This manual provides guidance on estimating the energy potential of a hydropower site, selecting a project's installed capacity, determining the need for for the project's output, evaluating hydropower benefits, and estimating powerhouse costs.

This manual provides a general coverage of the field of ice engineering as it pertains to the responsibilities of the Corps of Engineers. For convenience, it is divided into three parts: first, Ice Properties, Processes, and Problem Solutions, second, Ice Jams and Mitigation Measures, and third, Winter Navigation on Inland Waterways. This manual does not address the environmental impacts of ice.

This engineer manual (EM) provides guidance for analyzing the static stability of slopes of earth and rock-fill dams, slopes of other types of embankments, excavated slopes, and natural slopes in soil and soft rock. Methods for analysis of slope stability are described and are illustrated by examples in the appendixes. Criteria are presented for strength tests, analysis conditions, and factors of safety. The criteria in this EM are to be used ...

The U.S. Army Corps of Engineers (USACE) conducts munitions responses under the Military Munitions Response Program (MMRP) in accordance with (IAW) the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). The guidance provided in this Engineer Manual (EM) applies to all USACE munitions response projects.

This United States Army Corps of Engineers (USACE) Engineer Manual (EM) 1110-1-4008 provides information for the design of liquid process piping systems.

This manual provides guidance on lubricants and hydraulic fluids to engineering, operations, maintenance, and construction personnel and other individuals responsible for the U.S. Army Corps of Engineers (USACE) civil works equipment.

This Engineer Manual (EM) establishes criteria and guidance for landfill off-gas collection and treatment systems.

In-situ air sparging (IAS) is a rapidly emerging remediation technology for treatment of contaminants in saturated zone soils and groundwater. Injection below the water table of air, pure oxygen, or other gases may result in removal of contaminants by volatilization or bioremediation. Less commonly, IAS can be used to immobilize contaminants through chemical changes such as precipitation. This Engineer Manual (EM) provides guidance for evaluat...

This manual provides practical guidance for the design and operation of soil vapor extraction (SVE) and bioventing (BV) systems. It is intended for use by engineers, geologists, hydrogeologists, and soil scientists, chemists, project managers, and others who possess a technical education and some design experience but only the broadest familiarity with SVE or BV systems.

The purpose of this manual is to provide detailed technical guidance and procedures for compliance with Engineer Regulation (ER) 1110-1-8156. The regulation establishes general criteria and presents policy and guidance for the acquisition, processing, storage, distribution, and utilization of nontactical geospatial data throughout the U.S. Army Corps of Engineers (USACE). Detailed technical guidance and requirements are stated, and standards f...

This manual presents procedural guidance, technical specifications, and quality control (QC) criteria for performing aerial photogrammetric mapping activities.

This manual provides guidance in the structural, mechanical, and electrical design of lock gates and operating equipment at navigation projects.

This manual provides guidance for the safe design and economical construction of retaining and flood walls. This manual is intended primarily for retaining walls which will be subjected to hydraulic loadings such as flowing water, submergence, wave action, and spray, exposure to chemically contaminated atmosphere, and/or severe climatic conditions. For the design of retaining walls which will not be subjected to hydraulic loadings or severe en...

This manual provides guidance on evaluating the condition of the concrete in a structure, relating the condition of the concrete to the underlying cause or causes of that condition, selecting an appropriate repair material and method for any deficiency found, and using the selected materials and methods to repair or rehabilitate the structure. Guidance is also included on maintenance of concrete and on preparation of concrete investigation rep...

This Engineer Manual (EM) document provides guidance and background for the appropriate screening and selection of in situ thermal remediation (ISTR) technologies, including steam enhanced extraction injection, electrical resistivity heating, and thermal conductive heating. This document is intended to help distinguish proper applications of the technology and identify important design, operational, and monitoring issues relevant to Government...

This manual identifies and analyzes generic safety and health standards for 25 remediation technologies used in clean-up operations at Hazardous, Toxic and Radioactive Waste (HTRW) sites throughout the country.

This manual provides guidance on performing detailed site surveys of military installation facilities and civil works projects. Technical specifications, procedural guidance, and quality control criteria are outlined for developing large-scale site plans used for engineering drawings of planned projects, or detailed as-built feature mapping of completed facilities.

This manual provides guidance for performance-based design and evaluation of concrete hydraulic structures (CHS). It introduces procedures that show how to design or evaluate a hydraulic structure to have a predictable performance for specified levels of seismic hazard. Traditional design and evaluation procedures may still be used for feasibility and screening purposes. However, for critical facilities, they should be followed by the procedur...
