WP6: Field deployment and sensor performance, Dr. Indra S Sen


An important non-point pollution source to the Ganges River is small floodplain rivers. However these rivers are rarely studied since they are small in catchment area (-1000-10000) km and discharge (<100 m3/s). We will deploy or aqua monitoring platform on the Pandu River, which is right bank tributary of the Ganges River. Pandu originates near Kanpur in the state of Uttar Pradesh and flows for about 64 Km in a southeasterly direction before joining the Ganges. The source of Pandu River is a lake named Sabaid in Farrukhabaad district. The river runs around -242 Kilometers and meets the Ganga in Fatehpur district. The study area lies between latitude 26° 46′ N to 27° 42’N and longitude of 79° 07′ E to 80° 02′ E. The drainage area is approximately 1495 square kilometers and the average width of Pandu river is 15-16 meters. The rivers cover five different districts of Uttar Pradesh state that are Farrukhabaad, Kannauj, Auraiya, Kanpur Dehat, Kanpur Nagar and Fatehpur. lbis site was chosen for real time water monitoring or a proxy for a test bed because of the following reason:-

  1.  The river is only 242 Km long and having total catchment area of -1500 km, and therefore the environment is natural and better controlled. 
  2. PI Sen is already working on Pandu basin and we have baseline data for DO, pH, nutrients and many other water quality parameters.
  3. The site is only 30 km from lIT Kanpur campus, so accessibility is within an hour. Therefore we propose this site will be an ideal test-bed to deploy the aqua observatory under better-controlled natural
    environment.

Needless to say that all sensors will be calibrated in the Department of Earth Sciences using commercially available water quality probes For example, electrical conductivity, dissolved oxygen, salinity and temperature will be calibrated using the YSI water quality probe. The sensitivity of the CHANOS II for Cu and Cd measurements will be checked again geometrically determined known Cu and Cd solution of variable strength. The concentration of Cu and Cd will be measured using Quadruple Inductively Coupled Plasma Mass Spectrometer in the Department of Earth Sciences.
