巒溪水系大斷面測量計畫(附光碟)

秀姑巒溪水系河川大斷面樁完成於民國64年，歷年來因大部份斷面樁已遺失或受破壞，本局分別於民國85年、95年及99年辦理「秀姑巒溪水系(主流及5大支流)大斷面測量」工作，民國101年辦理秀姑巒溪水系次支流之大斷面測量，以因應河川警戒水位檢討與訂定及建立斷面資料庫，做為該水系河床變遷、沖淤之探討。由於103及104年度將持續辦理「秀姑巒溪水系治理規劃檢討」計畫，並須依該檢討成果完成秀姑巒溪水系治理計畫修正，故需取得本水系最新的大斷面測量相關成果資料，以利後續相關水文水理計算及檢討，並做為日後河川管理及河堤防構造物之設計或安全評估之參考及依據。

The construction of embedding piles in cross-section at Hsiukuluan River system was completed in 1975. The surveillance area of Hsiukuluan River contained the mainstream and five tributary streams were proceeded in year 1996, 2006 and 2010 due to disappearance and damages most of the piles. In response to the warning of river water leveling stage and establish the cross-section database to explore the erosion of the river system and riverbed changes, the large cross-section measurement of Hsiukuluan tributary streams had been managed in year 2012. The planning of (Hsiukuluan River System Management Planning Review) will be continued in year 2014 and 2015, the future references of river management and the design of river embankment structures or the basis of safety assessment, the present water system is required to obtain the latest information on relevant outcomes of large cross-section measurement to facilitate subsequent treatment related to calculation and review of hydrology water management. The construction shall be completed in accordance with the system review outcome of governance plan of Hsiukuluan River streams data correction.
