 | Construction of navigation locks and dams on the upper Mississippi River about 60 years ago submerged wing dam training structures, thereby reducing their effectiveness and increasing secondary channel and floodplain conveyance. The U.S. Army Engineer District, St. Paul, executed a drawdown of Pool 8 (upstream of Lock and Dam No. 8) near La Crosse, WI, during the summers of 2001 and 2002. Water levels were allowed to drop below normal ... |

| The U.S. National Security Strategy for Homeland Security identifies the U.S. water infrastructure as one of the nation's critical infrastructures. Experts and several reports to Congress point out the vulnerabilities of domestic water supply and distribution systems to terrorism and the ramifications of a successful attack. Starting in the late 1990s the federal government implemented a host of actions intended to protect domestic water supplies. Despite these efforts critical vulnerabilities ... |

| The Department of Defense (DoD) has hundreds of thousands of facilities in its inventory, which consume billions of BTUSs of energy per year. Much of that energy is used to heat and cool the facility, and a great deal of this energy is lost through the building envelope. While new military construction works towards energy efficiency, the majority of DoD facilities were built over forty years ago with little regard ... |

| Natural runoff processes have been altered by urban development; impervious surfaces (rooftops, highways, parking areas) and their associated storm water systems channel runoff from a vast area into one concentrated outflow. This storm water runoff can cause erosion, flooding, landslides, and significant damage to aquatic ecosystems. Runoff from highways and parking areas has also been known to contain high levels of suspended solids, heavy metals and hydrocarbons. Porous pavements allow ... |

| Prior to development of the Tennessee Tombigbee Waterway (TTW), the Tombigbee River was well-known for supporting a dense and diverse fauna, including sculpins, minnows, mussels, snails, worms, and immature insects. Completion of this project dramatically altered the habitat characteristics of the river, converting free-flowing pool and riffle sequences to a series of reservoirs. Resource agencies expressed some concerns over the loss of shallow riffle habitat, since large numbers of state-listed ... |

| Critical infrastructure consists of systems and assets so vital to the United States that their incapacity would harm the nation's physical security, economic security, or public health. Critical infrastructure is often geographically concentrated, so it may be distinctly vulnerable to events like natural disasters, epidemics, and certain kinds of terrorist attacks. Disruption of concentrated infrastructure could have greatly disproportionate effects, with costs potentially running into billions of dollars and spreading ... |

| Bank recession resulting from surficial erosion and mass failure is a consequence of hydraulic forces and geotechnical processes. One important set of geotechnical processes in regions where seasonal frost forms is soil freeze-thaw (FT) cycling and associated ground-ice growth and melt. In cold regions soil FT processes usually cause more bank recession annually than other processes. The magnitude of FT effects is variable, depending on soil type, water content, and ... |

| The calculation of longshore sediment transport (LST) rates is a key component of most coastal engineering studies. While the LST process is conceptually simple, in practice the development of reliable rates is made difficult by problems associated with collecting accurate field data, by limitations to model predictions, and by substantial variations of the rates in time and space. This Coastal and Hydraulic Engineering Technical Note (CHETN) summarizes the state of ... |
