IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Determine the efficiency of hydraulic ram-pumps
From the early nineteenth century, migration from rural to urban areas as an important social phenomenon known
throughout the world. Uneconomical construction of water supply systems in sparsely populated rural or Impassable
rural for drinking, agriculture and animal husbandry, etc. and pull factors in urban, the increase in immigration has been
important. Ram pumps are used to transmit water to a higher elevation for more than 200 years. It consists of a system
with driver and delivery pipes, delivery and impulse valve and an air chamber. The frequent opening and closure of the
valves establishes a pulsatile flow which in turn results in pumping water to a higher level. The aims of this research are
to the introduction of the ram pump to overcome the problems of the water supply in the deprived areas of the third
world countries, and developed to an equation using experimental data to determine the efficiency of the ram pump. The
results are compared with the artificial neural network (ANN) results. According to the results, the proposed equation
better than the ANN to estimate efficiency of the ram pump. Therefore, the presented equation as a simple and the
precise equation is recommended to estimate the efficiency. In this equation, the value of RMSE and R2 are 0.0341 and
0.69 respectively.
