multiple research fields including transportation infrastructure, nuclear waste disposal, municipal solid waste landfill design, remediation of mine waste/contaminated soils, and sustainable geotechnical practices.Dr. Farshad Amini is Professor and Chair of the Department of Civil & Environmental En

gineering, Industrial Systems & Technology at Jackson State University, where he initiated a new Civil Engineering Department in 2000. He has led the development of new ABET-accredited undergraduate program, as well as graduate programs (M.S. and Ph.D.) in Civil. Environmental, Coastal and Geologica

l Engineering. The enrollment increased at a rate of 15% per year during the last ten years. He also led the establishment of new world class civil engineering teaching and research laboratories, as well as many new research projects. He has served as the co-director of the Electron Microscope Labor

atory, a multi-user core college laboratory facility, and also manages the Environmental Scanning Electron Microscope, obtained through his NSF-MRI grant. He received his BS and MS from the University of Kansas, and Ph.D. from the University of Maryland, College Park. Professor Amini is well known f

or his research in levee strengthening during hurricanes, through full scale testing, numerical methods, and slope stability. This has resulted in more than 40 publications, with many in top engineering journals. In addition, professor Amini applies his expertise in various areas of geotechnical and

earthquake engineering, soil and structural dynamics, levee protection, and infrastructure. He has been principal investigator or co-principal investigator of more than sixty grants including forty major research grants with eight grants from the National Science Foundation (NSF), four from the Arm

y Research Office (ARO), two from the Department of Homeland Security (DHS), one from the Air Force Office of Scientific Research, (AFOSR), three from the U.S. Geological Survey (USGS), six from the Mississippi Department of Transportation (MDOT), eight from the DOD, one from the Navy, and several o

ther grants from other agencies. He has published more than one hundred sixty research papers. He served on the Editorial Board of the Journal of Geotechnical & Geoenvironmental Engineering, ASCE, the most prestigious journal in his field from 1990 through 2002. His accolades include the Faculty Pro

ductivity Award in 2006 and the University Outstanding Researcher of the Year Award in 1994, amongst his many awards. He has served as a senior Program Evaluator for the Accreditation Board for Engineering and Technology, Accreditation Engineering Commission (ABET-EAC). Dr. Amini is a Fellow of the

濁水溪流域水文量與輸砂量之趨勢研究

為了解決USGS的問題，作者黃震宇 這樣論述：

本研究以濁水溪流域之桶頭(2)、內茅埔、延平橋、彰雲橋、玉峰橋、水里橋、溪洲大橋、寶石橋及龍門橋水位流量站，以及集集(2)、神龍橋、桶頭(2)、西螺(2)、翠峰、內茅埔雨量站，其觀測水文量資料(含觀測流量、懸浮載輸砂量資料與觀測雨量資料)，採用5％顯著水準 (α=5％) 執行觀測流量、雨量之Mann-Kendall(M-K)趨勢檢定與分析。本研究除了以距平圖協助判斷流量、雨量之趨勢變化情形外，另建立流量與輸砂量之關係曲線圖及經驗公式，並以九二一大地震前後1999年為時間分點觀察輸砂量變異分析。本研究中選用之日平均流量、年逕流量、年最大瞬時流量、年最大日平均流量、年最小日平均流量之M-K趨勢分

析結果顯示寶石橋站(2004-2020)之年最大瞬時流量呈顯著向下趨勢，而水里站(1994-2020)與寶石橋站(2004-2020)之年最小日平均流量則呈顯著上升趨勢，其它各水位流量站之流量資料則無顯著趨勢(no trend)。本研究選用之年降雨量、年一日最大降雨、年二日最大降雨、年三日最大降雨量之M-K趨勢分析結果，顯示只有桶頭(2)站(1941-2020)在年一日最大降雨量、年二日最大降雨量、年三日最大降雨量呈顯著上升趨勢；其它各雨量站之雨量資料均無顯著趨勢。本研究中顯示濁水溪流域各觀測站(桶頭(2)站、彰雲橋站、內茅埔站與玉峰橋站)之日平均流量與懸浮載輸砂量關係為良好之率定曲線關係式。

以九二一大地震前後分別繪製之率定曲線式結果顯示，各觀測站在九二一大地震前之期間的率定曲線相對較為陡峭。而各觀測站在九二一大地震後的河道懸浮載輸砂量由低流量開始即超過九二一大地震前的河道懸浮載輸砂量，顯示九二一大地震對濁水溪流域土砂生產量有明顯的增加現象。關鍵字：趨勢分析、顯著趨勢、率定曲線、假設檢定、MK、Mann-Kendall。
