Climate Variability Impact on the Water Resources of Ancient Andean Civilizations
The great ancient empires of South America used corporate irrigated agriculture with centralized control to help hold far-flung domains together. The Inca empire, larger in area than that...
California's Visions of Groundwater: A Water Source and a Salt Sink
Public interest in groundwater resources can be expected to increase. There are few alternative, undeveloped, surface water resources to meet increasing water demand for municipalities....
Multiobjective Optimization of Multireservoir System
In the present study, a detailed multiobjective nonlinear programming model is formulated and applied to a multireservoir system at upper reaches of Krishna river basin in Karnataka State,...
Emerging Concepts for Management of Salinity and Drainage in Irrigated Regions
The purpose of this paper is to very briefly highlight some physical and design concepts important to management of salinity and drainage in irrigated regions in an environmentally sensitive...
Efficiencies of Drainage Systems and Improved Water Management
Drainage of agricultural lands has become a contentious issue as concern increases over the actual economic benefits of subsurface drainage in irrigated regions relative to the impacts...
Vulnerability of Water Resources to Global Climate Change in the Agricultural Midwest- Ecological, Economic, and Regulatory Aspects
As climate changes, so will water resources. General climate change will alter the distribution of hydrometeorological events and will affect water use, in turn resulting in further alterations...
Mexican Border Ground Water Agreement
This paper provides a discussion about the challenges in developing a Mexican Botder Ground Water Agreement for the management of shallow ground waters that connect to the surface water...
Artificial Recharge in the Oakes Test Area
The Oakes Test Area (OTA) was developed to evaluate predicted impacts of developing irrigation in the Garrison Diversion Unit in North Dakota. A limited irrigation water supply has forced...
Effects of Sewage Effluent Irrigation on Paddy
Paddy, the staple food of South India, occupies about an area of 38 million hectares in India [1, 1987]. Being a semi-aquatic plant, its water requirements are many times more than most...
Canal Control and Automation for the Central District System
The Central Nebraska Public Power and Irrigation District system provides irrigation and hydropower benefits in south-central Nebraska. Because of its complexity, the system relies heavily...
Portable Flumes with Adjustable Throats
Vertically adjustable flumes for canal flow measurements address several problems in field practice. One involves the perception by some canal water users that flumes and weirs always...
Design and Implementation of On-Farm Surface Drainage Projects in the Humid Tropics of Mexico
In the humid tropics of southeastern Mexico, the Mexican National Water Commission (CNA) has constructed a network of collector drains for stormwater runoff removal. At the same time the...
Assessment of the Surface-Water Pollution and Measures for Emergency Stations Warning in the Republic of Uzbekistan
In the Republic of Uzbekistan, a special system operates that is designed for the observations on the quality and ecological state of the river ecosystems including: 1-hydrochemical control...
Conjunctive Water Use Transforms a California Desert
An area doing multi-billion dollar recreational and agricultural business in the Southern California Sonoran desert owes its existence and well being to two things—wise water planning...
Economic Efficiency of Regulations for Allocation and Control of Surface Water Withdrawals in Humid Regions
This paper proposes several alternative regulatory instruments for the allocation of flowing water and evaluates these instruments with respect to economic efficiency for a hypothetical...
Modeling 3D Free Surface Flow in Compound Channels: A Validation Case Study
This paper presents the results of a validation study of a free-surface flow model. For the validation, experimental data collected in a compound open channel is used. This validation...
Modeling the Impact of Uncertainty in Spatial Variability of Estuarine Boundary Conditions
Multi-dimensional numerical estuarine models that consider baroclinic forcing require the specification of both the water surface and the water density (salinity and temperature) at the...
Eastern San Joaquin County Groundwater Management
An aquifer system of significant volume is located in Eastern San Joaquin County (ESJC), part of California's Central Valley. The industry in that region is primarily agriculture,...
A New Model of California's SWP/CVP Systems
A water allocation reservoir simulation model is combined with a ground water-surface water simulation model resulting in an integrated model for use in water resource planning studies...
Modeling of Surface Water Pumps in TVA Reservoirs
This paper describes the numerical simulation of surface water pump perforniance at Cherokee and Douglas Dams. The modeling objective was to determine the surface water pump initial velocities...
