Comparing the computed values with those of 50 tidal observatories , we find that the computational precision with fine grids and moving boundary are generally higher than that with wide grids or fixed boundary 沿岸50個潮位站計算與實測值的比較表明,加入動邊界以后的小區(qū)域細網(wǎng)格計算較之粗網(wǎng)格以及未加動邊界以前的情況,精度都有普遍提高。
Based on the research of intertidal flat topography measure at home and abroad , this article avoids some problems troublesome , such as the dependence of the station of tide gauging , precise match of images and so on . first , we monitor soil water content of intertidal flat through building correlation model between soil water content of intertidal flat and landsat tm data , then we analyse the correlation between soil water content and topography of intertidal flat , last , we extract topography of intertidal flat combining with gis 本文在總結(jié)國內(nèi)外潮灘地形測量研究的基礎(chǔ)上,避開對潮位站的依賴和影像精配準(zhǔn)問題,以江蘇大豐港堤附近淤泥質(zhì)潮灘為研究區(qū)域,通過遙感方法建立潮灘土壤水分與tu光譜值的定量數(shù)學(xué)模型,提取潮灘土壤含水量信息,然后通過潮灘土壤水分與地形的定量關(guān)系,結(jié)合gis技術(shù)反演潮灘地形。
Based on the materials observed many years at the tidal observatories and the ocean current data measured in the coastal zone and islands in zhejiang province , the characteristics of tides , tidal currents and residual currents are analyzed and processed by harmonic analysis and statistical methods systematically . such research results are compared with those from the numerical simulation to validate the effectiveness of the latter 本文以多年來沿岸各潮位站觀測資料以及海岸帶和海島調(diào)查的實測海流資料為依據(jù),用調(diào)和分析和統(tǒng)計的方法對浙江近海的實測潮汐、潮流和余流特征進行了系統(tǒng)全面的整理和研究,這些實測數(shù)據(jù)將作為檢驗數(shù)值模擬是否成功的依據(jù)。
