Water supply engineering: Water Supply Engineering is that branch of engineering which deals with the supply of water used for various purposes . Water moves in a cyclic process which is known as hydrological cycle in water supply engineering . In this engineering a scheme is constituted which is known as water supply scheme . The purpose of this scheme is to search a suitable source of water supply then giving it proper treatment to make it pure and at last to distribute this treated water at the required place . In ancient times people arrange the required water by their personal efforts but with the advancement of community and increase in population , the requirement of a well designed water supply scheme becomes compulsory . A civil engineer has a wide knowledge of hydraulic structures and various works connected with water supply system . Due to this reason this water supply engineering is connected with a civil engineer .

  Importance and necessary of water supply system  For any living being water , air , food , shelter , etc. are the primary needs , in purposes , few of them are :  ( a ) for drinking and cooking  ( b ) for bathing and washing  ( c ) for watering of lawns and gardens  ( d ) for heating and air - conditioning systems  ( e ) for street washing for fire fighting  ( f) for recreation in swimming pools , fountains  ( g ) for steam power and various industrial processes etc.        Without food human can survive for a number of days , but water is such an essential element that without it he cannot . In the ancient times human required water for drinking , bathing , cooking etc. but with the advancement of civilization the utility of water enormously increased , and now such a stage has come that without well - organized public water supply scheme , it is impossible to run the present civil life .        In ancient times every individual or family was responsible to arrange their water suppl

 HYDROLOGICAL CYCLE  Hydrology in the science which deals with the occurrence , distribution and movement of water on the earth , including that in the atmosphere and below the surface of the earth Water occurs in the atmosphere in the form of vapour , on the surface water , snow or ise and below the surface as ground water occupying all the voids with in a geologie stratum .   Water is lost in the atmosphere as vapour from the earth , which is ther precipitated back in the form of rain , snow , hail , dew , sleet or frost ete . This precipitation and evaporation continues forever , and thereby a balance 1 maintained between the two . This process is known as hydrologic cycle and  This cycle is also called water cycle .  Hydrologie cycle or the waler cycle is the process of transfer of moisture frou atmosphere to the earth in the form of precipitation , and movement of the precipitate water by streams and rivers to ocean and lakes etc. , and evaporation of water back C the atmosphere .

  Gradient  The rate of rise or fall of a road surface along the length of the road is termed as gradient. It is usually expressed as a ratio of 1 vertical in'n horizontal (i.e. 1 in n). For example if a road surface falls 4 m in a horizontal distance of 200 m measured along the length of the road, the road gradient is 1 in 50. Some times it is also expressed as percentage. Gradient is always necessary to drain off the surface water easily from the side drains. It should be remembered that surface water can be drained off to the side drains by providing camber to the road surface but a certain longitudinal slope (Gradient) is essentially required to drain the water along the side drains (easier flow of open drain water to some gutter, ditch or intercepting chamber). Gradient of a road depends upon the following factors:  () Nature of traffic : For slow moving traffic like Tongas and Bullock carts, Steeper pa e: gradient is avoided.  (ii) Natural Topography of area : To avoid unnec

Indian Road Congress As per the recommendation made by the jayakar committee, a semi government technical body was formed in 1934 to provide a platform for regular sharing of ideas and experience on all matters related to planning, construction and maintenance of roads in India. This body was named as India Road Congress . It works in close collaboration with roads wing of the Ministry of Shipping and Transpor, Government of India. It is now an active body of national importance controlling standardisation of specifications as regards material, design and construction of roads.  Function of I.R.C. 1) To collect information and literature on roads and make it available for use in the country. 2) To recommend standard specifications for road material, design and construction techniques. 3) To publish journals, research publications standard specifications and other guidelines on various aspects of highway engineering. 4) To provide a platform for the expression of professional opinion on

 1) VIVO X60  https://amzn.to/3dQHFkP The Vivo X60 Pro is my top recommendation of the sexiest phones of 2021. It`s got the looks, the in-hand feel, the build materials and an overall premium swagger oozing out of it. Vivo`s prowess in offering capable optical hardware is on display with the X60 Pro and it has the results to show for it. Performance and display metrics also put the X60 Pro at the very top of the smartphone pedestal, although you will notice the phone heating up from time-to-time under heavy GPU load. However, the battery life is sub-par and the software, while improved, still has bloatware. The lack of a few features like stereo speakers, IP rating, and wireless charging could be deal breakers though. If you are looking for something that feels light and premium in your hands, takes good photos and has the processing prowess to back it, the X60 Pro is a great choice. Oppo F19   Optimizes video portrait performance by automatically detecting and adjusting for light. Whe

Food chain                       Energy flows in the ecosystem in a certain pattern, where various trophic levels are connected through food chain. The sequence of eating and being eaten in an ecosystem is known as food chain. All organisms, living or dead, are potential food for some other organisms and thus, there is essentially no waste in the functioning of a natural ecosystem.  In nature basically there are two types of food chains. 1) Grazing food chain 2) Detritus food chain 1) Grazing food chain                                             Thse type of food chains start from green plants, goes to grazing herbivores and them to the carnivorous. Most of the ecosystem in nature follow this type of food chain. This type of food chain is directly dependent upon solar energy. Some common examples of such food chains are : Terrestrial food chain ( on land ) 1) Grass — Grasshopper — Frog — Snake— Hawk  2) plants — Rabbit — Fox — Wolf — Tiger  Aquetic food chain ( in water body ) ¹) Phyt
