What Do You Know About Civil And Environmental Engineering?

Cholera is a disease caused by the consumption of contaminated water, particularly water that is contaminated with the bacterium Vibrio cholerae. This bacterium releases toxins in the intestines, leading to severe diarrhea and dehydration. If left untreated, cholera can be life-threatening. Therefore, drinking untreated water that is contaminated with Vibrio cholerae can result in the transmission of cholera. Malaria, chickenpox, and diabetes are not directly caused by untreated drinking water.

Aeration is the process by which air is circulated through, mixed with or dissolved in a liquid/substance. This process is commonly used in water treatment systems to introduce oxygen into the water, which helps to remove impurities and improve its quality. Aeration can also be used in the fermentation process for making alcoholic beverages, where air is mixed with the liquid to promote the growth of yeast. Additionally, aeration is used in aquariums to provide oxygen for the fish and other aquatic organisms.

DDT is used in agriculture to control agricultural pests. DDT is an insecticide that is effective in killing and repelling pests such as mosquitoes, flies, and other insects that can damage crops. It is sprayed on crops to protect them from infestations and reduce crop loss. Using DDT helps farmers maintain the health and productivity of their crops by controlling the population of pests that can harm or destroy the plants.

The purpose of a drainage basin is to collect rainwater and drain it off into a common outlet. A drainage basin is an area of land where all the water that falls within it drains into a common river, lake, or ocean. This helps to prevent flooding by efficiently channeling the excess water away from the area. Additionally, the collected rainwater can be used for various purposes such as irrigation, drinking water, or industrial processes.

The purpose of the NEPA is to promote the enhancement of the environment and establish the President's council on environmental quality. This means that the NEPA aims to improve and protect the environment, as well as create a council that focuses on environmental issues and quality. It does not specifically address policies for protecting the public, sponsoring water treatment efforts, or regulating corporations responsible for water pollution.

Modern environmental engineering began in mid 19th Century England. During this time, the Industrial Revolution was in full swing, leading to significant pollution and environmental degradation. As a response to these challenges, engineers in England started developing new technologies and methods to address environmental issues. This marked the beginning of the field of environmental engineering, which focuses on designing and implementing solutions to protect and improve the environment.

The Romans constructed aqueducts in order to prevent drought and create a clean, healthful water supply. They were known for their advanced engineering skills and were able to build these structures to transport water from distant sources to their cities. This innovation greatly improved the quality of life for the Roman citizens and helped prevent water scarcity and disease outbreaks.

The Harappan civilization is the correct answer because archaeological evidence suggests that they had a well-developed system of underground sewers more than 5000 years ago. The city of Mohenjo-Daro, a prominent Harappan site, had an extensive network of covered drains and sewage systems, indicating their advanced understanding of sanitation and urban planning. This demonstrates that the Harappans were ahead of their time in terms of technological advancements and urban infrastructure.

The correct answer is 8. This suggests that there are 8 topics included in the curriculum for environmental engineering.

Joseph Bazalgette is credited with designing the first major sewerage systems. He was a British civil engineer and was appointed as the Chief Engineer of the Metropolitan Board of Works in London in the mid-19th century. During his tenure, he implemented a revolutionary sewer network that greatly improved public health by effectively removing waste and preventing the spread of diseases such as cholera. Bazalgette's innovative design and engineering expertise played a crucial role in transforming the sanitation infrastructure of London and became a model for other cities around the world.
