Introduction to Salt Dilution Gauging for Streamflow Measurement Part 2: Constant-rate Injection
Introduction Stream gauging by salt injection is a technique that will work in many streams in which current-meter measurements are unreliable. This extension note builds upon a previous Streamline article (Moore 2004b) and describes field and computational procedures for stream gauging by constant-rate salt injection. The emphasis is on small streams (less than about 2 m in wetted width) under...
متن کاملIntroduction to Salt Dilution Gauging for Streamflow Measurement Part IV: The Mass Balance (or Dry Injection) Method
In part one of this series, Moore (2004a) introduced the general principles of stream gauging by salt dilution. In subsequent articles, Moore (2004b, 2005) described techniques of constant-rate injection and slug injection using salt in solution. This is the final article in the series and details the “mass balance method.” Originally described by Elder et al. (1990), the mass balance method di...
متن کاملUsing 15N Dilution Method to Correct for Microbial Contamination When Assessing in situ Protein Degradability of Fresh Ryegrass
This experiment was done to investigate microbial contamination and in situ disappearance rates of dry matter (DM), N and 15N of fresh labeled ryegrass. Perennial ryegrass (Lolium perenne) were labeled with 15N during growth in a glasshouse, harvested at 4th leaves stage and were incubated up to 34 h in situ in the rumen of 3 individually housed sheep. The animals were fed 800 g/d chopped alfal...
متن کاملGauging Support for Innovative Farmland Preservation Techniques
This report describes the results of interviews and focus groups, gauging support for innovative farmland preservation techniques. Four techniques were selected for assessment from approximately 30 novel techniques identified in previous research: (1) Term conservation easements; (2) Land preservation tontines; (3) Rights of first refusal; and (4) Agricultural conservation pension with purchase...
