  • A fuzzy quality index for the environmental assessment of a restored wetland

    This paper describes the feasibility study for the restoration of agricultural land with a tendency to become waterlogged into a natural wetland, conceived to mitigate floods and to remove nutrients from the water drained from the cultivated plots. The wetland model, developed in aquatox, includes the nutrient dynamics both in the water and in the sediment, and the vegetation that is expected to ...

  • Restoring environmental flow: buy-back costs and pollution-dilution as a compliance with water quality standards

    An important challenge for policymakers worldwide is how to respond to increasing water demand while still assuring healthy ecosystems via ‘environmental flows’. In the case of Chile, increasing water demand and frequent water supply shortages are putting pressure on ecosystem water requirements. On the other hand, new environmental regulations are being implemented to improve the ...

  • Design of a channel and floodplain corridor to restore aquatic habitat, geomorphic function and water quality in an urbanized and regulated watershed

    The City of Cupertino, California has proposed the establishment of the Stevens Creek Corridor Park. At the park site, Stevens Creek has an incised alluvial channel. Bed morphology is typified by riffles and pools with some external forcing by in-stream large woody material. The channel has been subjected to hydromodification and general anthropogenic disturbance due to upstream reservoir ...

  • The potential to improve water quality in the middle Rio Grande through effective wetland restoration

    The Rio Grande, which forms the United States—Mexico border for much of its course, receives diverse pollutants from both urban and agricultural areas, most notably in the sister cities of El Paso (TX, USA)—Ciudad Juárez (CHI, Mexico). This study aimed to describe regional trends in water quality in waters near the El Paso–Ciudad Juárez metroplex and to examine the potential for water quality ...

  • Fawn River Restoration, Restoring one of Indiana`s Most Pristine Rivers

    In 1998, approximately 100,000 CY of sediment was discharged to a 5-mile section of Fawn River, in Steuben County, Indiana as the result of a rapid draw down of an upstream reservoir (the “Event”). Prior to 1998, Fawn River below the Orland dam (“lower Fawn”) was recognized as one of the best-preserved sections of river in the State of Indiana. The Fawn had a deep swift ...

  • Handbook for developing watershed plans to restore and protect our waters

    This handbook provides information on developing and implementing watershed management plans that help to restore and protect water quality. A watershed is the area of land that contributes runoff to a lake, river, stream, wetland, estuary, or bay. A watershed management plan defines and addresses existing or future water quality problems from both point sources and nonpoint sources of ...

  • Constructed wetlands as an alternative restoration measure for shallow lakes

    This paper deals with the consequences of cultural eutrophication and unconventional solutions for shallow lake restoration. Cultural eutrophication is the primary problem that affects especially shallow lakes, due to their physical characteristics (e.g. shallow depth, lack of stratification). Palic Lake, a very shallow Pannonian lake, received treated municipal wastewaters coming from the ...

  • Remote monitors track river restoration success

    The Norfolk Rivers Trust has installed a remote river monitoring station that has been tracking water quality and flow before and after river restoration work at an area of ecological importance on the River Nar. Rising in chalk hills to the east of the village of Tittleshall, the river flows south for 2.5 km until it reaches Mileham, then predominately west for 39.5 km through the villages of ...


  • Chicago botanic garden restoration, Chicago, Illinois

    One of the most significant features of the Chicago Botanic Garden (CBG) is its con-structed 24 ha (59 acre) lake system cre-ated in 1967. Since its construction, active bank erosion has resulted in a shoreline that lacks visual appeal and is devoid of aquatic habitat. In fact, the 10.3 km (6.5 mi) of eroded shoreline has lead to the loss of over 0.8 ha (2 acres) of land in the past 30 years. ...

  • Post Construction Cleanup and Restoration with Gas Pressure Washers

    After the completion of construction, the building or structure has to be thoroughly cleaned, removing excess grime and dust from walls, floors, sidewalks, and similar structures. One way to achieve fast and efficient cleaning is through the use of a powerful gas pressure washer. You may use an electric pressure washer as well, but most contractors use a gas pressure washer as these machines do ...

  • Impacts of aquatic macrophytes configuration modes on water quality

    Constructed wetland technology is regarded as an important ecological restoration technology and used widely in sewage disposal. In order to give them a wider scope of application and to improve their performance in water restoration, the current experiment was designed. Four aquatic macrophytes (dwarf cattail (TM), yellow-flowered iris (WI), water shallot (ST) and watermifoil (MS)) were picked ...

  • Taiwan: Water quality key to success in eel farming

    A notable Taiwanese scholar discovered the key to growing eel in Taiwan: good water quality. Only Japan had been capable of raising eel in Asia. He reported, 'The number one source of pond pollution is the bottom of the ponds where animal wastes and left-over feed accummulate and deplete oxygen.' This scholar raises Anguilla japonica eels at his research institute’s 2 hectare farm at stocking ...

  • Using watershed function as the leading indicator for water quality

    Diffuse nonpoint source (NPS) pollutants, such as sediment, nitrogen, phosphorus, and pathogens, have become the primary cause of water quality impairments in the United States of America. Resource management agencies in the USA are expanding the use of tools for the assessment of ecosystem function in water quality programs to control NPS pollution to meet US Clean Water Act objectives. ...
