Guidelines and Standard Procedures for Continuous Water-quality Monitors


Book Description

The U.S. Geological Survey uses continuous water- quality monitors to assess the quality of the Nation's surface water. A common monitoring-system configuration for water-quality data collection is the four-parameter monitoring system, which collects temperature, specific conductance, dissolved oxygen, and pH data. Such systems also can be configured to measure other properties, such as turbidity or fluorescence. Data from sensors can be used in conjunction with chemical analyses of samples to estimate chemical loads. The sensors that are used to measure water-quality field parameters require careful field observation, cleaning, and calibration procedures, as well as thorough procedures for the computation and publication of final records.




Statistical Methods in Water Resources


Book Description

Data on water quality and other environmental issues are being collected at an ever-increasing rate. In the past, however, the techniques used by scientists to interpret this data have not progressed as quickly. This is a book of modern statistical methods for analysis of practical problems in water quality and water resources. The last fifteen years have seen major advances in the fields of exploratory data analysis (EDA) and robust statistical methods. The 'real-life' characteristics of environmental data tend to drive analysis towards the use of these methods. These advances are presented in a practical and relevant format. Alternate methods are compared, highlighting the strengths and weaknesses of each as applied to environmental data. Techniques for trend analysis and dealing with water below the detection limit are topics covered, which are of great interest to consultants in water-quality and hydrology, scientists in state, provincial and federal water resources, and geological survey agencies. The practising water resources scientist will find the worked examples using actual field data from case studies of environmental problems, of real value. Exercises at the end of each chapter enable the mechanics of the methodological process to be fully understood, with data sets included on diskette for easy use. The result is a book that is both up-to-date and immediately relevant to ongoing work in the environmental and water sciences.







The Old Federal Road in Alabama


Book Description

A concise illustrated guidebook for those wishing to explore and know more about the storied gateway that made possible Alabama's development Forged through the territory of the Creek Nation by the United States federal government, the Federal Road was developed as a communication artery linking the east coast of the United States with Louisiana. Its creation amplified already tense relationships between the government, settlers, and the Creek Nation, culminating in the devastating Creek War of 1813–1814, and thereafter it became the primary avenue of immigration for thousands of Alabama settlers. Central to understanding Alabama’s territorial and early statehood years, the Federal Road was both a physical and symbolic thoroughfare that cut a swath of shattering change through the land and cultures it traversed. The road revolutionized Alabama’s expansion, altering the course of its development by playing a significant role in sparking a cataclysmic war, facilitating unprecedented American immigration, and enabling an associated radical transformation of the land itself. The first half of The Old Federal Road in Alabama: An Illustrated Guide offers a narrative history that includes brief accounts of the construction of the road, the experiences of historic travelers, and descriptions of major changes to the road over time. The authors vividly reconstruct the course of the road in detail and make use of a wealth of well-chosen illustrations. Along the way they give attention to the very terrain it traversed, bringing to life what traveling the road must have been like and illuminating its story in a way few others have ever attempted. The second half of the volume is divided into three parts—Eastern, Central, and Southern—and serves as a modern traveler’s guide to the Federal Road. This section includes driving tours and maps, highlighting historical sites and surviving portions of the old road and how to visit them.
