European waters - assessment of status and pressures
EEA 2012 'State of Europe's water' assessments 2012 is the European year of water in which the European Commission published its 'Blueprint to safeguard Europe's waters' (referred to hereafter as the Blueprint) comprising reviews of the Water Framework Directive (WFD) (2000/60/EC), water scarcity and drought and adaptation to climate change policies. To accompany and inform the blueprint, ...

Installing Continuous Multi-Chamber Tubing Using Sonic Drilling
As a geologist, core is the first thing that comes to mind when talking about sonic drilling— continuous, near complete core recovery through almost any lithology. Sand to silt transitions can be logged on a centimeter scale if desired. Geologic contacts can be mapped with accuracy of less than one foot. In an environmental ground water assessment, it seems an awful shame to collect ...

A comparative study of single factor and multivariate statistical methods for surface water quality assessment
Water quality assessment is an essential part of water resources management. Different methods, including the single factor (SF) method and multivariate analysis, employed in assessing water quality can give different results. In this study, SF methods and multivariate analysis – including discriminant analysis (DA) and the distance function model (DFM) – were used to assess the ...

Water quality assessment of Malad Creek, Mumbai, India: an impact of sewage and tidal water
The aim of the study was to carry out water quality assessment and to identify sources responsible for deterioration of quality in the Malad creek, Mumbai, India. Creek receives sewage and wastewater from various drains and partially treated effluent from Malad and Versova treatment facilities. To assess the water quality, sampling locations were identified in the creek based on discharges of ...

Modelling streamflow response to climate change for the Kyeamba Creek catchment of south eastern Australia
This study predicts the probable impacts of climate change on the streamflow of Kyeamba Creek catchment of south eastern Australia. Three climate scenarios (B1, A1B and A2) and the average of four general circulation models (CNRM-CM3, CSIRO-MK3.5, ECHam5 and MIROC3.2) were used to simulate the streamflow for three future periods (2030, 2050 and 2090). Soil and Water Assessment Tool (SWAT) was ...

Multi-variable sensitivity and identifiability analysis for a complex environmental model in view of integrated water quantity and water quality modeling
Environmental models are often over-parameterized. A sensitivity analysis can identify influential model parameters for, e.g. the parameter estimation process, model development, research prioritization and so on. This paper presents the results of an extensive study of the Latin-Hypercube–One-factor-At-a-Time (LH-OAT) procedure applied to the Soil and Water Assessment Tool (SWAT). The LH-OAT is ...

Sudan - Preliminary water information assessment study : final report
This report contains the findings of the Southern Sudan Preliminary Water Information Assessment Study prepared for the Ministry of Water Resources and Irrigation (MWRI) of the Government of Southern Sudan (GoSS), under Technical Assistance funded by the World Bank (WB). The main objective of the study was to prepare a stocktaking of the water sector in Southern Sudan, prepare terms of reference ...

Research on raw water quality assessment oriented to drinking water treatment based on the SVM model
Raw water quality variation has a great effect on drinking water treatment. To improve the adaptivity of drinking water treatment and stabilize the quality of treated water, a raw water quality assessment method, which is based upon the support vector machine (SVM), is developed in this study. Compared to existing raw water quality assessment methods, the assessment method studied herein is ...

Influence of human activities and climate variability on green and blue water provision in the Heihe River Basin, NW China
Human activities and climate simultaneously affect water cycling and provision. Here, we study the impacts of climate variability and human activities on green and blue water provision (or the flows of both green water and blue water) in the inland Heihe River Basin as simulated by the Soil and Water Assessment Tool (SWAT). The results show that total green and blue water flow varied ...

Application of the biotic ligand model to predict copper acute toxicity to Medaka fish in typical Chinese rivers
LA50, the Lethal Accumulation of Cu on the Medaka fish (Oryzias latipes) gills that results in 50% mortality during a toxicological exposure (96 hours) in synthetic water was assessed by use of the biotic ligand model (BLM). The LA50 was employed to predict the 96 h Cu toxicity (LC50) to this fish in different natural surface waters in China. The LC50 values were predicted with errors of no more ...

Climate change and Water Harvesting possibilities in arid regions
In arid and semiarid regions, water resources are scarce and need climate change impact assessment for water conservation after each storm rainfall as rainfall harvesting in urban areas and runoff harvesting in rural areas. It is the main purpose of this paper to present necessary Water Harvesting (WH) preparation principles by considering simple climate change models for the Arabian Peninsula ...

Impact of the Three Gorges reservoir operation on downstream ecological water requirements
With population increase and economic growth, the flow regime of the Yangtze River has been altered to some extent by human activities, particularly dam construction. Dam-induced alterations in the flow regime of the Yangtze River will unavoidably influence water allocation among different water users and instream ecological water requirements may not be guaranteed during some months, ...

Reframing risk: a risk pathway method for identifying improvement through control and threat analysis
This paper describes the benefits of applying a risk pathway method as an evidence-based whole of supply chain risk assessment approach in the delivery of efficient and effective quality management frameworks for water. It presents a new approach for assessing water service provision risk that considers the chronology of the series of causes, impacts and consequences to business outcomes ...

Durability of hybrid FRP reinforcing bars in concrete structures exposed to marine environments
To solve the brittle failure of existing FRP rebar, we developed hybrid FRP rebar that has more than 3% strain and plastic deformation like a steel reinforcement. So, the developed hybrid FRP rebar has emerged as one of the most promising and affordable solution to the brittle failure problem of existing FRP rebar in concrete structures. In this study, the durability of hybrid FRP rebar exposed ...

Assessment levels for water quality in WA
The Government of Western Australia through its Department of Water and Environmental Regulation has the authority and mandate to measure the quality of groundwater and surface water across the country. The primary objective of carrying out an assessment of water is to ensure that the water is clean and safe for drinking and other purposes. Water assessment is done by assessing three classes of ...

Aqueduct Informs AU Optronics Corporate Water Strategy
The World Resources Institute (WRI) Markets and Enterprise Program conducted a global geographic water risk assessment with multinational electronics manufacturer AU Optronics (AUO). WRI plotted AUO’s fabrication plants worldwide on global maps of water risk using Aqueduct’s Water Risk Atlas. This assessment aims to identify which AUO fabrication plants are located in areas and draw ...

Estimating water yield response to land use in the Namoi catchment of the Murray-Darling Basin, Australia
The Namoi catchment is an intensively developed irrigation area in the Murray-Darling Basin (MDB) and has a mixture of land use types including cropping, pasture and forests. It is yet to implement an integrated groundwater and surface water management system. The Soil Water Assessment Tool was applied for the Namoi to estimate surface runoff and groundwater contribution to streams. SWAT ...
