Today the ram constitutes a reliable and low-maintenance, sustainable alternative to motor-driven pumps. The hydraulic ram uses the kinetic energy of water flowing in a driver pipe to pump up about 10% of it to a higher elevation. Thereby, no external energy input is needed. As a lot of...

This study aims to improve the knowledge of the water quality and usability of the Iishana pans by evaluating the condition of water bodies during a drought period based on nutrients, pollutants, and sediment loads, to figure out possible pollution sources. Is the water of the Iishana usable ...
The age data only accounted for 6 of the 2574 field observations used to calibrate the groundwater-flow models, yet they were among the most influential for refining estimates of hydraulic conductivity, recharge, and seepage from the reservoir. Results from this study demonstrate the benefits of ...
resulting in low hydraulic efficiencies of the wells; 3) line power to the mine is limited, mandating efficient pumping over a wide range of yields and lifts; and 4) the relatively isolated northern setting and extreme cold winter temperatures (which can reach -40 to -60 deg C) present log...
Environmental protection is becoming a primary objective when choosing processes and technologies for treating oily waters resulting from hydrocarbon production. The focus of treating oily waters is to eliminate contaminants from effluents before dischar
hydraulic conductivity, depth to groundwater, specific yield, and elevation were the most important factors (average merit > 0.1), followed by geology, fault density, drainage density, soil, LULC, and distance to faults (average merit < 0.1). The average merits for the remaining factors were ...
The hydraulic elements of a water network can be defined as active or passive elements. The active elements can be operated to control the flow and/or the pressure of water in specific points of the network, such as pumps and valves. Additionally, the passive elements are those receiving the...
We used social network analysis (SNA) to identify the types of water-related conflicts between the users and members of the institutional arena of the Rio Mayo Irrigation District (RMID) within the ancestral territory of the Yoreme Mayo indigenous group
In independent systems coupled with low temperature emitters, a hydraulic disjunctor is necessary (Figure 1). For this reason there are two pumps: the built-in generator pump, that works only when the burner is operating, and the secondary circuit pump (three positions speed control), that ...
