The Summer of 1993 Floods Lower Missouri River
Throughout the State of Missouri from November 1992 through July 1993, precipitation set new records, in some cases ranging as high as 200 - 400 percent of normal rain fall. Missouri precipitation...

Historical Rainfall-Runoff Analysis Using the Antecedent Precipitation Index
A long term simulation of rainfall-runoff can be used when analyzing the potential for economic benefits or flood damages to result from changes in the watershed, for developing discharge-frequency...

Minimizing the Probable Maximum Flood
A newly-developed probable maximum precipitation (PMP) estimate for Wisconsin and Michigan reduced precipitation depths by 20%. Should a given area's probable maximum flood...

A Derived Flood Frequency Distribution for Ungaged Catchments
Flood frequency distribution for ungaged catchments are described in the article. The various parameters that effect the flood frequency distribution are describes. Influence of the climate...

Selected Precipitation Characteristics in Antelope Valley, Mojave Desert, CA
An urban hydrology study currently in progress in Antelope Valley, California, includes the collection and analyses of precipitation and runoff data. Storms in Antelope Valley are most...

Storm Precipitation in Southwest British Columbia
The storm precipitation in a mountainous watershed in the southwestern British Columbia has been studied. Analysis of the spatial distribution of the storm features showed that the precipitation...

Temporal Variation of Precipitation Trend at Seoul, Korea, 1771-1991
This paper describes temporal variation of annual precipitation trend from 1771 to 1991 at Seoul, Korea. Analysis of the series shows no distinct trend over years. A linear trend would...

Effects of Climate Change on Drought Risks in the Apalachicola, Chattahoochee, and Flint River Basin
Possible effects of climate change on the Apalachicola-Chattahoochee-Flint (ACF) River basin is simulated with a computer model. Model inputs are monthly temperature and precipitation...

Combining Orographic Precipitation and Runoff Models for Improving Reservoir Operations
This paper reports on a study being conducted by the Bureau of Reclamation whose end objectives are improved quantitative precipitation forecast (QPF) for use in hydrologic runoff models...

Precipitation Data in the Mountains of the Western United States: Do We Have What We Need?
Data collected by the National Weather Service and the Soil Conservation Service in the western United States are the primary sources of precipitation information for engineering and hydrologic...

Mountainous Precipitation Estimation Using Multivariate Statistical Analysis and Geographic Information Systems
Using rotated principal component analysis (PCA), unique, orthogonal spatial patterns of daily and monthly precipitation on a well-instrumented, mountainous watershed in Idaho (USA) were...

Development of an Isohyetal Analysis for Oregon Using the Prism Model
PRISM (Precipitation-elevation Regressions on Independent Slopes Model) is an analytical model that uses point data and a digital elevation model (DEM) to generate gridded estimates of...

Convective Model Applications: Mountainous Terrain
Evaluation of precipitation in mountainous terrain has posed a vexing problem to many water-resources investigations due to the sparse and spotty network of reporting stations and gages....

PMF Estimation for a Sparsely Gaged Watershed
This paper describes a procedure used to determine the design-basis and probable maximum flood (DBF and PMF) for Jiguey Dam located in the Dominican Republic. This dam is situated upstream...

Incorporating GIS Technology in Standard Flood Hydrology Applications
The potential for application of Geographic Information Systems (GIS) to hydrologic analyses has received increasing attention in recent years. Published literature on hydrologic applications...

A Probabilistic Approach to Estimate Design Parameters for Flood Control Projects
The purpose of this paper is to provide engineering consultants with an improved method to estimate design parameters for various return periods in rural areas. The proposed method combines...

Estimating Floodplain Limits for Complicated Hydrologic and Hydraulic Conditions
A new approach for estimating floodplain limits is shown. A hydraulic model with flood routing capabilities is coupled with a hydrologic model to compute river stages. Simulations are...

A New Look at the Statistical Estimation of PMP
The statistical base of Hershfield's Kmvalue Method and its application for estimating Probable Maximum Precipitation (PMP) were reviewed. The mathematical...

Mean Areal Precipitation Estimation Using Radar
The accuracy of mean areal total storm precipitation (MAP) over small urban basins (30-100 km2) in the Denver, CO metro region was examined using...

WSR-88D Precipitation Processing and Its Use in National Weather Service Hydrologic Forecasting
The National Weather Service (NWS), along with the Department of Defense and Transportation, have begun deployment of a new national network of weather radars referred to as the WSR-88D....
