Prototype Two-Dimensional Real-Time Beaver Lake Modeling System


Real-time data are collected at a location on Beaver Lake near Lowell, Arkansas by a lake diagnostic station (LDS) The LDS has been in operation since January 30, 2008. Real-time data include air temperature, relative humidity, wind speed and direction, shortwave and net longwave radiation, water temperature at 16 depths in the water column, and dissolved oxygen concentrations at 8 depths in the water column. Data are recorded every 30 seconds and transmitted hourly to the USGS Arkansas Water Science Center website ( http://ar.water.usgs.gov ), station number 07049200.

Provisional Data -- Subject to Review


The real-time data from the LDS is used to run an existing two-dimensional model of hydrodynamics and water quality in Beaver Lake that has been developed and published by the USGS in cooperation with Beaver Water District, Arkansas Department of Environmental Quality, Arkansas Natural Resources Commission, U.S. Environmental Protection Agency, and U.S. Army Corps of Engineers for Beaver Lake ( http://pubs.usgs.gov/sir/2006/5003/SIR2006-5003.pdf , and http://pubs.usgs.gov/sir/2006/5302/pdf/SIR2006-5302.pdf ).
