SJR is a measure of scientific in uence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals from which such citations originate. It measures the scientific in uence of the average article in a journal it expresses how central to the global. This indicator counts the number of citations received by documents from a journal and divides it by the total number of documents published in that journal. The graph shows the evolution of the average number of times that documents published in a journal in the last two, three and four years have been cited in the current year.
Evolution of the total number of citations and journal self-citations received by a journal's published documents during the three previous years. Journal Self-citation is defined as the number of citations from a journal citing article to articles published by the same journal. Evolution of the number of total citations per document and external citations per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years.
External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal's documents. 1/3/2020 International Journal of Civil Engineering and Technology (IJCIET), Scopus Indexed Journal, Journal Impact Factor Hi.

The longest prefabricated plate strip weighs only 2.25 kN. The stability of the prefabricated plate strips for large-scale use was further checked by field load tests. was 4.32 kN/m which was beyond the dead weight of 1.127 kN/m.Sharma [2] et.al., conducted a study on the design and construction of prefabricated hollow or ribbed plate.

The results indicate that the addition of polymer in the mortar matrix and the use of 4 x 20-mesh wire mesh, instead of 6 x 22-gauge wire, significantly increased the load-carrying capacity of the elements. A method to predict the ultimate load carrying capacity of the ferrocement flexural elements is also proposed. In the sheet part of the test specimen, different types of mesh are used as reinforcement.
Mesh types: Expanded metal mesh, Fiber mesh, Chicken mesh and galvanized iron mesh with 12.5 mm mesh size have been used as primary reinforcement in the plate part of the test specimen. The load was increased at regular intervals and the deflection was noted at the L/3 distance of the test specimen. Sheela, N.

The study of heat transfer processes in tail heating surfaces of the hot water boiler. The purpose of the study is the heat transfer process in the air heater for the boiler unit KV-T- 116.3-150. The air heater (AH) consists of two fields of the tubular heat exchanger located in the exhaust duct.
The nature of the temperature change along the control line I-I is shown in the graphs (Figures 3, 4). This resulted in the equalization of the temperatures over the surface of the heat exchanger. The distribution of the heated air velocity at a heat output of 50 Gcal/h for the contaminated and cleaned surface in the obtained AH model is shown in Figure 6.
The distribution of the heated air velocity at a heat output of 100 Gcal/h for the contaminated and cleaned surface in the AH model obtained is shown in Figure 7. For the cleaned AH surface there is an increase in the average velocity of the heated surface . air to the required values at these capacities. The efficiency factor at minimum boiler load for the contaminated surface was 87.7% and for the cleaned surface 88.2%.
SIMULATION OF RIVERS WATER FLOW BASED ON DIGITAL ELEVATION MODEL
CONSTRUCTION
STUDY AREA
The Al-Jubaila rivers were previously dredged for groundwater discharge and flow near the Basra silo. Currently used to accommodate slums, the rest of the adjacent land uses are residential and commercial. The river Al-Ribat is attributed to the Governor of Basra (Ribat Malik bin Dinar), who ordered the digging of this river in this place.
Recently, these rivers have turned into shallow marshes where stagnant water and debris collect at bridges and culverts that enter rivers, as well as low-level areas of the river. This led to the reduction of the impact of the phenomenon of tides which in turn caused the pollution to increase and settle in the lower levels as the water no longer reaches the end of the rivers. Each satellite image corrected with the GIS program based on 8 ground control points for each image, the ground control points were obtained from the (Czech company BOCP) contracted with the Municipality of Baghdad to update the master plan for the city of Basra, where this company observed.
The satellite images with a resolution of (60 cm) are corrected in GIS depending on the GPS points and the georeferencing tool, with the RMSE of all satellite images after the georeferencing not exceeding 60 cm, as in Figure (1), Figure (2) and table (1), which illustrate an example of the steps of georeferencing the satellite images using the georeferencing tool. Based on the corrected satellite images, the GIS program has mapped all six main rivers of the city of Basrah, with their connections and all their tributaries. Figure 6the steps for using the GIS attribute table to calculate the length of the main rivers of the city of Basrah. Source: The researcher relied on the satellite image for the year 2015 and the (GIS) program.

- Inputs of HEC-RAS 1. Geometric data
- Outputs of HEC-RAS for the reality of rivers
- Outputs of HEC-RAS after applying the design proposals on the rivers' sections
The construction of a digital elevation model of the group of rivers in the study area is in progress which will be based on additional survey data. This was done to illustrate the topography of the earth and change in the shapes of sections with high accuracy. This data represents the digital elevation model built for the rivers of the study area, which determines the shape of the river current and defines the longitudinal and cross-sections of the simulation program along each river, as well as the distance between each cross-section.
To calculate the value of the Manning coefficient, the Manning equation was applied within each cross section. The currents Qj are calculated in each section in March and November based on the initial values of the Manning coefficient. The flow and velocity of the upstream of each river at zero time were calculated based on the boundary condition data (average tide levels in March and November), as well as.
The slope was based on the mean slope of the tidal water surface in the Shatt Al-Arab to represent backward water curves. The following image shows the water surface changes in the longitudinal section of the Ribat-Jbaila group for the highest level of tides in March and November. Shape of the river cross-section: When the model is applied to the reality of the river, the difference between the level of tidal waves decreases as we move from upstream.
The cross section's levels and their depths and upper width: In order to ensure continuity of runoff in the rivers and the absence of interruptions in the water cycle in any part
The lining of the cross-sections: The research proposes to line the river's current and their sections with concrete walls and beds, because the concrete has a low roughness coefficient.
The lining of the cross sections: The research suggests lining the river's stream and their sections with concrete walls and beds, because the concrete has low coefficient of roughness,
The longitudinal slope of the riverbed: The research suggests that the slope that connects the bottom of the rivers is equal to zero, that is, the riverbed of all the rivers in a horizontal
Design proposals for river's stream: to ensure that no infringement or impact on any land use adjacent to the banks of rivers, and to ensure the exploitation of the resulting areas of
After running the model according to the design proposals suggested by the research as geometric data, and relying on the tidal data as initial and boundary conditions, the model produced a results. These figures illustrate the results of simulations in March and November to show the increase in the flow energy and the flow velocity which led to the regularity of the water surface levels and the disappearance of the areas where the water cycle is interrupted in all parts of the water cycle. river. The research proposals have therefore achieved their goal of addressing the river's current and rehabilitating it if these proposals are accepted in design and if the.
