The Rio Salado Environmental Restoration Project (Project) has been 40 years in the making and is the first of its kind in the desert southwest. It has become the benchmark for future river restoration Projects. The Project restores a 5-mile section of the Salt River (Rio Salado) that goes through the very core of the City of Phoenix. The Salt River provides essential 100-year flood protection for the City of Phoenix. The Project changes a dry riverbed eyesore of debris and gravel pits back into restored native wetlands and riparian habitats with recreational and educational uses while maintaining the essential flood control. It also revitalizes the central city area.
Florida’s Kissimmee River once flowed freely. Fish, birds and other wildlife dwelled in the wetlands it fed. But in the 1960s, spurred by public outrage over flooding, the U.S. Army Corps of Engineers straightened the winding waterway and turned it into a drainage canal.
Flip forward a few decades and the river is returning — at least in part. The U.S. Army Corps of Engineers has partnered with the South Florida Water Management District on the Kissimmee River Restoration Project, aiming to restore a...
An integrated approach to risk assessment that can pose significant challenges to mitigation and adaptation at the local or regional levels in the context of climate change was developed. First, a conceptual framework for flood risk analysis was developed based on the hydrologic hazard and the socioeconomic vulnerability of a region. Second, weighting factors for each indicator were estimated using the modified Delphi approach based on the results of a survey of an expert group. Third, geographic information...
Short video produced by Wetlands International - European Association and the Iberian Centre for River Restoration (CIREF) to illustrate the need for river restoration, the benefits it brings and the necessary factors for its success.
A methodology for indexing river environmental condition was developed and applied to 269 subsections of national rivers located in the Republic of Korea, based on a river management perspective. The resulting index has been called the River Environment Index (REI). To develop the methodology, a total of 32 factors related to a river's environment were initially investigated, from which 16 were chosen based on their measurability, predictability, measurement regularity and obtainability. Then, using the...
Continuing degradation of river ecosystems and environmental disruption are widespread in Chinese metropolitan areas. The study on the residents' preference for river ecosystem restoration is an essential part of assessing the environmental benefit and cost for policies implementation. A contingent valuation method is applied to estimate the public demand for urban river restoration in Hangzhou and Nanjing of the Yangtze River Delta, China. By employing an interval model, it was estimated the average individual's...
