Modelling the Effects of Wind on Pavement Runoff
Phase I of this study, the primary focus of this paper, consists of the development of a mathematical model to predict runoff depths from a pavement under uniform wind conditions. The...
An Approach for Modeling the Upper Chesapeake Bay
To resolve the bay geometry with a minimum number of grid points, boundary-fitted coordinates are employed. A major question is how to prescribe tidal boundary conditions at the Bay Bridge...
Hydrologic Forecasting in the National Weather Service
A description of hydrologic forecasting procedures of the National Weather Service (NWS) is presented. Also included is a description of various hydrologic products produced by the NWS...
Weathering Steel: Industry's Stepchild
Improper location and poor detailing are two reasons why some weathering steel bridges are not living up to their early promise. That was the consensus reached during a July 1988 forum...
Section Five—Construction Materials and Field Placement
Management of Computer Systems
Implementing a State PMS
Arizona State Pavement Management System (PMS) is described in this paper. Experience shows that many factors must be considered in deciding how to maintain a particular mile of the road...
Design of Drilled Piers in the Atlantic Piedmont
The philosophy and methods of drilled pier foundation design in the Atlantic Piedmont are described. Consideration is also given to the unique characteristics of decomposed metamorphic...
Computation of Supercritical Flow in Open Channels
The use of two explicit, shock-capturing, finite-difference schemes, Lax and MacCormack, for the solution of two-dimensional shallow-water equations in steady, supercritical flow is investigated....
Modeling the Effect of Weirs on Reservoir Releases
A computer model was developed to examine the influence of weirs on the rise of water levels and increases in velocities from reservoir releases. The model allows for investigation of...
Crop Production Models in Water Management
A weather generating model called WMAKER is introduced. The model generates daily climatic data based on the mean monthly values of temperature, precipitation, number of rainy days and...
Daily Diversion Forecasting for a Large Irrigation Project
A procedure has been developed and tested to forecast demand-type large irrigation diversions on a daily basis. The model is based on hydrologic concepts as well as irrigation scheduling...
Weather Modification Regulation for the Twenty-First Century
Those areas in which weather modification law is being altered to fit the twenty-first century are: 1. De-regulation. Regulation of weather modification through mandating professional...
Crop Yield Models Adapted to Irrigation Scheduling Programs
A crop yield model (CRPSM) was adapted to match the data obtained with typical irrigation scheduling programs. Daily soil water content was calculated from weather data, crop growth stage...
Spatial Attenuation of Major Pennsylvania Storms
To utilize point estimates for more expansive areas, reduction factors are necessary to account for the attenuation of storm magnitude with increasing area. The spatial attenuation of...
The Estimation of Rainfall for Flood Forecasting Using Radar and Rain Gage Data
The use of radar-rainfall data in combination with rain gage measurements may improve rainfall estimates over those based on either form of measurement alone. A set of rainfall analysis...
Denver Area Real Time System
This paper presents a discussion of the development of the Denver Area Real Time System which will be used to regulate the Denver reservoir system on a real-time basis. Its main components...
Modified CIMIS Irrigation Scheduling Program
CIMIS, California Irrigation Management Information System, is a program that collects weather data around the state to assist irrigators in planning and scheduling their irrigations....
Field Experiments for Wind Pressures
A project is underway at Texas Tech University to acquire wind and building surface pressure data in the field. Objectives of the project are to obtain a reliable data base for external...
Costs of Truck Related Highway Damage to Alaska
The cost of pavement damage to the State of Alaska for truck traffic continues to be a very controversial topic. There is no simple answer since this cost is dependent upon pavement strength,...
