The Caspian Sea is the largest lake regarding the area. Due to faulting, a rift valley is formed by the sinking of the land between two parallel faults, deep, narrow and elongated in character. The second analysis classified sites based on differences in their site or environmental conditions and examined how these compared to classifications based on productivity. The major role played by lakes and reservoirs is the regulation of stream flow. 3. - Recruitment Notification, TPSC Course, Target - XII Pass Classification of similar productivity zones in the sugar cane culture using clustering of SOM component planes based on the SOM distance matrix Miguel BARRETO… Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.

Classification of lakes based on quantitative trophic indicators such as phos-phorus (P) concentration, chlorophyll-a and transparency also allow the trophic status of lakes on a large gradient to be defined [4]. A trophic (productivity) classification of lakes based on these criteria is probably the most important tool resource managers have that indicate a lakes ecological well being. minus. Engineers Zone, Mitrapal - Mitra's PSC, Jammu & Kashmir Lakes are classified into various types based on their origin or mode of formation. (SSC/Banking), Rahul Agnihotri They usually have clear water with submerged aquatic plants. 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. Many lakes are aged as much as 20 million years (Aral Sea, Baikal, Caspian, Prespa, etc.). A eutrophic lake is highly productive (> 1,000 mg C•m-2•d-1) with low Each of them is placed in a different category, though in a few cases the lake could have been formed by more than one single factor, One more type of lake formed due to subsidence of a volcanic land surface is included under this type. Batch by Dr.Sudarshan Lodha, General Pankaj Singh, Foundation A glacier on its way down the valley leaves behind circular hollows. Trophic Classification of Texas Reservoirs 2020 Texas Integrated Report for Clean Water Act Sections 305(b) and 303(d) The primary productivity of reservoirs, as indicated by the amount of nutrients (phosphorus and nitrogen) and the extent of algae (suspended, floating, and attached) and rooted aquatic plants, can have a significant effect on water quality. Answer Key, KPSC Course, Pavan Kumar - An operational definition for management purposes sets a lower limit to a lake volume of about 1000 m3 (Meybeck, 1995). (2016). off, Current Myvatn Lake of Iceland. In regions of unreliable rainfall, lakes dry up completely during the dry season. ADVERTISEMENTS: Lakes in temperate latitudes exhibit marked seasonal temperature changes which may be described as follows: Winter: During winter the coldest water forms ice at 0°C (32°F) and floats at the surface. 2018, RRB JE Net Primary Productivity (NPP) is an important parameter, which is closely connected with global climate change, the global carbon balance and cycle. Data for each item were then aggregated across specified AEZs to arrive at climatically broader and less numerous systems, for example, humid + subhumid tropics and subtropics. Course, Fresher - Based on this a general classification of lakes from pulsed systems to constant systems can be made (Jul-Larsen et al., 2003a). Lakes can be grouped based on hydrology, average depth, surface area, shoreline configuration, as well as sensitivity to pollutants and recreational use.

At the intake for irrigation water, pH shall be between 6.0 and 7.5 and DO shall be more than 5 mg L-1. Mains Optional Subjects, UPSC Aquifers in geological terms are referred to as bodies of saturated rocks or geological formations through which volumes of water find their way (permeability) into wells and springs. PSC - Exam Pattern and Syllabus, Mizoram Course, Success Point IAS Introduction The measure of the rate at which work is performed is called “productivity”. 3. Fjord lake: A lake in a glacially eroded val ley that has been eroded below sea level. Group 1 Answer Key, TPSC Lake basins are formed due to endogenous geological processes like tectonism and volcanism and exogenous activities like landslides, glaciation, solution, river and wind action.

Syllabus, KPSC Toppers Preparation Strategy, IAS Study Using the index, one can gain a quick idea about how productive a lake is. These lakes include some of the oldest, deepest and largest lakes around the globe. Exam Date, SSC Answer These lakes are formed by filling up with water in the tectonic depressions created due to warping, sagging, bending and fracturing of the earth s crust. Due to the absence of intermixing of the water, the bottom layer of the lake contains no dissolved oxygen and is therefore largely devoid of life except for the purple sulfur bacteria. Syllabus, UPSC CAPF Many karst lakes only exist periodically but return regularly after heavy rainfall. 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.

Optional by Majid Husain, Law Optional & Test Series by Aditya Tiwari, Integrated Pre Cum Mains 4635-4637. The classification system is based on productivity and other abilities in the mechanized process. In the hot deserts, lakes disappear altogether by the combined processes of evaporation, percolation and outflow. Water supply Class I: can be treated by a simple purification process such as filtration. Karst lakes are formed in depressions, carved out by solvent action of rainwater on water-soluble rocks such as limestone, gypsum and dolomite. Meromictic lakes have layers of water that do not intermix. Answer Key, JKPSC Often, Paleolakes are identified based on relict lacustrine landforms such as coastal landforms that form recognizable relict shorelines, referred to as paleo-shorelines. Materials, Answer Civil Prep Strategy, IES verse lakes into subsets based on similar characteristics. 2007). Such lakes are referred to as the Cirque or tarn lakes, Example Red tarn in the English Lake District and Chandra Taal (Himachal Pradesh) in India, These are depressions in the outwash plain left by melting of a large mass of stagnant ice, They are irregular in shape, and also these lakes are not very large or deep, Example Kettle-lakes of Orkney in Scotland, These lakes are formed by ice scouring when valley glaciers or ice sheets scoop out hollows or depressions on the surface.

Among deep lakes, caldera lakes, graben lakes, and fjord lakes, D v will be much greater than 1.5 (also in many rock basins). Pradesh MPPSC, Rajasthan The water at increasing depth below the ice is progressively warmer and denser. Trophic level states a Waterbody’s Ability To Support Plants, Fish, and Wildlife. By contrast, high productive eutrophic lakes are generally shallow, turbid, and support abundant … An oligotrophic lake has low productivity (50 - 300 mg C•m-2•d-1) with clear water and low nutrient concentrations (Wetzel 2001) (Table 1). On the Relation between the Oxygen Deficit and the productivity and Typology of Lakes. the Great Lakes Based on Carbon Fourteen Measurements on Primary Productivity . 2012) or for identifying stream thermal regimes (Maheu et al. General Studies, IES For example the Great Lakes in North America. These lakes have medium-level nutrients and are usually clear water with submerged aquatic plants. In dormant or extinct volcanoes, due to rainfall straight into these depressions which have no superficial outlet, a crater or caldera lake is formed. Tutorial (RRB), UPSC Affairs, Current Lakes (water bodies classified as lakes, ponds or reservoirs) with TSI values below 30 are considered to have … Optional Booklist, UPSC Trophic(pronounced TROH-fik) means “of or relating to nutrition.” 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. Lakes are a good refuge for an enormous variety of flora and fauna. The range of 5-15 micro g/L total phosphorus is generally accepted as best for salmonid species.
