  • Water management solutions minimize flood damage

    Human societies around the world have used timber as a building material for thousands of years. As wood is the only significant biological building material we are naturally inclined to believe that using wood in construction is good for the environment. As a matter of fact the environmental benefits of using timber are not straightforward: although it is a natural product, a large amount of ...

  • In the depths of the oceans, human activities are beginning to take their toll

    Once seen as too remote to harm, the deep sea is facing new pressures from mining, pollution, overfishing and more. Imagine sinking into the deepest parts of the Central Pacific Ocean, somewhere between Mexico and Hawaii. Watch as the water turns from clear to blue to dark blue to black. And then continue on for another 15,000 feet (4,600 meters) to the seafloor — roughly the ...

  • Environmental Impact does NOT equal risk

    Auditing the new ISO 14001:2015:  Environment Impacts does not equal Risk In recent transition audits, there has been one common misconception that I have seen repeated, and that is that environmental impacts are risks.  This is not correct.  Environmental impacts do not equal risk. Let’s start ...

  • Building Box Culverts with Articulated Cable Concrete Block Systems

    When you need to manage the flow of water in an area with streams, heavy rainfall or otherwise consistently wet conditions, the box culvert stands the test of time. Box culverts have been around for many years for a good reason: they can be excellent tools for directing and controlling water so it doesn’t cause erosion and interfere with roads, trails or other manmade structures that need ...

  • Get More Out of Water Resources Engineering Models

    by Venu Kandiah, PhD, P.E. Senior Water Resources Engineer The effort required to develop water resources engineering models can be significant. But once developed, in many instances the models are only evaluated for a limited, or a single set of conditions. The results and predictions obtained from these evaluations are the ones used in design, presented in reports and ...

  • Modelling the Thatcham Flood - Case Study

    Overview On 20th July 2007, an unusual storm swept west across England along the approximate line of the M4 motorway. Thatcham, a town in Berkshire, was one of the worst affected. Many towns in England flooded that month from the Humber to Tewksbury. In fact there were 200 major floods worldwide in 2007 affecting 180 million people. Some of these floods were caused by rainfalls much more ...

    The effort required to develop water resources engineering models can be significant. But once developed, in many instances the models are only evaluated for a limited, or a single set of conditions. The results and predictions obtained from these evaluations are the ones used in design, presented in reports and conveyed to decision makers and the public. This approach might serve ...

  • Innovative renewal strategies for optimized pipeline management

    Using risk-based data analysis and innovative renewal strategies, two US water systems show how utilities can avoid full pipeline replacement, reduce service interruptions, and save money. As this informative Opflow article discusses, by more precisely understanding the condition of buried infrastructure, water utilities can more effectively focus resources to prolong safety and increase ...

  • Decision sciences in the management of water resources: multi-criteria methods and game theory applied to the field of sanitation

    Due to the complexity of some managerial problems, especially those related to sanitation, academic studies have shown the need to use appropriate methods to assist in this type of decision. Within this context, this research aimed to provide a review of the literature from the field of decision sciences to the field of water resource management. It was identified in this study that the use of ...

  • Hydrochemical characterization of a river affected by acid mine drainage in the Iberian Pyrite Belt

    This paper addresses the modelling of the processes associated with acid mine drainage affecting the Trimpancho River basin, chosen for this purpose because of its location and paradigmatic hydrological, geological, mining and environmental contexts. By using physical-chemical indicators it is possible to define the contamination degree of the system from the perspective of an entire river ...

  • Application of long amplicon propidium monoazide-PCR to assess the effects of temperature and background microbiota on pathogens in river water

    The decay rates of enteric waterborne pathogens were evaluated following the introduction of Yersinia enterocolitica, Salmonella enterica, Campylobacter jejuni and Arcobacter butzleri into river water at different temperatures (5, 15 and 25°C) for a period of 28 days. To improve the accuracy of the results a molecular viability assay, long ...

  • In a Future of Extremes, Southeastern States Must Have Water Management Policies

    Introduction Climate change is expected to have an impact on every type of weather phenomenon that occurs on Earth.  The nature and magnitude of the impact varies with the location on the planet and the type of weather in question, and coupled climate-weather models, have different degrees of uncertainty about different types of weather (though these models are dramatically improving ...

  • Modelling energy costs for different operational strategies of a large water resource recovery facility

    The main objective of this paper is to demonstrate the importance of applying dynamic modelling and real energy prices on a full scale water resource recovery facility (WRRF) for the evaluation of control strategies in terms of energy costs with aeration. The Activated Sludge Model No. 1 (ASM1) was coupled with real energy pricing and a power consumption model and applied as a dynamic ...

  • Examining the effects of urban agglomeration polders on flood events in Qinhuai River basin, China with HEC-HMS model

    The urban agglomeration polders type of flood control pattern is a general flood control pattern in the eastern plain area and some of the secondary river basins in China. A HEC-HMS model of Qinhuai River basin based on the flood control pattern was established for simulating basin runoff, examining the impact of urban agglomeration polders on flood events, and estimating the effects of ...

  • Long-term impacts of deep-sea mineral mining

    A new international study has demonstrated that deep-sea nodule mining will cause long-lasting damage to deep-sea life. This study, led by scientists at the National Oceanography Centre (NOC), was the first to review all the available information on the impacts of small-scale sea-floor disturbances simulating mining activity. It found clear impacts on marine ecosystems from deep-sea nodule mining ...
