“…Additional information beyond the radiometric response provided with optical satellites can be extracted from SAR data to help detect flooded areas [47,48] and classify wetlands [35,48], based on hydrologic features and surface structure. In a single-channel SAR system both the transmitted and received energy from the satellite are either horizontally (H) or vertically (V) polarized.…”

“…This allows the user to decompose the SAR backscatter being returned from the objects being sensed into four common scattering types: (1) specular scattering (no return to the SAR), which occurs from smoother surfaces such as calm water or bare soil; (2) rough scattering, which results when there is a single bounce return to the SAR from surfaces such as small shrubs or rough water; (3) volume scattering, which is when the signal is backscattered in multiple directions from features such as vegetation canopies; and (4) double-bounce or dihedral scattering, which results when two smooth surfaces create a right angle that deflects the incoming radar signal off both surfaces such that most of the energy is returned to the sensor. This latter scattering case typically occurs when vertical emergent vegetation is surrounded by a visible, smooth water surface [32,[47][48][49][50][51]. Flooded vegetation can also have a combination of double-bounce and volume backscattering [50,51].…”

Abstract:Wetlands are an important natural resource that requires monitoring. A key step in environmental monitoring is to map the locations and characteristics of the resource to better enable assessment of change over time. Synthetic Aperture Radar (SAR) systems are helpful in this way for wetland resources because their data can be used to map and monitor changes in surface water extent, saturated soils, flooded vegetation, and changes in wetland vegetation cover. We review a few techniques to demonstrate SAR capabilities for wetland monitoring, including the commonly used method of grey-level thresholding for mapping surface water and highlighting changes in extent, and approaches for polarimetric decompositions to map flooded vegetation and changes from one class of land cover to another. We use the Curvelet-based change detection and the Wishart-Chernoff Distance approaches to show how they substantially improve mapping of flooded vegetation and flagging areas of change, respectively. We recommend that the increasing availability SAR data and the proven ability of these data to map various components of wetlands mean SAR should be considered as a critical component of a wetland monitoring system.

“…For hydrological mod-ellers, an ideal approach is one that overcomes the need for often time-intensive topographic surveys and that is more practical for use in models at varying scales and locations. Previous studies have set about this by defining statistical relationships between surface area and volume for wetlands of specific physiographic regions (Gleason et al, 2007;Hubbard, 1982;Lane and D'Amico, 2010;Wiens, 2001). Such approaches have been found useful for modelling entire watersheds (Gleason et al, 2007), but limited for estimating storage in individual wetlands because depth and basin morphometry (i.e.…”

Abstract. Beaver ponds are surface-water features that are transient through space and time. Such qualities complicate the inclusion of beaver ponds in local and regional water balances, and in hydrological models, as reliable estimates of surface-water storage are difficult to acquire without time-and labour-intensive topographic surveys. A simpler approach to overcome this challenge is needed, given the abundance of the beaver ponds in North America, Eurasia, and southern South America. We investigated whether simple morphometric characteristics derived from readily available aerial imagery or quickly measured field attributes of beaver ponds can be used to approximate surface-water storage among the range of environmental settings in which beaver ponds are found. Studied were a total of 40 beaver ponds from four different sites in North and South America. The simplified volume-area-depth (V-A-h) approach, originally developed for prairie potholes, was tested. With only two measurements of pond depth and corresponding surface area, this method estimated surface-water storage in beaver ponds within 5 % on average. Beaver pond morphometry was characterized by a median basin coefficient of 0.91, and dam length and pond surface area were strongly correlated with beaver pond storage capacity, regardless of geographic setting. These attributes provide a means for coarsely estimating surface-water storage capacity in beaver ponds. Overall, this research demonstrates that reliable estimates of surfacewater storage in beaver ponds only requires simple measurements derived from aerial imagery and/or brief visits to the field. Future research efforts should be directed at incorporating these simple methods into both broader beaver-related tools and catchment-scale hydrological models.

“…Low intensity management to protect soil recharge and storage functions, and best management practices that protect embedded wetlands (FDACS 2008), result in landscapes that persist in their capacity to retain rainfall. This has particularly important implications with increased incidence of extreme events (floods and droughts) since those storages serve the multiple roles of retaining floodwaters under high rainfall conditions (Lane and D'Amico 2010), attenuating downstream risks, and also sustaining flow to streams during drier periods (McLaughlin et al 2014).…”

Key Messages• Production forestry provides substantial benefits to the state of Florida, including the provision of ecosystem services, such as regulation of water quantity and quality, provision of wildlife habitat and carbon sequestration, and supporting 80,000 jobs and $16.34 billion/year in economic activity.• Climate through the end of the century in the production forestry regions of northern Florida and southern Georgia is predicted to warm from 1.5 °C to almost 3.5 °C, with small increases in annual precipitation, and elevated atmospheric CO 2 concentration. Models predict that these changes will result in substantial increases in potential loblolly pine and slash pine plantation productivity, ranging from 5-35% depending on emissions scenario, species, and location.• Forestry is unique in that it is one of the few industries that sequesters more carbon than it emits. There are opportunities to increase carbon sequestration for mitigation of atmospheric CO 2 through retention or expansion of forested areas, altered forest management, and the use of woody biomass for power generation in place of fossil fuels.• The frequency and intensity of abiotic disturbances, such as wildfire and windstorms, are likely to be affected by climate change; but predictions remain uncertain about the magnitude of change and their effects on the forest resource.• Research is underway to better understand how native forest pests and pathosystems may respond to changing climate. The movement of pests or pathogens into previously nonimpacted areas is of particular concern.• Plantation forests have been a vital part of protecting regional water quantity and quality, and they will continue to be essential features of healthy, productive landscapes as climate changes and the potential for adverse climate impacts on water resources increases.'• The key to adapting forest management to changing climate will be the considered application of silvicultural tools, such as competition control, density and fertility management, and proper choice of species for each site. Keeping abreast of research advances related to these tools will be increasingly important for forest managers as climate conditions change.• There are several viable policy options for harnessing forests to mitigate climate change and increasing forest resilience and adaptation to climate change. However, since 71% of Florida's forests are privately owned, policy options must align well with landowner needs to have adequate impact. Broadly speaking, policies that improve market conditions, reduce burdens (regulatory and economic), and increase economic sustainability for forest landowners would help protect Florida's existing forests and the benefits they provide, and would encourage investment in reforestation of existing forestland and planting new forests on previously unforested land.
