Special Issue Information

Dear Colleagues,

Water and wetland ecosystems provide valuable water resources for human society while supporting a wide range of plant and animal species. Driven by climatic and anthropogenic factors, open surface water and wetlands across the world are experiencing rapid changes.

Global warming and climate change have dried out numerous lakes and ponds worldwide. Meanwhile, the increasing temperature is thawing the permafrost in Arctic wetlands, changing their water regimes and vegetation types. The increasing demands of public water supply, irrigation, and hydroelectric power have led to the construction of new reservoirs, while the land reclamation for housing and agriculture has led to the loss of natural water bodies and wetlands.

The availability of fine resolution remote sensing data (e.g., Landsat, Sentinel, PALSAR, RADARSAT) and the development of new algorithms (e.g., machine learning, deep learning) have advanced the techniques in water and wetland mapping and their change analysis.

This Special Issue of Water aims to collect research related to different aspects of mapping and change analysis of water and wetland. The potential research topics include but are not limited to:

  • Exploring different remote sensing data (e.g., optical, SAR, LiDAR, UAV, etc.) in the mapping of water or wetland;
  • Exploring different approaches (e.g., field survey, indexing, machine learning, deep learning, etc.) in the mapping of water or wetland;
  • Analyzing changes of water or wetland across different time periods (e.g., seasonal, annual, decadal, etc.);
  • Analyzing natural or anthropogenic drivers (e.g., climate change, drought, flood, reservoir construction, land reclamation, etc.) of water or wetland changes;
  • Using big data, high-performance computers, and cloud-computing platforms (e.g., Google Earth Engine) in water or wetland mapping and change analysis.

Lakes are sensitive indicators of climatic change and are important resources for regional economic development. In recent years, there have been many studies related to the changes in lake area and lake volume. However, further studies are still required to understand the responses of lakes to climatic change and human activities. This paper utilizes lakes in the Qaidam Basin, an inland arid region of China, as the object of study and investigates the characteristics of variability in lake changes and its driving forces by combining multi-source remote sensing, model simulations and historical data. We first analyzed the spatiotemporal pattern of climatic change in the basin under the background of global warming. The response of lake water volume to climatic change and human activities is then discussed. Finally, the main factors that affect the change in lake water volume in different regions of the basin are delineated. The water volume of lakes in the Qaidam Basin increased by 3.81 km3 from 1990 to 2020. Particularly since the 21st century, the water volume of lakes has increased rapidly, and an increasingly abrupt change appeared around 2015. The increases in precipitation and vegetation area are the main and secondary factors that led to the increase in total lake water volume in the basin, respectively. However, the main influencing factors still vary in different regions. The impact of air temperature, evaporation, and changes in the cropland area on the change in lake water volume is generally not obvious. Human activities, such as the development of salt lakes and damming, have led to substantial changes in the spatial pattern of lakes in the middle of the basin and are associated with the replacement, genesis, and disappearance of Yiliping Lake, Yahu Lake and West Taijinar Lake, respectively. This study reveals the changing characteristics of climate and lake water volume in inland arid basins in China, which are highly important to understand the responses of lakes to climatic change and human activities, and provides a scientific basis for the rational development and utilization of lake resources in arid basins.

Stream permanence classifications (i.e., perennial, intermittent, ephemeral) are a primary consideration to determine stream regulatory status in the United States (U.S.) and are an important indicator of environmental conditions and biodiversity. However, at present, no models or products adequately describe surface water presence for regulatory determinations. We modified the Thornthwaite monthly water balance model (MWBM) with a flow threshold parameter to estimate flow permanence and evaluated the model’s accuracy and precision for more than 1.3 million headwater stream reaches in the U.S. Pacific Northwest (PNW). Stream reaches were assigned to one of eight calibration groups by unsupervised classification based on sensitivity to MWBM parameters. Suitable MWBM parameter sets were identified by comparing modeled stream permanence estimates to surface water presence observations (SWPO). Parameter sets with accuracies > 65% were considered suitable. The MWBM estimated stream permanence with high precision at 40% of reaches, with poor precision at 20% of reaches, and no suitable parameter sets were identified for 40% of reaches. Results highlight the need for increased SWPO collection to improve calibration and assessment of stream permanence models. Additionally, implementation of the MWBM to estimate surface water presence indicates potential for process-based models to predict stream permanence with future development. Full article
