A zero-carbon approach encompasses strategies, practices and rules across various sectors like energy, transportation, industry, farming, and construction to mitigate carbon emissions with the overarching goal of combatting climate change. Efforts involve transitioning to renewable energy sources, enhancing energy efficiency, carbon capture, promot...

Environmental Impact Assessment or EIA has emerged as an effective tool to undertake development without harming the environment under the aegis of sustainable development. Thermal power plants are important facets of any developing nation like India but they can be detrimental to the environment as well. The present research has put forth a sugges...

Solar energy is the future of green and sustainable energy that will not only ensure replacement of fossil fuel driven energy sector but would also aid in achievement of Paris Climate Targets towards a clean and green environment. At present, solar panels are usually oriented in a horizontal manner either at roof tops or grounds. However, such hori...

Blue-Green Infrastructure (BGI) is revolutionary approach designed and adopted by western countries to deal with rapid climate change in urban areas. In India, urban areas are dominated by grey infrastructure and with the increasing trend of population growth in urban areas which has resulted in poor air water quality, urban flooding, heat envelope...

As the Indian highway system continues to grow in mileage and traffic volume, it is important to construct highways sustainably and with low environmental impact. The construction of asphalt pavement in India has a significant impact on the environment, energy use and greenhouse gas, GHG emissions from asphalt pavement construction have been receiv...

Climate change is an all-pervading phenomenon impinging upon earth's natural equilibrium. Although once a natural phenomenon, it has now evolved as an anthropogenically induced phenomenon driven by accentuated greenhouse effect as a result of increased fossil fuel burning due to rapid industrialization and urbanization disturbing the environmental...

Climate change owing to Greenhouse Gas emissions is an all-pervading phenomenon impinging upon earth's natural equilibrium. Although once a natural phenomenon, it has now evolved as an anthropogenically induced phenomenon driven by hyper-urbanised way of life leading to accentuated greenhouse effect as a result of increased fossil fuel burning owin...

Radon is an element that is radioactive in nature. Although, one can not see, smell or taste it but since it remains dissolved, there is a high likelihood of radon exposure through water drunk from wells or other ground water sources. It is primarily formed due to radium decay and is hence found in rocks and soils. It then escapes to the earth's cr...

Carbon cycle is one of the most important Biogeochemical Cycle on earth. It is the basic element of all life forms on earth. Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. Carbon in the atm...

River is dependent on many aspects for its own health and self-sustainability. One of the major factors are surrounding lands known as the watershed, storm water / sewer water disposal practice, local temperature, annual precipitation for a consistent supply of clean water. With urbanization, mostly human activities have greatly influenced the heal...

Agriculture is the world's largest and most impactful economic pursuits of the world. Its impacts are most palpable over the environment that in turn impacts the society. Thus this sector that has three pillars of economy, environment and society, has a direct synergistic relationship with sustainability. On one hand, this sector marrs the environm...

Sustainability is most often defined as meeting the needs of the present without compromising the ability of future generations to meet theirs. It has three main pillars: economic, environmental, and social. These three pillars are informally referred to as people, planet and profits 3Ps. whenever we talk about sustainability, we talk about various...

Terrestrial water storage can be defined as the summation of all water on the land surface and in the subsurface. It includes surface soil moisture, root zone soil moisture, groundwater, snow, ice, water stored in the vegetation, river and lake water. Gravity Recovery and Climate Experiment has provided an unprecedented view of the terrestrial wate...

Debris flows are fast-moving landslides that occur in a wide variety of environments throughout the world. Some landslides move slowly and cause damage gradually, whereas others move so rapidly that they can destroy property and take lives suddenly and unexpectedly. Debris flows, sometimes referred to as mudslides, mudflows, lahars, or debris avala...

Construction work would have been convenient to execute if they are exposed to perfect weather conditions from concrete pouring and setting time throughout the year. All concrete must be protected from freezing until it has reached a minimum initial compressive strength, which typically achieved within the first 24 hours. If concrete freezes while...

Snow avalanches have always been a big threat for people and infrastructure in mountainous regions. Increased population and climate change leading to global warming is triggering this catastrophic event often across the glacial mountains of the world. Physical criteria and mathematical models to describe avalanche movement are amongst the most imp...

Sensing concrete has the capability to sense its condition and environmental changes, including stress or force, strain (or deformation), crack, damage, temperature, and humidity, by incorporating functional fillers. In addition to having highly improved mechanical properties, sensing concrete has multifunctional properties, such as improved ductil...

Climate variability, change in environment conditions and its resulting extreme events has caused serious disasters over the past decades. Flooding became more severe in low lying coastal areas due to increase in sea level. Growth of urbanization towards coastal regions has caused depletion in green areas such as mangroves, coral reefs; which other...

Alternate Storage is an arrangement to store water in addition to main reservoir in nearby catchment area, and this scheme can be very much effective for "run of the river power projects" in India.

Vulnerability of large landslides takes place due to many anthropogenic and natural factors. Frequent collapse and triggering of landslide take place in active foothills of Himalayan region. The main primary factors causing destabilization of slope includes rain water infiltration in the topmost weathered layer, earthquake forces and local inhabita...

A glacial lake outburst flood occurs when the dam blocking the glacier's path collapses. The dam may comprise glacier ice or a terminal moraine, eroded material from the sides and bottom of a valley, which the glacier pushes to the front. The collapse may occur due to erosion, build-up of water pressure, an avalanche, heavy snow, earthquake, volcan...

Shed Tunnel Design for Himalayan Roads

Hazards provoked by released rocks and slides due slope instabilities from loose, disintegrated and weathered surfaces in potentially risky areas often occur and are able to cause considerable damages to human beings and infrastructure. Continuous shooting stones at the crown portion of the tunnel and adjoining slopes under study poses a considerab...

Capacity enhancement if poor railway subgrade.

Concrete which has microscopic bubbles in it is called Air entrained self compacting concrete. The method of forming a small tiny bubble in the concrete is known as Air entrainment. During the concrete making process, some air entraining nano-particle along with inorganic salt enhancing self-compaction of concrete are added in the concrete which fo...

Anthropogenic activities and natural factors have created catastrophic condition in the seismically active young Himalayan foothills. Continuous build-up of pore pressure in the slope creates decrease in intermolecular shear strength due to lubrication between these particles and rock joints. In addition, toe erosion in the valley side due to Peren...
