ABSTRACT
This study determined the natural and environmental characteristics of Baher Al-Najaf Depression
(BAND) in Iraq and their effect on nutrients of
Typha domingensis as responses to environmental
stresses in 4 sites. Samples were collected monthly (February 2015 to January 2016). The
environmental factors of water and sediment were included: Temperature, Electrical Conductivity
(EC), Salinity, pH, Total Dissolved Solids (TDS), Turbidity, Total Suspended Solids (TSS), Dissolved
Oxygen (DO), Total Hardness (TH), Total Nitrogen (TN), Total Phosphorus (TP), Sulfate (SO
42-),
Potassium (K
+1), Chloride (Cl-1), Sodium (Na1+), and Total Organic Carbon (TOC). The highest
values of the environmental factors were found to be at autumn and summer whereas the lowest
values were at winter and spring. Environmental factors were ordered significantly as follows: S2>
S3> S4> S1. The studied factors of climate were air temperature, relative humidity, the intensity of
solar radiation, precipitation rate and evaporation rate. This study has shown that climatic factors
effected on water resources and salinity level in BAND
. Ionic contents (Na+ and Cl) were increased
significantly whereas K
+, TP, and TN were decreased with increasing levels of environmental
stresses at each site along with the season. In general, the levels of nutrients (N and P) were

ordered as follows: water <sediments < plants. This means that
Typha domingensis have the ability
the accumulation of nutrients.
