Flood Water DO Determination by new DO-Sag Equation
Ravindra Sharma,  Dr. M.K. Verma,  Dr. Meena Murmu,  Dr. P.K. Ghosh
Flood water DO determination by application of Streeter Phelps equation is a difficult task, because river velocity and depth during rainy season cannot be determined by conventional surveying methods. During Rainy Season quality of river water deteriorates due to occasional flood. The author is carrying out research investigations on Shivnath River water to assess its quality using Streeter Phelps equation. Therefore DO variation is being monitored over a period of one year i.e. Jan. 2017 to Dec. 2017. Past experience shows that during July-August, extreme fluvial flood event takes place in Shivnath River due to excessive rain fall and discharge of surplus water from Tandula dam. The results showed that water quality is very dynamic during flooding, especially at the beginning of the event. In addition, it was observed that the pathogen and contaminant levels in the flood water are almost as high as in sewers. The finding shows that population exposed to flood water runs a health risk that is nearly equal to that of being in contact with sewer water. As a result, the people of Durg-Bhilai Township not only face physical risk due to flooding, but are also exposed to health risks. Pollution of water bodies, depletion of ground water, lack of drinking water and improper sewage disposal are some of the water related problems encountered due to rapid growth of an industrial township. However, studies of flood water quality dynamics are not often reported in literature, probably due to difficult conditions for sampling during flood events. Therefore authors have extended DO Model study to find out whether Streeter Phelps equation can be applied to assess flood water quality.
A unique design of flood water harvesting system is prepared to show its importance as a social welfare project to be implemented on all rivers in the country to protect road side bridges from flood water damages besides managing smooth movement of traffic without and jam.
