Late Glacial to Modern Climate Near Yucca Mountain Nevada

The Use of Iron Salts to Control Dissolved Sulfide in Districts' Trunk Sewers
Headspace H2S removal via the precipitation of dissolved sulfide was investigated using iron chlorides. Full-scale experiments were conducted in...

Frequency of the 1993 Flood in the Upper Mississippi River Basin
The frequency of the 1993 flood in the upper Mississippi River Basin is characterized by applying Bulletin 17B and L-moment methods to 111 unregulated watersheds in the basin. The analysis...

Long Term Predictability of River Stages under ENSO Influence
The paper explores the bases for alternative approaches to river flow and hydrologic time series forecasting. The precipitation that forces river flow contains significant modes of variability...

Climatic Perspective on the 1993 Mississippi R. Flood
The 1993 summer flooding in the Upper Mississippi River Basin was the most devastating flood of modern times with damage estimates in the range of 15-20 billion dollars. The paper describes...

Historical Trends in Flood Discharges on the Upper Mississippi River
Long-term streamgage records in the Upper Mississippi River Basin were analyzed using a Kendall Tau-b analysis to determine trends in flooding and average flows. Over the 130 years of...

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...

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...

Threshold Precipitation Events and Groundwater Recharge
Data from two study sites on the Nevada Test Site, Nevada are used with precipitation data from other long-term precipitation gages to identify the frequency of precipitation events that...

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...

The National Drought Atlas

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...

Simulation of Daily Climatic Series for the Assessment of Climate Change Impacts on Water Resources
A new approach to the generation of climatic time series for studies of the impact of climate change on water resources is presented. The method adapts a current stochastic weather generator...

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...

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....

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...
