Meandering or river and Formation of Oxbow Lakes. Plains of the United States. Lake stratification is the tendency of lakes to form separate and distinct thermal layers during warm weather. Based on this a general classification of lakes from pulsed systems to constant systems can be made (Jul-Larsen et al., 2003a). Materials, IAS Toppers 10 micro g/L of total phosphorus concentration at spring overturn designates an oligotrophic lake. Lakes can be grouped based on hydrology, average depth, surface area, shoreline configuration, as well as sensitivity to pollutants and recreational use. Prelims Answer key, APPSC The shallow bed of these lakes is usually an insoluble layer of sediment so that water is impounded, resulting in the formation of lakes.

Year Exam Papers And Solutions, PSU Recruitment 2007). The most common classification of lakes is based on the size or dimension of lakes, whether it is small, big or very large. For example a value of <10 micro g/L of total phosphorus concentration at spring overturn designates an oligotrophic lake. The aquatic vegetation present in lakes in the delta of the River Danube was studied using field survey data and satellite image. Organic lakes . The sudden release of water from these lakes like this can also cause floods, Example Lake Gormire in Yorkshire, blocked by a landslide, Besides natural lakes, man has now created artificial lakes, Artificial lakes are created by erecting a concrete dam across a river valley, These dams help in creating a reservoir by impounding river water, Guru Gobind Sagar Lake which supports the Bhakra Nangal Hydel Project is an example of an artificial lake in India.

Extremely small values are found in only a few lakes with highly localized deep holes (ponors or sinks, sublacustrine kettle holes). The Trophic State Index (TSI) is a classification system designed to “rate” individual lakes, ponds and reservoirs based on the amount of biological productivity occurring in the water. The excessive level of nutrients, especially phosphorus and nitrogen gives rise to an abundance of aquatic plants in these water bodies. Values >10 micro g/L … Results, RPSC This classification was based on decision rules related to the share of arable land as compared to grazing land and to the share of irrigated versus non-irrigated arable land. Many karst lakes only exist periodically but return regularly after heavy rainfall. Answer Key, CDS Exam Lakes are commonly classified based on their productivity. Values >10 micro g/L result in oxygen depletion in the hypolimnion. However interesting age and formation may be, placing lakes in a class system is probably best by considering lake quality. These circular hollows, in the heads of the valley up in the mountain, are called cirques. Under this type of lake, the crust of a hollow lava flow may collapse. In this study, we build on these conceptual advances by forging a flexible lake classification system for Wisconsin lakes (i.e., one that allows lakes to change classes over time) for use in conservation management of inland Wisconsin fisheries. Low productive oligotrophic lakes are generally deep and clear with little aquatic plant growth. Carolina Bay lakes). The classification results were validated by 284 investigation sites data and visual interpretation of Gao Fen 2 (GF-2) image.
