Automatic Downstream Water-Level Feedback Control of Branching Canal Networks: Theory
(American Society of Civil Engineers, 2006)Most of the research on the design of feedback controllers for irrigation canals has been concentrated on single, in-line canals with no branches. Because the branches in a network are hydraulically coupled with each other, ... -
Watershed and River Systems Management Program: Overview of Capabilities
(American Society of Civil Engineers, 2006)Beginning in January 1992, the Bureau of Reclamation (Reclamation) and the US Geological Survey (USGS) formulated plans for the Watershed and River Systems Management Program—a cooperative interagency effort to develop and ... -
Hydrologic Modeling Inventory: Cooperative Research Effort
(American Society of Civil Engineers, 2006)The hydrologic modeling inventory developed at the Bureau of Reclamation and posted at its website ⟨http://www.usbr.gov/pmts/rivers/hmi⟩ is described. The inventory comprises a large number of state-of-the-art watershed ... -
Automatic Downstream Water-Level Feedback Control of Branching Canal Networks: Simulation Results
(American Society of Civil Engineers, 2006)Previous research on canal automation has dealt with the control of single, in-line canals, while canal operators typically have to control an entire network of canals. Because the branches in a network are hydraulically ... -
Estimating Evaporation from Bare Soil Using Soil Moisture Data
(American Society of Civil Engineers, 2006)A method is presented that uses continuous soil moisture measurements and hourly reference evapotranspiration data to estimate a soil hydraulic factor -
Salt River Project Canal Automation Pilot Project: Simulation Tests
(American Society of Civil Engineers, 2006)The feasibility of automatically controlling water levels and deliveries on the Salt River Project (SRP) canal system through computer-based algorithms is being investigated. The proposed control system automates and ... -
Effect of Controlled Drainage and Vegetative Buffers on Drainage Water Quality from Wastewater Irrigated Fields
(American Society of Civil Engineers, 2006)Lagoon effluent is routinely applied to agricultural fields as fertilizer to utilize nutrients derived from animal manures. In humid regions, effluent is also applied to fields in order to manage the lagoon stage within ... -
Dimensionless Stage–Discharge Relationship in Radial Gates
(American Society of Civil Engineers, 2006)Dimensional analysis was used to obtain stage–discharge relationships under submerged and free flow conditions in radial gates to develop a management tool. Experimental data from a laboratory flume and the indicial method ... -
Performances of Hydraulics and Bedload Sediment Flushing in Rigid Channel Using Surge Flows
(American Society of Civil Engineers, 2006)This paper presents an investigation of the performance of the hydraulic and sediment removal of a flushing system in a detention basin. A hydraulic criterion for the design of the flushing system is proposed. An equation ... -
Flow Patterns and Energy Dissipation over Various Stepped Chutes
(American Society of Civil Engineers, 2006)To reduce the size of the dissipation basin, the stepped chute has been accepted to be the most powerful hydraulic structure to dissipate large flow energy downstream from steep hills. This paper presents the flow ... -
Stochastic Streamflow Simulation Using <i>SAMS-2003</i>
(American Society of Civil Engineers, 2006)is a specialized software that has been developed for analyzing, modeling, and generating synthetic samples of hydrologic and water resources time series such as monthly streamflows. The 2003 version of -
