Fate of TCE in Phytoremediation Systems
The phytoremediation of trichloroethylene (TCE) and other volatile organic compounds (VOCs) has been developed from a mere concept to full applications over the past decade. However, the...

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)...

Transpiration by Douglas Fir Using Lysimeters
During the spring of 1971 a 28 m Douglas fir tree was installed in a weighing lysimeter. Some details of construction are presented. The weighing mechanism consisted of eleven lengths...

Lysimetry for Evaporation and Transpiration Measurement
Large hydraulically weighed lysimeters were used to measure evapotranspiration (ET), evaporation (E), and transpiration (T). Weighing lysimeters for T measurements were covered to suppress...

Crop Yield Models Adapted to Irrigation Scheduling Programs
A crop yield model (CRPSM) was adapted to match the data obtained with typical irrigation scheduling programs. Daily soil water content was calculated from weather data, crop growth stage...

Predicting Radon Transport by Vegetation
Establishment of a vegetative cover on waste sites containing **2**2**6Ra (Radium) may provide conduits for transport of **2**2**2Rn (Radon) out of the waste into the above-ground environment...

Modelling Transpiration of Subalpine Trees in the Central Rocky Mountains
Forest evapotranspiration (ET) has long been recognized to be a major component in the mass water balance of subalpine watersheds in the central Rocky Mountains. In recent years, research...

Daily Trends in Soil Evaporation and Plant Transpiration for Irrigated Corn

Desiccation and Consolidation of Dredged Materials
A mathematical model, which numerically solves the boundary value problem representing these physical phenomena, is applied in conjunction with the results of an extensive experimental...

Simulation of Post-Irrigation Moisture Movement
The transpiration-induced moisture removal by the plant roots is represented by a negative source term in the Darcy equation. When the soil is wetted to near saturation, the moisture flow...

Mechanics of Evapo-Transpiration
Fundamental mechanisms involved in transpiration and evaporation are analyzed; manner in which physical factors in these mechanisms act to determine instantaneous transpiration rate, are...

Estimating Potential Evapotranspiration
Simple computational procedure whereby average daily potential evapotranspiration is represented as proportional to product of day-time hours squared and to saturated water vapor concentration...

Hydrology Handbook
Hydrology Handbook presents extensive information about the hydrologic cycle and engineering responses to it. The handbook is presented as...
