چکیده

Modern irrigation supply systems have diversified and yet methods of their classification have been overlooked. Thus, each system appears unique and this makes it difficult to integrate experience gained from their analysis. This paper postulates that ‘‘hydraulic command’’ is responsible for their diversification and creates ‘‘generic’’ variations among irrigation systems with each command method making up one class; conversely the systems associatedwith the same class or hydraulic command share the same generic complexities. The benefits of classification aremethodological and include (i) gaining an insight into technical/ management issues associated with each class; (ii) obtaining an overview of generic variations across the classes of these systems enabling integration of knowledge; (iii) explainingmutual incompatibility of the systems associatedwith different commandmethods. RÉSUMÉ Les systèmesmodernes d’alimentationd’irrigation se sont diversifiés, cependant leur classification a été négligée.Chaque systèmeapparaît donc comme unique ce qui rend difficile de tirer parti de l’expérience acquise à partir de son analyse. Cet article postule que la ‘‘commande hydraulique’’ caractérise leur diversification et crée des variations ‘‘génériques’’ parmi les systèmes d’irrigation, chaque méthode de commande constituant une classe; réciproquement, les systèmes associés avec la même classe ou commande hydraulique, partagent les mêmes complexités génériques. Les bénéfices de la classification sont méthodologiques et permettent: (i) d’avoir une idée des problèmes techniques et de gestion associés à chaque classe; (ii) d’obtenir une vue d’ensemble des variations génériques entre les différentes classes de ces systèmes pour permettre une intégration de la connaissance; (iii) d’expliquer l’incompatibilité de systèmes associés à des méthodes de commande différentes.

Optimal groundwater quality management under uncertainty: incorporating the effects of spatial variability of hydraulic conductivity

Uncertainty due to spatial variability of hydraulic conductivity is explicitly incorporated into a procedure for the optimal design of aquifer remediation strategies. The management procedure is based on the stochastic approach to groundwater flow and contaminant transport modelling, in which the hydraulic conductivity is represented as a random field. The remediation design procedure begins wi...

A study of a texture-based equation for estimating the saturated hydraulic conductivity of an alfisol in the sudan savannah ecological zone, Ghana*

Saturated hydraulic conductivities of Varempere series soils (plinthaqualf) located in the sudan savannah zone of Ghana were measured by the falling head method and compared with values estimated by the texture-based equation of Rawls et al. (1982). The comparisons indicated that saturated hydraulic conductivity values estimated using the texture-based equation could predict those measured with...

Basin-scale availability of salmonid spawning gravel as influenced by channel type and hydraulic roughness in mountain catchments

A general framework is presented for examining the effects of channel type and associated hydraulic roughness on salmonid spawning-gravel availability in mountain catchments. Digital elevation models are coupled with grain-size predictions to provide basin-scale assessments of the potential extent and spatial pattern of spawning gravels. To demonstrate both the model and the significance of hyd...

Computer Simulation of Levee’s Erosion and Overtopping Simulation numérique de l'érosion et de la surverse de digues

Improved computer models of erosion have been developed, considering soil hydraulic conductivity. The models deal with erosion of levees, dams and embankments due to overtopping. The simulations trace the formation of rills and gullies, beginning with initial overtopping and continuing to final breaching. Physical models performed at “1-g” and high “g” using a geotechnical centrifuge have been ...

Hydraulic conductance of root and shoot measured with the transient and dynamic modes of the high-pressure flowmeter

The hydraulic conductance (k) of shoots and root systems was measured using the transient and the dynamic modes of the high pressure flowmeter (HPFM). Measurements were conducted on Quercus robur and Fagus sylvatica plants grown on different substrates (forest soil, sand, Terra-green and vermiculite) and harvested at different times of the year. The values of k obtained by the transient mode we...
