classification of lakes based on origin

When the glaciers recede like during the end of the last glacial period about 10,000 years ago, patches of ice in the depression on bedrock created by glacial erosion are left behind. Nearly a mile deep and holding over 23,000 cubic kilometers water, it would require the total volume of all the Great Lakes … Impoundments of rivers that are defined as great ponds pursuant to section 480-B are classified as GPA or as specifically provided in sections 467 and 468. There are a few large lakes, but ponds dominate numerically (85%) B. Such aggregates constitute the basic unit of which the solid Earth is composed and typically form recognizable and mappable volumes. As the name suggests, such lakes are formed by the tectonic movements of the Earth’s crust like tilting, folding, faulting, etc. 269 The residence time of a lake is defined as the volume of the water in the lake divided by the discharge into or out of the lake. The Peninsular Rivers: Non-Perennial rivers: Mahanadi, the Godavari, the Krishna, the Cauvery, the Narmada and the Tapi and their tributaries. The deepest lake in the world, Lake Baikal in Siberia, was formed from tectonic activity. These lakes are usually formed in volcanic calderas or craters or when lahars or lava flows interrupt the flow of a river or stream. Landslide lakes usually do not last for long as they are of a rather ‘loose nature.’ Often flooding with a high number of casualties is the end consequence. Classification of Lakes. 1998 | The VDP general meeting adopts uniform classification principles for classified wines of German origin: The wines should have a clear, high-class profile based on origin, grape variety and taste. 3. In this entry, lakes are classified according to their geological origin. There are 100 million lakes in the world larger than 0.01 km2. A measure of how far you can sink a black and white circle into the water and still see the colors. This type of basin is referred to as a graben and is the mode of origin of a large number of the most spectacular relic lakes in the world containing a vast number of native plant and animal species. When ice sheets moved over flat rock surface with weakened areas of fissures, the rock could splinter and loosen to form the basin of “glac… Within the global hydrologic cycle, freshwater lakes constitute only about 0.009 percent of all free water, which amounts to less than 0.4 percent of all continental fresh water. Part of Springer Nature. Development and validation of a global database of lakes, reservoirs and wetlands. Surveys may be secondarily classified under no. of headings which define the uses or purpose of resulting maps. A., Praire, Y. T., Cole, J. J., Duarte, C. M., Tranvik, L. J., Striegl, R. G., McDowell, W. H., Kortelainen, P., Caraco, N. F., Melack, J. M., and Middelburg, J., 2006. The Trophic State Index (TSI) is a classification system designed to rate water bodies based on the amount of biological productivity they sustain. Tectonic lakes are deep. This service is more advanced with JavaScript available. Lakes can be classified in different ways, according to their geological origin, to their trophic state (see Trophic Lake Classification in the Encyclopedia), which is according to the biological status, according to the thermal regime (see Thermal Regime of Lakes and Stratification in Lakes), which is related to the climate, or according to the hydrological conditions relating to the character of the in- and outflows … Chapter 3 SHAPE AND DEVELOPMENT O F LAKE BASINS A lake basin may be classified by reference to its geometric shape which, incidentally, generally results from mode of origin. Lakes and rivers are divided into the following classes based on a combination of factors. As the river flows, a number of lakes are formed by the running water and are called the fluvial lakes. Lake Superior is the biggest fresh water lake. Hutchinson presented in it a comprehensive analysis of the origin of lakes and proposed what is a widely accepted classification of lakes according to their origin. Two other systems of classification which are based upon The department shall have one standard for the classification of great ponds and natural lakes and ponds less than 10 acres in size. Alongshore classification and super domain delineation of coastal belts based on interpretation of biophysical catenary sequences observed from We have tried to build a classification system that is simple and practical and that includes most of the boundary characteristics that ecologists care about. Based upon the physical properties and alignment, rocks may be classified into following types: Stratified rocks are those which exhibit distinct layers which can be separated. The ages of the geological periodsreferred t o are given in Appendix 11. A detailed study of the origin of lakes is given by Hutchinson (1957), who 1 distinguished 1 different groups of lakes with 76 types. In this kind of lakes, Evaporation > Precipitation. Lake Classification A lake’s ability to support plant and animal life defines its level of productivity, or trophic state. [1989, c. 890, Pt. UNESCO – EOLSS SAMPLE CHAPTERS GEOLOGY – Vol. Classification of Fish: Fish, the member of the Animalia Kingdom is classified into Phylum Chordata and Vertebrata Subphylum. Lakes are mainly created as consequences of tectonic, glacial, or fluvial processesbut there might also be other processes involved. Shoreline lakes are formed along the coastline or between islands and mainland mainly due to the deposition of sediments by rivers, wave action or ocean currents that result in the creation of a water body separated from a larger water body by such deposits. There are different types of spillways that can be provided depending on the suitability of site and other parameters.
