Special Issue Information

Dear Colleagues,

Remote sensing has been proliferating in recent years. A series of recently launched satellites provide new data for understanding the water cycle and freshwater resources. Commercial satellites with hyper spatial and temporal resolutions are in orbit. Airborne remote sensing has been increasingly used for monitoring surface water systems. The improved remote sensing techniques and exponentially increased remote sensing data, accompanied with advanced analytical tools, provide unprecedented opportunities for monitoring surface water systems and informing water resources management at various spatial and temporal scales.

The aim of this Special Issue is to cover studies that use remote sensing to address scientific and operational challenges in river/lake science from local to global scales. Topics may include improving the ability of remote sensing to quantify surface water variables using new satellite and airborne remote sensing technologies (e.g., Sentinel-2, Sentinel-3, ICESat-2, SWOT, PlanetScope, and UAVSAR), advanced approaches (e.g., data fusion, machine learning, and data assimilation), or efficient analytical tools dealing with big remote sensing data. Studies that focus on pressing challenges of surface water resources, such as monitoring water quality, tracking flow and storage changes in small water bodies, and quantifying human alterations of surface water systems, are also encouraged.

Articles may address, but are not limited to, the following topics:

  • Flow rate and velocity;
  • Water storage;
  • Water quality;
  • Small rivers/lakes;
  • Geomorphological status and evolution;
  • Human regulations;
  • Multi-sensor data fusion;
  • Integration of remote sensing and modeling;
  • Data assimilation;
  • Machine learning and artificial intelligence.

The concentration of colored dissolved organic matter (CDOM) in lakes is strongly influenced by climate, land cover, and topographic settings, but it is not known how drought may affect the relative importance of these controls. Here, we evaluate the controls of CDOM during two summers with strongly contrasting values of the Palmer drought index (PDI), indicating wet vs. dry conditions. We hypothesized that lake CDOM during a wet summer season is regulated mainly by the surrounding land cover to which the lakes are hydrologically connected, while, during drought, the lakes are disconnected from the catchment and CDOM is regulated by climatic and morphometric factors that govern the internal turnover of CDOM in the lakes. A suite of climate, land cover, and morphometric variables was assembled and used to explain remotely sensed CDOM values for 255 boreal lakes distributed across broad environmental and geographic gradients in Sweden and Norway. We found that PDI explained the variability in CDOM among lakes in a dry year, but not in a wet year, and that severe drought strongly decreased CDOM during the dry year. Large lakes, especially, with a presumed high degree of catchment uncoupling, showed low CDOM during the dry year. However, in disagreement with our hypothesis, climate, land cover, and morphometry all showed a stronger impact on lake CDOM in wet vs. dry years. Thus, drought systematically weakened the predictability of CDOM variations at the same time as CDOM was offset toward lower values. Our results show that drought not only has a direct effect on CDOM, but also acts indirectly by changing the spatial regulation of CDOM in boreal lakes. Full article

Reservoirs are essential hydraulic facilities for water resource allocation in Xinjiang. Since the 1950s, many reservoirs have been constructed for oasis water resource utilization in Xinjiang, enhancing the storage capacity of water resources. There are a few intact and open reservoir archives containing both geolocations and hydraulic attributes, such as the reservoir completion year, which can facilitate our understanding of the correlation between hydraulic engineering and oasis expansion. This paper mapped all the reservoirs of Xinjiang using Sentinel-2 MSI images from 2022. It associated their attributes with the reservoir’s extent, such as the capacity, area, complete year, altitude, etc., by consulting historical almanac data to establish a full elemental dataset with both geographic and attribute information. Furthermore, the spatial variability and historical process of the reservoirs were discussed against geomorphic information and oasis evolution. The results showed that 804 reservoirs were mapped cumulatively in Xinjiang up to 2022, and 1960–1980 and 2005–2010 are the rapidly developed periods. The construction history of the reservoirs indicates that reservoirs’ locations have the spatial tendency to shift from being in oasis plain areas to mountainous areas, and the newly built reservoirs showed a trend of miniaturization in area and maximization in volume.
