Urban air quality evaluation over Kut city using field survey and Geomatic techniques

As a result of high levels of food consumption and general economic expansion, there has been a concomitant increase in the amount of organic waste produced. This increase was the result of significant advances in agricultural production techniques. Good waste management is one of the most effective ways to restore levels of depleted organic substances in the soil by re-entering carbon into the system in the form of organic inputs. Fertilization is a means of treating wastes that have increased their popularity over the years. In this research, two experiments were conducted. The first is C/N 50% in winter and the second is an unspecified C/N study in summer of the characteristics affecting the application after mixing 10%, 20%, 30% and 40% fertilizer with soil contaminated with organic pollutants from Aldora refinery in Baghdad. These characteristics are (Specific gravity, Falling Head permeability, TDs, SO3, Unconfined compressive strength). It has been found that there is an inverse relationship between the Specific gravity and the compost percentage. The permeability and Unconfined compressive strength are increasing with increased compost, and salts and SO3 depend on their concentration in both contaminated soil and fertilizer. From these results, it is possible to take advantage of this fertilizer produced to improve some soil properties, especially silty clay soil, not only in the field of agriculture, improving the soil and strengthening it for plant growth.

This paper studies the impact of the stormwater network outfall of the Al-Rabee Quarter on the Tigris River. Residents of the district use the storm network for contacts of illegal sewage. Household wastewater is discharged through the storm network directly into the river without treatment, which affects the water quality. Storm network model was developed and use a dynamic wave approach in routing hydraulic flow. The model was simulated based on the calculations of the quantities of domestic wastewater. The supervised classification was used in the spectroscopy of the satellite image of the river by the ArcGIS software in determining the effect of the storm network outfall on the Tigris River. The image was classified into four categories, which are pure water, polluted water, shallow water, and plants. Storm network data was obtained the from Wasit Sewerage Directorate in the form of ArcGIS files. The QuickBird satellite with a high spatial resolution of 25 cm was bought in 2019. The results of the study indicated that sewage quantities were discharged into the river, which led to water pollution by 17.79% from the river surface area. It was concluded from the results that the outfall of the storm network has a high impact on the river water quality. Therefore, this study suggests implementing and managing a separate sewage network that is directed directly to the treatment plants. A stormwater management model (SWMM) was used to simulate a storm network as a sewage network in dry weather.
