Navigation Lock Improvements
All commercial barge traffic on the Upper Mississippi River and Illinois Waterway must pass through a system of locks designed and built in the 1930s and 40s. Many of the locks on these...
Filling and Emptying System Model Study for the Innovative Lock Design
Funding constraints have generated innovative ideas regarding the hydraulic system of proposed navigation locks. Two fundamental questions addressed in the innovative lock design study...
Entrainment of Eggs and Larval Fish into Propeller Jets
Because larval fish have limited mobility and eggs have no mobility, both are susceptible to entrainment into the propeller jets of passing vessels. Entrainment subjects eggs and larvae,...

Development of a Hydrologic Model with Both Spatially Distributed and Physically Based Capabilities
A distributed hydrologic model is developed at The Pennsylvania State University for use with rasterized data bases. The purpose of the Terrestrial Hydrologic Model or THM is to investigate...
Runoff Computation Using Spatially Distributed Terrain Parameters
A spatially distributed unit hydrograph is developed based on linear system theory applied to subareas or cells within a watershed Each cell has a unique unit response function independent...
Modeling of Rattlesnake Creek Watershed Using Swat Model
Watershed scale models are widely used in design and operation of river basin projects and for guiding public decisions. This paper presents modeling details of Rattlesnake Creek watershed...
Restoration of Abandoned Meanders on the Middle Fork Forked Deer River, Tennessee
The Middle Fork Forked Deer River in western Tennessee historically had a sinuous course within a wide floodplain. In the early 1900's, local interests dug large straight...
Simulation of Catchment Response Using RC Network
This paper describes a simple physically-based distributed parameter hydrologic model of catchment response using a network of capacitors and resistors. The effect of topography is modeled...
SAMS: Software for Simulating Streamflow Series
This paper introduces SAMS, a computer software developed for the analysis, modeling, and generation of hydrologic time series such as annual and monthly streamfiows. It is written in...
Optimization Modeling of Complex Surface Water Collection Systems
The New York City (NYC) water supply system is currently being modeled using Linear Programming (LP) optimization techniques. A series of simulations were performed to investigate the...
Impacts of Climate Change in the Missouri River Basin
The Soil and Water Assessment Tool (SWAT) is being used as a base model to simulate the Missouri River basin for prediction of the impacts of climate change on water resources in the region....
Water Balance of the Niger Basin
A map-based method is used to construct a monthly water balance model of the 2.3 million km Niger River basin in West Africa. The watersheds and stream network within the basin are derived...
Preliminary Validation of the MAC3D Numerical Flow Model
MAC3D is a recently developed numerical model for three-dimensional incompressible flow. Model predictions are compared with physical test data for a curved open channel and a multi-level...
A Finite Element Analysis of Mach Reflection by Using the Boussinesq Equation
The numerical analysis of Mach reflection, which is the reflection of an obliquely incident solitary wave by a vertical wail, is presented in this paper. For the mathematical model in...
3D Flow Structures?From Laboratory to Field Applications
One laboratory experiment and one field application have been modeled. For each one different sources of errors in the model results could be detected. It may be concluded that the applicability...
