Sensing by Satellite
Commercially available data collected by U.S. and French satellites re helping civil engineers take a closer look at our planet. Also available are PC-based image processing systems that...
Highway Damage Due to Subsidence
In this study subsidence profiles over three longwall panels, which were mined beneath state highways in Southeastern Ohio, were obtained. Immediate and short term subsidences were recorded....
Subsidence Abatement Projects in Wyoming?An Overview
Abatement projects were undertaken to prevent or minimize further subsidence in Wyoming communities. The paper gives a brief historical background on the mining activity in Wyoming. Subsidence...
Subsidence Control by High Volume Grouting
Mine grouting programs generally fall into two general methods: flushing and grout columns. With the flushing method, the entire mine under the area to be protected is filled. Grout columns...
Coal Mine Subsidence and Structures
Underground coal mining has occurred beneath 32 multiplied by 10**9m**2 (8 million acres) of land in the United States and will eventually extend beneath 162 multiplied by 10**9m**2 (40...
Mining Subsidence Effects on Transportation Facilities
This paper presents case history information about mining subsidence effects on transportation facilities, including bridges, pavements, and culverts. Most of the field observations pertain...
A Review of Some Aspects of Grouting for Mine Subsidence Control
This paper presents an overview of the state-of-the-art of grouting as a technique for mine subsidence control. A review of some aspects of grouting theory is presented, and illustrative...
Subsidence Over AML and Its Causes?A Case Study
Subsidence over abandoned mined lands can be attributed to several causes. For purposes of compensation and liability and developing remedial measures, it is essential to identify the...
Mechanisms of Subsidence Induced Damage and Techniques for Analysis
Structural damage due to mining induced subsidence is a function of the nature of the structure and its position on the subsidence profile. A point on the profile may be in the tensile...
Review of Subsidence and Stabilization Techniques
Currently, in Britain, the mining industry is undergoing a state of decline for economic reasons. Consequently, the number of old coal sites available for development schemes has increased....
An Analysis of Hourly Water Use in Austin, Texas
While it is possible to calculate water use over a fairly short period of time, this only yields a single value for peak use. It does not give a comprehensive understanding of the frequency,...
IWR-Main?Version 5.1?An IBM-PC or Compatible Water Use Forecasting System
The IWR-MAIN water use forecasting system is a sophisticated and flexible computer program designed for estimating and forecasting municipal water requirements. The IWR-MAIN system is...
Water Supply Critical Areas
Due to the serious overuse of groundwater resources which has led to the continued decline of the potentiometric surface of certain aquifers below sea level, and to real and potential...
Master Plan of a Reclaimed Water System
Arizona cities are under a state mandate to reduce water consumption as a result of the 1980 Arizona Groundwater Management Act. Since reclaimed water use is not included in the overall...
Conflict Management Task Committee Approach
The Task Committee on Conflict Management (coordinated by the Social and Environmental Objectives and Impacts Committee, WRPMD), was established to develop guidelines for use by water...
Water Demand Forecasting in Southern California
A study of annual water use in Southern California is made in order to determine the cause of unusually high demands in 1987. Regression analysis of the demands and analysis of ratios...
Risk Assessment of Lake Shore Development of Devils Lake, North Dakota
In recent years, the advent of the flood insurance programs has forced developers, financiers, and planners to deal with future high water conditions and associated risks. A reliable method...
Traffic Jams on Main Street
Traffic congestion in suburban areas has become a leading public concern prompting a renewed search for transportation and land use strategies to help relieve congestion. Causes of traffic...
Mine Induced Subsidence
Effects on Engineered Structures
The influence of mine subsidence on engineered structures is a growing concern of the United States coal industry. This book contains a collection of case histories of the control and...
Simple Furrow Advance Ratio Evaluation Technique for Upgrading Management
A simple procedure using the Advance Ratio (AR) is presented. It utilizes on-farm gathered information of advance time, water application time, and depth applied for furrow irrigated field....
