“…HLR 14 is described by Wolock et al (2004) as "arid playas," which are dynamic landforms. The locations of the sites within HLR 14, which predominately encompasses portions of California, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming, may exhibit greater levels of variability due to changes in snow pack conditions, vegetation, precipitation patterns, and bedload transport (Neal and Motts, 1967;Patten, 1998;Adams and Sada, 2014).…”

Regional curves relate drainage area to the bankfull channel characteristics discharge, cross‐sectional area, width, and mean depth. These curves are used for a variety of purposes, including aiding in the field identification of bankfull elevation and in the natural channel design process. When developing regional curves, the degree to which landform, geology, climate, and vegetation influence stream systems within a single physiographic province may not be fully considered. This study examined the use of the U.S. Geological Survey's Hydrologic Landscape Regions (HLR), as well as data from 2,856 independent sites throughout the contiguous United States (U.S.), to develop a set of regional curves (bankfull discharge, cross‐sectional area, width, and mean depth) for (1) the contiguous U.S., (2) each of the 20 HLRs, (3) each of the eight physiographic divisions, (4) 22 of the 25 physiographic provinces, and (5) individual HLRs within the physiographic provinces. These regional curves were then compared to each other, as well as those from the literature. Regional curves developed for individual HLRs, physiographic divisions, and physiographic provinces tended to outperform the contiguous U.S. indicating increased stratification was beneficial. Further stratifying physiographic provinces by HLR markedly improved regional curve reliability. Use of HLR as a basis of regional curve development, rather than physiographic region alone, may allow for the development of more robust regional curves.

“…In contrast to other units, LU1 appears more sorted with overlapping of edges ("imbricated"), and sand-size grains that are marginally rounded. The appearance of this unit is likely the effects of a repeated influx of water followed by episodic evaporation resulting in rough-crusted surfaces similar to those described by Adams and Sada (2014) and Tollerud and Fantle (2014). LU1 is dissimilar to units LU2, LU3 and ALØ; sediment matrix is very thin laminated silt loam, indicative of a lacustrine water facies overlain a deeper unit (LU0).…”

Shallow Subsurface Evidence for Postglacial Holocene Lakes at Ivanpah Dry Lake: An Alternative Energy Development Site in the Central Mojave Desert, California, USA

Dry lakes, or playas, in the American Southwest have become important locations for alternative energy solar electric generation systems. Many of these playas have not been investigated for past environmental conditions prior to their development, causing alterations to the shallow sediment profile and altering subsurface chemical and physical data important to recent geologic and hydrologic histories of these areas. Recent studies of these features commonly have focused on surficial data with little or no subsurface geologic data to delineate wet and dry cycles of playa lakes. Many of the playa margins are covered with a surficial layer of alluvial and/or aeolian sands varying in thickness, which could interfere with correct interpretations of data gathered only on the surface material on these lands. Over the past 13,000 years Ivanpah Dry Lake has had at least three episodes of lake highstands up to ~10m in response to climate changes, based on data in this study with the oldest episode dates to ~13,000 cal yrs BP. This study has a link to other sites as many other playas are slated for energy development and could endure subsurface data alteration during site reworking and occupation, resulting in a loss in their collective historical geologic and hydrologic records if more complete studies of important sites are not carried out before developments begin.

“…Reynolds et al (2007) defined playas with sallow groundwater as wet playas where the shallow depth of groundwater allows its evaporation, leaving behind very soft surfaces. Studies have shown that hard clay and silt-rich playas can transform to puffy and soft playas due to capillary movement of shallow groundwater (Adams and Sada, 2014). The Lake Urmia surface area and depth vary seasonally.…”

Lake Urmia is one of the most important salt lakes in the world and the largest in Iran. At present, because of the recession of Lake Urmia and deposition of lacustrine sediments on the lake bed, a large part of the surrounding areas has become flat with several playa surfaces. So far, there have been very few studies related to Lake Urmia playa and its geomorphology. Therefore, the aim of this research was to field study of playa surfaces of Lake Urmia in its eastern part and also to identify areas susceptible to wind erosion. In this study, different playa surfaces from the northeast to the south of the lake were identified and mapped using satellite imagery. Then, boundaries of the mapped surfaces were checked during field observations. Moreover, physical soil properties, such as texture, bulk density, saturation percentage, resistancy, particle size distribution and soil aggregate stability, were determined. Next, the correlation of the studied properties with each surface resistance to wind erosion was investigated, and finally the geomorphic surfaces of Urmia Playa and their resistance to wind erosion were mapped using ARCGIS software. Based on the results, the study area included agricultural lands, shrub-grass zones, sand and gravel zones, mud-clay salt flats, sand-salt crusts, puffy grounds, delta-fans and wet zones. Results showed that approximately 25% of the surfaces had high resistance to wind erosion and they are therefore stable surfaces with no potential for generating dust in the future. About 35% of the surfaces were strongly susceptible to wind erosion, highly prone to generate saline dusts and sand storms. These areas were located in the east and southeast of the lake. Also, 40% of playa surfaces had moderate resistance to wind erosion. These areas can become very sensitive to wind erosion if ground water depth or the roughness of the surface changes. In conclusion, sandy-salt surfaces in the east and southeast of the lake are the most susceptible to wind erosion with high potential for generating dust, sand, and salt storms, which can affect agricultural lands and human health in the near future.
