Background: Using natural methods such as constructed wetland is one of the methods for municipal wastewater treatment that has the capacity of reducing costs of treatment and improving environment. The purpose of this study is to determine the efficacy of sub-surface constructed wetland in wastewater treatment in Yazd. Methods: This is an experimental study aimed of to determine the effica...
Observations of short-circuiting flow paths within a free-surface wetland in Augusta, Georgia, U.S.A
Velocity heterogeneity is characteristic of wetland systems and results in some influent water remaining in the wetland for less than the expected residence time on the basis of volume and flow rate. This phenomenon, known as short-circuiting, alters the distribution of the chemical and biological transformations that occur within the wetland. Field observations in a 1.5-km2 constructed treatme...
Abstract. Excess nutrients from agricultural settings contribute to surface water and groundwater impairment. Constructed wetlands have been widely used for quality protection in various systems. We a synthesis approach document the performance of constructed nutrient removal range landscapes geographic regions with following objectives: (1) review current use applications, (2) summarize effici...
Sustainable water management has become an urgent challenge due to irregular availability patterns and quality issues. The effect of climate change exacerbates this phenomenon in water-scarce areas, such as the Mediterranean region, stimulating implementation solutions aiming mitigate or improve environmental, social, economic conditions. A novel solution inspired by nature, technology-oriented...
Freshwater coastal prairie wetlands once covered large expanses of the Houston-Galveston landscape. A complex wetland matrix of mima mounds and low wetland basins known as prairie potholes provided important ecological services including habitat, lood control and water cleansing. Many of these areas were land leveled for agricultural and development purposes, erasing these features from the coa...
