The NOAA Hydrometeorology Testbed (HMT) program has deployed soil moisture observing networks in the watersheds of the Russian River and the North Fork (NF) of the American River in northern California, and the San Pedro River in southeastern Arizona. These networks were designed to serve the combined needs of the hydrological, meteorological, agricultural, and climatological communities for ob...

Slope reinforcement and the use of structural pile elements can be an effective slope remediation alternative when conventional remediation practices (e.g., improved drainage) fail to consider the causal factors leading to slope instability (e.g., strength loss due to weathering). An experimental research program was aimed at developing a rapid, cost-effective, and simple remediation system tha...

One of the critical factors for successfully conducting contamination characterization, removal, and remedial operations at hazardous waste sites is rapid and appropriate response to analyze samples in a timely fashion. Turnaround time associated with off-site analysis is often too slow to support efficient utilization of the data. Field portable X-ray fluorescence (FPXRF) techniques provide vi...

The Cerrado is the second largest biome in the country by area, located mainly in the central highlands of Brazil. Few details about the effect of managements in Cerrado soils that characterize the specific function of this soil biota in sustainable development of their fertility. Even with the lack of information on species of soil fungi in the Cerrado, there are few studies aimed to contribut...

The Soil-Water Characteristic Curve (SWCC) is an important soil function relating the water content of a soil to soil suction. Many unsaturated soil properties (or soil property functions) can be related to the water content versus suction relationship of a soil. Hydraulic conductivity, shear strength, chemical diffusivity, water storage, unfrozen volumetric water content, specific heat, and th...

The magnitude and extent of soil erosion in the Pacific Northwest region of the US still makes chilling reading. In a conventional farming approach in land mostly planted to winter wheat, there can be a loss of 12 bushels of topsoil, mostly from water erosion, for each bushel of wheat produced, with on-site losses of up to 1/8 in. of this highly fertile topsoil. Off-site outcomes were equally d...

A mathematical model, numerical algorithm and program code for simulation and long-term forecasting of changes in permafrost as a result of operation of a multiple well pad of northern oil and gas field are presented. In the model the most significant climatic and physical factors are taken into account such as solar radiation, determined by specific geographical location, heterogeneous structu...
