As a result Biodiversity can be decreased. Releases of unnaturally cold water from reservoirs can dramatically change the fish and macro invertebrate fauna of rivers, and reduce river productivity.

The rising temperature changes the physical and chemical properties of water. In fishes, several activities like nest building, spawning, hatching, migration and reproduction etc. For instance, the maximum temperature at which lake trout will spawn successfully is 8. Increased vulnerability to disease: Activities of several pathogenic microorganisms are accelerated by higher temperature.

Hot water causes bacterial disease in salmon fish. Invasion of destructive organisms: Thermal pollutants may permit the invasion of organisms that are tolerant to warm water and highly destructive. Many of the planktons, small fish and insect larvae that re sucked into the condenser along with the cooling water are killed by the thermal shock, increased pressure and water viscosity.

As a result, food chains of the old and new environments may be compromised. Some fish species will avoid stream segments or coastal areas adjacent to a thermal discharge. High temperature limits oxygen dispersion into deeper waters, contributing to anaerobic conditions. This can lead to increased bacterialevels when there is ample food supply. Many aquatic species will fail to reproduce at elevated temperatures.

Primary producers are affected by warm water because higher water temperature increases plant growth rates, resulting in a shorter lifespan and species overpopulation. This can cause an algae bloom which reduces oxygen levels. Temperature changes of even one to two degrees Celsius can cause significant changes in organism metabolism and other adversecellular biology effects.

Principal adverse changes can include rendering cell walls less permeable to necessary osmosis, coagulation of cell proteins, and alteration of enzyme metabolism. These cellular level effects can adversely affect mortality and reproduction. A large increase in temperature can lead to the denaturing of life-supporting enzymes by breaking down hydrogen- and disulphide bondswithin the quaternary structure of the enzymes.

Decreased enzyme activity in aquatic organisms can cause problems such as the inability to break down lipids, which leads to malnutrition. In limited cases, warm water has little deleterious effect and may even lead to improved function of the receiving aquatic ecosystem. This phenomenon is seen especially in seasonal waters and is known as thermal enrichment. An extreme case is derived from the aggregational habits of the manatee, which often uses power plant discharge sites during winter.

Projections suggest that manatee populations would decline upon the removal of these discharges. In general, cold waters are better habitat for plants and animals than warm ones because cold waters contain more dissolved oxygen.

Many freshwater fish species that are valued for sport and food, especially trout and salmon, do poorly in warm water. Some organisms do thrive in warm water, often with undesirable effects. Algae and other plants grow more rapidly in warm water than in cold, but they also die more rapidly; the bacteria that decompose their dead tissue use up oxygen, further reducing the amount available for animals.

The dead and decaying algae make the water look, taste, and smell unpleasant Releases of unnaturally cold water from reservoirs can dramatically change the fish and macroinvertebrate fauna of rivers, and reduce river productivity.

In Australia, where many rivers have warmer temperature regimes, native fish species have been eliminated, and macroinvertebrate fauna have been drastically altered. Due to the sudden fall of water temperature the contraction on dam and bridge pylon may take place. In the United States, thermal pollution from industrial sources is generated mostly by power plants, petroleum refineries, pulp and paper mills, chemical plants, steel mills and smelters.

Heated water from these sources may be controlled with: Some facilities use once-through cooling OTC systems which do not reduce temperature as effectively as the above systems. During warm weather, urban runoff can have significant thermal impacts on small streams, as stormwater passes over hot parking lots, roads and sidewalks. Stormwater management facilities that absorb runoff or direct it into groundwater, such as bioretention systems and infiltration basins, can reduce these thermal effects.

Retention basins tend to be less effective at reducing temperature, as the water may be heated by the sun before being discharged to a receiving stream. Noise pollution is excessive, displeasing human, animal, or machine-created environmental noise that disrupts the activity or balance of human or animal life. The word noise may be from the Latin word nauseas, which means disgust or discomfort. The source of most outdoor noise worldwide is mainly construction and transportation systems, including motor vehicle noise, aircraft noise, and rail noise.

Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential area. Thermal pollution is the type of pollution in which the degradation of the water is done by any process which in result did the change of the temperature of the water.

Mainly the thermal pollution is done by the water coolant company which use the hydro power to cool the temperature of the water. Mainly it is done by the manufacture and the coolant infrastructure. Change in the temperature of the water typically decreases the dissolved oxygen of the water and is cause the result in the produce the pollution of the water and the result in the thermal pollution.

The gases like oxygen are the less soluble and it can dissolve in the water but if the liquid is hot then, in that case, the gas will not dissolve that liquid. By the thermal pollution in the aquatic animal the metabolism rate gets increase and in the result, the enzymes which help to digest the food in the organism is get increases and this result that animal start consuming more food in the less time and this will harm them. They will consume this amount of food till their body environment is not get change.

By this change of the metabolism of the body the food change of the living thing organism get change and this cause the compromised the environment of their body in the against of the water.

The high temperature of the water can create the reason of the niobic reaction in which the oxygen of the water cannot dissolve in the water.

If the temperature of the water is the same and constant then there is no any change of the thermal attack in the life of the aquatic living organism of the water. A small amount of the water can in the result of an unwanted activity in the living organism. If the temperature of the water is getting increase then the activity which is holding in the water is getting decreases.
