Such a relationship can be used to make an accurate estimation of the apparent velocity and further assess the egg survival rate. The proposed quantitative model may well serve as an effective tool for planning of habitat restoration project.application/pdf128079 bytesapplication/pdfzh-TW國立臺灣大學生物環境系統工程學系暨研究所鮭鱒魚產卵礫石河床河床形貌壓力差孔隙水流速度Salmonidsspawning gravelsbedformpressure dropapparent velocityreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/10686/1/892211E002142.pdf
