In this paper we present the equation of capture zone for multi-well system in peninsula-shaped confined and unconfined aquifers. The aquifer is rectangular in plan view, bounded along three sides, and extends to infinity at the fourth side. The bounding boundaries are either no-flow (impervious) or in-flow (constant head) so that aquifers with six possible boundary configurations are formed. The well system is consisted of any number of extraction or injection wells or combination of both with any flow rates. The complex velocity potential equations for such a well-aquifer system are derived to delineate the capture envelop. Solutions are provided for the aquifers with and without a uniform regional flow of any directions. The presented equations are of general character and have no limitations in terms of well numbers, positions and types, extraction/injection rate, and regional flow rate and direction. These solutions are presented in form of capture type curves which are useful tools in hands of practitioners to design in-situ groundwater remediation systems, to contain contaminant plumes, to evaluate the surface-subsurface water interaction and to verify numerical models.
在本文中，我们给出了半岛状承压和无压含水层中多井系统的捕获区方程。含水层在平面视图中为矩形，三边有边界，第四边延伸至无穷远。边界边界要么是无流量（不透水）的，要么是入流（恒定水头）的，从而形成了具有六种可能边界配置的含水层。井系统由任意数量的抽水井或注入井或两者的组合组成，具有任意流量。推导了这种井 - 含水层系统的复速度势方程以描绘捕获包络。针对有无任意方向均匀区域流的含水层提供了解决方案。所给出的方程具有通用性，在井的数量、位置和类型、抽注速率以及区域流速和方向方面没有限制。这些解以捕获类型曲线的形式给出，这些曲线是从业者设计原位地下水修复系统、控制污染物羽流、评估地表水 - 地下水相互作用以及验证数值模型的有用工具。
