A Laboratory Characterization Of Pulp And Paper Mill Solid Wastes For Potential Use As Hydraulic Barrier Material In Landfill Covers, Carleton Van Maltby Jun 1989

A Laboratory Characterization Of Pulp And Paper Mill Solid Wastes For Potential Use As Hydraulic Barrier Material In Landfill Covers, Carleton Van Maltby

Masters Theses

Fifteen sludges from wastewater treatment systems of pulp and paper mills that encompass major production categories, and eight fly ashes from mill boilers incinerating wood waste, coal, or their combination were characterized for their potential suitability as hydraulic barrier material. Hydraulic conductivity was observed to range over four orders of magnitude for the materials tested.


Some Hydrologic Aspects Of Snowmelt Runoff Under Summer Conditions, In The Barpu Glacier Basin, Central Karakoram, Himalaya, Northern Pakistan, Ali Ghazanfar Jan 1989

Some Hydrologic Aspects Of Snowmelt Runoff Under Summer Conditions, In The Barpu Glacier Basin, Central Karakoram, Himalaya, Northern Pakistan, Ali Ghazanfar

Theses and Dissertations (Comprehensive)

Snow and ice in high mountains represent and important water resource in many parts of the world, especially the dry continental interior of Central Asia. In the Northern Areas of Pakistan, mountain ranges are the primary sources of annually renewed water supplies.

The Indus basin is drained by the river Indus and its major tributaries, the Kabul, Jhelum, Chanab, Ravi and Sutlej. Snowmelt contributes about 70 percent to the annual flow of these rivers, but is not timed to meet the requirements for crop production, …

Environmental Planning Of Large-Scale Water Projects: The Three Gorges Dam Case, China, Long Li Jan 1989

Environmental Planning Of Large-Scale Water Projects: The Three Gorges Dam Case, China, Long Li

Theses and Dissertations (Comprehensive)

Controversy over the construction of the Three Gorges Dam across the Yangtze River in China is an on-going national issue. Proposals have been advanced by numerous disciplinary research teams to identify the environmental consequences of the project development. However, whether the project will benefit or damage the overall environment still remains in question.

No matter which one of the four storage schemes is going to be put into operation, the human, economic, biological, and physical environmental alterations will have no equal in the our contemporary world and probably even for some time in the future. Above all, flood control, hydro-electricity …
