Abstract: The adjustment of structures along irrigation free-surface systems aims to achieve, or maintain, a targeted status of the canal network. The interaction between structures and reaches is an important aspect of canal control ...

Abstract: Analytical relationships between the control of canal water depth, the sensitivity of irrigation delivery structures, and the resulting internal performance are established at the system level. One system sensitivity ...

Abstract: Assessment of the surface storage is of great importance in hydrological surface irrigation. For the Horton infiltration law used in the ALIVE model (Advanced LInear VElocity), an accurate measurement of surface storage ...

Abstract: Previously, surface irrigation hydraulic models used the principle of mass conservation to simulate the advance of water along the field and to solve the inverse problem of finding the infiltration function from measurements ...

Abstract: A flow‐balance equation of surface irrigation is used to solve, section by section, the advance problem on heterogeneous soils. The advance‐linear‐velocity (ALIVE) solution as a function of time is a sum of exponential ...

Abstract: This article is an attempt to develop an analytical framework to address sensitivity of irrigation offtakes. The perturbation of water depth and the deviation of the setting are considered for analysis. Sensitivity of ...

Abstract: One of the basic assumptions of the hydrological volume balance models in surface irrigation implies that furrow inflow instantaneously increases to a constant rate: the step-flow condition. Unfortunately this assumption ...

Abstract: The flow behavior along an open-channel irrigation network can be assessed by determining the sensitivity of the irrigation structures. The importance of governing factors of the sensitivity and proportionality indicators ...
