Leak detection in open water channels ⋆
In this paper we present a simple cumulative sum algorithm for detection of leaks in open water channels. The algorithm compares the observed changes in water levels against the known inand out-flows and raises an alarm if they are not in agreement. The algorithm is tested on data from an irrigation channel with very good results. Leaks are quickly detected and the algorithm is robust against u...
متن کاملMethods for the localization of a leak in open water channels
In this paper, we present two methods for determining the position of a leak in an open water channel. The available measurements are the water level and the gate position at the upstream and downstream end of a channel reach. We assume that the size of the leak and the time it started are already estimated by a leak-detection method. Both of the proposed methods make use of a nonlinear Saint-V...
متن کاملLEAK DETECTION IN WATER DISTRIBUTION SYSTEM USING NON-LINEAR KALMAN FILTER
Leakage detection in water distribution systems play an important role in storage and management of water resources. Therefore, to reduce water loss in these systems, a method should be introduced that reacts rapidly to such events and determines their occurrence time and location with the least possible error. In this study, in order to determine position and amount of leakage in distribution ...
متن کاملWater Velocity Measurements in Open Channels Using Volumetric Current Meter (VCM)
An innovative Volumetric Current Meter (VCM) was designed in order to allow quick velocity measurements in open channels. At first, the coefficient of velocity (Cv) of the device was determined through calibration under different water velocities in the laboratory. The measurement performance was verified by measurements performed in similar flows in irrigation channels using an ordinary curren...
متن کاملRobot Design for Leak Detection in Water - Pipe Systems
Leaks are major problem that occur in the water pipelines all around the world. Several reports indicate loss of around 20 to 30 percent of water in the distribution of water through water pipe systems. Such loss of water represents critical waste of valuable resources, especially in countries such as Saudi Arabia where water is scarce. Moreover, leaks provide pathways for outside contaminants ...
