Types of erosion. Soil erosion is a widespread problem in rural and urban Queensland. If we want to save our soils, we need to understand the different types of erosion that can occur. Water erosion. Queenslandâs high intensity summer rainfalls represent a significant risk of erosion by water.
What is a Lagoon? Lagoons are shallow coastal bodies of water separated from the ocean by a series of barrier islands which lie parallel to the shoreline. Inlets, either natural or man-made, cut through barrier islands and permit tidal currents to transport water into and out of the lagoons.
If sulfur is present, hydrogen sulfide, an odorus compond, may be produced. Particulate matter that does not get degraded will settle to the bottom. Facultative Lagoon-These lagoons have both an aerobic zone and an anaerobic zone. They are typically 4 to 8 feet deep, with a retention time around 25 days. Algae thrive in the top layer of the lagoon and supply oxygen via photosynthesis.
