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...
Finite Element Modeling in Free-Surface Hydromechanics
A finite element semi-discrete approximation is applied to the conservation law form of the two-dimensional, depth-averaged free-surface Navier-Stokes equations governing incompressible...
Urban Drainage Calculation Limits for Small Areas
This paper discusses the selection and application of hydrologic techniques in the design of stormwater facilities, with particular emphasis on the selection of hydrologic procedure for...

U.S. Army Corps of Engineers Sedimentation Engineering Manual D. Reservoir Sedimentation
This paper discusses Chapter 5, Reservoir Sedimentation, of the U.S. Army Corps of Engineers' Engineering Manual (EM) on Sedimentation Engineering, EM 1110-2-4000. The chapter...
Stream Flow Model for a Coastal Stream in Egypt
The Coastal region north of Egypt contains many small streams known as Wadis which are considered the main water resources in that region. All the Wadis in the north coast of Egypt run...
Hydrodynamic Response of an Estuary to Storm Forcing
Previous work on the response/sensitivity of an estuarine hydrodynamic model to the choice of model parameters is extended to include a preliminary consideration of wind-generated waves....
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,...
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...
Fine Contaminated Sediment Erosion/Deposition in the Buffalo River, New York
This paper documents part of a project which sought to characterize sediment transport in the Buffalo River as a contribution toward planning for dredging or in-place containment of the...
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...
Unsteady Flow in a Navigation Channel
Based on the de St Venant equations, the Preissmann's implicit finite difference scheme, and the double sweep algorithm, a mathematical model for one-dimensional unsteady...
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...
Sediment Flushing Experiences at Cherry Creek Dam
An overview of the U.S. Army Corps of Engineers, Omaha District's experiences in sediment flushing operations at Cherry Creek Reservoir near Denver, Colorado is presented....
Application of Reservoir Sedimentation Data to Problems of Environmental Management
Application of sediment delivery ratios and sediment routing procedures to sediment measurements provide an alternative approach to the prediction of localized average annual erosion rates....
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...
Uncertainty and Value Analysis in the Selection of Dam Modification Alternative
Objectives and attributes were decided by the dam and watershed requirements, value judgments of decision makers, quantified trade-offs between different attribute values, and technical...
Hydraulic Effects on Swimming Fish in Fish Passage Structures
The implications of profile drag, weight, and buoyant forces on energy and power requirements of fish swimming through fish passage structures are considered. Where hydraulic grade lines...
Flow Through Fish Bypass Intakes
Hydraulic and computational fluid dynamic models were used to investigate the cause of the unequal intake flow distribution observed entering the three vertical intakes of the patented...
Groundwater Transport in a Heterogeneous Aquifer: Tracking a Complex Plume
