Numeric Modeling and Advanced Technologies

The NVWSC has a talented team of modellers, hydrologists, and programmers that keep us at the forefront of hydraulic and hydrologic modelling and the use of advanced technologies for hydrology. We also host a large cluster of high-throughput computing equipment for running model simulations.

Quantifying watershed controls on fine sediment particles and nutrient loading to Lake Tahoe using data mining and machine learning

Since the late 1980’s, the USGS has collected discharge, sediment, and water quality data at seven major drainages under the Lake Tahoe Interagency Monitoring Program (LTIMP). Recently, continuous, real-time measurements of turbidity were added to the LTIMP. These data can be combined with in situ, model simulations, and remotely-sensed datasets available from the USGS, National Aeronautics and...

Development of landscape variables to inform models of meadow vulnerabilities and adaptation under changing climate

The USGS Nevada Water Science Center is providing technical assistance for the collection of landscape variables hypothesized to influence meadow responses to climate and restoration activities. These data will be used in a decision support framework developed by the U.S. Forest Service (USFS) and Desert Research Institute (DRI).

Quantifying Seepage Losses on the Truckee Canal, Derby Dam to Lahontan Reservoir

Seepage losses from the Truckee Canal poses major challenges to water managers. Seepage losses result in inefficiencies in water delivery and cause more water than is needed by farmers to be diverted from the Truckee River to meet required demands. Increased diversions from the Truckee River result in less water flowing through the lower Truckee River system and into Pyramid Lake, a terminal lake...

TROD: Temperature Profiling Probe

Temperature measurements are routinely made for investigating ecological and hydrological processes. Temperature is a key parameter for monitoring the suitability of fisheries habitat and streambed temperature data are useful for estimating surface water and groundwater exchange. Measuring vertically nested temperatures at the streambed interface poses practical challenges.

Lake Tahoe Nearshore Periphyton Study

Periphyton, a type of algae, is growing on bottom sediment and rocks along nearshore areas of Lake Tahoe. Periphyton is seen as a nuisance and negatively impacts the recreational value of the lake. Periphyton biomass (PB) data collected along the nearshore of Lake Tahoe exhibit increasing trends over the last decade. However, the mechanisms that have caused these changes are not well understood.

Hydrology of the Walker River Basin

Walker Lake is one of the few perennial, natural terminal lakes in the Great Basin. The ecosystems and recreational uses of Walker Lake and other terminal lakes in the Great Basin have become at-risk due to consumptive water use.

Aquifer Tests in Nevada

Many aquifer tests have been conducted by the U.S. Geological Survey to estimate hydraulic properties of aquifers in Nevada and adjacent states. Transmissivity is the principal hydraulic property that has been estimated from the aquifer tests in Nevada because these values directly affect estimates of ground-water flow.

Evaluation of Streamflow Depletion Related to Groundwater Withdrawal, Humboldt River Basin

The Humboldt River Basin (HRB) is the only major river basin that is entirely within the State of Nevada. Precipitation supplies all the water that enters the basin; consequently, the variability in climate has significant impacts on the hydrology of the area.

Science in the Colorado River Basin

The Colorado River is one of the longest rivers in the Western United States. It begins in the Rocky Mountains of Colorado and flows southwestward until it reaches Mexico where it becomes a small stream or dry riverbed. The Colorado River forms the border between southeastern Nevada and northwestern Arizona. In Nevada, Hoover Dam and Davis Dam control the flow of the river and create two...

Water Resources of the Upper Humboldt River Basin

Elko County officials and citizens are concerned about growing demand for groundwater within the county and demands for groundwater that are occurring elsewhere in the state. Because the Humboldt River is fully appropriated, any additional water needed to support growth in the upper Humboldt River Basin will have to come from groundwater. County and state water-resource managers need information...

Science in the Humboldt River Basin

The Humboldt River is in north-central Nevada. The river is about 330 miles long and provides water for mostly agricultural purposes. One of the largest industries in Nevada is gold mining and the majority of those mines are in the Humboldt River Basin on the Carlin Trend. Gold mines in Nevada produce close to 80 percent of all the gold in the U.S. and are the 4th largest in the world. In 2010...
