This study examines the sediment retention in Wadi Baysh using Revised Universal Soil Loss Equation (RUSLE) and TerrSet models, accompanied by integrated remote sensing Geographic Information System (GIS) techniques. The contribution of this is mainly associated with application high resolution datasets to precisely estimate sediments load, which provide useful information operate dams improve operational efficiency dams. Advanced Land Observing Satellite (ALOS) Phased Array type L-band...

Subcontracting on construction projects is a common and well-established practice. Contractors enlist the services of subcontractors to achieve certain objectives, including obtaining cost reductions, securing access specialized services, risk sharing. Nonetheless, subcontracting project can introduce associated problems that affect management quality. This research explored exclusively practices in industry Pakistan, identified main problem areas, examined overall satisfaction with quality...

Water is essential for life, agriculture, and industrialization; however, a rapid increase in population constantly causing water scarcity pollution Pakistan. Mining activities produce the potential toxic element (PTE) accumulation, which lead to unnatural enrichment, ecological pollution, environmental degradation. The resources impeded by PTEs cause serious abnormalities through dermal contact, inhalation, digestion. induced anthropogenic are well-known causes of contamination resources....

Me--asurement of Supply Chain (SC) performance with regards to key practices SC paradigms is the area which under research. Presently there are no guidance or set rules we can measure performance. The lack clarity and comparability concerns in this creates misunderstanding makes it more difficult formulate a clear strategy. aim research identify antecedents existing paradigm's practices, as well for measurement conceptual framework. Based on research, new sustainable framework proposed...

In building construction, discrepancies frequently occur between design and construction in relation to architectural details, structural materials, quality of construction.The objective this paper is identify the major causes construction.A questionnaire was utilised that contained 65 potential classified into 4 categories: design, tendering, overall project.The data from Pakistan response rate excellent (80.6%).The collected analysed important were identified.The results indicate provision...

The construction industry consumes a large part of raw material and global energy, produces huge amount solid waste.It is established that waste generated by processes has significant negative impact on the economy environment.Effective management helps in reducing quantity wastes making substantial contribution towards sustainable development cost control.Based benchmarking approach, this research quantifies wastage its causes different types building projects.In diagnostic survey, 38...

Purpose The purpose of this research is to quantify the effect stakeholder conflicts on project constraints in construction industry using ordinal regression analysis. For purpose, most significant and factors that cause found literature are measured. Design/methodology/approach Factors causing extracted through a content analysis published literature. Further, questionnaire survey conducted involving 170 professionals assess constraints. Finally, obtain more objective assessment,...

This study evaluates the spatial and temporal performance of Climate Hazard Group InfraRed Precipitation Satellite (CHIRPS) against Tropical Rainfall Measuring Mission (TRMM) Multi-Satellite Analysis (TMPA) 3B42/3B43 v. 7 Global Measurement (GPM)-based Integrated Retrievals for GPM (IMERG V06), from 2000 to 2013. Several statistical metrics were used assess CHIRPS over Indus Basin, its hydrological utility is also assessed using Soil Water Assessment Tool (SWAT). The Gilgit Soan basins...

Climatic variability and the quantification of climate change impacts on hydrological parameters are persistently uncertain. Remote sensing aids valuable information to streamflow estimations parameter projections. However, few studies have been implemented using remote CMIP6 data embedded with modeling. This research studied how changing influences hydro-climatic based earth system models that participated in sixth phase Coupled Model Intercomparison Project (CMIP6). GRACE...

Abstract This paper investigates a range of water savings options at irrigation system level and ranks these according to the potential each option economic return in terms saved (ML – megalitres) for dollar invested. Most work was conducted on large‐area farms Murrumbidgee Irrigation Area (MIA) Coleambally (CIA) River catchment, New South Wales, Australia. Field‐based on‐farm scenarios analysed ranged from 0.1 ML ha −1 up 3.9 (10–390 mm). As capital can be limiting resource farmers, that...

Purpose The formal application of project risk management (PRM) in green building projects is still an emergent part management. purpose this paper to provide a conceptual PRM framework that increases the probability success by minimizing unexpected events. Design/methodology/approach This interprets related literature and uses opinion experts. It exposes some pertinent elements needed for structuring suggests mitigation actions high-ranked risks. also performs ex-post analysis on case study...

Almost all construction projects face delays resulting in extension of time (EOT) or liquidated damages, depending upon which the two parties absorbs responsibility as per terms contract. A number factors influence realistic assessment EOT claims, along with level awareness and technical support. The industry Pakistan, operates a rather traditional outdated style, has never been assessed on such critical contract management aspects. It resulted into various disputes, court cases, bad blood...
