Water-A-Plenty, 1987 Upper Rio Grande Water Year
The paper discusses hydrographs of streamflow and storage of the Upper Rio Grande Basin facilities as well as reservoirs at or near maximum storage. A description of the joint 1987-88...
Calibration of Water-Velocity Meters
The U.S. Geological Survey, Department of the Interior, as part of its responsibility to appraise the quantity of water resources in the United States, maintains facilities for the calibration...
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)...
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...
Unit Hydrograph Relationships for Small Urban Texas Watersheds
Snyder's unit hydrograph methods are used in a HEC-1 multiple sub-area routing model where the sub-area sizes average one to two square miles in size. However, the Snyder's...
Hydrograph Timebase
Based on the study of a large number of hydrographs, a graphic solution is presented whereby the length of the hydrograph timebase can be directly read from the proposed graphic solution...
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...
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...
Evaluation of Diffusion Models for Flood Routing
A study has been conducted to define the range of conditions with respect to hydrographs and channels encountered by SCS engineers in flood plain/flood control projects and to test two...
Morphologic and Hydraulic Adjustments of Red River from Shreveport, LA to Fulton, AK, between 1886 and 1980
Morphometric data (channel width and depth and slope) from 4 hydrographic surveys of Red River (1886, 1938, 1968, 1980) from Shreveport to Fulton and specific-gage analyses for the gages...
Modeling Side-Weir Diversions for Flood Control
Side-channel weirs can be used for diversion to reduce flood peaks. This study has developed a means for incorporating the effects of side weirs in HEC-1 and HEC-2 calculations through...
Partial Area, Variable Source, Rainfall Runoff Model Utilizing Digital Mapping
A partial area, variable source hydrologic rainfall/runoff model, called MAPHYD, was developed utilizing digital maps, interactive computer graphics, and several infiltration mechanisms....
Debris-Flow Research and Engineering Practice
For debris-flow analysis to enter standard engineering practice, future research must extend existing models to deal with major complications that arise in field practice. This paper reviews...
An Analysis of Channel Stability of the Red River from Shreveport, Louisiana to Index, Arkansas
To analyze the stability of the Red River in the study reach (Shreveport, LA to Index, AR) two comprehensive hydrographic surveys were studied. The hydrographic surveys were compared to...
Floodplain Regulation Downstream of Barrett Dam, CA
Barrett Dam is owned and operated by the City of San Diego, California. The Dam was built in the early 1920's to be an additional source of water for the growing City with...
