Optimal Control of the West Parisian Area Water Supply Network
The West Parisian Area regional office of Lyonnaise des Eaux has been equipped with computer-aided optimal decision-making software, using daily water demand forecasts. This tool calculates...
Computerized Operation of Water and Urban Networks: From Digital Mapping to Integrated Information Systems
Advances in computer hardware and software have provided the opportunity for development of powerful technical information systems (TIS) for municipal water supply and distribution services....
Experience With a Water Distribution System Model
The City of Santa Cruz has a water distribution system covering approximately 30 square miles (78 km2) and serving 75,000 people. The population...
Graphical Canal Model for System Operators and Planners
Contra Costa Water District operates the Contra Costa Canal, part of California's Central Valley Project. Hydrocomp, Inc. developed an interactive graphical model of the canal...
Input Processor Package for Water System Studies
An input processor package for a water distribution simulation model has been developed and field tested. This preprocessor enables users with little or no computer use experience to directly...
IRSIS, A Software Package for Irrigation Scheduling
IRSIS (IRrigation Scheduling Information System) has been developed to solve problems concerning irrigation scheduling at field level. For a given climate, crop and field it offers the...
Optimal Real-Time Pump and Irrigation Scheduling for Center-Pivot Sprinkler Systems
A comprehensive scheduling algorithm is presented for optimally integrating irrigation and pump operational decisions in center-pivot sprinkler systems. Dynamic programming successive...
The State of Art of Physical Modelling of Sediment Transport
The paper attempts formula some ideas about the state of the art in the field of physical modelling of sediment transport processes. Up to now the physics of sediment transport are not...
The State of the Art in Sediment Transport Modelling
The physical understanding and mathematical modelling of the water and sediment motion in rivers, estuaries and coastal waters have made much progress in recent years by various research...
Total Sediment Transport and Its Physical and Mathematical Modeling
Some main results in the field of sediment transport theories obtained by the author are presented. Based on these theories, the methods of physical and mathematical modeling for total...
Quasi-2D Transport and Morphological Forecasting in Large River Systems
Unused potentials of 1D morphological, and transport models were applied to predict not only the longitudinal but also the transverse distribution of concentrations and natural river bed...
Bed Waves Generated by Internal Waves in Alluvial Channels
The flow in an alluvial channel is conceived as a stratified flow both with respect to the velocity- and density-distribution. In such flows internal waves may occur which influence the...
A Tracer-Model for Morphological Simulations of an Estuary
Numerical models for longterm morphological simulations are traditionally based on assumptions like vertical integration of the flow and transport equations and their decoupled treatment....
On the Numerical Simulation of Suspended Sediment Transport in Estuaries
Estuarine fine sediment transport is governed by a wide range of hydrological, chemical and biological parameters including baroclinic circulation, tidal pumping, resuspension, deposition,...
Modeling of Contaminant Transport in Rivers with Emphasis on the Interaction with Movable Boundaries
The transport of dissolved and absorbed pollutants is simulated by a one-dimensional convection-diffusion model which particularly accounts for the exchange processes at the river bed...
Modelling Changes in Coastal Morphology
A description is given of a newly-developed coastal sediment transport model. Features of the model are the inclusion of cross-shore transport and non-potential suspended load, the latter...
Reliability of Bank Protection Works Subject to Erosion
Sediment movement and changes of bed levels in natural rivers are non-stationary processes. The design of protection works for structures against erosion should account for the time dependency...
Channel Entrenchment Along the Post Creek Cutoff in Southern Illinois
The Post Creek Cutoff was constructed in 1915 by the Cache River Drainage Commission to divert flow from the Upper Cache River to the Ohio River. The construction of the cutoff reduced...
