Case-study - Generating climate relevant information for multiple impacted sectors

by Climate-KIC  (Jan. 23, 2015)

A lack of useful regional climate and climate impact information could threaten the sustainability and competitiveness of a number of key sectors. Thus, Climate Impact Expert System (CIES) develops an online web portal to make that information readily available. In-depth climate and climate impact consulting services based on the data and the ...

Custom functionality and integrative approaches for hydrological modelling tools for water resources planning and management

by IWA Publishing  (Jan. 16, 2015)

This paper outlines the application and usefulness of a software platform that enables hydrologists to develop custom functionality in a new hydrological modelling tool, eWater Source, designed for water resources planning and management. The flexible architecture of the software allows incorporation of third-party components as plug-ins to add ...

Streamflow and hydrogen ion interrelationships identified using data-based mechanistic modelling of high frequency observations through contiguous storms

by IWA Publishing  (Dec. 22, 2014)

With the aim of quantifying the purely hydrological control on fast water quality dynamics, a modelling approach was used to identify the structure (and dynamic response characteristics or DRCs) of the relationship between rainfall and hydrogen ion (H+) load, with reference to rainfall to streamflow response. Unlike most hydrochemistry ...

Effects of model segmentation approach on the performance and parameters of the Hydrological Simulation Program – Fortran (HSPF) models

by IWA Publishing  (Dec. 22, 2014)

Although models are one of the most powerful tools for watershed management, their effectiveness is limited by prediction uncertainties resulting from not only model input data but also spatial discretization. In this paper, Hydrological Simulation Program – Fortran (HSPF) models were constructed for the Linyi watershed according to three ...

Groundwater, flooding and hydrological functioning in the Findhorn floodplain, Scotland

by IWA Publishing  (Dec. 22, 2014)

A large floodplain of the River Findhorn, northeast Scotland, was investigated using hydrogeological and hydrochemical methods (including residence time indicators) to characterise groundwater/surface-water coupling and groundwater flooding. The study demonstrated widespread stratification within the floodplain: shallow (<8 mbgl) deposits ...

Modelling the hydrological impacts of rural land use change

by IWA Publishing  (Dec. 22, 2014)

The potential role of rural land use in mitigating flood risk and protecting water supplies continues to be of great interest to regulators and planners. The ability of hydrologists to quantify the impact of rural land use change on the water cycle is however limited and we are not able to provide consistently reliable evidence to support ...

Hydrological and environmental assessment of urban growth in a sub-tropical town in India

by IWA Publishing  (Dec. 15, 2014)

Roorkee, a sub-tropical urban town in India, has shown a rapid unplanned growth in the past. This paper presents the findings of a study of characteristics of urban soil, rainwater, and runoff emanating from different sources areas and the stormwater flows in the drains. Urban soil showed significant increase in the concentration of all ...

Modeling the hydrologic and economic efficacy of stormwater utility credit programs for US single family residences

by IWA Publishing  (Dec. 15, 2014)

As regulatory pressure to reduce the environmental impact of urban stormwater intensifies, US municipalities increasingly seek a dedicated source of funding for stormwater programs, such as a stormwater utility. In rare instances, single family residences are eligible for utility discounts for installing green infrastructure. This study examined ...

Metal Mixture Modeling Evaluation project: 2. Comparison of four modeling approaches

by John Wiley & Sons, Ltd.  (Nov. 24, 2014)

As part of the Metal Mixture Modeling Evaluation (MMME) project, models were developed by the National Institute of Advanced Industrial Science and Technology (Japan), the U.S. Geological Survey (USA), HDR׀HydroQual, Inc. (USA), and the Centre for Ecology and Hydrology (UK) to address the effects of metal mixtures on biological responses of ...
