The dynamic of nutrient cycling is a critical factor in riparian regions. It is essential to understand the behaviour of riparian areas in the maintenance and management river ecosystem. Sediment load, nutrients, and pathogens are transported to water bodies through land drainage and riverside flow. The classification of environmental agencies was poor for them. In this study, a qualitative investigation was implemented to determine the relationship between these practices and variations in nutrient retention for several types of riverbank soil. Also, the riverbank soils were including soil covered by wild reed plants. All the field works were along the Euphrates River in three locations. Moreover, study the variation in the content of vegetation riverbank soils from nitrogen, organic matter (OM), potassium (K), phosphorus (P), and PH. The results presented that riverbanks consider important locations for nutrient retention. Whilst agricultural activities have minimized the content of soil of OM (30%), N (49%), and K (3%), in subsurface soil but not so great lowering in surface layers. In contrast, management practices and human activities such as burning caused an apparent increase of OM (4%), N (77%), and a clear reduction in P (12%) content at both surface and subsurface layers of soil. Under all circumstances, riverbank soils showed a relative increase of nutrients at wet toe-slopes. Furthermore, it is noted that riparian vegetation and aquatic plants played a significant role by causing critical changes in riparian sides or even contrary effects on riverbank management practices and destruction of natural soil nutrient conditions. Thus, it should be carefully considered when evaluating the ecological impacts of riparian disturbances.

In spite of hydrology and geology disciplines` are relatively well known in Iraqi management strategy, unlike soil and its distribution system. Thus, describing strong indicator for evaluating water pathways, minerals, and materials in different soils is necessary to reduce the associated risks. However, the aim of this research is identified the change in soil behavior by observation, and interpretation the facts for effective indication mode. This mode is evaluated some features and properties in (soil- water) horizons from a focus on land use change in (e.g built up and rural) areas compared with riparian sites in middle region of Iraq. The evaluation is included field sampling by using `Drill auger` instrument and laboratory tests for analysis. The results areinterpreted as onset of soil impairment indices under changing in human activities, agricultural practices, climate change and effect of water movement. The elements are considerably bound with silt and clay particles which ultimately minimize leaching ability to lower layers in each horizon. The free access of water and air allows rapid oxidation of elements and caused materials corrosion and the output of leaches which can contaminate ground water and surface water. Besides, some elements are negatively correlated with concentrations of calcium carbonate. The content of sulfur compound in assorted land uses is uneven and increased with increase water content or agitating time. Also, the sulfur oxidation even if small proportion in fill material lead to the output of polluted drainage water and attack construction material when structural backfill and for bulk fill. Thus, its significant to consider these features for ameliorative engineering behavior.
