  • Rainfall and surface water resources of Rajasthan State, India

    The water resources in Rajasthan State are facing a crucial stage even after average/good rainfall. Temporal distributions as well as the spatial variability of rainfall within the state were investigated by applying an analysis of variance (ANOVA) test. The effect of change in catchment characteristics and anthropogenic activities on overland flow are also investigated in this paper by ...

  • FORUM–13: Competitive water use and its redistribution

    Adequate sources of water, surface and ground water have to be available to meet not only the current needs but also the future growth of a community or a region. This brief Forum outlines some examples which illustrate how the water redistribution issue has been handled in the past. It concludes that, despite expected political resistance and high project costs, mega water projects often prove ...

  • Augmentation of surface water sources from spatially distributed rainfall in Saudi Arabia

    This study investigated the rainfall patterns, spatial variability, surface runoff generation and dam requirements in the southwestern region of Saudi Arabia. The region was divided into four areas Asir, Jazan, Al-Baha and the Red Sea Coast. Surface runoff was estimated for eight scenarios considering the runoff coefficients of 0.05–0.70, resulting in 203–2,835 million cubic meters (MCM) of ...

  • Managing Great Lakes Water Levels Adaptively in Response to Changing Climate Conditions

    The Laurentian Great Lakes contain an abundance of fresh water, collectively representing approximately 20% of the fresh surface water available globally. Despite the enormity of this resource, water levels and flows in the Great Lakes are subject to fluctuations caused by changing climate conditions that have cascading impacts on the coastal ecosystem and the regional economy. Proactive ...

  • Planning and Economics

    Planning for Water Recycling In the face of limits on available surface water resources, and increasing vulnerability to drought and climate change, many water authorities are looking to diversify their sources of supply. Options to diversify supplies include groundwater sources, use of recycled water, or desalination of seawater. Recycled water is a good ...

  • Reclaimed water for the Tarragona petrochemical park

    The Camp de Tarragona Water Reuse Project is an emblematic example of how regional water scarcity can be overcome by considering reclaimed secondary effluent, which would otherwise be disposed of in the Mediterranean Sea, as an essential component of integrated water resources management. An advanced water reclamation plant (AWRP) was completed in 2011 to reclaim municipal secondary effluent ...

  • Improving water quality communications at beaches: input from stakeholders

    Objectives: Water quality communication practices vary widely and stakeholder input has not played a role in defining acceptable levels of risk. Although the 2012 Recreational Water Quality Criteria (RWQC) emphasize the importance of promptly notifying the public about hazardous conditions, little is known about the public's understanding of notifications, or about levels of risk deemed ...

Bend Subsidence District was created by the State and Regulations have been issued requiring all Public Water suppliers to decrease their groundwater withdrawal by 30 percent by 2013 and 60 percent by 2025. Each user must identify ...

  • Pesticide multiresidues in waters of the lower fraser valley, British Columbia, Canada. Part II. Groundwater

    Received for publication October 3, 2007. In Part I of this work we presented pesticide levels in the surface waters of the Lower Fraser Valley (LFV) region of British Columbia, Canada. In Part II pesticide levels in the groundwater of the LFV are presented. During the period 2003 to 2005 a study was conducted to determine the occurrence and spatial distribution of 78 pesticides in the ...

  • Managing the invisible : understanding and improving groundwater governance

    Groundwater is playing an increasingly important role in domestic, industrial and agricultural water supply. With the advent of the tube well and driven by the rapid growth of demand for agricultural and municipal water, annual global groundwater extraction has increased in recent decades from 100 km3 a year in 1950 to a current estimated use of about 800 km3 a year (Wada et al., 2010; Margat, ...

  • Verification of Wind-Driven Volatilization Models

    Abstract  Mass-transfer processes of paramount importance, such as reaeration and volatilization, occur at the air–water interface. Particularly, volatilization is intensively studied because it can be a relevant removal process for toxic contaminants from flowing and standing surface waters. The paper provides a comparison among predictive equations available from literature for standing ...
