"BREAKING THE HEC-RAS CODE"

This book covers one of the most powerful, yet relatively unknown features available in HEC-RAS: the HECRASController! The HECRASController API has a wealth of procedures which allow a programmer to manipulate HEC-RAS externally by setting input data, retrieving input or output data, and performing common functions such as opening and closing HEC-RAS, changing plans, running HEC-RAS, and plotting output. A companion Excel workbook provides VBA code that demonstrates the HECRASController subroutines and functions.
