In this paper an algorithm for analysis and design of a structured irrigation network and a traditional irrigation network are developed on the basis of the gradually varied flow analysis of the flow in the entire network. The model developed brings advantages of the structured irrigation network concept and also allows the user to analyses and design the flow distribution in the entire network. Model built around the gradually varied flow analysis model with a tree network is divided into a group based on network consisting of an initial value problem and also a boundary value problem with junctions as the reconciled boundaries. The essence of the model is that it can handle several types of structures such as head regulators, duckbill weirs in the main canal, an open flume, a pipe semi module, a pipe outlet with and without a sleeve, proportional distributors and tail clusters in the offtakes. These structures are very important from the standpoint of analysis and design for successful implementation of a structured irrigation network on an existing system and also for analysis and design of a traditional irrigation system consisting of many gates and other structures. The focus of this paper is the efficacy of the water management in ensuring equitable distribution of flow at different discharges released at the head works.

结构化灌溉网络中的渐变流量计算

本文在对全网流量逐渐变化的流量分析的基础上，提出了一种结构化灌溉网络和传统灌溉网络的分析设计算法。开发的模型带来了结构化灌溉网络概念的优势，也允许用户分析和设计整个网络中的流量分布。围绕逐渐变化的流分析模型建立的模型以树状网络为基础，基于网络分为一组，由初始值问题和以连接点为协调边界的边值问题组成。该模型的本质是它可以处理水头调节器、主渠鸭嘴堰、明水槽、管道半模块、带套管和不带套管的出水口等几种类型的结构，分包中的比例分配器和尾部簇。从分析和设计的角度来看，这些结构对于在现有系统上成功实施结构化灌溉网络以及分析和设计由许多闸门和其他结构组成的传统灌溉系统非常重要。本文的重点是水管理在确保水头厂排放的不同排放量中公平分配流量的有效性。
