Estimates of Evapotranspiration and Evaporation along the Lower Colorado River

Submitted by atripp on Tue, 03/31/2020 - 11:07

The Colorado River is the principal source of water for agriculture and riparian vegetation in Arizona, southern California, and southern Nevada. The BOR Lower Colorado Region accounts for water use in each state, verifies water conservation programs, and fulfills other water management information needs in the Lower Colorado Basin.

Population at Risk Studies for Dam Failure Loss of Life Analysis

Submitted by atripp on Fri, 11/30/2018 - 14:47

BOR Population at Risk studies are used to determine the possible magnitude of loss of life in the event of a dam failure. Inundation extent, population at risk, and life loss estimation are the three components commonly considered in failure consequences. Remotely sensed data play a major role in determining population locations and densities.

Great Smoky Mountains National Park Vegetation Mapping Project

The USGS Upper Midwest Environmental Sciences Center (UMESC) is producing a seamless vegetation map of Great Smoky Mountains (GRSM) National Park.  The UMESC has been conducting vegetation mapping for the National Park Service (NPS) for over a decade.  These highly accurate and highly detailed vegetation maps are used by individual parks to manage lands and conduct research.  High-resolution (0.305-m or better) 4-band digital imagery was collected during peak fall color.  For GRSM, this meant three separate flights for the entire park to capture the progression of fall color from the highes

Biologic Carbon Sequestration Assessment

Submitted by Anonymous (not verified) on Mon, 07/30/2018 - 14:12

This is an interdisciplinary effort to assess ecosystem carbon sequestration capacity for all domestic ecosystems as a function of climate, land use, land management and disturbances. The integrated assessment relies on existing data collected by various national inventory, monitoring, and remote sensing programs. The USGS is conducting research in collaboration with multiple partners to improve understanding of carbon cycling processes, assessment methodology capabilities, and uncertainties related to data, model, and existing knowledge.

Monitoring Change in the Bureau of Land Management (BLM) National Monuments

Submitted by Anonymous (not verified) on Mon, 07/30/2018 - 14:12

A remote sensing project in cooperation with Northern Arizona University and the BLM detects newly created networks from illegal human activities: vehicular routes, human trails, and accumulations of litter, debris, and hazardous materials. The project will assist in evaluating the health of the landscape and public enjoyment of national monuments.
