Seawater Intrusion: Introduction, Causes, Measures & Research Scope

Image
Introduction: India is having about 7516 km long coastline around the borders. Besides considering the population of India around 25% of the population lives nearby the coastline. Moreover, coastal zones are having most of the industries over it. India has a wider eastern coast compared to the western coast which is more saline due to the presence of the Arabian sea [1] . The availability of saline water within the nearby range of habitat elevates the problem of seawater intrusion. The eastern coastal zone is having to sever the problem of intrusion where considering states Gujarat and some parts of Maharashtra are having very low intrusion problems. The amount and the reasons related to the seawater intrusion can only be found by the filed based research studies [2-10] . In simple words, violation of saline water into the fresh groundwater aquifer is considered as a seawater intrusion [11] . In the normal scenario, seawater is obstructed from entering into an aquifer due

Zero Energy Building: Concept and Understanding the Factors to Achieve it.

Zero Energy Building Concept: The energy sector of India has evolved and made astonishing progress over recent years. Considering electricity production and consumption, India is the third-largest producer as well as the third-largest consumer   [3] [4] . It is notable that Renewable power generation also made impressive progress which covers around 34.68% of the total capacity. The residential sector had a major impact on the consumption of energy which is about 24.76% of the total production  [5] . To minimize consumption there are many ways to achieve it. Zero Energy Building (ZEB) for the residential sector is one of the solutions to reduce the overall consumption of energy. In simple words, ZEB is the building using renewable technologies to meet the energy demand balancing the total supply  [1] . The concept of ZEB is using the terms at which a building is utilizing the locally available renewable resources to produce the electricity where the total produced energy a

A Case Study to Understand Rammed Earth Construction

Image
Introduction to Rammed Earth Soil is the most versatile material to use in the construction industry. It is been used in the construction industry in many various forms. Rammed earth is one of the fields for its application. Just like soil stabilization , it is an ancient and traditional technique that has revived again in this modern era with a different view. The use of rammed earth technique started a long ago but disappeared due to other sound materials and their better performance. Although, having several disadvantages rammed earth has reappeared as an alternate of other construction methods to save the environment. In recent times rammed earth construction industry has evolved dramatically because of its greater aesthetics and other environmental advantages. Rammed earth is compacted earth having various material homogeneously mixed together with soil/dirt. It is very easy to apply as a normal wooden form-work and a rammer is required with little skills to act [1] . It c

Impact of Marble Powder and Brick Dust on Engineering Properties of Black Cotton Soil

Image
The present article is based on one of my research on the soil stabilization . It is an experimental analysis of the effects of waste/by-product materials on the black cotton soil. Materials and Methodology: Materials: For the consideration of environment-friendly and waste/by-product materials we selected marble powder and brick dust as a stabilizer for this project. Marble Powder: Marbles Powder produces from the cutting and grinding of marble stone. It is having very fine particles along with non-plastic characteristics. The use of traditional techniques to stabilize the soil faces problems like high cost, and/or environmental issues. The improvement of soil by marble dust is an alternative solution as it is a by-product material and available at very cheap rates. For the stabilization we have utilized Dolomite Powder which is a form of Marble Powder having a high degree of purity and whiteness. Brick Dust: Brick Dust is a waste material produced at the traditional
