The manual provides a general overview of groundwater principles. Practical discussions are provided for planning groundwater investigations and modeling of groundwater flow. Additionally, a section on surface water and groundwater interaction is included. To enhance understanding of concepts, examples are provided throughout the manual. This manual initially presents an overview of the occurrence and movement of groundwater. Procedures for planning and managing a site characterization and modeling study are then presented. This is followed by chapters addressing the technical aspects of...

The purpose of this manual is to provide technical criteria and guidance for the planning and design of concrete gravity dams for civil works projects. This manual presents analysis and design guidance for concrete gravity dams. Conventional concrete and roller compacted concrete are both addressed. Curved gravity dams designed for arch action and other types of concrete gravity dams are not covered in this manual. Basically, gravity dams are solid concrete structures that maintain their stability against design loads from the geometric shape and the mass and strength of the concrete....

This manual provides (a) guidance on the design and construction of conduits, culverts, and pipes, and (b) design procedures for trench/embankment earth loadings, highway loadings, railroad loadings, surface concentrated loadings, and internal/external fluid pressures. Reinforced concrete conduits and pipes are used for dams, urban levees, and other levees where public safety is at risk or substantial property damage could occur. Corrugated metal pipes are acceptable through agricultural levees where conduits are 900-mm (36-in.) diameter and where levee embankments are not higher than 4 m (12...

All hydraulic projects subjected to freezing temperatures have ice problems, such as: ice buildup on lock walls, hydropower intakes, and lock approaches; ice accumulation in navigation channels; ice passage over spillways that scours the downstream channels; and ice damage to shore structures and shorelines, etc. Therefore, ice control measures should be considered for both new and existing projects to improve operations and safety in cold regions. In Part I, this manual contains a discussion of ice formation processes, physical properties, and potential solutions to associated problems. Part...

This manual describes available or preferred procedures or concepts of drilling and blasting conducted during rock excavation, in order to aid design and construction personnel in related matters. The manual is designed principally for the use of geologists and engineers who are given responsibilities in drilling and blasting projects. Such responsibilities may come either in the design or the construction phase. Contents: Introduction Mechanics of Blasting Explosives and their Properties Drilling Basic Surface Blasting Techniques Modifying Blasting Techniques to Fit Geological Conditions...

The primary purpose of this manual is to provide practical guidance for removal of underground storage tanks. The manual addresses site evaluation, monitoring, testing, removal, and site restoration. A secondary purpose is to provide information relative to remediation of contaminated soil and groundwater.

This manual provides current guidance and engineering procedures for the solution of tidal hydraulics problems. The subjects covered in this manual range from the fundamentals of estuarine engineering to specific problem solving techniques, including environmental considerations, to a summary of "lessons learned" from completed projects. The problem solving portion of the manual serves as a means of transferring the technical knowledge obtained from recent research efforts in tidal hydraulic engineering.
