Debris Flow Hazard Assessment for the Oregon Caves National Monument (open access)

Debris Flow Hazard Assessment for the Oregon Caves National Monument

From introduction: Of the various hydrologic hazards in our environment, the mass movement of earth material caused by excess moisture can be one of the most destructive. These events often go unnoticed because they occur in unpopulated mountainous terrain during winter seasons. This was not the case in December 1964, when a major debris flow occurred in the Cave Creek drainage of the Oregon Caves National Monument. In March 1982, the National Park Service (NPS) requested a study be made to appraise the possibility of a recurrence of the 1964 debris flow in the interest of safeguarding the public and employees of the National Park Service.

Deprivation of Equations Describing Solute Transport in Ground Water (open access)

Deprivation of Equations Describing Solute Transport in Ground Water

Abstract: A general equation describing the three-dimensional transport and dispersion of a reacting solute in flowing ground water is derived from the principle of conservation of mass. The derivation presented in this report is more detailed but less rigorous than derivations published previously. The general solute-transport equation relates concentration changes to hydrodynamic dispersion, convective transport, fluid sources and sinks, and chemical reactions. Because both dispersion and convective transport depend on the velocity of ground-water flow, the solute-transport equation must be solved in conjunction with the ground-water flow equation.
