The present paper reviews on the application and management of water works through GIS. GIS Data can be categorized as spatial and non-spatial data, which can be stored, manipulated, analyzed and displayed with multiple users which can help in comprehensive solutions in a systematic way. GIS application is very common in construction industry, construction safety, flood studies, pipeline management which includes water works and severage.Project management through GIS is different from GIS based projects, the review briefs about the difference between the two. The pipe network management includes planning, designing, and management of the network, the planning is done using Remote sensing, photogrammetry drone or field survey method depending on the budget and objectives of the project. The designing of the network is done in GIS or separate application environment. The final step is the operations and management of the network which is in

The main aim of this study is to carry out source apportionment of PM10 for industrial locations of Vapi and Ankleshwar in Gujarat, using the Chemical Mass Balance (CMB) receptor model. Materials and methods: At six distinct locations of Ankleshwar and Vapi, respirable dust samplers were used to collect particulate matter on quartz filter sheets for the current study. Filter papers containing PM10 mass were subsequently examined for Water Soluble Ions (WSIs), major and trace elements, elemental and organic carbon followed by source apportionment study. Results: Using CMB, the contributions obtained for Ankleshwar are 27.85% for crustal or soil dust, 26.31% for fossil fuel combustion, 21.06% for vehicle emissions, 14.20% for secondary aerosols, 9.30% for biomass, and 1.20% for industrial emissions. CMB for Vapi revealed the chief source...

But these sensors require expensive equipment and skilled personnel, external power, as well as the acquired data needs to be processed such that some sense can be made out of it. Thus, a new method of Structural Health Monitoring using Mechanoluminescence materials that don't require external power seems quite promising, but being in the initial stage of research and development it comes with its own set of challenges. This study tries to understand the synthesis methods available to synthesize Strontium-based Mechanoluminescence sensors, their working, the embedment processes, and their performance when subjected to loading.

Microcontrollers are used to collect the data from the sensors and then the data is evaluated which can be done in real-time which ultimately helps us to know whether the structure is safe or not. Other than these conventional types there are other sensors such as mechanoluminescence (ML) sensors that do not require any external power. ML is a form of luminescence that is produced by mechanical forces such as fracture, friction, stress, crack, tension and compression. This aids us in directly visualizing stress and cracks on the structure’s surface. This review paper aims on discussing some common and widely used ML material along with some of the synthesis and loading techniques.

This further leads to environmental pollution and deterioration of soil as well as groundwater quality in many cities. Improper management of solid waste results in several challenges for the city inhabitants, predominantly those living around these solid waste dumpsites. If not handled properly, these dumpsites have the potential of polluting various air, water sources, land, and even vegetation. The current study was carried out for Uruli-Devachi dumpsite at Pune, Maharashtra with an objective to evaluate the groundwater quality and to confirm whether it is suitable for drinking. Samples of groundwater were taken from distinct locations including two bore and seven open wells for conditions before and after the monsoon. To ascertain the groundwater suitability for drinking, the physico-chemical characteristics were compared with Indian Standards. Th...

Traffic noise annoyance has become a major issue with the advent of fossil fuels and development in vehicle technology. Vehicular noise is dramatically increasing with the increased number of vehicle population, especially due to speeding vehicles. Amongst all the sources of noise pollution, vehicular noise has been identified as the most annoying and health impairing one. Therefore, it had become important to check the traffic noise and enhance the environmental condition along the transportation corridor. This study attempts the development of road traffic noise model for Indian condition. A statistical regression model for predicting road traffic noise is developed based on A-weighted equivalent noise levels.

Commonly, Indian coal comprises ash in the range of 30–45%. In order to sustain India’s economic growth, the country total coal demand is forecasted to more than double by 2030. Increasingly huge quantities of fly and bottom ash are produced in the country, thus leading to the necessity to duly plan safe and clean ways to handle, use, and dispose of the combustion by-products. Thermal power plant design nowadays must duly consider apprehensions related to water shortage, environmental guidelines, sustainable management and disposal of ash, along with growing consciousness pertaining to overall cost and power plant efficiency. The current paper discusses the problems associated with fly ash and its handling and mitigation measures. Fly ash generated while burning of coal in thermal power plants can be utilised for several favourable uses like manufacturing of cement, road construction, road embankment and development of ceramics or fertiliser.
