Global Water Resource Data Archive


Introduction

In 2000, Mr. Saruhashi (Master course student in our labo) made his master thesis which deals global water resource. This archive contains his achievement (data, table and figures) as well as updated analysis results after his graduation.

Basically he calculated river discharge globally in 0.5degree x 0.5degree grid cells by using TRIP(river network dataset), STRIP( river flow calculation program using TRIP) and GSWP result of runoff from each grid cells.

Moreover, the withdrawal by agriculture, industry and urban life was estimated for 0.5*0.5 grid cells globally.

Then these two results are compared to investigate region where water resource is in high stress.

Moreover, using GCM x2CO2 experiment result and population growth scinario, the same estimation was performed for 2050 situation.

Original full text of his master thesis (in Japanese) is opened to public by PDF. But please be careful since the file size is more than 50MB...
