The Hail Problem
Unlike some other forms of precipitation, hail comes in bursts of short duration, falls over isolated and unpredictable locations, and usually occupies only a small percentage of the total...

Simulation/Optimization Modeling Post-Audits
S/O models have long been used to compute optimal strategies for user-specified optimization problems. It is useful to provide a retrospective of two S/O modeling applications, and how...

Historically, animal waste was considered a valuable fertilizer and thus land was applied for sustainable on-farm production of crops and animals. However, with the shift to large production...

A Paradigm Shift in Irrigation Management
In coming decades, irrigated agriculture will be called upon to produce up to two thirds of the increased food supply needed by an expanding world population. But the increasing dependence...

Better BMP Practices
A study of the professional literature indicates that the meaning of the term BMP, literally signifying a Best Management Practice, has diverged, depending on the professional field. Use...

Modeling Surface Trapped River Plumes: A Sensitivity Study

Subirrigation: Water Table Management
Water table management (subirrigation) is accomplished by controlling the water table, usually through a subsurface drainage system. The crop is subirrigated with water being furnished...

Ecological Risk Reduction for Copper-Based Crop Protectants: A Comparison of Plasticulture with and without Sedimentation Control

Economic Valuation of Agricultural Water Use for Large-Scale Modeling
(No paper) A state-wide irrigated agricultural production model has been developed for California. The model is an extension of the Central Valley Production (CVP) Model that was most...

Use of Economic Optimization to Assess the Value of Water Marketing
(No paper) There is an increasing interest and implementation of water markets as an allocation mechanism for water in the Western U.S. However, the importance of the timing and location...

Vibro-Replacement in Residual Soils for Grain Storage Silos

Predicting with Precision
In many urban areas flood prediction systems are inadequate. Most rely on networks of widely dispersed rain gauges that often fail to provide sufficient geographic coverage to characterize...
