簡要介紹
1) 飽和-非飽和流與水氣二相流參數模型研究
非飽和滲透系數是含水層中飽和-非飽和流與水氣二相流的關鍵參數,。已有的非飽和滲透系數模型,,對于飽和-非飽和流低估了實測值;對于水氣二相流則高估了實測值,。不準確的非飽和滲透系數可能是制約數值模擬精度的瓶頸,。匡星星團隊改進了van Genuchten模型,,新模型改進了非飽和滲透系數對實測數據的吻合程度,。成果發(fā)表在國際土壤學重要期刊《European Journal of Soil Science》??镄切菆F隊推導出了一個新的非飽和空氣滲透系數模型,,提高了計算值與實測值之間的吻合程度。成果發(fā)表在國際水文水資源頂級期刊《Water Resources Research》,。
滲透系數是控制地殼中流體流動的最重要的參數,。地殼的滲透系數隨深度衰減。已有的描述這種衰減關系的模型要么在地表數值趨于無窮大,,要么隨深度衰減得太快,。匡星星團隊提出了一個新的模型,,該模型克服了現有模型的缺點,,可用于描述整個地殼的滲透系數隨深度的變化,。成果發(fā)表在國際地球科學綜合重要期刊《Geophysical Research Letters》,。
2) 飽和-非飽和流與水氣二相流試驗與數值模擬
試驗研究和數值模擬是研究地下水資源、地下水水質的不可或缺的重要手段,。上覆低滲透性地層的二元結構潛水含水層在自然界普遍存在,。研究這種二元結構潛水含水層抽水試驗引起的水、氣流動機理以及空氣流對抽水試驗的影響變得非常重要,??镄切菆F隊通過室內試驗研究與數值模擬,從機理上闡明了這種二元結構潛水含水層抽水試驗引起的水氣二相流機理,,包括雙層砂柱排水試驗與模擬,、雙層砂箱抽水試驗與模擬、以及雙層潛水含水層抽水試驗數值模擬,。相關成果發(fā)表在國際水資源著名期刊上,,包括《Water Resources Research》,、《Hydrological Processes》、以及《Hydrogeology Journal》,。
3) 多孔介質溶質運移數值模擬
三角洲地區(qū)的含水層系統(tǒng)往往呈現出多層的特征,,含水層與弱透水層交替出現。由于三角洲地區(qū)在經濟社會中的重要性,,三角洲地層中的溶質運移過程是一個受到廣泛關注的問題,。基于對二元結構潛水含水層的研究,,建立了一個考慮連續(xù)沉積過程的溶質運移模型,,并將該模型運用于模擬珠江三角洲含水層-弱透水層系統(tǒng)中氯離子和氫氧同位素的運移機理。相關成果發(fā)表在國際水資源重要期刊《Hydrological Processes》和《Hydrogeology Journal》,。
4) 地下水對氣候變化的響應
由于全球氣候變暖,,高海拔地區(qū)的冰川正在后退,凍土正在退化,。作為水循環(huán)中至關重要的一環(huán),,地下水也正在受到氣候變暖的影響。由于高海拔地區(qū)往往是大江大河的源頭地區(qū),,因此,,研究高海拔地區(qū)氣候變暖對地下水流系統(tǒng)的影響,具有重要的意義,??镄切菆F隊正在研究全球氣候變暖引起的青藏高原冰雪融化對地下水流系統(tǒng)的影響。由于全球氣候變暖,,青藏高原上的冰雪和冰川正在融化,。這種冰雪的融化可能對地下水流系統(tǒng)產生重大的影響。相關成果發(fā)表在該領域重要期刊《Journal of Geophysical Research: Atmospheres》,。
