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.

Evaluation of Relationships between Precipitation, Snow Depth, and Elevation
Author : Shuya KIKUCHI, So KAZAMA and Shoichi KUROSAWA
This paper described relationships between precipitation and snow depth, elevation. Therefore, we conducted 4 years assimilation method during September 2005 to August 2009 in the upper Iwaki catchment, Japan with SWE model. Furthermore, the runoff analysis shows high accuracy of river discharge in no-snowmelt season, but shows underestimation of river discharge in snowmelt season because of underestimation of the model driving spatial snowfall distribution. Moreover, the runoff model has the large error of peak discharge at some abrupt events, especially, snowmelt season. It is suspected that error of input snow water equivalent (SWE) data causes underestimation of flow volume. We estimate lack of SWE and relationships between precipitation and snow depth, elevation. As a result, lack of SWE has increased the higher snow depth and elevation.
