It depends on how well this trade-off between these two drivers is managed which becomes critical for any country aspiring for high growth to meet its development objectives. A well-executed Environmental Impact Assessment (EIA) for projects helps in proactively addressing the environment protection aspect during the project life cycle, which very much depends on the site selection, construction and opera

Past few decades have seen raised understanding, awareness and concern on the impacts of PM on human health, air quality and climate globally. However, knowledge gaps related to its nature, formation, transport and impact continue to exist; particularly for those related to smaller PM (mainly ‘submicron PM’, also referred to as ‘PM1&a

Better conditions of roads can minimize travel time and lower the costs of transport and improve earning and ultimately the living standard. This two-way interaction gives benefits to consumer and also such accessibility creates more and more demand for further development. Transportation has become crucial in development and economy of the country and is an important part of our daily lives.1 Tran

Road network is vital for sustained and inclusive growth of the economy and consolidation of social diversification of the nation. When compared to other transport means, road transport is considered to be more flexible and consumer-friendly as it provides door-to-door service to the people even in the remotest parts of the country.

A number of models have been developed to establish rainfall-runoff relationship in ungauged catchments. The Geomorphologic Instantaneous Unit Hydrograph (GIUH) theory was introduced by Rodriguez-Iturbe et al.,1,2 by relating the peak discharge and time to peak discharge with the geomorphologic characteristics of the catchment and a dynamic velocity parameter. The tw

Inflow forecasts are used for optimum power generation during non -monsoon season and operation of gates and spillways during the flood season. In order to develop an inflow forecasting system for a reservoir, it has been observed that many a times number of ungauged rivers directly falling into the reservoirs are not accounted for. Such is

Many headwater streams and rivers are still intact from urban development. However, recent water resourcedevelopment such as water diversion and operation of hydropower dam and irrigation channels along with extraction of river-bed materials have deteriorated morphology and hydrology of rivers and streams and th

Many rivers in Nepal have largely been modified with the purpose of supplying drinking water, irrigating agricultural lands, producing hydro-electricity, and operating water mills. During the process, rivers are channelized and the river bed materials are removed. Such activities of river bed e

Rivers due to their function to transport the domestic, industrial wastewater and run-off from cultivated lands in their huge drainage basins are amongst the most susceptible aquatic forms to pollution. The surface water quality of any area is mainly dependent on both the natural processes and anthropogenic influences viz. municipal, industrial and agrarian activities, consequently leading to a huge u

The characteristics of synthesized mesoporous were analyzed by SEM/TGA. Optimal conditions were determined for important parameters such as solution pH, the absorbent dose, the initial Co2+ concentration, and contact time by a single-variable method through the batch experiments.

In this work, three sites in a roadside area were investigated for microplastics. Air samples were obtained by sucking air at these three sites into a stainless steel funnel with a vacuum pump. The air went through a filter media to retain any particles, which were then collected and observed with a digital microscope and Fourier Transform Infrared (FTIR) testing. A diver

Contamination of environment by radioactive elements is, perhaps, of more concern rather than on-spot casualties because of the long-term consequences associated with it. The memories of nuclear accidents such as Three Mile Island, Chernobyl, Fukushima Daiichi, etc. are still fresh to thousands of people living all over the world. Three Mile Island accident in 1979 was t

Personal Computer Transient Analyzer (PCTRAN) has been used to generate the response data of the plant safety systems numerically for an accidental condition like such. A break of 1000 cm2 in the A-loop of the steam line has been considered. A break of the size is considered a “Large Break”, wh

Globally, 50% of present drinkable water, 40% of the industrial water demand, and 20% of the irrigation water have been supplied by groundwater (UNESCO, 20031 and Molden, 20072). Rice is covered on 75% of the total cultivated land and is main staple crop in the country, comprising 90% of the total

For obtaining this self sufficiency, groundwater accessibility is continuously increasing that results in expansion of deep and shallow tube wells. Available evidence suggests that the policy focus so far has been largely on “resource development”, and not on “resource management”
