Non linear flow augmentation model has been presented here. The model is built on an analogy of load flow problem in an interconnected power system; with a proven convexity under the various constraints. It is capable of incorporating water quality of the augmentation source, and changes in the water quality in river base flow due to augmentation. Further, the mathematical model has been used to p...Show More
Water shortages have increased in recent years due to overpopulation, climate change, aging water facilities, and water leakage due to damaged pipes. The issue is not the volume of water leaking, but rather the time it takes to notice and fix the problem. Water delivery systems are necessary for the sustainable use and conservation of water resources. This summary provides a concise overview of sy...Show More
This project introduces some features in water management: a real-time water quality monitor and leakage detection features that work with IoT. There is inaccuracy in traditional methods which delays in detecting leaks and communication. There is also an inefficiency in resource allocation and cost management. Therefor the selected system uses sensors to gauge the critical parameters of water qual...Show More

Water scarcity affects more than 4 billion people in the world. One of the most critical challenges faced by the world is water shortage. The proposed idea aims to conserve water, by introducing a regulatory system that reduces the rate at which water is obtained at the outlets in a house after a specific volume. The proposed system must be installed at the inlet of every house. Once 80 percent of...Show More
In our society, we see water tanks as reservoirs, which are typically placed on the rooftops of the buildings. Inconventional water storage tanks, an automatic water tank controlling and monitoring system is absent. Therefore, water wastage due to water tank overflow is a widespread scenario that occurs in our neighborhood now and then. If we consider the total amount of freshwater wastage due to ...Show More
The overall superficial velocity is a main parameter in oil-water two-phase flow in petroleum industry. The velocity distribution in the pipe is important for measuring it precisely. Pulse-wave ultrasonic Doppler technology has attracted much attention in the field of multiphase flow detection recently, which can obtain the velocity profile of fluid along the measurement line. A pulse Doppler meas...Show More

Smart devices have transformed nearly every aspect of our home and this paper is presenting a practical low-cost Smart Water Meter Device whic...Show More
Based on the work flow of steel rolling process, the water flow chart was built and its valuation index of water-use was confirmed by using the tracking observation principle of the material flow analysis theory combined with medium and small cycle theory of system energy conservation. The water-use status of steel rolling process was analyzed. A case study on a plant, its water-using situation an...Show More
In the exploitation of the irrigation systems, the water distribution nodes are subject to wear and tear of the mechanisms and devices for regulating the water levels, as well as the design characteristics of the outflow, and as a consequence the magnitude of the prescribed water quantity, which is intended to be distributed in a lateral or other type of branch canal, is violated. It is therefore ...Show More
