operational monitoring of the groundwater as well as for the surface water and are
also responsible for the water quality determination and was found that 8 monitored
ground water bodies, 3 surface reservoirs, 12 surface water bodies that are artificial
as well as heavily modified and on the other side 14 surface water bodies found in
natural status [23].
Figure 6 shows 7 models of the surface water with their versions and characteristics. The Streeter-Phelps provides the first S-P model in 1925. Mainly the S-P
model focuses on the oxygen balance as well as the one-order decline of the
demand for biological oxygen and is a one-dimensional stable-state model. USEPA
