Analysis of Progressive Development on Alluvial Fans
Flow on alluvial fans is considered to be somewhat unpredictable and complex, experiencing high velocities, avulsions, erosion, and deposition causing a dynamic topography with flooding...
Hydraulic Design for La Quinta Stormwater Project
An upstream detention basin was designed to trap debris and attenuate flows into Bear Creek Channel. The high velocity supercritical flow made a one side bank protection design for the...
Overview o New England Coastal Flood Study Methodology
This paper presents an overview of the development of methologies used to determine the probabilistic flood levels for New England coastal flood insurance studies. The Federal Insurance...
Hydraulic Study for the Construction of Artificial Islands in Peoria Lake, Illinois
Long-term sediment accumulation in the lake reduced the average depth of the lake from 8 feet in 1903 to 2.6 feet in 1985, which resulted in the deterioration of aquatic habitats and recreational...
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...
Model-Prototype Study of Overland Flow
Similarity of overland flow hydrographs was investigated. Similarity ratios based on Froude number modeling were tested by using: 1) computed hydrographs by kinematic wave equations, 2)...
The USDA Water Erosion Prediction Project
New generation water erosion prediction technology is being developed by the USDA Water Erosion Prediction Project (WEPP). The new technology is expected to replace the Universal Soil...
Water Quality Modeling Using a Small Watershed Model (SWAM)
The Small Watershed Model (SWAM) is a state-of-the-art model that simulates the movement of water, sediment, and chemicals through a small, mixed-land-use watershed. It was developed to...
Watershed Runoff Forecasting Technique
Based on historical records of up to 57 years, a computer model was developed to establish the precipitation - runoff relationship for four reservoir systems in the Northeast portion of...
Model Complexity Required to Maintain Hydrologic Response
An increasing number of practitioners are using distributed hydrologic models employing kinematic routing. Watersheds are typically represented by a set of overland flow plane and channel...
Comparison of Peak Discharges of Hydrologic Models
The objective of this paper is to evaluate the predictive capabilities of hydrologic models in estimating the magnitudes and frequencies of flood peaks by comparing them with the values...
Kissimmee River: Engineering Approaches for Restoration
The Kissimmee River, located in central Florida, was channelized for flood control during the 1960s. Movements by environmental interest groups have produced strong sentiment to restore...
Evaluation and Testing of Storm-Event Hydrologic Models
Hydrologic models considered for this evaluation include: Areal Nonpoint Source Watershed Environmental Response Simulation (ANSWERS); a kinematic erosion model (KINEROS); Watershed and...
The TENN-V Storm Hydrograph Simulation Model
TENN-V is a computerized, lumped, non-linear stormwater hydrograph simulation model for small unregulated watersheds. The applicability of TENN-V is best established in watersheds of less...
Sensitivity of CUHP-PC Computer Model
The Colorado Unit Hydrograph Procedure (CUHP) consists of effective rainfall reduction and hydrograph convolution processes. The primary assumption is an one-to-one response between rainfall...
Runoff Simulation, Homestake II Project
Wetlands issues raised in connection with the proposed Homestake II Project required an extremely detailed evaluation of basin hydrology. The Subalpine Water Balance Model (WATBAL) was...
Mathematical Modeling of Delta Deposits and Retrogressive Erosion in Reservoirs
A hybrid computer model which simulates mainly delta deposition and retrogressive erosion in reservoirs is described. Basic equations that govern the flow and bed changes used in the model...
Stochastic Streamflow Sequences for Reservoir Operation and Design
A stochastic streamflow model is adapted for risk methodology in the operation and design of reservoirs. The model is based upon the representation of the flood series as a Poisson counting...
Stage-Frequency Analysis of Closed-Basin Lakes
Devils Lake in North Dakota is used as a case study for the model development and application. The basis of the relationship developed in this study is the separation of the annual maximum...
