这处世界遗产包含了5个阿夫拉贾（Aflaj）灌溉体系，同时也是3000个在阿曼仍然使用中的系统的典型代表。这种灌溉系统的由来可以追朔到公元500年左右，但是从考古学上的证据来看，这个应用在极端干燥地区的灌溉系统应该早在公元前2500年就已经存在。Aflaj是falai的复数形式，在传统阿拉伯语中的意思是公平地划分珍贵的稀有资源，以确保能永续性地维持这种灌溉系统的特征。在水资源方面则是利用重力，从地底或涌出的山泉中将水导出，用来供应家庭用水以及农业灌溉所需，这种灌溉系统通常能供应数公里以上的距离。至于村落及城镇间如何公平且有效的管理及分配水资源的机制，至今依然建立在彼此间的信赖和公共利益上，并且透过大量的观测数据来引导。同时这里建造了为数众多的瞭望台来保护水资源系统，从列入遗产的某些部分可反映出社区对阿夫拉贾体系的历史性依赖。其他被包含在该遗迹的建筑还有清真寺、房屋、日晷以及拍卖水的大楼。由于受到地下水水层持续下降的威胁，阿夫拉贾灌溉系统代表一种被保护得极好的土地使用形式。

The property includes five aflaj irrigation systems and is representative of some 3,000 such systems still in use in Oman. The origins of this system of irrigation may date back to AD 500, but archaeological evidence suggests that irrigation systems existed in this extremely arid area as early as 2500 BC. Using gravity, water is channelled from underground sources or springs to support agriculture and domestic use. The fair and effective management and sharing of water in villages and towns is still underpinned by mutual dependence and communal values and guided by astronomical observations. Numerous watchtowers built to defend the water systems form part of the site reflecting the historic dependence of communities on the aflaj system. Threatened by falling level of the underground water table, the aflaj represent an exceptionally well-preserved form of land use.
