Abstract :From the writer's hydro-geological observations in the northeastern part of Ibaraki Prefecture together with the results of electric prospecting, the following features have become known: 1. Classification of drainage types (1) A-type, this is the wide drainage type and extends to the upper stream area. (2) B-type, this is the small drainage type and extends to the lower stream area. (3) C-type, this is an intermediate type of drainage, and is long and narrow in shape. 2. Horizons of water-bearing strata Shallow groundwater ( basal part of the Alluvial deposits /basal part of the Diluvial deposits ) Deep groundwater ( basal part of the Taga group / water bearing strata of the Yunagaya and Shiramizu groups) 3. Classification and character of the fossil valleys (1) The fossil valley on the erosion surface of the Hitachi Paleozoic rocks is more simple than those of the present valleys with which it is connected. At present the valleys are opened towards the Pacific Ocean. (2) The fossil valley
