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."

Mazourek, A.C. McColpin, R.B. Renken, and R.D. Semlitsch.  (1988).  "Flooding to Restore Connectivity of Regulated, Large-River Wetlands:  Natural and Controlled Flooding as Complementary Processes Along the Lower Missouri River."  "Managed, or controlled, flooding is actively practiced along the lower Missouri River.  Controlled flooding is, however, restricted to small parcels of intensively managed public lands and largely benefits migrant waterbirds.  In this article, the authors provide a historical perspective on the development of controlled flooding and intensive wetland management as natural flooding disappeared along the lower Missouri River."

Holly Jr., F.M., and M.F. Karim.  (1986).  "Simulation of Missouri River Bed Degradation."  The authors speak about their predictions of the future course of bed degradation in the middle Missouri River.  Their findings, through the use of numerical simulation techniques, show that the "worst of the degradation is now over, and that it is the channelization, rather than upstream regulation, which is primarily responsible for the degradation."

 

Hotchkiss, R. H., S.F. Jorgensen, M.C. Stone, and T.A. Fontaine.  (2000). “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."

 

Johnson, H., R. Jacobson, and A. Delonay. (2006). “Hydroecological Modeling of the Lower Missouri River."  "The Lower Missouri River (LMOR) has been altered in both its channel form and flow regime by channelization and upstream dams.  As a result, habitat availability for many fish species has been greatly modified or lost…  To evaluate habitat availability on the LMOR, we developed a 2-dimensional, depth-averaged hydrodynamic model of a representative 8-km reach near Boonville, Missouri.  The model provides an inventory of hydraulic habitat over discharges ranging 1-99% flow exceedance….”

 

Johnson, W.C., P.W. Reiley, L.S. Andrews, J.F. McLellan, and J.A. Brophy.  (1982).  "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 of geomorphologic changes."
