Midwest by converting upland and wetland habitats to crops and pastures, simultaneously changing hydrologic conditions and water quality, and threatening the region’s biodiversity (Table 1). Where corn is the dominant crop (in Iowa, Illinois, and Indiana, in particular), extensive networks of perforated pipes and drainage ditches were installed to drain wetlands. As a result, surface and ground...

To provide scientific basis for utilizing wetland resources, the drought conditions of different types were evaluated in Yellow River Delta. Based on wetlands classification map, difference water and heat flux was studied, as well wetlands. The relationship between retrieved land surface temperature (LST) evapotranspiration (ET) analyzed through two section profiles directions using Geographic ...

Wetland cities were proposed by the International Convention Organization for protection of urban wetlands. Few studies have performed land cover classifications internationally recognized wetland or explored what contribution classification results can make to establishment additional date. Based on Sentinel-1 and 2 data, this study used a 10-fold random forest method classify first six in Chi...

Concern over historic wetlands loss led to a national goal of no net loss (NNL) of wetlands acres and their environmental services. In support of the NNL goal, the US Army Corps of Engineers (Corps), under authority granted by Section 404 of the Clean Water Act, reviews permits to discharge fill material into wetlands. A permit review process called sequencing requires a permit applicant (permi...

Natural wetlands, occupying 3.8% of China's land and providing 54.9% of ecosystem services, are unevenly distributed among eight wetland regions. Natural wetlands in China suffered great loss and degradation (e.g., 23.0% freshwater swamps, 51.2% costal wetlands) because of the wetland reclamation during China's long history of civilization, and the population pressure and the misguided policies...

Abstract. Wetlands, often called the “kidneys of earth”, play an important role in maintaining ecological balance, conserving water resources, replenishing groundwater and controlling soil erosion. Wetland mapping is very challenging because its complicated temporal dynamics large spatial spectral heterogeneity. An accurate global 30 m wetland dataset that can simultaneously cover inland coasta...

Ž . A wide range of local, state, federal, and private programs are available to support the national USA policy of wetland ‘No Net Loss’. Implementation of programs, however, has resulted in the continued loss of natural wetlands on the premise that restored or created wetlands will replace the functions and values lost by destruction of natural wetlands. What are the ecological implications a...
