Organization, Financing, and Administration of Drainage Districts

Description: "This bulletin is prepared to aid landowners, district officials, and others interested in forming drainage districts for the purpose of reclaiming swamp and overflowed lands. It presents methods of organizing the interested property owners and principles which should be considered in the administration and financing of drainage districts. It is particularly applicable to drainage districts in the humid regions of the United States. Because the laws in no two states are exactly alike, the subject necessarily must be treated in a general way." -- p. 3

Trenching Machinery Used for the Construction of Trenches for Tile Drains

Description: "This bulletin describes the types of trenching machines, and discusses the limiting conditions of work and the cost of trenching.... It will be of service to those whose lands need tile drainage. It does not deal with the drainage of irrigated lands, where the requirements for good trenching machines are often unusual and the cost of work much greater." -- title page

Mine Pumping Plants: Anthracite Region of Pennsylvania

Description: From Summary: "To obtain a reliable picture of the anthracite-mine-water problem and to solve that problem, it is necessary to have factual data on the volume and the quality and character of mine water handled by pumping plants in the anthracite region, as well as kinds of pumps utilized and problems concerning their operation. The main conclusion that be drawn from an investigation of drainage practices in the anthracite region is that, although efficient pumping layouts, tunnels for draining active mines, and large-scale surface-drainage facilities for keeping water out of mines are in use, the anthracite industry still is threatened with curtailment, to a major degree, and premature extinction because of the encroachment of water, unless remedial action is undertaken in the vary near future by all interests concerned."

DISPOSAL OF FLUIDIZED BED COMBUSTION ASH IN AN UNDERGROUND MINE TO CONTROL ACID MINE DRAINAGE AND SUBSIDENCE

Description: This project will evaluate the technical, economic and environmental feasibility of filling abandoned underground mine voids with alkaline, advanced coal combustion wastes (Fluidized Bed Combustion-FBC ash). Success will be measured in terms of technical feasibility of the approach (i.e. % void filling), cost, environmental benefits (acid mine drainage and subsidence control) and environmental impacts (noxious ion release). This document reports on progress made during Phase III. The report is divided into three major sections. The first deals with the Hydraulic Injection component. This section of the report describes the progress and milestones associated with the grouting activities of the project. The Phase III tasks of Economic Analysis and Regulatory Analysis is covered under this section. The second component is Pneumatic Injection. This section reports on progress made towards completing the demonstration project. The last component involves evaluating the migration of contaminants through the grouted mine. A computer model has been developed in earlier phases and will model the flow of water in and around the grouted Longridge mine.

Hygric Redistribution in Insulated Assemblies: Retrofitting Residential Envelopes Without Creating Moisture Issues

Description: The Building America program has recognized that most of the current housing stock is in need of energy related retrofits. One of the best ways of reducing the space conditioning energy consumption is to improve the thermal performance of the enclosure by adding exterior board foam insulation. This report quantifies the amount of water that can become trapped in the drainage cavity of typical wall systems, and measures the effect of water trapped in the drainage cavity on the moisture content of the sheathing. This study also attempts to explain the discrepancy between hygrothermal simulations and field performance of low permeance, low R-value exterior insulation (e.g. 3/4-in. foil faced polyisocyanurate) in cold climates.

Drainage and Erosion Control Facilities: Field Performance Investigation

Description: Partial summary: "The drainage and erosion control facilities of 54 installations were observed to evaluate performance of surface and subsurface drainage systems, erosion control measures, and conditions of buried conduits and associated facilities. Although the facilities observed varied from only 1 to 30 years or more of age and it is recognized that basic demands have increased as well as the fact that design and construction procedures have been improved continuously, many of the old familiar problems still exist and a few new ones have developed" (p. xi).

Description: From Summary: "This report covers the second in a series of five projects into which the Conowingo tunnel system has been divided for geographical and practical reasons. It outlines the construction work contemplated-to sink two shafts on the line of the main tunnel that are designated the Nos. 9A and 11 shafts, to turn off from the No. 9A shaft the Landsford and Lykens laterals, and to drive portions of the main tunnel."

Disposal of Fluidized Bed Combustion Ash in an Underground Mine to Control Acid Mine Drainage and Subsidence

Description: This project will evaluate the technical, economic and environmental feasibility of filling abandoned underground mine voids with alkaline, advanced coal combustion wastes (Fluidized Bed Combustion (FBC) ash). Success will be measured in terms of technical feasibility of the approach (i.e. YO void filling), cost, environmental benefits (acid mine drainage and subsidence control) and environmental impacts (noxious ion release). During Phase Ill the majority of the activity involves completing two full scale demonstration projects. The eleven acre Longridge mine in Preston County will be filled with 53,000 cubic yards of grout during the spring of 1998 and monitored for following year. The second demonstration involves stowing 2000 tons of ash into an abandoned mine to demonstrate the newly redesigned Burnett Ejector. This demonstration is anticipated to take place during the winter of 1997. This document will report on progress made during Phase Ill. The report will be divided into four major sections. The first will be the Hydraulic Injection component. This section of the report will report on progress and milestones associated with the grouting activities of the project. The Phase Ill tasks of Economic Analysis and Regulatory Analysis will be covered under this section. The second component is Pneumatic Injection. This section reports on progress made towards completing the demonstration project. The Water Quality component involves background monitoring of water quality and precipitation at the Phase Ill (Longridge) mine site. The last component involves evaluating the migration of contaminants through the grouted mine. A computer model has been developed in earlier phases and will model the flow of water in and around the grouted Longridge mine.

Real-Time Water Quality Monitoring and Habitat Assessment in theSan Luis National Wildlife Refuge

Description: The project report describes a two year experiment to control wetland drainage to the San Joaquin River of California from the San Luis National Wildlife Refuge using a decision support system for real-time water quality management. This system required the installation and operation of one inlet and three drainage flow and water quality monitoring stations which allowed a simple mass balance model to be developed of the seasonally managed wetlands in the study area. Remote sensing methods were developed to document long-term trends in wetland moist soil vegetation and soil salinity in response to management options such as delaying the initiation of seasonal wetland drainage. These environmental management tools provide wetland managers with some of the tools necessary to improve salinity conditions in the San Joaquin River and improve compliance with State mandated salinity objectives without inflicting long-term harm on the wild fowl habitat resource.

Effect on Sediment Yield and Water Quality of a Nonrehabilitated Surface Coal Mine in North-Central Wyoming

Description: From introduction: The purpose of this study was to determine the magnitude of some effects of an abandoned surface coal mine on the hydrologic environment. Specific objectives were (1) to define areas of erosion and deposition; (2) to determine if the sediment yield from an undisturbed drainage basin was less than that from a drainage basin partly disturbed by mining activity; and (3) to determine if there were differences in chemical composition of hillslope materials, sediment, and pond water in the two basins.
