Watershed Simulation for Characterizing Droughts Under the Influence of Climate Change
The paper describes a model for simulating soil moisture deficit on a daily basis using historical rainfall and climatic data for the analysis of droughts. Distributed parameter hydrologic...
Comparison of Nested Models' Local-Scale Precipitation from a Three-Year Base Run and a Corresponding Doubled CO2 Run
Comparisons were made of nested model simulated precipitation from a 3-yr base run and the corresponding doubled-CO2 run for the Gunnison watershed...
Evaluating and Guiding Weather Modification Efforts with Advanced Three-Dimensional Numerical Models
Several recent developments have expanded our capabilities to understand and document precipitation processes. One of these developments is the recent advances in computer hardware and...
Models for Simulating Hydrology and Water Quality on Drained Soils
Design and operation of drainage and related water management systems should consider both agricultural production and environmental impacts. This is currently required in many locations...
Optimizing Irrigation Management for Pollution Control and Sustainable Crop Yield
We developed a simulation-optimization model which maximizes crop yield while maintaining target salt concentration in the root zone, and/or preventing salt from leaching to the groundwater....
Farmers' Incentives to Reduce Groundwater Nitrates
Nitrate leaching from irrigated crops is a productive input loss to the farmer and a possible source of environmental degradation. This study uses a simulation model to analyze incentives...
Furrow Irrigation Education
A furrow irrigation simulation computer model based on the volume-balance method is described. The model is used to develop information on furrow system performance that can be used in...
Development of a Hydrological Database for PROSIM?A Water Rights-Based Operational Simulation Model of the Provo River
The development of a hydrological database for a computer model of the hydrology, water rights, and operations of the Provo and Weber rivers is described. The model uses all pertinent...
Flow Simulation for Surface Irrigation Design
Experience shows that even the most sophisticated and accurate computer models of the surface-irrigation process will not be widely used by design agencies unless they manifest a certain...
Software Engineering for Irrigation and Environmental Applications
Interactive, user-oriented software has been developed to enhance irrigation design, management and planning. Environmental applications were the central focus of several individual components...
Streamflow Depletions Resulting from Ground Water Transfers
An application to move the point of diversion of a quasi-municipal ground water right from about 4.8 km to a second well about 0.3 km from a river channel was made in the Reno/Sparks,...
Establishing a Drought Reserve Policy for the Monterey Peninsula Water Management District
The Monterey Peninsula Water Management District was created by the California Legislature in 1977 for the purpose of developing an integrated management program for all of the water resources...
Development of a Two-Layered Groundwater Model for the Taipei Basin
The objective of this paper is to develop a groundwater model for flow simulation in the Taipei basin. A conceptual model of the basin is first developed; the model consists of an upper...
Development of San Gorgonio Pass Groundwater Flow Model I. Model Calibration
A groundwater flow model is being developed for use in management of a planned groundwater storage and recovery program for the Beaumont Storage Unit of the San Gorgonio Pass groundwater...
Mathematical Modeling of the Sacramento-San Joaquin Delta
The Sacramento-San Joaquin Delta consists of a complex network of interconnected channels, open bodies of water, dead-end sloughs, export pumps, reservoirs, tide gates and irrigation pumps....
A Unified Optimization?Simulation Aquifer Management Model
The optimal management scenario for a groundwater production system represents a delicate balance between the water production operational schedule, which will result in the least demand...
San Francisco Bay and Delta Oil Spill Fate Studies Part II: Oil Spill Simulation
Because of the presence of oil refineries and significant tanker and barge traffic in the bay and delta region, the possibility of a moderate or major spill in the area must be considered....
Simulation of River Bed Evolution Below Tsengwen Reservoir in Taiwan
An uncoupled, one-dimensional river model, capable of simulating bed evolution, hydraulic sorting and armoring under unsteady flow conditions is presented in this paper. This unsteady...
On the Applicable Ranges of Kinematic and Diffusion Models in Open Channels
The kinematic and diffusion models using simplified momentum equations of the full dynamic equation have been frequently used for numerical flow simulations, because they have several...
Simulating THM Precursors Transport with DWRDSM
A study was conducted by the California Department of Water Resources (DWR) to demonstrate the ability of its Delta Simulation Model (DWRDSM) to simulate fate and movement of inorganic...
