Evaluation of BOD and DO for Diyala River by Using Stream Water Quality Model
G. A. AL-Dulaimi
Abstract—This paper was studied the biochemical parameter
(BOD5) and (DO) for Diyala River (Iraq) which regard
significant tributary for the Tigris River. Water samples have
been collected from Diyala River along different points between
Baquba to Al-Zafarania and were analyzed for various water
quality parameters during low flow season (November). The
study involves application of stream water quality
model QUAL2K model to simulate and predict the dissolved
oxygen (DO) and biochemical oxygen demand (BOD5) profiles
for Diyala River in a stretch of 251 kilometer. Model output
showed that DO in the entire river was within limit of not less
than 4 mg/L. For Carbonaceous Biochemical Oxygen Demand
CBOD, the entire river may be divided into three main reaches;
first one is extended from Kalar City (0 km) to Jalawla (46 km)
and have CBOD concentration of 2 mg/L , the second reach has
CBOD range (2–4) mg/L in which begins from Sadiyah city and
extend to near Buhriz city city(168km), the third reach extends
from Khan Bani Saad city to Al-Zafaraniah (251km) in the
south east of Baghdad city confluence point with Tigris River
which has CBOD concentrations of more than 5mg/L.
Index Terms—BOD, COD, Diyala river.
