# Some Factors Influencing Required Reservoir Storage

*The impact of streamflow variability and correlation and demand patterns on the required capacity of a water supply reservoir were studied. Inflow traces were generated by simple Markov...*

In-Plane Bending and Buckling of Arches

*The state of knowledge of the in-plane bending and buckling of arches is summarized herein. There is a remarkable correlation between the critical thrusts for arches and columns. The buckling...*

Problems Associated with Planning BOD Experiments

*Possible inadequacies of commonly used long-term BOD experimental strategies are studied using actual BOD data and the first-order reaction model as a vehicle of analysis. The relation...*

Run-Up Distributions of Waves Breaking on Slopes

*Run-up of irregular waves which break on a slope is calculated by assuming that on the average the run-up of each wave with a given height and period equals the run-up of a periodic wave...*

Estimation of Design Freezing Indices

*A method for arriving at a rational estimate of the design freezing index for any place on the Canadian Prairies is described. A correlation between mean annual temperature, mean freezing...*

Dynamics of Correlated Random Pulse Trains

*Based upon the concept of infinite impulse trains, the paper introduces a physically realizable stochastic model defined as an impulse process. This model allows the random amplitudes...*

Impact of Spheres on Ice

*An oscilloscopic method for determining the coefficient of restitution,*e , by impact of spheres on ice was developed. Teflon, acrylic, nylon,...

Ultimate Torque of Rectangular Reinforced Concrete Beams

*Test results are presented herein concerning effectiveness of stirrups, distribution of longitudinal steel, and ultimate torque equation. The correlation with test results is also included....*

Physics of Desaturation in Porous Materials

*Previous investigations of the hydraulic properties of porous materials have been primarily empirical, i.e., correlations have been based upon experimental data. A physical description...*

Nitrogen Removal by Modified Activated Sludge Process

*A modified activated sludge process called contact-stabilization-denitrification makes it possible to eliminate 80% to 90% of the incoming total nitrogen in addition to the usual BOD removal....*

Hydrograph Synthesis by Digital Computer

*This study consists of hydrograph synthesis based on an investigation of runoff from small drainage basins in Texas. A technique for determination of the temporal distribution of infiltration...*

Space Correlations in Round Turbulent Jet

*Turbulence measurements were conducted in the mixing region of a turbulent round jet having a 0.2 ft diam and an efflux velocity ranging from 35 to 50 fps. All three components of the...*

Dispersion of Floating Particles in Uniform Channel Flow

*An investigation is given of the dispersion of small particles floating on the surface of an open channel with uniform flow and wide rectangular cross section. The dispersion was exclusively...*

Unit Graphs for Nonuniform Rainfall Distribution

*Correlation between Snyder's basin constants*Ct and 640 Cp and basin physical characteristics...

Regional Drought Frequency Analysis

*Analysis of severity and duration of droughts in central United States and Massachusetts is compared with available drought data from California, the Clearwater River, Illinois, the Soviet...*

Load Transfer for Axially Loaded Piles in Clay

*An analytical method for developing a theoretical load-settlement curve for axially loaded piles in clay is presented. The method is based on the correlation of the ratio of load transfer...*

In Situ Measurement of Solids in Final Clarifiers

*An apparatus was assembled and a method was developed for the in situ measurement of solids concentration gradients occurring in final clarifiers of an activated sludge process. Tests...*

Spurious Correlation in Hydraulics and Hydrology

*Spurious correlation is the correlation built into ratios, products, or other functions of two sets of random variables when the two sets have some elements in common. In hydraulic and...*

Traffic Accident Study On Milwaukee Expressway

*Correlations between traffic accidents and geometric design features of freeways are presented. On through lanes, visibility relationships with geometric features along the through lanes...*

Evaluation of Hydraulic Efficiency of Sedimentation Basins

*Detention time distribution curves of a pilot sedimentation basin were analyzed by the conventional method using central tendency values of the flow curve and by a new method in which...*
