Brief Description of Castor Software for Management of Reservoir Systems
The CASTOR group, started in 1984 at Ecole Polytechnique de Montreal (Canada), is a major software development project for an integrated CAD system related to hydro projects. Based on...
PROFS Role in Modernization of the National Weather Service
This paper describes the overall modernization procedure and the computing infrastructure that will support hydrologic operations in a prototype workstation that will be available in National...
Innovative Uses of Rainfall Prediction in Urban Flash Flood Forecasting
Operational prediction of excessive convective rainfall and the ensuing urban flooding has been an integral part of the Urban Drainage and Flood Control District's (UDFCD)...
WATFLOOD: A Real-Time, Microcomputer-Based Data Management and Flood Forecast System
WATFLOOD is a menu-driven micro-computer based flood forecasting system incorporating data management programs to enable real-time use of weather radar for flood forecasting. The main...
Geographic Information Systems for Hydrologic Modeling
Geographic information system techniques provide flexible and powerful capabilities for computer processing of spatial data sets integral to flash flood forecasting. Video digitizing or...
A Report on 18 Warning Systems in America
Of all weather related disasters in the United States, floods are the primary cause of death, and most flood related deaths result from flash floods. One of the major changes in flash...
Effecting Timely Responses to Urban Flash Floods
Problem identification and decision aid development are important first steps in putting together an effective flood warning plan. Until adequate data exists to allow refinement of runoff...
The Los Vaqueros Model: A Microcomputer-Based Reservoir Planning System
This paper describes the development and application of a set of microcomputer models for the evaluation of a complex water resources project. The Los Vaqueros Model includes components...
The Formation of Meandering and Braided Channels
Flow in alluvial channels implies flow past boundaries that form and deform under the action of the flow. Interaction between the flow and the mobile boundaries produces channel patterns...
Methods and Applications of Numerical Hydrology on a Drainage Basin
A model is presented here (MOMID) to study, having considered a morphological base of the drainage basin, the unit hydrogram and the routing time along the basin itself....
Reliability of Bank Protection Works Subject to Erosion
Sediment movement and changes of bed levels in natural rivers are non-stationary processes. The design of protection works for structures against erosion should account for the time dependency...
Model Study of Side Slope Riprap
Laboratory experiments were conducted in 10-m long channels having 1.5 H : 1 V side slopes protected with a 20.7-mm diameter rock layer 1.5 diameters thick. Four models were tested. In...
Method to Predict Cropland Ephemeral Gully Erosion
The U.S. Soil Conservation Service (SCS) in cooperation with the Agricultural Research Service (ARS) has developed a microcomputer program to provide estimates of the average annual material...
An Overview of Computer Stream Sedimentation Models
This paper discuss some of the author's experience in computer modeling of stream sedimentation problems. Comparisons of twelve selected models developed and implemented in...
Areal Sampling Techniques
Three areal methods, commonly used for sampling the coarser surface layer of gravel-bed streams, are examined. An idealized sediment deposit, that consists of cubic particles and accounts...
Sediment Transport Modelling from Grain Size Data
Grain-size analysis can be useful in determining some of the hydrodynamic aspects of the evolution of a natural sand body. The suite statistics approach minimizes single-sample anomalies...
Prediction of Time Development of Local Scour
The prediction of the time development of local scour is commonly solved by means of model tests. A brief description of the time-scale and the relation between the time and the scour...
Suspended Sediment Regression Model on Mud Coasts
Two statistical models of the concentration of suspended sediment on mud coasts have been developed by using the stepwise regression method. The statistical analysis in this paper is based...
Limitations of Modeling High Concentration Streams
Following the 1980 eruption of Mount St. Helens, high sediment concentrations caused rapid deposition and increased flood hazards along the Cowlitz River. The Corps of Engineers developed...
On the Coexistence of Bedload and Suspended Transport for a Uniform Grainsize Material
A sensitivity analysis and an experimental verification have been made to assess the validity of the equations that describe the sediment transport in non-equilibrium conditions, when...
