商品描述

Most complex physical phenomena can be described by nonlinear equations, specifically, differential equations. In water engineering, nonlinear differential equations play a vital role in modeling physical processes. Analytical solutions to strong nonlinear problems are not easily tractable, and existing techniques are problem-specific and applicable for specific types of equations. Exploring the concept of homotopy from topology, different kinds of homotopy-based methods have been proposed for analytically solving nonlinear differential equations, given by approximate series solutions. Homotopy-Based Methods in Water Engineering attempts to present the wide applicability of these methods to water engineering problems. It solves all kinds of nonlinear equations, namely algebraic/transcendental equations, ordinary differential equations (ODEs), systems of ODEs, partial differential equations (PDEs), systems of PDEs, and integro-differential equations using the homotopy-based methods. The content of the book deals with some selected problems of hydraulics of open-channel flow (with or without sediment transport), groundwater hydrology, surface-water hydrology, general Burger's equation, and water quality.

Features:

  • Provides analytical treatments to some key problems in water engineering

  • Describes the applicability of homotopy-based methods for solving nonlinear equations, particularly differential equations

  • Compares different approaches in dealing with issues of nonlinearity

大多數複雜的物理現象可以用非線性方程式，特別是微分方程式來描述。在水利工程中，非線性微分方程式在建模物理過程中起著重要作用。強非線性問題的解析解不容易處理，現有的技術是針對特定類型的方程式而設計的，並且只適用於特定問題。從拓撲學中探索同伦的概念，提出了不同種類的基於同伦的方法，用於以近似級數解析解非線性微分方程式。《水利工程中的同伦方法》試圖展示這些方法在水利工程問題中的廣泛應用性。它使用基於同伦的方法解決各種非線性方程式，包括代數/超越方程式、常微分方程式（ODEs）、ODE系統、偏微分方程式（PDEs）、PDE系統和积分微分方程式。本書的內容涉及開渠流（帶或不帶沉積物輸送）、地下水水文學、地表水水文學、一般的Burger方程和水質等一些選定的問題。

特點：
- 對水利工程中的一些關鍵問題提供解析處理
- 描述了基於同伦的方法在解決非線性方程式，特別是微分方程式方面的應用性
- 比較了處理非線性問題的不同方法
