I. Evolution & Technical Manuals

• 2010: Manual for Coastal Protection and Environmental Restoration Planning
• 2011: Operational Manual (Draft) for Coastal Ecological Habitat Assessment and for Developing Engineering Impact-Mitigation Measures or Alternatives
• 2012: Technical Manual for Coastal Protection and Eco-Engineering (Draft; with CD)
• 2014 — approved by WRA: Reference Manual for Basic Data Observation and Investigation in Coastal Protection Planning (General Seawalls)

II. Purpose & Scope of the 2014 Reference Manual

• Purpose: To establish clear and unified items, methods, and requirements for basic data observation and investigation in coastal protection planning; to obtain high-quality disaster-prevention/mitigation data; and to build a basic database for general seawalls as a basis for planning, design, and construction.
• Scope: Applicable to the WRA and its subordinate agencies for basic data observation and investigation related to coastal protection works and planning within their jurisdictions.
• Workflow: Conducted in accordance with the manual (see Fig. 1).

III. Current Data Volume (Total 9,255 records)
