Making an ADCP measurement on the Bear River below Alexander Reservoir, Idaho
Date Published: February 9, 2017

Surface-water information is needed for purposes of surveillance, planning, design, hazard warning, operation, and management, in water-related fields such as water supply, hydroelectric power, flood control, irrigation, bridge and culvert design, wildlife management, pollution abatement, flood-plain management, and water resources development.

Oběh vody: The Water Cycle

Co to je oběh vody?

Co to je oběh vody? Mohl bych si jednoduše odpovědět – je všude kolem mne ! Oběh vody znamená přítomnost a pohyb vody na Zemi, v Zemi i nad Zemí. Voda je stále v pohybu a neustále mění svoji formu, z kapalné do plynné či pevné, a naopak. Oběh vody existuje již po miliardy let a veškerý pozemský život je na něm závislý; Země by bez...

Big Wood River at Hailey, Idaho
Date Published: January 2, 2017

Sampling sediment during high streamflow conditions on the Selway River, Idaho
Date Published: January 1, 2017
Status: Completed

Are there ways to manage sediment before it accumulates in Lower Granite Reservoir? If so, resource managers must know exactly how much sediment is being transported in the lower Snake and Clearwater River basins, the grain-size distribution of the sediment that is being transported, which subbasins are contributing the most sediment, and how the sediment is being deposited once it is...

Erosion along the Rio Puerco during the flood of 2006 following herbicide application to control saltcedar in 2003.
Date Published: December 3, 2016

Formation of arroyos in the late 1800s greatly increased erosion across the southwestern United States. Since the 1930s, however, this erosion has decreased, partly because of bank stabilization by introduced saltcedar. With Isleta Pueblo Indian Nation, the Aquatic Systems Branch developed a new sediment dating method using saltcedar tree rings. We applied the method in a landmark study of...

On the probability distribution of daily streamflow in the United States

Daily streamflows are often represented by flow duration curves (FDCs), which illustrate the frequency with which flows are equaled or exceeded. FDCs have had broad applications across both operational and research hydrology for decades; however, modeling FDCs has proven elusive. Daily streamflow is a complex time series with flow values ranging...
