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.
A lagoon system consists of two components: a septic tank and a small earthen pond with a uniform 3-foot depth. A septic tank is a large, watertight, corrosion-resistant, buried container that receives raw sewage from the plumbing drains of the home.reeboard, or the distance from the three-foot operating level to the top of the berms, should be 24 inches (18 inches minimum) to keep surface runoff from entering the lagoon.
