In 1963, the area of the Nile Valley which was to become Lake Nasser had a relatively rich submerged and emergent flora (57 species, of which 6 were euhydrophytes) before the construction of the Aswan High Dam (AHD) (Boulos 1966). After the construction of AHD, Springuel & Murphy (1991) during 1980-1986 recorded 9 species of euhydrophytes, while Ali (1987) recorded 7 species only. Changes in aquatic vegetation may be due to changes in the water level regime and/or changes in the physico-chemical factors following waterbody regulation (Ali et al. 1995). The latter author discussed the effect of physico-chemical factors of both water and hydrosoil on the distribution of macrophyte vegetation in the River Nile in Upper Egypt (Lake Nasser, Aswan Reservoir and the Nile).","PeriodicalId":426163,"journal":{"name":"Enforcing Cybersecurity in Developing and Emerging Economies","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121784785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
