SpatioTemporal Stochastic Open-Dhannel Flow
The de Saint Venant equations are solved as stochastic partial differential equations whose parameters (hydraulic resistance, bed slope, cross-section geometiy, inflow hydrograph, seepage,...

Analysis of Bank Stabilization in Steep Complex Streams Using A Two-Dimensional Model
In cases where the channel is fairly uniform, and not divided, one-dimensional hydraulic models, such as HEC-2, generally give adequate results for scour evaluations and bank protection...

Simulating Evapotranspiration on Semi-Arid Rangelands
Detailed simulations of the surface energy balance using the Simultaneous Heat and Water (SHAW) model were compared with measurements collected at the Reynolds Creek Experimental Watershed...

The Impact of Numerical Precision on Optimal Groundwater Hydraulic Control
The numerical precision retained in the formulation of groundwater hydraulic control optimization problems can have significant impacts on the accuracy of the solution. Sources of imprecision...

Impact of Sedimentation Caused by Runoff
As water is pumped into a reservoir, sedimentation caused by runoff can be an important factor in the reservoir's storage capacity. This report discusses various studies conducted...

Application of the Newton Method in Valve Discharge Coefficient Relationships
This paper presents a methodology that utilizes the Newton Method to compute the dimensionless valve discharge coefficient Cd from a manufacturers valve discharge coefficient Cv. The implicit...

Game Model Approach to Multi-Purpose/Multi-Objective Water Resources Related Environmental Protection Project Planning and Management in Developing Nations: A Nigerian Example
The best has not been realised from water resources related environmental protection projects in Nigeria due to problems militating against such projects at the planning, management and...

Hazardous Soil Remediation: A Cooperative Effort between Industry and Government
E. I. du Pont de Nemours and Company's Antioch Works (Dupont) is on the San Joaquin River 30 miles east of San Francisco, California. For about 25 years, ending in 1981, Dupont...

Aquifer Transmissivity Computations Based on Data from Pump-and-Treat Facilities
Contamination from petroleum hydrocarbons spilled from USTs is a concern in urban areas that depend on shallow unconfined aquifers for their water supply. Studies on the transmissivity...

Reductive Pyrolysis for the Destruction of Chloromethane: A Reaction Pathway Model Based on Thermodynamic and Thermokinetic Considerations
Among various thermal technologies available for the destruction chlorinated hydrocarbons, incineration, catalytic hydrogenation, and pyrolysis are important. Pyrolysis employed under...

Design of Riparian Habitat Replacement in Active Floodplains
Conventional flood control engineering techniques and approaches that have been traditionally been applied are now challenged by the public and no longer readily available as floodplain...

Looking for Evidence of Climatic Change in Streamflow Time Series
The principle of stationarity of a streamflow time series has been very commonly assumed in the analysis of hydrologic time series. Some common types of non-stationarity in time series,...

Using HEC-RAS to Compute Scour at Bridges
HEC-RAS (River Analysis System) is an integrated system of software, designed for interactive use in a multi-tasking environment. The system is comprised of a graphical user interface...

Simulation of Interaction between Canal Regulation and Groundwater
l-D canal routing module has been developed to perform the operation of controlled structures for regulating flow in the canal network system and incorporated in the Three-Dimensional...

Simulation of Perilithic Algae as a Biofilm and Its Interaction with the Water Column
A one-dimensional bioflim model has been constructed consisting of a particulate phase of algae and inert material and diffusive transport of nutrients and oxygen. Also included is mass...

Protecting Drinking Water: Rapid Detection of Human Fecal Contamination, Injured, and Non-Culturable Pathogenic Microbes in Water Systems
The rapid, potentially-automatable extraction of filter retentates has allowed quantitative detection of the unique biomarker for human fecal contamination, coprostanol, and the signature...

A Comparative Study of the Transformed Methods for Solving Richards' Equation
The Richards' equation represents the movement of water in both saturated and unsaturated porous medium. The numerical solution to this equation is difficult because the algebraic...

Design and Construction of the Santa Ana River Wash Crossing of the Inland Feeder
The Inland Feeder Pipeline passes beneath the Santa Ana River in Southern California. The flood plain of the river provides the habitat for two endangered species and to avoid surface...

Direct Sizing of Small Stormwater Pump Stations
Pump stations are components of stormwater drainage systems that remove collected storm runoff from locations where drainage by gravity is not feasible. Usually pump stations will operate...

Scour around Exposed Pile Foundations
Laboratory experiments were conducted to measure local scour around exposed pile groups for a variety of conditions including different spacings, different skew angles, different patterns...
