Water-level fluctuations (WLF) affect the ecological processes and patterns of lakes in several ways. Aquatic habitats and feeding or breeding grounds are gained or lost, as light, climate and wave impacts change to mention only a few phenomena. While the phenomenon of WLF has been studied in many rivers (better known as flood pulse, Junk & Wantzen, 2004) and environmental flows (Bunn et al., 2...

In this project, we have worked with an indicator on automatic water level controller. When looked up our topic the internet, realized that most of projects used microcontrollers or IC 555, but didn’t include any these circuits in model. Our design is based LM324N IC, which functions as a rectifier, oscillator, and comparator. On foundation, construct circuit, model successfully executed at min...
