Using Fine Sediment Monitoring to Quantify Sand Loading Over Time

River Research and Applications, EarlyView.
ABSTRACT Riverine sand loading can lead to geomorphic change, impacting river processes like lateral migration and vertical aggradation or degradation. Yet many sediment monitoring programs track only fine sediment measurable as total suspended solids (TSS). Here, we assess the ability for TSS data to be used to determine sand loading.

Spatiotemporal Assessment of Groundwater Interactions With a Regulated River: A Case Study of the Nechako River, Canada

River Research and Applications, EarlyView.
ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.

Geomorphic Effects and Habitat Impacts of Large Wood at Restoration Sites in New England

River Research and Applications, EarlyView.
ABSTRACT Large wood (used interchangeably with the term “instream wood”), which refers to trees, logs and other wood within a channel, is beneficial to river ecosystems and is being used more frequently as a component of river restoration projects. We identified metrics to evaluate the effectiveness of large wood to promote ecological and geomorphic ...

Population Dynamics of Northern Pearl Dace Margariscus nachtriebi in Anthropogenically Altered Headwater Streams of the Nebraska Sandhills Ecoregion

River Research and Applications, EarlyView.
ABSTRACT Empirical evidence of population demographic responses to environmental perturbations is a major knowledge gap for aquatic vertebrate populations. Extensive habitat alteration including channelization of headwater streams influences the habitat template on which small‐bodied fish are dependent to carry out distinct life stages and maintain or ...

Field-programmable gate arrays (FPGAs) are a promising technology that can be used in database systems. In this demonstration we show Glacier, a library and a compiler that can be employed to implement streaming queries as hardware circuits on FPGAs.

This chapter explores the glaciers of the Sierra Nevada. Like all mountain glaciers, those of the Sierra began high up in the range where massing snow persisted in shadowed mountain cradles through summer. Though glaciers have expanded across and retreated from the range numerous times during the past two-and-a-half million years, the glaciers now in ...

Though not traditionally thought of as strategic natural resources, glaciers are a crucial part of our global ecosystem playing a fundamental role in the sustaining of life around the world. Comprising three quarters of the world's freshwater, they freeze in the winter and melt in the summer, supplying a steady flow of water for agriculture, livestock,
