Bovee, K.D.,
and M.L. Scott. (2002). "Effects
of Flow Regulation on the Upper Missouri River, USA: Implications
for Flood Pulse Restoration." "The authors
developed a mass balance flow model to reconstruct unregulated daily peak
flows in the National Wild and Scenic reach of the Missouri River, Montana.
Results indicated that although the observed frequency
of large peak flows has not changed in the post-dam period, their magnitude
has been reduced from 40 to 50% as a consequence of flow regulation. Reductions
in the magnitude of these flows should reduce the expected frequency of
large flood-pulses over a longer time-scale. Results
of a two-dimensional hydraulic model indicated that limited cottonwood
(Populus deltoides subsp.
Monilifera)
recruitment occurs at relatively small peak discharges, but to maximize
establishment of cottonwoods in the Wild and Scenic reach, a threshold
of 1,850 m3/s would be necessary
at the Virgelle gauge. Floods
of this magnitude or greater lead to establishment of cottonwood seedlings
above the zone of frequent ice-drive disturbance. Restoring
the frequency, magnitude, duration, and timing of these flood pulses would
benefit important natural resource values including riparian cottonwood
forests and native fish species in the upper Missouri River basin. However,
efforts to naturalize flow must be made in the context of a water management
system that was authorized and constructed for the primary purposes of
flood control, power generation and irrigation. Using
the synthesized flow model and flood damage curves, the authors examined
six scenarios for delivering flows >
1,850 m3/s to the Wild and
Scenic reach. Whereas some scenarios appeared to
be politically and economically infeasible, the authors' analysis suggested
that there is enough operational flexibility in the system to restore
more natural flood pulses without greatly compromising other values."

is actively practiced along the lower Missouri River. Controlled

“Regulated River Modeling for Climate Change Impact Assessment: The
Missouri River." "The Great Plains of
the United States, drained primarily by the Missouri River, are very sensitive
to shifts in climate. The six main stem dams on
the Missouri River control more than one-half of the nearly 1.5 million
square kilometer basin and can store three times the annual inflow from
upstream. The dams are operated by the U.S. Army Corps of Engineers using
a Master Manual that describes system priorities and benefits. The complex
operational rules were incorporated into the Soil and Water Assessment
Tool computer model (SWAT). SWAT is a distributed parameter rainfall-runoff
model capable of simulating the transpiration suppression effects of CO2
enrichment. The new reservoir algorithms were calibrated using a 25-year
long historic record of basin climate and discharge records. Results demonstrate
that it is possible to incorporate the operation of a highly regulated
river system into a complex rainfall-runoff model. The algorithms were
then tested using extreme climate scenarios indicative of a prolonged
drought, a short drought, and a ten percent increase in basin-wide precipitation.
It is apparent that the rules for operating the
reservoirs will likely require modification if, for example, upper-basin
precipitation were to increase only ten percent under changed climate
conditions."

"Altered Hydrology of the Missouri River and
Its Effects on Floodplain Forest Ecosystems." "It
is generally expected that construction and operation of a floodplain
protection project will alter a river system's hydrologic regimen. But
this altered regimen also has been suspected of having major, long-term
effects on the natural dynamics of riparian ecosystems that remain in
gaps between large reservoirs. This study confirms
that hypothesis by documenting some of those impacts in an area between
Garrison Dam and Oahe Reservoir on the Missouri River in south-central
North Dakota. Specifically, it examines post-dam
changes in river meandering rate, floodplain forest composition, tree
population structure, and tree growth rate...Results of this study should
have application to forests on other floodplains where the natural hydrologic
regimen has been altered by man. This research
should stimulate further study of riparian ecosystems so that a more general
assessment can be made of the ecological effects of floodplain protection."

Perry,
C.A. (1993). "Effects
of Reservoirs on Flood Discharges: Floods in the
Upper Mississippi River Basin." "During
spring and summer 1993, record flooding inundated much of the upper Mississippi
River basin. The magnitude of the damages--in terms
of property, disrupted business, and personal trauma--was unmatched by
any other flood disaster in United States history. Property
damage alone is expected to exceed $10 billion. Damaged
highways and submerged roads disrupted overland transportation throughout
the flooded region. The Mississippi and the Missouri
Rivers were closed to navigation before, during, and after the flooding.
Millions of acres of productive farmland remained
under water for weeks during the growing season. Rills
and gullies in many tilled fields are the result of the severe erosion
that occurred throughout the Midwestern United States farmbelt. The
hydrologic effects of extended rainfall throughout the upper Midwestern
United States were severe and widespread. The banks
and channels of many rivers were severely eroded, and sediment was deposited
over large areas of the basin's flood plain. Record
flows submerged many areas that had not been affected by previous floods.
Industrial and agricultural areas were inundated,
which caused concern about the transport and fate of industrial chemicals,
sewage effluent, and agricultural chemicals in the floodwaters. The
extent and duration of the flooding caused numerous levees to fail. One
failed levee on the Raccoon River in Des Moines, Iowa, led to flooding
of the city's water treatment plant. As a result,
the city was without drinking water for 19 days.
As the Nation's principal water-science agency,
the U.S. Geological Survey (USGS) is in a unique position to provide an
immediate assessment of some of the hydrological effects of the 1993 flood.
The USGS maintains a hydrologic data network and
conducts extensive water-resources investigations nation wide. Long-term
data from this network and information on local and regional hydrology
provide the basis for identifying and documenting the effects of the flooding.
During the flood, the USGS provided continuous
streamflow and related information to the National Weather Service (NWS),
the U.S. Army Corps of Engineers, the Federal Emergency Management Agency
(FEMA), and many State and local agencies as part of its role to provide
basic information on the Nation's surface- and groundwater resources at
thousands of locations across the United States. The
NWS has used the data in forecasting floods and issuing flood warnings.
The data have been used by the Corps of Engineers
to operate water diversions, dams, locks, and levees. The
FEMA and many State and local emergency management agencies have used
USGS hydrologic data and NWS forecasts as part of the basis of their local
flood-response activities. In addition, USGS hydrologists
are conducting a series of investigations to document the effects of the
flooding and to improve understanding of the related processes. The
major initial findings from these studies will be reported in this Circular
series as results become available.
U.S. Geological Survey Circular 1120, Floods
in the Upper Mississippi River Basin, 1993, consists of individually published
chapters that will document the effects of the 1993 flooding. The
series includes data and findings on the magnitude and frequency of peak
discharges; precipitation; water-quality characteristics, including nutrients
and man-made contaminants; transport of sediment; assessment of sediment
deposited on flood plains; effects of inundation on groundwater quality;
flood-discharge volume; effects of reservoir storage on flood peaks; stream-channel
scour at selected bridges; extent of floodplain inundation; and documentation
