Water supply capability has been significantly reduced as water demand has been increased due to changes of the world's weather, causing the increase of drought frequency, and urbanization. In terms o...
Cyanobacterial blooms have become a worldwide concern due to the production of toxins harmful to humans and animals. In Brazil and worldwide, microcystins are the most frequently found cyanotoxin in w...
Mega cities in developing countries are mostly dependent on external funding for improving the civic infrastructures like water supply. International and sometimes national agencies stipulate financia...
For more than a decade it has been known that shallow tube wells in Bangladesh are frequently contaminated with arsenic concentrations at a level that is harmful to human health. By now it is clear th...
运用瞬态水力学理论和特征线方法,结合某实际工程,对联合采用空气阀、泄压阀和二阶段缓闭蝶阀进行水锤防护的长距离有压输水管道系统的事故停泵水力过渡过程进行了计算和分析,得到管线沿程的水锤压力包络线和空化体积曲线,以及典型断面的压力时程线。计算结果表明,采用两阶段缓闭蝶阀、泄压阀和空气阀进行水锤安全防护是十分必要的,有利于抑制正水锤压力的继续升高和阻止负水锤压力的持续降低,防止断流弥合水锤的发生。但从计...
