Growth Composition Analysis Method Logistic Curve Method Population depends enngineering living conditions, environment, industrial potential, state of development, location w. Decreasing rate of growth method. Birth, death, lecyure etc. Population-time curve under such condition would be an ideal one known as a logistic curve S-shape as shown.

Quite rational method for the cities whose rate of increase goes on reduce, as they reach saturation. Residential Sngineering Industrial 5 City develop in a definite way based on the master plan. The population of town for the last four census years was recorded as below.

Determine the population in by using Arithmetic Increase Method: Census Population Increase in Population Sol.: Determine the population in by using Geometric Increase Method: Determine the population in by using Incremental Increase Method: The population of the city are as below.

The population of the city are as below.: Year Population,Find out the population noges one two and three decade environ,ental last known decades by using Arithmetic Increase, Geometric and Incremental Increase Method? Sub Surface Sources of water: These are the artificial structure created by the excavation of trends into a ground.

Obtain their quota of water from an aquifer below an impervious layers. The ground water comes to the surface under pressure. This formed due to presence of crack in impervious layer. These kind of source provide uniform quantity of water through out the year. This springs develop due to overflowing of the ground water. Flow from such a spring varies with rise or fall of snvironmental ground water table. This spring will be formed when subsoil water is exposed to the ground surface by the obstruction of an impervious layer.

The quantity of water available is small and uncertain. Cut off wall may be constructed to develop such a springs.
