Hydraulic dredging can cause visible trenches along the seafloor; redistribution of dredged material; altered substrate composition; and creation of deep, wide and curvilinear furrows while the magnitude of these changes is largely determined by sediment type (Kyte and Chew 1975; Gilkinson et al. 2003).
Beverages, sugar and salt. Beverages like coffee (caffeine), black tea, alcohol and soft drinks are known to accelerate mucus buildup. Black tea contains the most caffeine, and it creates excess mucous. Processed foods containing salt and sugar produce mucus in the body.
Avoid mucus forming foods such as fried foods, meat and dairy products. Foods that help loosen mucus include spicy foods, hot chili peppers and horse radish are effective at loosening mucus. Drink plenty of warm liquids such as herbal teas to moisten the airways and break up mucus. Using a vaporiser or humidifier at night will help thin mucus (I use a vaporiser, both are good).
