Study of Open Drainage System With The Help of Remote Sensing Technique : Gomti River Case Study
This paper presents the remote sensing technique for the study of open drainage system and its effect on Gomti river in Lucknow area.Gomti river originates from MadhoganjTanda village in Pilibhit district, U.P. It passes through the district of Shahjahanpur, Kheri, Hardoi, Sitapur, Lucknow, Barabanki, Sultanpur, Jaunpur and ultimately merges in the Ganga. The world is facing problems with a wide variety of pollutants both inorganic and organic in nature. Healthy soil, clean water and air are the soul of life. Often soil, water and air are no longer clean and pure, but pose human health risks. Gomti receives huge quantities of untreated sewage, agricultural runoff, brings lot of pesticides, fertilizer, street washouts bringing oil, asphalt, sediment and many types of heavy metals. From industrial effluents to domestic discharge, the river becomes more of a flowing dumping yard. The physicochemical parameters in water of river Gomti were assessed to know about the water quality in its catchment area. Parameters like Temperature, Total suspended solids (TSS), Total dissolved solid (TDS), pH, Hardness, Dissolved oxygen (DO), Nitrate, Nitrite, Chlorine, Total Coliforms and some Heavy metals were determined. Changes in water quality of River Gomti due to variations in quantity of parameters were found. Heavy metals mainly Iron, Cadmium, Copper and Arsenic were noticed.
