Most water pollutants are eventually carried by rivers into the oceans. In some areas of the world the influence can be traced hundred miles from the mouth by studies using hydrology transport models. Advanced computer models such as SWMM or the DSSAM Model have been used in many locations worldwide to examine the fate of pollutants in aquatic systems. Indicator filter feeding species such as copepods have also been used to study pollutant fates in the New York Bight‚ for example. The highest toxin

Q1 Q1 A) The sudden closure of valve at the end of a pipeline cause sudden change in the water velocity which in turn creates a phenomenon called water hammer. The water in motion is forced to stop or change direction suddenly (momentum change) and a pressure wave propagates in the pipe. It ’s also called hydraulic shock. The effect of this event can be effectively multiplied many times by the geometry of a piping system if the pressure wave is allowed to reflect‚ or bounce‚ back and forth

bronze vessel from the Shang Dynasty‚ then I realized it looks a lot more like Archer Jing’s ritual bronze than any vessels we looked at. And sure enough‚ it was a ritual bronze with inscriptions from the Zhou Dynasty. So it was actually a ritual water basin called jian from the Eastern Zhou Dynasty made from bronze. I thought it was a good size with maybe two feet or more in diameter and maybe a foot and a half to two feet in height. The outside was very decorative all around and there were four

Since all natural waterways contain bacteria and nutrients‚ almost any waste compounds introduced into such waterways will initiate biochemical reactions (such as shown above). Those biochemical reactions create what is measured in the laboratory as the Biochemical oxygen demand (BOD). Such chemicals are also liable to be broken down using strong oxidizing agents and these chemical reactions create what is measured in the laboratory as the Chemical oxygen demand (COD). Both the BOD and COD tests
