Estimating Deep Percolation In The Mountain Rain-Snow Transition Zone, Patrick Richard Kormos

Boise State University Theses and Dissertations

Deep percolation (DP) is estimated from a small study catchment in the semi arid rain-snow transition zone in the foothills north of Boise, ID. A water balance is performed at the catchment soil bedrock interface, where soil drainage is assumed to be partitioned into DP and streamflow. While stream flow is measured, soil drainage must be estimated. We model the snow dynamics and surface water inputs (SWI) to the soil (Chapter 3), and the soil dynamics and soil drainage to the soil-bedrock interface (Chapter 4). The high spatiotemporal dataset used in this modeling effort is presented for the 2011 water …

Soil Building Processes In Reconstructed Tree Islands In The Everglades, Florida, Andres F. Rodriguez

FIU Electronic Theses and Dissertations

Soil building processes were studied in reconstructed tree islands in the Loxahatchee Impoundment Landscape Assessment, Florida. Soil building was evaluated by measuring litter production, litter decomposition, soil accretion, and changes in soil elevation under different hydrologic conditions, and by determining physicochemical characteristics of newly accreted soils. Tree islands showed higher litter production and soil accretion but a larger loss of soil elevation caused by subsidence at higher elevations and shorter inundation periods. Newly accreted soils exhibited higher nutrient concentrations, and organic matter (OM) than older soils. Most of the soil phosphorus was stored in the organic fraction. A positive correlation …

Inverse Method For Simultaneous Determination Of Soil Water Flux Density And Thermal Properties With A Penta-Needle Heat Pulse Probe, Changbing Yang, Masaru Sakai, Scott B. Jones

Plants, Soils, and Climate Faculty Publications

An accurate method for determination of in situ soil water flux density continues to be the most sought after and yet elusive hydrologic measurement. The penta-needle heat pulse probe (PHPP) employs a central heater needle surrounded by an orthogonal arrangement of four thermistor needles for two-component water flux density estimation. An analytical solution and inverse fitting method are presented for simultaneous estimation of thermal properties and soil water flux density using PHPP measurements. The approach yields estimates of both components of the flux in a plane normal to the axis of the PHPP needles. The method was evaluated using data …

Soil Groups Of Western Australia: A Simple Guide To The Main Soils Of Western Australia (4th Edn), Noel R. Schoknecht, Shahab Pathan

Resource management technical reports

This publication provides a simple, standardised and easy-to-understand way to recognise the most common soils in Western Australia.

It is designed to:

1) Provide a standard way of giving common names to the main soils of the State;

2) Provide a simple method to identify them;

3) Assist with the communication of soils information at a general level.
