| Abstract | ||
| Some ecological characteristics are studied in the southern sector for the River AL- Masab AL-Aam at Nassirya city , for the period between November 2000 and October 2001 . Two locations were chosen . The first is situated at the enternece of the river to AL- Nassirya city. The second is at 7 km from the first one . The study was conducted to measure the seasonal changes of nutrientes, namely, nitrate , nitrite, phosphate, silicate and chlorophyll-a. Hydrogen concentration, water temperature and oxygen dissolved are also studied. This study shows monthly variations in value of nutrients and some ecological factors , associated within the two locationss . Nutrients values do not becom enough for growth . They show high values in some months . Statistical analysis shows no correlatios between silicate and , pH and nitrate and nitrite and chlorophyll-a at levels 1% and 5% between ecological characteristics as shown in the analytical table . | ||
