Considering the values of the water table depth at a particular well (we call this well the base well, hereafter) and the ones at any given well to be the two variables, the correlation coefficient (R) can be calculated. And if R is calculated for all wells in a given area (or a study area), the Equi-Correlation-Coefficient curves can be constructed on the map throughout the study area. Then, from these curves, the Equi-Correlation-Coefficient map of the water table can be drawn. This map suggests that the water table depth in most of the study area can be approximately estimated by using the data obtained from the base well.

Introduction When the volume of aquifer is measured for each month, a time series of the volume of aquifer is obtained. From this series, the aquifer's volume of increase during two consecutive months is obtained for the period of rise. And also, the volume of decrease is obtained for the period of decline. The values of the volumes of increase or decrease show a random variation in their time series. A study of the variations in the time series analysis was made.

1. Introbuction Because the temperature of water and soil directly effects the growth of cr6ps; it is important to know the temperature of water, including shallow groundwater, as well as to know its quantity. Therefore a lot of investigations have been undertaken concerning this problem. Some have tried to construct an equation to calculate the value of soil temperature. For example, AZUMA") constructed a linear equation to calculate the yearly average temperature of soil from the yearly average air temperature. We have tried here, however, to construct a linear equation calculating the value of shallow groundwater temperature near the water table from air temperature for a given area for a given month.

1, Introduction For practical purposes we often need to know the water-table depth for a given area for a given period. From an isobath map, we obtained the distribution curve showing the relationship between the water-table depth and its corresponding area. Applying the log-normal-probability-distribution equation, we obtained the theoretical equation to estimate the relation stated above. 2. Theory There is an isobath map consisting of n-class water-table depth, Di, D2, ... D, and the whole study area A. The relationship between the n-class water-table depth and its corresponding areas, al, a2, , a,„ are defined in Eq. (1).

No suitable method has yet been found for the study on the texture, the structure and the mineral composition of the deep weathered granites, which has been called the Masa. In this paper, it is reported that the writer has made the systematic study of the disintegrated and the weathered granites. Its method is the analysis of the relationship between the distance from the fault and the diameter of the particles, and also the analysis of the cumulative curve for the size distribution, the apparent specific gravity, the seismic sounding, the elect1' ic prospecting, the relief quantity. The area reseached by the writer covered nearly over the whole area of Rokko mountains, Hyogo Pref., Dogo Dist., Ehime Pref., Yashima, Kagawa Pref., Sanage Dist., Aichi Pref. and the other regions.

1. General Aspect of the Sen-En Area This report describes the general status of geology and underground water of the SenEn area which has made a remarkable industrial progress. The Sen-En Coastal Industrial Area locates in the plain overlooking the Pacific Ocean with Shiogama Port as its center. It includes Sendai City , Tagajo Town, Shiogama City, Shichigahama Village, Nanakita Village, etc. The geology of this area consists of Triassic Rifu formation and Neogene Tertiary in the hilly part, while in the plains it consists of Quaternary lowland deposit . Most of the industrial water is supplied by the deep underground water from Pliocene and Miocene sandstone and conglomerate. The writer would like to express his heart-felt thanks to the members of the Tohoku Boring Association (President—Mr. Masao Terashima) who were so generous in offering their cooperation toward this project. II. Outline of Geology and Hydrology Sendai-Shiogama coastal industrial area is divided into following 4 districts : ( 1 ) Sendai District : Nakae ; Nigat4ce ; Nagamachi Iwakiri areas ( 2 ) Tagajo District ( 3 ) Shiogama District ( 4 ) Yogasaki District 1. Sendai District : (a) Nakae area Terrace (Sendai Middle Terrace) area near the hills (Miocene Tsunaki formation) has a number of major and minor industries and hospitals such as Tobacco Manufacturing Factory of Japan Monopoly Corporation ; Municipal Coal Factory Kirin Beer Brewery ; Meiji Dairy Products Factory, Haranomachi Hospital ; Agricultural Experiment Station, etc., and most of them depend upon the water through the deep wells .
