 | Regional Sediment Management (RSM) refers to the effective use of littoral, estuarine, and riverine sediment resources in an environ-mentally effective and economical manner. The U.S. Army Corps of Engineers manages lands and waterways across the United States. The Corps' use of RSM concepts will significantly improve the its mission accomplishment. As part of that mission, Corps engineers and scientists develop new technologies to make management decisions more accurate and efficient. ... |

| During the past several hundred years, many dams have been built in the United States to meet the power, water supply, flood control, and recreational needs of a variety of users. The National Research Council estimates that there are about 2.5 million dams in the United States, ranging from small farm pond dams to large hydropower dams (NRC 1992). Recently, increased awareness of the ecological, recreational, economic, and safety issues ... |

|
| Hydraulic modeling of ice jams can be used to predict jam location, stages, thickness, and other characteristics. Knowledge of the range and variability of hydraulics and physical properties affecting ice jams is necessary to reduce the uncertainty associated with such modeling. This report provides an overview of the processes involved in ice jam hydraulics and discusses properties important in these processes. |

|
| This report provides information on the CRREL Ice Jam Database and its potential use for analyzing ice-related flooding problems. Rivers in the northern United States are subject to ice jams that cause flooding; block hydropower and water supply intakes; delay or stop navigation; damage riverine structures such as locks, dams, bridges, dikes, levees, and wingwalls; and decrease downstream discharge. The lack of readily available information on historical ice events hinders ... |

|
| An ice jam is an accumulation of ice in a river that restricts water flow and may cause backwater that floods low-lying areas upstream from the jam. Downstream areas also can be flooded if the jam releases suddenly, sending excessive water and ice downstream. Damages resulting from ice jam can affect roads, bridges, buildings, and homes, and can cost the affected community thousands to millions of dollars. More common, however, ... |

| Ice processes are capable of causing damage to Corps of Engineers flood control, water control, and navigation projects each year. Monitoring of ice and other physical parameters is done by instrumentation in some instances but is usually done manually. Measurements that require personnel to go on an ice cover can be risky or impossible, depending on the ice cover's stability and the individual's training. This study seeks to identify and ... |

|
| This report presents the results of the Corps of Engineers' Section 22 study of ice jam flooding in the Lower Platte River basin. The purpose of the study was to gather and analyze historical data relating to ice jams, with the intent of developing guidance that can be used to alleviate ice jam flooding at seven sites within the study area. Ice event and related information is summarized for each ... |

| In recent years, drought conditions in the Missouri River basin have required more accurate control of releases at Gavins Point Dam, the further most downstream flow control structure on the river, to meet competing water needs for irrigation and recreation upstream and for navigation and municipal and industrial water supply downstream. In winter, ice accumulations can seriously affect flow distribution along the river. This paper summarizes a study of such ... |

| This report responds to your request that we review the Department of Education's Women's Educational Equity Act (WEEA) Program. First authorized by Public Law 93-380, the Education Amendments of 1974, this program awards grants and contracts to eligible recipients for interventions to (1) provide educational equity for women, (2) help educational institutions meet the requirements of title IX of the Education Amendments of 1972 prohibiting sex discrimination in all educational ... |

| Ice jam data collection is necessary to gain information on ice jam events, which may occur rarely and are often short-lived, but can at the same time cause large damages. An ice jam data collection program involves field data collection, review of existing hydrologic, hydraulic, meteorological, and ice records, and a search of historical records that may pertain to ice events. This report describes the development of an ice jam ... |

| The city of Salmon, Idaho, is affected by flooding resulting from a frazil ice jam, known as the Deadwater jam, which forms annually on the Salmon River. Because the river has considerable environmental, economic, aesthetic, and recreational value, an innovative approach to frazil ice control is needed. The steep slope and turbulence of the river also add to ice control design constraints. Past investigations have examined a number of different ... |

|
| The intrinsic permeability of a frazil deposit can be used to describe its flow capacity and structure. Because of the nature of frazil ice, an in-situ test is desirable when determining this parameter in natural frazil deposits. This report describes the application of the borehole dilution test to determine seepage velocity, which is then used to calculate intrinsic permeability and estimate porosity. Seepage velocities ranged from 0.29 x 10-3 to ... |

| Frazil ice causes problems in many northern rivers. Frazil ice deposits can block intakes and hinder navigation and can result in ice jam flooding. Knowledge of the characteristics of a frazil ice deposit can aid in the design of ice control methods for that particular site. Unlike sheet ice, many of the physical characteristics of frazil ice deposits are not well known. Among these are hydraulic conductivity, intrinsic permeability and ... |
