Leachate pollution index (LPI) value can be used as a tool to assess the leachate pollution potential of landfill sites particularly at places where there is a high risk of leachate migration and pollution of groundwater and thus can help to take necessary decisions as deem fit. In this paper, leachate treatment efficiency was evaluated on the basis of LPI value of leachate before and after tre...

To effectively combat the biodiversity crisis, we need ambitious targets and reliable indicators to accurately track trends measure conservation impact. In Canada, Living Planet Index (LPI) has been adapted produce a national indicator by both World Wildlife Fund-Canada (Canadian Index; C-LPI) Environment Climate Change Canada Species Index) provide insight into status of Canadian wildlife, eva...

skid resistance and road condition are common indices of road safety; therefore providing adequate skidding resistance will reduce the incidence of road accidents. the surface macrotexture has a large effect on the characteristics of road surface skidding, which is the focus of this research. during the study, the mean texture depth of the road surface was measured, in order to determine the co...

Wildfire increases the magnitude of runoff in catchments, leading to degradation ecosystems, risk infrastructure, and loss life. The Labor Day Fires 2020 provided an opportunity compare multiple large severe wildfires with objective determining potential changes hydrologic processes Oregon Cascades watersheds. Geographic information systems (GIS) were implemented determine total percentage burn...

As a regulator of ecological environment, Baiyangdian Wetland is in pivotal position constructing the blue-green space (BGS) Xiong’an New Area China. This study aims to reveal spatiotemporal changes BGS from 2016 2021. It uses Google Earth Engine (GEE) calculate NDVI and NDWI based on Sentinel-2 Satellite remote sensing data extracts by classification model driven NDWI. Moreover, land-use trans...

(Received: July 21, 2012; Accepted in Revised Form: July 5, 2013) Abstract: The principal concern of this study is to formulate the sub-pollution indices (sub-LPIs) and evaluate the individual and overall leachate pollutant index (LPI) of pilot scale landfill lysimeter at KUET campus, Bangladesh. To these endeavors, leachate samples from collection chamber of landfill lysimeter were sampling an...

Abstract To analyse and characterise land use-land cover (LULC) change, remote sensing (RS) data geographic information system (GIS) approaches are required. The landscape metrics also extensively used to explain the structure pattern of spatial landscape. This case study has been conducted in area Bhagirathi-Hugli River banks West Bengal. area’s satellite image from various periods (1989-2017)...
