Abstract
The Diyala River, a significant tributary of the Tigris River, plays a vital role in the hydrology and ecology of the region. This study investigates the seasonal variations in physicochemical and microbial parameters of the Diyala River after its confluence with the Tigris River. Water samples were collected quarterly over one year to assess parameters including temperature, pH, dissolved oxygen (DO), turbidity, electrical conductivity (EC), total dissolved solids (TDS), nutrients (nitrate, phosphate), and microbial indicators such as total coliforms and fecal coliforms. Results revealed marked seasonal fluctuations, with higher nutrient concentrations and microbial loads during the summer and lower values in winter, correlating with changes in water flow, temperature, and anthropogenic activities. The physicochemical parameters mostly complied with international water quality standards, but microbial contamination occasionally exceeded safe limits, indicating potential health risks. The findings underscore the need for continuous monitoring and effective management strategies to safeguard water quality in the Diyala-Tigris river system, especially considering increasing human and agricultural pressures.
