Sable hydrogen, oxygen, carbon, and nitrogenisotopes (δDH2O, δ18OH2O, δ15NNO3, δ18O NO3, δ13CDIC), nutrients (PO4-, NO3-), and chlorophyllA of precipitation and river water samples are planned to analyze for their temporal andspatial variations during two-year period. Background of temporal variation in riverecosystem is to be established by seasonal sampling interval. In addition, post-event (typhoonor other natural hazard) sampling will be performed to study the hazard impaction on riverecosystem. The extent of impaction on river ecosystem due to human activity will be depictedafter comparing the isotope and nutrient characteristics among basins of Sijielanxi,Chichiawan, and Youshengxi. The specific objectives of this project include the following:1. Establish the δDH2O and δ18OH2O characteristics of precipitation and river water in studyarea for the background of identifying the hydrologic event.2. Establish the relationship between δ13CDIC and nutrients/chlorophyll A in river ecosystem.3. Identify the source and transformation of river NO3- by the analyses of δ15NNO3、δ18O NO3 ,and evaluate the relationship between river NO3- source and agriculture.4. Integrate the temporal and spatial results of isotope and nutrient analyses to study theimpact of natural hazard and human activity on river ecosystem

Using Isotopes to Study the Hydrological Relation of Reservoir Water with Its Neighboring Waters

本計畫在無預設前提立場下，欲藉由水文同位素技術鑑別翡翠水庫是否有滲漏到其周邊地區。本計畫選定台北盆地西南側與翡翠水庫間之相關水體包括溪水、泉水及地下水做為樣本，以月頻度方式分析他們的氫、氧同位素組成。在地質上有不少地質構造包括斷層、背斜及向斜橫切該地區，導致該區之岩層可能破碎而利於庫水滲出。經由本研究之同位素工作，本研究計畫預期可獲得下列之成果：1. 建立本計畫研究區帶各類水體一年期之氫氧同位素組成的時、空變異特徵。2. 研判翡翠水庫是否有庫水滲出。3. 釐清庫水本計畫區帶水體—台北盆地地下水三者間之水文關聯性。Without any personal prejudiced view, this project is to confirm whether water ofFeitsui Reservoir leak out to its adjacent region by hydrological isotopic technique. Waters,including creek water, spring water, and groundwater, in region located between the Reservoirand southwestern corner of Taipei Basin are monthly to analyze for their hydrogen andoxygen isotope compositions. Geologically, the strata in that region may be fragmented andsuitable for reservoir water to leak out because many structures including faults, anticlines,and synclines transect the region. Through the isotopic work of this study, the followingexpectative specific achievements of this project are obtained:1. Establish one-year period of temporal and spatial variations of hydrogen and oxygenisotope compositions of various waters in the study area.2. Diagnose whether the reservoir water leak out or not.3. Clear up the hydrological relations among the reservoir water, the studied water, and thegroundwater in Taipei Basin
