資料 Provenance 與來源分級系統 Data Provenance & Source Classification
台灣激流獨木舟實驗室建立了一套嚴格的資料來源分級系統，以確保資訊的透明度與可追溯性，明確區分官方標準、教練解讀、獨立工具及社群參考。
We implement a strict data provenance classification system to ensure information transparency. Clear boundaries are drawn between official standards, instructor interpretations, independent tools, and community references.
全站資訊分級架構 Site-Wide Information Classification Architecture
為避免使用者混淆，本站所有資料、手冊與工具均標記其來源級別（Source Type A 至 D）。使用者可隨時查驗各頁面資訊是來自 ACA 官方教材、政府公開 API，抑或是本站作者個人的教學解讀與自製計算模型。 To ensure complete transparency and prevent ambiguity, all content, manuals, and tools across this site are classified into four provenance tiers (Source Types A through D). Visitors can readily distinguish between official ACA standards, open government APIs, instructor interpretations, and proprietary analytical models.

數據方法論與侷限性 Data Limitations & Safety Caveats
本站所呈現的即時水位、定量降雨預報、與集水區逕流分析等數據，其運作基於以下模型與侷限，使用者在進行划行決策 (Trip Planning) 時應深刻理解： Live hydrology, QPF rainfall forecasts, and catchment runoff analytics operate under the following mathematical constraints that paddlers must comprehend during trip planning:
- 河川即時水位 (Wra API)： Real-Time River Levels (WRA API): 此數據反映特定監測站的點狀絕對水位與流量。溪流中游與峽谷段常因地形突變、局部暴雨而產生瞬時水躍，監測數據無法完全等同於現場特定灘段的安全狀態。 Reflects point measurements at monitoring stations. Canyon reaches frequently exhibit localized surges that may not match gauge readings.
- 定量降雨預報 (Cwa QPF)： Quantitative Precipitation Forecast (CWA QPF): 預報為 12 小時與 24 小時之網格估算值，無法精準預測局部的短延時強降雨（如午後雷陣雨）。 Provides 12- and 24-hour gridded averages; cannot precisely pinpoint localized short-duration convective storms.
- 集水區模擬 (accTW DTM)： Catchment Basin Simulation (accTW DTM): 地形模型採用 20m 高程點，未將人工水壩放水、農業引水渠道、地表滲透係數與植被截留納入計算，上游累積逕流面積僅為純地理高程推估。 Based on 20m terrain elevation; does not account for artificial dam releases, irrigation channels, or soil absorption factors.
關鍵安全警示：數據非絕對指引 Critical Safety Warning: Data Is Not An Absolute Guarantee
單一監測點的水位數值、預報雨量或模擬流量，絕不能直接等同於「絕對安全」或「絕對危險」。水域活動瞬息萬變，數據僅為提升處境警覺 (Situational Awareness) 與行前風險評估 (Risk Assessment) 之參考。划行者必須隨時觀察現場水色、水流流速、波形、障礙物，並以教練的現場專業判斷或主管機關之最新公告為最終決策依據。 Gauge heights, rainfall forecasts, or runoff simulations must never be equated with absolute safety. River environments change rapidly. Data serves only to enhance situational awareness and pre-trip risk evaluation. Paddlers must continually observe on-site water clarity, velocity, wave structures, and strainers, relying ultimately on qualified instructor judgment and official agency advisories.
