Optimal Risk-Based Design of Storm Sewer Networks
Optimal design of sewer network has conventionally been pursued within a deterministic framework. However, such design may be appropriate because of existence of uncertainties affecting...

Dynamic Behavior of Pit Slopes in Response to Blasting and Precipitation

Determining Streamflows from Geomorphic Parameters
To predict streamflow, hydrologists and geomorphologists have sought to relate streamflows to geomorphic parameters, and vice versa. Data continuity problems were addressed by statistical...

Some Procedures for Determining Extreme Precipitation Criteria

San Francisco Precipitation and Flow Measuring Network

Infiltration and Antecedent Precipitation
A simple, inexpensive, and expedient method is presented for determining the initial infiltration capacity (fo),...

Leachate Treatment by Coagulation and Precipitation
When sanitary landfills are constructed with provisions for collection and treatment of leachates, chemical treatment may be one of the treatment processes employed. The research described...

Houston Infiltration Abatement Program
The City of Houston, Texas, has embarked upon a program of infiltration abatement that provides for an orderly approach to the conception, development, and implementation of a plan to...

Electroprecipitation of Phosphate from Sewage
A study of phosphate removal from secondary sewage effluent was conducted using a two-step method of electroprecipitation followed by lanthanum chloride precipitation. In the first step,...

Inadvertent Weather and Precipitation Modification by Urbanization
Urban-industrial complexes produce measurable inadvertent modification of all weather conditions and specifically significant increases in the precipitation conditions of interest to hydrologists...

Precipitation Enhancement Program for Illinois
Study of possible solutions to such problems has shown that precipitation enhancement is one potential solution. The 5-yr planning and research program is composed of 10 studies to obtain...

Priority Problems for Modifying Cumulus Precipitation

Effectiveness of Precipitation in a Mountain Meadow

Potential of Precipitation Modification
The potential cost advantage of precipitation modification over other methods of increasing water resources is conditional upon the percentage precipitation increase over climatology in...

A Model to Predict Mean Annual Watershed Discharge
A method was developed for the estimation of long term discharge characteristics of small watersheds. It was shown that, besides the annual precipitation and the annual mean temperature,...

Where is Urban Hydrology Practice Today?
The evolution of urban street construction and its effects upon urban drainage is traced. Rational method development and inconsistencies in its application are summarized. The emphasis...

Stochastic Analysis of Periodic Hydrologic Process
The harmonization of a stochastic process allows the Fourier-Stieltje's integral to represent a nonstationary stochastic process of the periodically correlated type. Therefore,...

Runoff Grouping for Detection of Change in Runoff
The purpose of this study was the determination of suitable watersheds or combinations of watersheds for precipitation management programs in the upper Colorado River Basin in general...
