Hydrologic Design Methodologies for Small-Scale Hydro at Ungauged Sites
IMP is a microcomputer package for evaluating small-scale hydroelectric power sites in British Columbia. With IMP it should be possible for an experienced hydroelectric engineer to make...
Using Fall Streamflows as Predictors of Spring Runoff at the Dalles, Oregon
The Northwest hydropower system is characterized by a drawdown season when normally full reservoirs are drafted to meet firm obligated loads, and a refill season in which the reservoirs...
Rainflow Cycles in Nonstationary Gaussian Processes
This paper develops a methodology for calculating the probability distribution for rainflow cycles in a nonstationary Gaussian process. The up- and downcrossing rates are estimated for...
A Front End Expert System for the Calibration of SWMM Runoff Block
An expert system is discussed which acts as a front end to the Storm Water Management Model (SWMM) for the purpose of preparation of data input and parameter selection. The structure of...
Comparison of Two Methods for Modeling Urban Runoff
The techniques currently available for modeling urban runoff can generally be grouped into discrete and lumped system approaches. The storm water management model (SWMM) provides procedures...
Optimal Use and Economic Value of Seasonal Runoff Forecasts
Each year the National Weather Service and the Soil Conservation Service issue a monthly sequence of five (or six) categorical forecasts of the seasonal snowmelt runoff volume for 760...
Underground Storage in Urban Stormwater Management
The use of underground pipe detention basins is discussed. These basins mitigate the frequency of localized flooding and sewer surcharging by effectively increasing the flow capacity of...
Field Testing of Selected Urban BMP's
This paper presents the results of field sampling of two urban BMP's (Best Management Practice), namely, a wet detention pond and a level spreader/vegetative buffer strip...
Reported Results from 600 Cloud Seeding Projects
The authors conclude that cloud seeding is an effective way of increasing precipitation when applied to the appropriate clouds and climate. Reported results from research projects show...
The Effect of Seeding on Convective Cells in West Texas
The effect on convective cells of randomized seeding for dynamic effects in the Southwest Cooperative Program is addressed. Analysis of three-dimensional, volume-scan, radar data using...
Computer Spreadsheet Applications to Small Site Drainage Engineering
The computer spreadsheet provides the drainage engineer with a simple, efficient, and adaptable tool for modeling drainage engineering problems. Engineering applications include runoff...
Diagnostic Strategies of an Expert System for Simulating Snowmelt Runoff
An expert system, EXSRM, is being developed for an existing and well tested snowmelt runoff model. The expert system assists an unfamiliar user in setting up the model to run and then...
Investigation of Runoff from a Subsurface Drained Field
This paper examines the relationship among rainfall, water table level and runoff hydrographs for subsurface-drained farmlands. It was found that peak flows were greatly influenced by...
The North Dakota Atmospheric Resource Program
For over a third of a century regions of North Dakota have conducted cloud seeding operations aimed at hail damage mitigation or rainfall enhancement. Cloud modification has become an...
Instrumentation for a Dry-Pond Detention Study
A 12.3-acre, fully urbanized, residential land-use catchment was instrumented by the U. S. Geological Survey in Topeka, Kansas. Hydraulic instrumentation for flow measurement includes...
Effects of Basin-Wide On-Site Stormwater Detention
The effect of basin-wide on-site detention of storm water runoff from developed areas is investigated to determine its effectiveness in reducing peak discharges in downstream portions...
Design and Evaluation of Storm Water Detention Facilities Using a Design Storm and Probable Maximum Storm
When designing a storm water detention facility, both a design storm (DS) and a probable maximum storm (PMS) should be considered. The DS is used to design the facility. The PMS is used...
Runoff Probability Distribution Characteristics
The probabilistic relations of an elemental rainfall - runoff process are analyzed. The elemental process is defined as runoff from a uniformly sloping impervious plane due to uniform...
Kinematics and Dynamics of Overland Flow
C. Y. Guo combined the kinematic wave approximation with Horton's infiltration formula to analytically solve the propagation of a two-dimensional overland flow on a previous...
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...
