Modeling Field Moisture in Resilient Moduli Testing

Moisture Barrier Effects on Pavement Roughness

Simulation of Post-irrigation Moisture Changes for Surface Irrigation of Corn
An attempt has been made to refine prediction of irrigation efficiency obtained at the end of an irrigation by accounting for the losses that occur during redistribution. The water budget...

Methods for Determining Actual Evapotranspiration in Plots
The major methods used at INRA since 1965 for determining actual evapotranspiration (AET) in plots are reviewed in this paper. These procedures involve either direct determination (weighing...

Bulk Stomatal Resistance in Operational Estimates of Evapotranspiration
General relationships for estimating canopy or bulk stomatal resistance and aerodynamic resistances of grass and alfalfa reference crops for use in the Penman-J.L. Monteith equation are...

Hydrologiic Risk Analysis for Small Dams in Missouri
A methodology is presented for calculating the risk cost for a dam based on probabilities for rainfall depth, antecedent moisture condition, rainfall time distribution, initial reservoir...

Implementing a State PMS
Arizona State Pavement Management System (PMS) is described in this paper. Experience shows that many factors must be considered in deciding how to maintain a particular mile of the road...

Artificial Recharge Research at the University of Arizona
This paper summarizes pit- and well-recharge trials at Tucson, Arizona. The pit recharge trials examined management techniques and characterized flow patterns in the 80 ft thick vadose...

A Knowledge-Based Approach for End-Use Design Stresses in Wood

The Alaskan Arctic Coast: Wetland or Desert?
Deserts can be defined by low precipitation and lack of water. The Alaskan Arctic coast receives approximately 18 cm (7 in. ) of precipitation annually and for 8 months of the year there...

Hydrologic Design Criteria for Dams with Equal Reliability
Appropriateness of design criteria which require using the same Antecedent Moisture Condition (AMC) throughout Kansas for sizing dams and emergency spillways was examined. AMC values which...

CWSI and Stomatal Resistance of Cotton and Soybeans
A new instrument, Scheduler(TRADEMARK), has been developed to measure the onset and duration of plant water stress. This device consists of a sensor package (containing an infrared thermometer,...

Influence of Rock Moisture on the Longitudinal Wave Velocity

Large Mat Foundation Analysis on Expansive Soil
This paper describes a comparison of predicted and observed performance of mat foundations on stiff expansive soil. Foundation performance was predicted using a new computer program BOSEF...

Details for Durable Timber Structures

Irrigation Development in Alberta, Canada
Agricultural production in the southwestern part of the Canadian prairie provinces is limited by insufficient rainfall for optimum crop production. To overcome this moisture deficiency...

Lessons Learned From Examination of Membrane Roofs in Alaska
During 1984 and 1985 airborne infrared roof moisture surveys were conducted of membrane roofs at Army installations in Alaska. Many of these roofs were also visually inspected and cored...

Moisture Effects on Extruded Polystyrene Insulation
The amount of moisture within the insulation was determined by carefully weighing each sample and then measuring its volume. Two methods of measuring thermal conductivity were used. The...

Interrelating Infiltration Measurements
Field measurements of infiltration rates are frequently used to index environmental conditions, soil hydrology, and the potential for rainstorm response. However, the variety of methods...

Alaska Wetlands: An Opportunity for Protection
Alaska has retained the majority of wetlands as intact functioning ecosystems. These areas encompass 57% of the land area of the state or, about 223 million acres. Wetland types vary from...
