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 ...

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 ...

Integrating GIS and Groundwater Modeling Technologies for SWAPP Development
Groundwater Modeling and GIS Technologies: Powerful Tools for Data Integration and Analysis Groundwater modeling and Geographic Information System (GIS) technologies are useful tools for developing a Source Water Assessment and Protection Plan (SWAPP) to assist planners in protecting groundwater ...

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 ...

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 ...

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 ...

An interdisciplinary approach to the assessment of water recycling technology options
Whilst work on the development of engineering options for water recycling has continued apace over the last decade, less attention has been paid to the problem of selecting appropriate technologies for particular applications. This paper firstly reviews the motivations for a cross-disciplinary approach to technology selection in this context, highlighting the process of translating research ...

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 ...

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 ...

Incorporating parameter uncertainty into Quantitative Microbial Risk Assessment (QMRA)
Modern statistical models and computational methods can now incorporate uncertainty of the parameters used in Quantitative Microbial Risk Assessments (QMRA). Many QMRAs use Monte Carlo methods, but work from fixed estimates for means, variances and other parameters. We illustrate the ease of estimating all parameters contemporaneously with the risk assessment, incorporating all the parameter ...

Development of a water quality assessment model: a water quality assessment model based on watershed characteristics by non-linear regression
Here, a water quality assessment model (WQAM) is developed by non-linear regression as an alternative to physical watershed modeling in South Korea. Three cases and 10 scenarios are applied and reviewed to determine the most appropriate WQAM. The three cases are: (1) the area size allocation of sub-watersheds, (2) the watershed imperviousness ratio, and (3) the combination of the area size and ...

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 ...

Short‐term macroinvertebrate recruitment and sediment accumulation: A novel field chamber approach
Stream‐deposited sediment is one of the major stressors affecting stream biota. Several methods exist to quantify stream sediment embeddedness, but they are relatively qualitative and operationally defined. The authors developed a short‐term in situ embeddedness chamber method to measure aquatic insect recruitment and associated sediment accumulation in a more quantitative, better replicated ...

Modeling Phosphorus in the lake Allatoona watershed using swat: I. developing Phosphorus parameter values
Lake Allatoona is a large reservoir north of Atlanta, GA, that drains an area of about 2870 km2 scheduled for a phosphorus (P) total maximum daily load (TMDL). The Soil and Water Assessment Tool (SWAT) model has been widely used for watershed-scale modeling of P, but there is little guidance on how to estimate P-related parameters, especially those related to in-stream P processes. In this paper, ...

Assessing the impacts of climate change on water resources in the Srepok watershed, Central Highland of Vietnam
The Srepok watershed in the Central Highland of Vietnam plays an important role in the economic development of the region. Any harmful effects of climate change on natural resources may cause difficulties for social and economic development in this area. The present study aims to predict and evaluate changes of water resources in the Srepok watershed under the impact of climate change ...

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 ...

Assessing the sensitivity of SWAT physical parameters to potential evapotranspiration estimation methods over a coastal plain watershed in the southeastern United States
One of the key inputs of a hydrologic budget is the potential evapotranspiration (PET), which represents the hypothetical upper limit to evapotranspirative water losses. However, different mathematical formulas proposed for defining PET often produce inconsistent results and challenge hydrological estimation. The objective of this study is to investigate the effects of the Priestley–Taylor ...
