“…The list of optical river mapping applications can be extended if one includes work based on coarse resolution satellite imagery, measurement of parameters outside the low flow channel or topics receiving relatively little research. Notable applications that fit these more general criteria include forecasting and detection of ice breakup on large rivers (Gatto, 1990;Pavelsky et al, 2004;Morse and Hicks, 2005), flood detection and monitoring (Barton and Bathols, 1989;Kishi et al, 2001;Brakenridge et al, 2005;Ip et al, 2006), detection of levee slides (Hossain et al, 2006), estimating erosion and deposition (Brasington et al, 2003;, mapping general habitat types such as standing water and forest (Novo et al, 1997), measuring suspended chlorophyll (Karaska, 2004) and mapping derived variables such as stream power (Jordan and Fonstad, 2005).…”

At watershed extents, our understanding of river form, process and function is largely based on locally intensive mapping of river reaches, or on spatially extensive but low density data scattered throughout a watershed (e.g. cross sections). The net effect has been to characterize streams as discontinuous systems. Recent advances in optical remote sensing of rivers indicate that it should now be possible to generate accurate and continuous maps of in‐stream habitats, depths, algae, wood, stream power and other features at sub‐meter resolutions across entire watersheds so long as the water is clear and the aerial view is unobstructed. Such maps would transform river science and management by providing improved data, better models and explanation, and enhanced applications. Obstacles to achieving this vision include variations in optics associated with shadows, water clarity, variable substrates and target–sun angle geometry. Logistical obstacles are primarily due to the reliance of existing ground validation procedures on time‐of‐flight field measurements, which are impossible to accomplish at watershed extents, particularly in large and difficult to access river basins. Philosophical issues must also be addressed that relate to the expectations around accuracy assessment, the need for and utility of physically based models to evaluate remote sensing results and the ethics of revealing information about river resources at fine spatial resolutions. Despite these obstacles and issues, catchment extent remote river mapping is now feasible, as is demonstrated by a proof‐of‐concept example for the Nueces River, Texas, and examples of how different image types (radar, lidar, thermal) could be merged with optical imagery. The greatest obstacle to development and implementation of more remote sensing, catchment scale ‘river observatories’ is the absence of broadly based funding initiatives to support collaborative research by multiple investigators in different river settings.

“…Several evolving lines of research are also worth tracking depending on management needs. Forecasting and detection of ice breakup on large rivers is receiving increased attention (Pavelsky et al, 2004;Morse andHicks, 2005, Kääb andProwse, 2011). This application has the potential to become a major tool in inaccessible sub-polar and polar rivers, just as detection of floods has become one of the established applications of remote sensing.…”

“…The model has been widely applied across the globe to successfully characterize the states of aquatic habitats and enhancement projects (Clark et al 2008;De Jalon and Gortazar 2007;Hayes et al 2007;Lacey and Millar 2004;Morse and Hicks 2005). Specific spatial hydraulic metrics have also been integrated with River2D to simulate reach habitat parameters such as velocity and kinetic energy gradients Diplas 2002, 2006).…”

Assessing the effect of Separation Levee Project on Chinese sturgeon (Acipensor sinensis) spawning habitat suitability in Yangtze River, China

Chinese sturgeon (Acipenser sinensis) is a protected anadromous fish species. The migration pattern of the fish has been blocked by the construction of Gezhouba Dam, reducing the natural spawning site length to less than 7 km along the Yangtze River. However, the fish has since established an alternative spawning ground in the narrow reach downstream of Gezhouba Dam. To enhance navigation, a Separation Levee Project (SLP) was implemented in the new-found spawning habitat of the fish. To therefore evaluate the effect of the SLP on Chinese sturgeon spawning habitat suitability, the conditions in the spawning habitat were simulated using River2D (a two-dimensional hydrodynamic model). Two main approaches (habitat kinetic energy and circulation metrics) were used in the simulation. The study showed that SLP only slightly changed the physical conditions in the spawning habitat. Using hydrodynamic simulation, the weighted usable area (WUA) before and after the SLP construction was also computed and habitat preference curve developed for water depth and velocity. On the average, SLP reduced WUA-a finding that was consistent with field-measured data. Based on WUA, the habitat conditions were more sensitive to SLP proximity than metrics based on velocity gradients. SLP posed detrimental impacts on the suitability of spawning habitats of Chinese sturgeon. The findings in this study provide further basis for the protection and restoration of Chinese sturgeon spawning habitats in especially the lower reach of Yangtze River.
