Clear Creek Gravel Augmentations, 1996-2021
Clear Creek Anadromous Fish Habitat Restoration and Management Project (aka “Gravel Augmentations”), 1996-2021 The purpose of the Clear Creek Gravel Augmentation Project (the Project) is to improve habitat conditions in Lower Clear Creek for anadromous salmonid species, including spring-run, fall-run, and late fall-run Chinook salmon, and Central Valley steelhead. This programmatic effort was formally titled Lower Clear Creek Anadromous Fish Habitat Restoration and Management Project (LCCAFHRMP), though “gravel augmentations” remains the most commonly use name for the project. The Project is implemented annually to improve fish habitat by placing gravel and other desirable materials into the stream channel with the intent of restoring and maintaining the balance of sediment in Clear Creek, providing desirable creek channel attributes like floodplain connectivity, channel migration, fish habitat formation (e.g. spawning habitat), and supporting riparian community development. The Project is proposed to meet the requirements of the CVPIA 3406 (b)(12) which has identified the lack of in-stream spawning gravel as a significant factor limiting anadromous fish reproduction in Clear Creek. The Clear Creek Gravel Augmentation Project consists of adding clean (washed), size-sorted natural river gravel directly (riffle supplementation) or indirectly (talus cone, lateral berm) into the Clear Creek channel, along with other desirable materials (i.e., large wood and boulders). The project is funded by the CVPIA. Each year, the Clear Creek Technical Team chooses the top priority gravel augmentation sites for implementations.
Top view of DR1/DR2 double riffle, each section contains a spawning ground made up of eight gravel-filled trays, a rest area. The "double riffle" was designed to accommodate two groups from 25 to 50 specimens of broodstock in strictly identical conditions. The spawning grounds are equipped with waterproof, motion-sensing cameras with infrared night vision, connected to a 1000 Gb recorder. The diurnal and nocturnal activities of the two groups can therefore be simultaneously recorded over a long period. in Reproduction of Zingel asper (Linnaeus, 1758) in controlled conditions: an assessment of the experiences realized since 2005 at the Besançon Natural History Museum

Data and code for: Grain size of fluvial gravel bars from close-range UAV imagery – uncertainty in segmentation-based data
<p>UAV images used for SfM model generation and all images (both SI and OM), in which we measured grain sizes. The code used for image processing and uncertainty estimation of grain size distributions as python files and executable jupyter notebooks, where the latter also serve as documentation.</p>
Sand and gravel sediment flux data, San Antonio River, Texas
<p>Dataset consists of field observations of sand and gravel sediment fluxes and bed material in the lower San Antonio River, Texas. A Helley-Smith bedload sampler was deployed at three locations over stream discharges that span two orders of magnitude. Details are given in Haschenburger (2021), Fractional Transport Rates in a Poorly Sorted Sand-bed River, Geomorphology, 389, 107797, https://doi.org/10.1016/j.geomorph.2021.107797</p>
River gravel mobility observations, San Antonio River, Texas
<p>This data set characterizes the frequency of gravel mobility in the lower San Antonio River near Floresville, Kenedy, and Goliad, Texas. Mobility data consist of the first flow discharge when a given gravel size was mobile, the general bedload transport conditions during these mobilizing flows, the frequency of mobilizing flow during in a typical year based on flow duration analysis, and the grain size distribution of bed material.
