From the ASCE On-Line Authors' Guide (revised):
References.In the text, cite publications by listing the last names of the authors and the year, which is called the author-date method of citation; e.g., (Duan et al. 1990; Frater and Packer 1992a). Prepare an appendix listing all references alphabetically by last name of the first author. For anonymous reports and standards, alphabetize by the issuing institution. Double-space the reference section.
Make sure reference information in the APPENDIX. REFERENCES is complete and accurate ... including as necessary and in the following order:

References must be inserted in the text at the place they are used, by the author's surname and year of publication. ... For references with more than two authors use the first author's surname followed by "et al" and, if there is more than one reference in the same year by a single author(s), use a, b. For example: (Roberts, 1981); (Roberts & Johnson, 1983); (Jones et al., 1986); (Johnson, 1998a, 1998b). ... All authors must be included in the reference list; "et al." is unacceptable here. ...Abbreviate journal names according to the Chemical Abstracts Service Source Index (CASSI).

From the ASME's Guidelines
Text Citation.Within the text, references should be cited in numerical order according to their order of appearance. The numbered reference citation should be enclosed in brackets.
Example: It was shown by Prusa  that the width of the plume decreases under these conditions.
In the case of two citations, the numbers should be separated by a comma [1,2]. In the case of more than two references, the numbers should be separated by a dash [5-7].
List of References.
References to original sources for cited material should be listed together at the end of the paper; footnotes should not be used for this purpose. References should be arranged in numerical order according to the sequence of citations within the text. Each reference should include the last name of each author followed by his initials.
(1) Reference to journal articles and papers in serial publications should include:
(2) Reference to textbooks and monographs should include:
(3) Reference to individual conference papers, papers in compiled conference proceedings, or any other collection of works by numerous authors should include:
(4) Reference to theses and technical reports should include:

This style is most commonly used in the humanities, particularly by fields that study literature and/or critical theory, such as English or comparative literature. The fields of art history, film/TV studies, and philosophy may use either MLA or Chicago.
MLA publishes two guides for writing and documenting research: the MLA Handbook for Writers of Research Papers, written for high school and undergraduate students, andthe MLA Style Manual and Guide to Scholarly Publishing, for graduate students, scholars, and professional writers.
The Chicago Manual of Style comprises two systems of citation: (1) the “humanities style” (notes and bibliography) and (2) the author-date system. Chicago is used by a wide assortment of fields, such as History, information science, and communications/journalism. However, fields that use Chicago may also use APA or MLA. Art history, classics, film/TV, and philosophy may employ either style.
The Chicago Manual of Style publishes a heavy hardcover book, The Chicago Manual of Style, and a CD-ROM. For a lighter tome, see Kate L. Turabian’s Manual for Writers of Research Papers, Theses, and Dissertations, which explains Chicago style and includes information about the research and writing process, punctuation, abbreviations, and the like.
The APA style is commonly used by fields in the social sciences such as psychology, linguistics, and education. APA publishes the Publication Manual of the American Psychological Association, a pocket guide, and instructor and student manuals.
Anthropology uses the style of the American Anthropological Association (AAA), which is based on the Chicago Manual of Style.
Chemists use the guidelines set forth by the American Chemical Society (ACS).
Civil Engineers often use the style set by the American Society of Civil Engineers (ASCE).
Another style is the Institute of Electrical and Electronic Engineers (IEEE) style.
Engineering also may use the ACS style.
The Association of American Geographers' publication refers to a citation style based on the Chicago Manual of Style.
Law uses the Bluebook style for citation.
American Mathematical Society (AMS) style. Other styles are acceptable so long as one style is consistent.
Various styles are used, including APA or Chicago, but the American Management Association also publishes a guidebook:
