IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Mapping flood dynamics using wireless communicable gps receivers
Author : CHANJOO LEE(1), WON KIM(2) & DONGGU KIM(3)
ABSTRACT
Recent field measurement on flow dynamics seems to be geo-referenced. ADCPs equipped with precise GPS are such
devices that give flow distribution data on real rivers. However, they have limitations probably because they are not so
capable in severe flow condition like flood. This study provides devices more convenient and easily usable. Wireless
communicable GPS rovers are provided with a portable base station composed of RF receivers of three different
frequencies. Using this system, we could obtain the flow field along the river channel during the low and high flow
conditions. Location and time data were gained to be converted to get velocity data. After grid-based interpolation, twodimensional
flow field of the rivers were given. Possible application is addressed.
