A COMPUTERIZED GROUND-WATER RESOURCES INFORMATION SYSTEM

Abstract. The MCGRIB system is a computerized data base of hydrogeologic information recorded in drillers' logs. It also includes software that allows the user to display hydrogeologic data for any specified area in tabular or map form. Although the system is designed mainly for glaciated regions it can be adapted to almost any geologic setting. The main advantages of the system are that it can be updated regularly and can rapidly provide pertinent information about subsurface hydrogeologic conditions.

THE USE OF ENTROPY IN HYDROLOGY AND WATER RESOURCES

Since the development of the entropy theory by Shannon in the late 1940s and of the principle of maximum entropy (POME) by Jaynes in the late 1950s there has been a proliferation of applications of entropy in a wide spectrum of areas, including hydrological and environmental sciences. The real impetus to entropy-based hydrological modelling was provided by Amorocho and Espildora in 1972. A great variety of entropy applications in hydrology and water resources have since been reported, and new applications continue to unfold. This paper reviews the recent contributions on entropy applications in hydrology and water resources, discusses the usefulness and versatility of the entropy concept, and reflects on the strengths and limitations of this concept. The paper concludes with comments on its implications in developing countries. © 1997 by John Wiley & Sons, Ltd.

A NATIONAL SYSTEM FOR EXCHANGE OF WATER DATA

ABSTRACT

This paper describes a system proposed by a Federal Interagency Work Group for providing access to large quantities of hydrological data. The National Water Data Exchange (NAWDEX) will be a confederation of data-acquisition organizations that are willing to make their data available to other data users. NAWDEX will take full advantage of on-going data handling activities and will provide the means to present data in a standard format. An ultimate goal of the system will be standardization and quality control of all of the data. Management of NAWDEX will be lodged in a Systems Central, which will assure that data are made available according to the time frame and the format required by the user. Access to the data will be through an index maintained by Systems Central. Full implementation of NAWDEX will require 4 to 5 years. A technical advisory group, consisting of members representing the Federal and non-Federal sectors, and topical work groups, established in response to specific needs, will provide input during the development of NAWDEX.     

地震学情报数据库研究

将国内出版的地震学期刊论文,建立一个联机检索数据库。使用VAX11/750小型计算机和VAX DTR、CDD软件,操作系统是VAX/VMS。地震期刊论文数据库分成二个数据库,题录数据库和论文文摘数据库。它们是文件结构型数据库。一条题录记录占339字节,一条论文文摘记录占1290字节。自行编制设计了人机对话式联机检索程序。用户使用感到十分简便。论文追溯时间计划为十年或更长一些。     

CSAMT法和高密度电法探测地下水资源

我国乃至世界目前都面临着严重的水资源的短缺，利用新技术、新方法合理勘探开发并利用水资源，是经济腾飞的关键。本文概述了CSAMT方法和近几年来发展起来的高密度电阻率找水方法，列举了两种方法应用的的实例。实践表明这两种方法是水资源勘查的有效手段。
