the groundwater resources of the urmia plain have been under intensive tension for the last recent years. this has caused the production and observation wells to become dry and in some local places well deepening to take place. in some other locations, the groundwater level is high and there is a danger of local water logging condition along with its associated drainage work. for the settlement...
Implementation of aquifer storage recovery (ASR) for water resource management in Florida is impeded by arsenic mobilization. Arsenic, released by pyrite oxidation during the recharge phase, sometimes results in groundwater concentrations that exceed the 10 µg/L criterion defined in the Safe Drinking Water Act. ASR was proposed as a major storage component for the Comprehensive Everglades Resto...
Water loss and nutrients loss are one of the important signs of natural resource degradation in the catchments. The amount of loss of these resources is affected by several factors including the characteristics of rainfall. In this study, the data of stream discharge (Q), total dissolve solids (TDS), and total nutrient loss ratio (NR) along with rainfall characteristics were analyzed for the ev...
Unpaved resource roads have the potential to produce large amounts of sediment and can negatively impact water quality and aquatic ecology. In order to better understand the dominant controls on sediment generation from unpaved resource roads, we did 23 large-scale rainfall simulation experiments on a road section in the Honna Watershed, Haida Gwaii, British Columbia, Canada. The experiments we...
Although surface water is the most accessible type of resource for industrial and agricultural use, it vulnerable to depletion in quantity quality [...]
The severe drought in the western United States in 1976-78 brought the problems of allocating extremely limited water resources to the attention of agriculturalists and urbanites alike. Greatly reduced surface water supplies exacerbated the already critical pressure on remaining groundwater stocks in the same areas. The chronic overdraft of many western states groundwater basins can be attribut...
Watershed educational and informational efforts have largely neglected to inform one important group of decision-makers: local government officials. The Internet Watershed Educational Tool (InterWET) was developed to help inform local officials about water resources, using as a case study the Spring Creek Watershed in central Pennsylvania. Utilizing the “microworlds” concept, InterWET consists ...
[1] Water trade and the establishment of water markets continue to gain popularity among legislators as a vehicle for progressing the reform of the water resources sector in Australia. This has manifested itself at the most recent meeting of the Council of Australian Governments, where a range of changes to address the declining health of inland rivers included the strengthening of water proper...
