A study was prepared to select the appropriate pumps for pump stations in order to predict the decrease in the level of Iraq's rivers in general and problems in the pumping stations as a result of this decrease in addition the study was prepared to address the problems in the water pumping projects (pumping stations) in 2019 at the University of Baghdad, the study can be applied for all central and subsidiary water pumping projects spread throughout the provinces, note that the study includes

... e ( introduction of basic data such as the rise of the river level, dimension the location of the pump for the river, the required height for pumping water and the amount of water required to pump (m3/h), the diameter of the pipes to be used, connecting accessories, the number of entrances and exits of the system, check valves etc..). The study also includes the design of a floating pumping station to address the problem and the study also aims to reduce the financial cost in terms of the use of ideal pump set (motor + pump) for river level (upper and lower ) and thus reduce the engine horsepower, i.e. reducing the power of the engine required for operation, in addition to reducing the cost to buy expensive pumps with high horsepower, reducing the sizes and types of pipes used, as well as reducing the connecting accessories, and thus we have solved technical and economic problems at the same time. Keywords: centrifugal pumps; pumping projects; hydropower; brake horsepower. goal of the study: Will be studied how to choose the appropriate pump that provides the necessary pressure to draw the required water in case the river level is normal or low to the lowest expected level by studying the determinants that directly affect the work of the pump. In addition, the design of a floating pumping station is an additional solution.
