IDF EXCEL DESIGN TOOL WITH MANUAL AND SAMPLE DATA

The IDF Rainfall Analysis Design Bundle is a professional-grade collection of Excel workbooks and reference guides built for civil engineers, urban planners, drainage consultants, and engineering students who need to develop Intensity–Duration–Frequency curves from scratch — using nothing but Microsoft Excel and real rainfall data.

The bundle delivers two complete design methodologies under one purchase: the Gumbel Extreme Value Type-I (EV-I) method and the CPHEEO Manual method. Both are fully operational, independently usable, and cross-referenced against Indian standards. Whether your project brief specifies one method or requires both for comparison, this bundle covers you completely.

Paired with two dedicated User Guides — one for each design sheet — this bundle gives you everything you need to understand, operate, and customise the analysis for any city, town, or IMD rainfall station in India.
