Calibration Accuracy for Constant Temperature Thermal Anemometer
Publisher: American Society of Civil Engineers
Abstract: Thermal anemometry is widely used to measure fluid velocity and boundary shear stress. Sensor calibration is required and results in a nonlinear equation with anemometer voltage as a function of fluid velocity or shear ...
Furrow Advance Using Simple Routing Models
Publisher: American Society of Civil Engineers
Abstract: Two simple models are developed to predict the advance rate of flow in furrows. The first model is developed using a modified version of Muskingum flood‐routing techniques. The second model is developed by assuming that ...
Methodology to Evaluate Performance of Sediment Control Log Filter Media
Publisher: ASCE
Abstract: Stormwater management is necessary to protect surface waters from pollutants, and significant amounts of time and money are being expended to purchase and install sediment control logs for this purpose. Testing to compare ...
Calibration and Validation of an Empirical Dissolved Oxygen Model
Publisher: American Society of Civil Engineers
Abstract: A common difficulty in stream health assessments is the scarcity of real-time dissolved oxygen (DO) data. Discrete DO measurements, collected at times often imposed by sampling constraints, are difficult to use in assessments ...
Hydrology and Nitrogen Components of a Simple Rye Growth Model
Publisher: American Society of Civil Engineers
Abstract: Cover cropping practices are being researched to reduce artificial subsurface drainage nitrate-nitrogen (nitrate-N) losses from agricultural lands in the upper Mississippi watershed. A soil-plant-atmosphere simulation ...
