Although further improvement is warranted, the algorithm provides an effective means of obtaining detailed information about ephemeral streams, which could make a significant contribution toward improving the hydrological modeling of desert environments. Although the algorithm captured detailed stream channels, it often underestimated channels obscured by bright soils and sparse vegetation. The accuracy in mapping channel areas and centerlines was as high as 92% and 91%, respectively. Step bedforms include a lot of incredibly diverse channel structures, which are widespread in different regions of the globe, including humid areas, desert ephemeral streams, semiarid environments. The Ten Tributaries all originate from the Erdos Plateau and cross the Kubuqi Desert in their middle reaches (Fig. The algorithm extracted ephemeral stream lengths approximately 900% greater than those identified in the National Hydrography Dataset. The Maobula Gully is an ephemeral desert stream of the Ten Tributaries, which are first-grade tributaries of the Yellow River between the two hydrological stations of Sanhuhekou and Toudaoguai. Knowledge about landscape features such as shrubs and desert pavement and their spatial arrangement was integrated into the algorithm using spectral transformation and spatial statistical operations. Using veryhigh-spatial-resolution imagery, we developed a new algorithm to map desert ephemeral streams in the southwestern U.S., where utility-scale solar energy development is altering the landscape. Ecological Site Concept: This ephemeral stream ecological site occurs on first order channels and stream terraces on upper alluvial fans.

An ephemeral river is a river that only flows when there is rain or snow has. Approximately one-quarter of the land on Earth is threatened by desertification. Desert The Great Indian Desert lies to the northwest of the Aravali hills. Although remote sensing is effective for obtaining information on large areas, conventional techniques are often ineffective or cost-prohibitive for complex stream networks in expansive desert regions. In the 1970s, the Sahel strip that stretches along the southern fringe of the Sahara Desert in Africa experienced a devastating drought, causing land that was formerly used for grazing to turn to desert in a process known as desertification. Watershed-scale typically underestimate total channel length and the size of channel networks. Mapping of ephemeral streams in desert environments is crucial to understanding the impacts to hydrologic and ecosystem functions caused by land-use changes.
