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....

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...

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...

A Method for `Warped Surface' Land Forming Design
Most approaches to land forming are based on a plane surface design which in some cases may result in prohibitive costs or excessive removal of top soil....

A Portable Bowen Ratio System for ET Measurements
The AZET system developed at the University of Arizona is designed to measure evapotranspiration (ET) in arid zone environments, using the Bowen ratio model. The system consists of a set...

Selenium in the Kendrick Reclamation Project, Wyoming
Elevated concentrations of selenium in water, bottom sediment, and biota were noted during a reconnaissance investigation of the Kendrick Reclamation Project in central Wyoming. Dissolved-selenium...

Water Quality Modeling Using a Small Watershed Model (SWAM)
The Small Watershed Model (SWAM) is a state-of-the-art model that simulates the movement of water, sediment, and chemicals through a small, mixed-land-use watershed. It was developed to...

Garbage Management in Japan: Leading the Way
Excerpts from a book that details how land-poor Japan has less garbage problems than the land rich United States. Chapter Six, Incineration, is excerpted. In Japan, incineration is regarded...

Bureau of Reclamation's High Plains States Ground Water Recharge Program
The Bureau of Reclamation is conducting a two-phase program to demonstrate the feasibility of recharging declining aquifers in the 17 western states. The U.S. Geological Survey (USGS),...

Ground Water Recharge and Management Under the Small Reclamation Projects Act
The U.S. Bureau of Reclamation through its Small Reclamation Loan Program is providing needed Federal financial and technical assistance to water users in Southern California to help ease...
