資料 Provenance 與來源分級系統 Data Provenance & Source Classification

台灣激流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:

  • 河川即時水位與放流量 (WRA API): Real-Time River Levels & Discharge (WRA API): 此數據反映特定測站點狀之物理水位與水庫放流量,是驗證降雨實際水文反應的重要依據。但測站若距離航行河段較遠,或下游存在支流匯入、峽谷地形突變,測站數據無法直接等同於特定險灘之局部流態。 Reflects in-situ gauge stages and reservoir releases. However, distance from target runs, unmonitored tributaries, and canyon constrictions mean gauge readings cannot replace physical on-site river scouting.
  • 定量降雨估計 (NCDR / CWA QPE): Quantitative Precipitation Estimation (QPE): QPE 為將雨量站點觀測結合雷達回波演算法產生之格點化面降雨估計。純雨量站空間內插受限於測站密度,在缺乏測站深山可能無法反映局部強降雨空間差異;雷達與雙偏極化整合能提供空間面分布資訊,但在極高山深谷仍受波束遮蔽 (Beam Blockage)、降水粒子水平輸送等物理反演誤差影響。 QPE produces gridded areal estimates from gauge and radar fusion. Gauge interpolation has blindspots in ungauged alpine valleys, while radar estimates carry uncertainties from beam blockage, ground clutter, and hydrometeor drift.
  • 定量降雨預報 (CWA / NCDR QPF): Quantitative Precipitation Forecast (QPF): QPF 整合大氣數值模式、系集預報與 AI 降尺度產品,提供未來尚未發生之降雨情境與趨勢(非確定事件)。預報時間越遠不確定性越高,且數值網格平滑化對於台灣微尺度「地形強迫抬升雨」與午後熱對流之精確落點存在時空變異。 QPF provides probabilistic forecast scenarios from numerical weather models and AI downscaling. Uncertainty increases with lead time, and grid-smoothing limits precise localization of micro-scale orographic and convective cells.
  • 前期累積降雨 (Antecedent Moisture Proxy): Antecedent Cumulative Rain (Moisture Proxy): 72 小時前期累積降雨為判斷集水區前期濕潤程度與潛在逕流反應的參考指標,不可直接等同於土壤水分飽和度 (Soil Saturation)。實際土壤含水量與產流速度仍受土層厚度、地質、坡度、植被覆蓋與前期長期水文條件影響。 72h cumulative rainfall serves as a proxy for antecedent catchment wetness rather than direct soil saturation. Hydrological response is modulated by soil depth, lithology, slope, and canopy interception.
  • 集水區地形模擬 (accTW DTM): Catchment Basin Simulation (accTW DTM): 地形模型採用 20m 高程數據與 D8 流向演算法,未將人工攔水壩、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 digital elevation and D8 routing; does not account for dams, irrigation diversions, soil infiltration, or vegetation interception.

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.
