Simulation of a Surface Water Allocation System
This paper outlines the water rights system in Texas and a newly developed computer simulation program for modeling this system. In addition, an overview of a river basin simulation using...
Tucson, Arizona's 110-Year Water Resources Plan
The desert community of Tucson, Arizona, has just completed a state-mandated 110-year water supply plan. The plan includes conjunctive use of local groundwater and surface water imported...
Stochastic Optimization of Conjunctive Use in Pakistan
This paper describes an optimization analysis of conjunctive use of ground and surface water that incorporates stochastic inflows and regional variations in groundwater quality and availability....
The Genesis of Surface Water for San Antonio
San Antonio is the ninth largest city in the United States and the only one of that group that relies exclusively on groundwater. The Applewhite Water Supply Project is the first surface...
Groundwater Contamination from an Unlined, Poorly Capped Landfill
This paper presents a case study of groundwater and surface water contamination from a major, unlined, and poorly capped municipal landfill located in Western Washington. The landfill...
Resistance Coefficient in a Tidal Channel
In applying a numerical hydrodynamic model to the tidal channel-lagoon complex around Great Sound, New Jersey, it became apparent that the model guidelines for the resistance coefficient...
Strides in Nondestructive Testing
Stress wave methods of nondestructive testing are increasingly used in civil engineering applications. Four case histories of the use of different types of stress wave testing are given....
Assessing Nonpoint Pollution Potential of Surface Waters Using a Geographic Information System
The use of Geographic Information Systems (GIS) to determine the susceptibility of surface waters to nonpoint pollution is described. The Geographic Resources Analysis Support System (GRASS)...
Utility of a GIS in Watershed Management?A Case Study
A geographic information system data base was established for a small watershed in Shelby County, Tennessee, for both surface and subsurface water attributes. The surface water portion...
Effects of Surface Drainage on Sediment Yield in Southern Delaware
Sediment surveys were conducted over a period of 16 years on two small reservoirs in the Nanticoke River basin, Delware in order to assess the effects of watershed drainage projects on...
Intergovernmental Agreements in Watershed Planning
Management of the surface water system not only rests with state and federal agencies, but more importantly, with local jurisdictions. Recognizing this, a cooperative effort was undertaken...
Infiltration or Roughness from Surface Irrigation Advance
Over the past several decades, a significant effort has gone into the development of mathematical models of water flow over the soil surface. Significant progress has been made in prediction...
Application of Neutron Soil Surface Water Monitoring for Plant Establishment
Soil surface water content measurements are tedious and time consuming, and to improve on such tasks, a neutron surface moisture probe was modified by using cadmium shielding. This prevented...
Effects of Surface Drainage on Sediment Yield in Southern Delaware
Sediment surveys were conducted over a period of 16 years on two small reservoirs in the Nanticoke River basin, Delaware in order to assess the effects of watershed drainage projects on...
California-Nevada Water Marketing Issues
Many California local agency interests tend to oppose, at least initially, transfers of water across the stateline to Nevada, and have been to some extent successful in creating provisions...
Piedmont-Fan Flood Hazard Analysis From Geomorphology and Surface Water Hydrology, Hudspeth County, Texas
A 2-mi2 (5.2 km2) site selected by the Texas Low-Level Radioactive Waste Disposal Authority was technically...
An Experimental Study of Oil Spreading in Ice Covered Waters
In this paper the experimental procedure and some preliminary observations from a new series of experiments on the mechanism of oil spreading under fragmented ice are presented. Laboratory...
A Mathematical Model for Transport and Mixing of Oil Slick in Rivers
A two-layer two-dimensional mathematical model for transport and mixing of oil in rivers is presented. In this model, oil in the river is considered to consist of a surface slick moving...
Numerical Computation of Free Surface Weir Flow Using Isoparametric Finite Elements
Numerical computation of flows with a free surface boundary involves three problems in one: the internal flow problem, location of the free surface and the actual flow rate. The development...
Grid-Induced Errors in Depth-Averaged Flow Fields
A computer code called CH2D (Curvilinear Hydrodynamics in Two Dimensions) for computing depth-averaged free-surface flow fields has been used to assess the impact of the rate of change...
