Erosion from an Industrial Forest Road in the Ouachita Mountains of Southeastern Oklahoma
Erosion from 4 segments of a 2-year old forest road in a 740 ha basin was measured for each of 105 storms that occurred in a 3.5 year period. Two road segments were part of a mid-slope...
Structural Lumber from Small-Diameter Western U.S. Softwood Trees
The purpose of this study was to determine the mechanical properties, and corresponding economic value, of dimension lumber produced from selected over-stocked forest stands of small-diameter...
Small-Diameter Round Timber Connections
An over stocking of trees having diameters less than 20 cm, as measured 1.52 m off the ground presents a major fire hazard to over 54 million acres of National Forest land. Improving the...
Recycling Penn Forest Dam
Almost since it's construction more than 30 years ago, the Penn Forest Dam had suffered severe seepage, leading officials in Bethlehem, Penn., to wonder how secure their largest...
A Mechanism of Pool Formation and Maintenance in Forest Streams
Laboratory and field investigations illustrate a hydraulic mechanism responsible for the formation and maintenance of pools associated with large, in-channel obstructions in forest streams....
The Flood Threat Response in South Louisiana
The flood threat to the people of Louisiana is ever present. Responses to reducing the flood threat have been relocation, structural and regulatory. All of these responses effect the surrounding...
Predicting Effects of Modifying Tussock Grassland
Measurements of rainfall, drainage, and weight change of a 6 m2 surface area cylindrical lysimeter containing nine snow tussocks (Chionochloa rigida)...
Effects of Fine Sediment Intrusion on Spawning Gravel in Southeast Alaska
The supply of sediment to forest streams in Southeastern Alaska is related to the inherent instabilities of landforms, stream channels and the effects of logging practices. Debris avalanches,...
Hydraulic Roughness and Sediment Yield in Wheel Ruts on Forest Roads
Clear water flow and sediment yield from simulated wheel ruts in a forest road were measured at five different sites in the Northern Rocky Mountains. These measurements provided information...
Dissolved Oxygen and Woody Debris: Detecting Sensitive Forest Streams
Early watershed studies showed that timber harvesting and yarding could depress dissolved oxygen in nearby streams when fresh slash entered streams and streamside shade was reduced. State...
Effects of Forest Cover on a Snowpack in the Sierra Nevada
Adjacent snowpacks in a clearing and under a forest canopy were compared over a decade at a site near Lake Tahoe. This comparison provides a few indications of the differences in snowpack...
Procedures Used for Determining Water Rights on the Caribbean National Forest
In response to increasing demand, the Commonwealth of Puerto Rico enacted legislation requiring current users of water to file existing water uses. Application for water rights on the...
Methods for Assessing Wood Structures in Place
The Forest Products Laboratory is developing a comprehensive guideline for assessing the condition of existing wood structures. This paper provides an overview of the current literature...
Watershed Planning and Analysis in Action
This proceedings consists of papers presented at the 1990 Watershed Management Symposium held in Durango, Colorado from July 9-14, 1990. These papers present both research performed in...
Retaining Forest Roads
The U.S. Department of Agriculture, Forest Service, manages a vast system of roads which provide access to America's national forests. More than 250,000 miles of roads exist...
Applications and Research in Sediment Delivery and Routing Models in the USDA-Forest Service
Sediment delivery and routing are important watershed management issues in the USDA-Forest Service. The relationship between forest management activities and stream morphology, resident...
Soil Erosion and Sediment Transport Modeling on Small Tropical Watersheds
A fundamentally-based concept of a soil erosion and sediment transport model in a forest tropical area is presented. It will be incorporated to the ANSWERS model. The forest hydrology...
Energy from the Amazon
Cadman describes Brazil's plans for exploiting the vast hydroelectrical potential of the Amazon Basin, placing them within the context of the country's growing...
Development of Hydropower Projects on National Forest System Land
The United States Department of Agriculture Forest Service has a major role in hydroelectric developments on National Forest System land. It is charged with managing the land for multiple...
Properties of Tin-Mined Land in Mangrove Forest, Thailand
Although mangrove forests occupy a very small area of Thailand, they contribute not only an ecosystem but also large tin ore deposits. Two provinces in the South, Ranong and Phangnga,...
