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....

Derivation of a Stability Principle from the Shields Criterion
The widely used specific energy equation, which defines the subcritical and supercritical states of the open channel flow, is a direct result of the integration of the Froude number corresponding...

Self-Accelerated Turbidity Current Prediction Based Upon Dynamic Turbulence Models
The structure of a self-accelerated turbidity current appears to be significantly better predicted by a dynamic Reynolds stress turbulence model than by one- and two- equation models....

Modeling Sediment Transport in Rectangular Ducts with a Two-Equation Model of Turbulence
The paper deals with the application of a two-equation model of turbulence to the calculation of flows in rectangular ducts. A non-linear relationship is used to link the Reynolds stresses...

Mathematical Models for Turbulent Shear Stress in Sediment-Laden Flows
Turbulent shear stress in sediment-laden flows has been examined by several investigators including H.A. Einstein and N. Chien A. Zagustin and J.C. Willis. Three derivations resulted in...

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...

Towards a Distinct Treatment of Incipient Motion for Bed Forms of Low Regime
The principle methods for estimating the incipient particle motion on developed bed forms in the lower regime are compared with each other. Usually only a part of the total wall shear...
