• Hydraulic Analysis on Agriculture Irrigation System

    Ivor Maasin

    I have a short agricultural irrigation system (a main) that provides water to farmers. The head of the system is a canal with a structure that provides a constant head of water elevation during the season. There is no pump to deliver water to the customers…

    Hello, I am using Bentley HAMMER to model a pump system that pumps water from a reservoir at low head to a reservoir at high head. The difference in head between the two reservoirs is approximately 600 ft. I am trying to study the transient effects…

    I am modeling a sewer system that is a combination of gravity pipes and forcemains. Some of the forcemains have isolation valves that can be closed to route the flow differently. However, SewerGEMS does not have the isolation valve feature. How can a…

    My model consists of a reservoir from a higher elevation supplying water to two tanks at a lower elevation. The pipe leading to the tanks keeps going to a negative pressure despite the inclusion of air valves. How can I correct this?
