河砂的采挖活动改变了局部水流动力条件,破坏了天然情况下的泥沙冲淤平衡。为了有效掌握和控制采砂对局部河道的影响,以长江中游武汉河段神龙三厂二期吹填采砂项目为背景,研究了杨泗矶采砂对局部河道的影响。研究成果表明,杨泗矶采砂活... 河砂的采挖活动改变了局部水流动力条件,破坏了天然情况下的泥沙冲淤平衡。为了有效掌握和控制采砂对局部河道的影响,以长江中游武汉河段神龙三厂二期吹填采砂项目为背景,研究了杨泗矶采砂对局部河道的影响。研究成果表明,杨泗矶采砂活动对局部河床地形、局部流场和床沙级配将带来一定的影响,但经过一段时期的河床自我调整,这种变化将会得到一定程度的恢复,对采砂区局部河道河势造成的影响有限。 展开更多

Based on the screening analysis for the first time in Montenegro, water samples for the presence of emergent wereanalyzed. Results from the locality Vukovci, the lower course of the river Morale, have shown the presence of chemical components that indicate the presence of emergent in the water. Thus identification component is associated with the presence of fiziological groups of microorganisms at the site, which with its functional and significant role in many ways reduce environmental stress. 展开更多
