FIELD HYDROLOGY INVESTIGATIONS FOR RIVER CROSSINGS

A COMPREHENSIVE FIELD INVESTIGATION IS A NECESSARY PREREQUISITE TO THE CONSTRUCTION OF A BRIDGE AT A RIVER SITE. SUCH ASPECTS AS TERRAIN, SOIL TYPES, RIVER CHARACTERISTICS, DEGRADATION AND EROSION AND DEPOSITION MUST BE CONSIDERED. INFORMATION CAN BE GAINED BY EXAMINING EXISTING BRIDGES. THE FLOOD-WATER-LINE AS WELL AS ANY DAMAGE DUE TO ICE OR DEBRIS JAMS WILL BE EVIDENT. FURTHER INFORMATION MAY BE GATHERED FROM INTERVIEWS WITH LOCAL RESIDENTS WHO MAY BE AWARE OF A RIVERS PECULIARITIES WHICH ARE NOT EVIDENT FROM SOIL INVESTIGATIONS. AERIAL PHOTO- GRAMMETRY MAY ALSO BE AN ASSET IN DETERMINING A RIVERS FORMER BED OR CURRENT CHARACTERISTICS. /CGRA/RRL/
