The effects of water erosion are usually more visible than wind erosion. One can readily see gullies, turbid or muddy water, and sediment build-up. Storm water runoff can cause stream channel erosion, overland erosion, or both. Channel erosion occurs both in intermittent and permanent waterways and streams. Three causes of channel

contact us· Negatively charged particles won''t come together and can float in liquid suspension for hours, weeks, and even years. A simple example is muddy water created by aggregate producers who wash sand and gravel. When a coagulant is added to the muddy water, it creates a coagulation process that neutralizes the particles'' negative charge.
