the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

True integrated weed management

Using the simplest of definitions, integrated weed management has been described as “putting components [of weed control] together, not taking them apart.” Yet, weed science has stopped at the “field edge” in assembling the components into a truly integrated approach. What is keeping weed scientists from developing real integrated weed control regardless of space and time? The answer to this qu...

PEST MANAGEMENT: WEEDS Weed Management Needs in Arkansas Rice

Certified Crop Advisors of Arkansas and members of the Arkansas Crop Consultants Association were surveyed in fall 2006 through direct mail to assess current weed management practices and needs in rice from both a research and educational perspective. Consultants reported scouting 564,000 of the possible 1,400,000 acres (40%) of rice grown in Arkansas. Preemergence herbicides most often recomme...
