The BRANCH Model and the Segara Anakan Study
The Lower Citanduy Irrigation Project in Central Java, Indonesia drains through the estuary called Segara Anakan. Due to sediment accretion, the lagoon is filling. With erosion problems,...
Hydrologic Forecasting in the National Weather Service
A description of hydrologic forecasting procedures of the National Weather Service (NWS) is presented. Also included is a description of various hydrologic products produced by the NWS...
Potential Effects of Global Climatic Change on the Tennessee Valley Authority Reservoir System
Rising concentrations of carbon dioxide (CO2) and other 'greenhouse' gases are likely to increase global temperatures and...
Rainfall Intensity-Duration Equations
A method for rapidly developing a rainfall intensity-duration equation for durations less than one hour and recurrence intervals between 2 and 100 years for any location in the conterminous...
Hydroturbine Efficiency and Cavitation Monitoring
The paper describes a microcomputer-based system for monitoring hydroturbine performance and cavitation level. Remote access to the monitoring system provides convenient, rapid, and accurate...
Bay/Delta Hydraulic Model?Thirty Years of Service
The San Francisco Bay and Delta is an extremely complex estuarine system. During the past thirty years, the San Francisco Bay/Delta Hydraulic Model has proven to be a valuable scientific...
Three-Dimensional Modeling of a Stratified Estuary
Development around Choctawhatchee Bay, and reduced productivity, loss of seagrass beds, and higher salinities, prompted the Northwest Florida Water Management District to conduct an investigation...
Harbor Restoration Through Improved Circulation
After several episodes of massive fish kills in Old Pass Lagoon on the Florida Gulf Coast, an investigation was undertaken to identify the problems and propose cost-effective solutions....
Approach for 3-D, Time-Varying Hydrodynamic/Water Quality Model of Chesapeake Bay
The U.S. Environmental Protection Agency (USEPA) has identified major contributing factors to the Bay's decline as inputs of nutrients and toxicants from point and nonpoint...
Development and Application of the Chesapeake Bay Eutrophication Model
The paper discusses the formulation of a steady-state coupled hydrodynamic/water quality model of Chesapeake Bay. The intent of this model was to provide insight into the processes and...
Entropy as a Probability Concept in Energy-Gradient Distribution
The concept of entropy based on probability theory instead of thermodynamic principle has been applied to study the distribution of energy gradient along alluvial rivers. The formulas...
Longitudinal Dispersion in Rivers: A Dead Zone Model Solution
The longitudinal dispersion of tracer material in rivers is often analyzed based on the one-dimensional convective diffusion equation developed by G.I. Taylor. However, the persistent...
Hydrologiic Risk Analysis for Small Dams in Missouri
A methodology is presented for calculating the risk cost for a dam based on probabilities for rainfall depth, antecedent moisture condition, rainfall time distribution, initial reservoir...
Hydrologic Safety of Earth Dams
Hydrologic and hydraulic analyses are presented pertaining to the safety evaluation of an earth dam located downstream of another smaller earth dam. The upper dam is assumed to breach...
Design of Riprapped Scour Holes for Flip Bucket and Overfall Spillways
Presented in this paper is a simple method of predicting pre-excavated scour depths and geometry for riprapped basins below flip bucket spillways. The input data needed for establishing...
Task Committee Report on Reliability Analysis of Water Distribution Systems
The results of the ASCE Hydraulics Division Task Committee on Reliability Analysis of Water Distribution Systems are summarized in a very comprehensive report entitled Reliability Analysis...
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....
Density Currents and Their Application in Hydraulic Engineering: Task Committee Progress Report
The Task Committee on Density Currents and Their Applications in Hydraulic Engineering operates under the Technical Committee on Hydrologic Transport and Dispersion. The Task Committee...
A Shopper's Guide to Urban Stormwater Software, Revisited
Results of a survey of urban stormwater software were first discussed by the author in August, 1985. A trend toward widespread adoption of SCS procedures as a new standard in urban hydrology...
