Recent advances in sensor technology and data telemetry allow a range of
surface meteorological and vertical water-column data to be collected
simultaneously, in real time, for lakes and reservoirs. With recent advancements
in computer technology, three-dimensional lake and reservoir models can be run
in much shorter time frames, allowing for real-time simulations of hydrodynamics
and water quality. Together, these advances allow for the development of quasi-real-
time decision-support systems for water quality management of individual
lakes and reservoir systems. Using real-time instrumentation, the models can
"learn" from the data and continuously check their predictive capabilities. Real-time
model simulations will provide necessary information for "data-driven"
monitoring schemes designed to examine current physical, chemical, and
biological conditions that impair the water quality of a lake or reservoir, like algal
blooms. For example, real-time model simulations and resultant animations of
algal patch development (functional groups like nitrogen-fixing cyanobacteria or
even species like Microcystis aeruginosa), which may be responsible for taste
and odor or toxin problems in drinking water, will provide up-to-date information
that can be used by monitoring teams to cost-effectively target data-collection to
specific locations in the lake or reservoir and collect data throughout the growth
phase and subsequent crash of the algal population. Until recently, recognition of
an algal bloom in a lake or reservoir did not happen until after the bloom peaked
or crashed, and then too late to collect information about the conditions that
propagated the bloom. Understanding the processes that lead to an algal bloom
and water quality impairment will aid in the design of in-lake or landscape
engineering or management solutions to reduce or eliminate future impairments.
Example applications of the recent technology (using idealized conditions)
include two reservoir systems and one lake: Beaver Lake, an impounded
mountain valley reservoir in the Ozarks of northwestern Arkansas; Lake Houston,
an impounded flood-plain reservoir near the Gulf Coast of Texas; and, the south
arm of the Great Salt Lake. Includes abstract only.
