Streamflow Forecasting for the Bradley Lake Project
The National Weather Service (NWS) uses a suite of software called NWS River Forecast System (NWSRFS) for operational river stage and streamflow forecasting. NWSRFS is a modular system...

A Method for Conducting Real Time Flood Forecast
In this paper, first, it explains about the real time flood forecast which must be conducted at rivers in Japan. Next, as a means to an end, it is proposing the utilization of runoff computation...

River Characteristics of the Blue Nile Watershed
A common difficulty in modeling hydrological systems is the lack of available field data to assess the model parameters. In some cases, it is physically very difficult and expensive to...

Streamflow Depletions and Water Transfers in Idaho
In the state of Idaho, streamflow depletions are quantified utilizing parameters of rate of flow, total volume diverted, and volume consumptively used. This paper summarizes the engineering...

Streamflow Depletions for Water Transfers in Utah
All inter- or intra-state transfers of Utah water rights must be accomplished by application and receive the approval of the Utah State Engineer. This paper summarizes the engineering...

Streamflow Depletions Considered in Water Transfers
In the State of Colorado, streamflow depletions are defined as that amount of water diverted to beneficial use minus return flows to the stream system. This paper summarizes the engineering...

Streamflow Depletions Resulting from Ground Water Transfers
An application to move the point of diversion of a quasi-municipal ground water right from about 4.8 km to a second well about 0.3 km from a river channel was made in the Reno/Sparks,...

Sediment Budgets in Gravel Bed Streams
A sediment budget/mass balance technique is presented for use in assessment of sediment transport by river reach in gravel bed streams. Selection of appropriate gravel bed transport equations,...

Water Surface Profile Computations?How Many Sections do I Need?
One-dimensional streamflow models, including standard-step models, require a sufficient number of cross sections to satisfy two needs. First, a sufficient number of cross sections must...

The Flushing Flow Problem on the Trinity River, CA
Flushing flows are high flow releases designed to remove fine sediment accumulated in river gravels downstream of reservoirs. These releases must be designed to maximize transport of sand-sized...

Variation of Froude Number with Discharge for Large-Gradient Streams
Under chemical-control conditions, the Froude number (f) for a cross-section can be approximated as a function of the ratio R^{2/ 3}/d^...

A Numerical Model for Learning Concepts of Streamflow Simulation
Numerical models are useful for demonstrating principles of open-channel flow. Such models can allow experimentation with cause-and-effect relations, testing concepts of physics and numerical...

Protected Streamflow and Water Uses
The development of protected-streamflow standards is essential for the most desirable and equitable use of stream waters for aquatic habitats, municipal and industrial water supply, and...

Estimating Bridge Scour in New York from Historical U.S. Geological Survey Streamflow Measurements
Historical streamflow measurements by the U.S. Geological Survey an bridge-inspection reports by the New York State Department of Transportation are being used to estimate scour at 31...

River Engineering Flows and Some Related Structures (State of the Art)
The first part of the paper deals with a simplified overall review of water flows. Laminar versus turbulent, visualization of flow with unsteady 3-D manner and some typical hydraulic structures...

The Seattle Forecast Model: A Tool for Water Resources Management in the Seattle Area
The Seattle Forecast Model, SEAFM, developed by Hydrocomp Inc. for the Seattle Water Department, is an interactive, graphic system for streamflow forecasting and reservoir analysis of...

Maximum and Minimum Storage Trajectories That Meet Specific Risk Levels
One of Hydro-Quebec concerns is to operate its installations so as to satisfy the operating constraints. This paper describes a mathematical tool that enables the utility company to state...

7-Day 10-Yr Low Flow Relationships for Ungauged Sites in Central Italy
The principal objective of the present study was to establish relationships between some easily measurable basin characteristics and seven-day ten-year Low Flow Index, Q_7,10....

Streamflow Forecasting Using Trainable Neural Networks
In this investigation the practicality of applying a backpropagation neural network to modeling watershed response characteristics is examined. Two separate tests were performed. One test...

Probability and Climatology of Droughts in the Western United States
The incidence of drought in the western United States is caused primarily by large-scale anomalies in the circulation of atmospheric, midlatitudinal, transport and the occurrence of the...
