Engineering Answers to Groundwater Impact Questions Using a Geographic Information System (GIS)
Environmental concerns have raised complex questions about the impacts of increased groundwater levels adjacent to navigational pools along the Red River, Louisiana. Previous studies had...

Seven Legal Strategies to Cool Global Warming
The author holds that there are seven types of legal approaches which can be employed by different levels of government to cool global warming. Application of these strategies, singly...

Importance of the Tropical Rainfall Measuring Mission (TRMM) Satellite to Hydrological Investigations
Rainfall over the global tropics is crucial to the global hydrological cycle and to water resources in most developing countries. Its magnitude and variations are presently poorly known....

Introduction to Remote Sensing for Irrigation and Drainage
Remote sensing is a rapidly emerging technology that has many potential applications to irrigation, drainage and hydrologic engineering. This paper, the first of four, introduces the reader...

Applications of Remote Sensing to Hydrology
This paper pulls together examples of current applications of remote sensing information to hydrology. Topics covered include rainfall, snow hydrology, soil moisture, evapotranspiration,...

Applications of Remote Sensing to Irrigated Agriculture
Several uses for satellite digital imagery and data from portable field radiometers have been developed for the monitoring of agricultural crops, their yields, insect and disease attacks,...

United States Metrication and the EC 92
Major Congressional legislation adopted in 1988 was related to USA trade and competitiveness problems of the Nation. The legislation contained a section on metrication that required all...

Metrication of Construction?A Message to the American Society of Civil Engineers
The author discusses the reasons for metrication of the U.S. construction industry, describes the Canadian experience in this area, and outlines the necessary steps to alleviate the metrication...

Metrication Between Canada and the USA?A Staged Adoption
Great Britain has led the way for change from English to metric units. There, as in the United States, industry and trade were the motivating forces for change. The gradual change to metric...

ET from Shallow Groundwater Maintained by Controlled-Drainage/Subirrigation System
Soil-water management by maintaining a shallow groundwater level (watertable) via a dual purpose subdrainage-subirrigation system, is becoming popular in humid regions of the United States...
