In-Situ Microocosms for Calibrating Dynamic Models
The calibration of dynamic water quality models for lakes and reservoirs requires significant quantities of data, experience, and judgement. In particular, the identification of an appropriate...

Modeling Urban Runoff Quality: State-of-the-Art
Procedures used in urban runoff quality modeling are reviewed in the context of common objectives of urban runoff quality analysis. The need for calibration/verification data is emphasized...

Leak Detection Is Just a Piece of the Pie
This paper emphasizes that leak detection is part of the proper management techniques that must be used to control unaccounted-for water. In order to effectively understand the pieces...

Water System Model Brought Improvements in System Performance
Analysis of the hydraulic conditions of a multi-pressure zone water system serving portions of two counties in a mountainous region of Southwest Virginia was performed using computerized...

Determining the In-Place Density of Soils Using the Sleeve Method
The sleeve method of determining the in-place density was developed by Bureau of Reclamation field personnel for cohesionless, fine, gravel soils used for pipe bedding when other methods...

Open Channel Flowrate Measurement Using Multipath Acoustic Flowmeters
Recent acoustic flowmeter developments have improved the applicability and accuracy of the multipath acoustic measurement technique. Accuracy, hardware cost and calibration cost can be...

Radar for Flood Forecasting-Reservoir Operation
The A&M Watershed Model will soon be capable of improved weather radar supported real-time flood forecasting and reservoir operations. Improvement in the scheme for inputting radar...

Design and Calibration of a 200-Foot Model Irrigation Border with a Computer Controlled Infiltrating Bed
A physical model of an irrigation border was constructed using a 200 ft long by 2. 5 ft wide tilting flume with a 3. 5 inch deep infiltrating gravel bed. The border was partitioned into...

Principles of Probabilistic Characterizations of Soil Properties
Sources of uncertainties affecting characterization of soil properties in a homogeneous soil layer include inherent spatial variability, systematic test bias, random test errors, calibration...
