Rhythmic springs are characterized by a rhythmic flow attributable to a hydraulic phenomenon of filling and emptying one or several siphonic reservoirs located upstream of the springs. The M’Chaki spring is the only rhythmic spring in Algeria. The present research was carried out to determine its hydrodynamic functioning on the basis of understanding the hydrodynamic and chemical responses of the spring as well as the geological conditions of the area. Hydrodynamic results indicate that the M’Chaki spring has two types of flow: one is permanent, while the other one is rhythmic, characterized by a cyclicity ranging from 30 min up to 2 h 16 min during the year. Comparison of the spring’s discharge between low and high water periods shows that the discharge of permanent flow varies between 24 and 100 L/s, and the maximum rhythmic flow discharge varies between 70 and 280 L/s, indicating the contribution of rainfalls to supplying the spring. Cycle’s analysis (from 37 up to 60 min) during one day shows that the rhythmic flow is linked to 3 siphonic reservoirs. Hydrochemical study confirmed the obtained hydrodynamic results and indicated that the origin of the permanent water flow is less superficial than the rhythmic water flow. It mentioned also that the siphonic reservoirs were carved in Triassic brecciated formations and highly fractured Liassic carbonate formations. Combining geological, hydrodynamic and hydrochemical data enabled us to propose a conceptual scheme to reveal the disposition of siphonic reservoirs and to explain the functioning of the M’Chaki spring.

有节奏的弹簧的特征是有节奏的流动，这归因于充满和排空位于弹簧上游的一个或几个虹吸器的水力现象。M'Chaki春天是阿尔及利亚唯一的有节奏的春天。本研究是在了解春季的水动力和化学响应以及该地区的地质条件的基础上确定其水动力功能的。流体动力学结果表明，M'Chaki泉水有两种类型：一种是永久性的，而另一种则是有节奏的，其特征是一年中的周期性从30分钟到2小时16分钟不等。比较低水位期和高水位期之间的弹簧流量，可以发现永久流量的流量在24至100 L / s之间变化，最大节流流量在70至280 L / s之间变化，表明降雨对春季的贡献。一天的周期分析（从37到60分钟）显示，节律流与3个虹吸储层相关。水化学研究证实了所获得的水动力结果，并表明永久水流的起源不如有节奏水流那么浅。它还提到虹吸储层是在三叠纪的角砾岩地层和高度断裂的碳酸锂岩地层中雕刻的。结合地质，水动力和水化学数据，使我们能够提出一个概念方案，以揭示虹吸储层的布置并解释M'Chaki泉的功能。表明降雨对春季的贡献。一天的周期分析（从37到60分钟）显示，节律流与3个虹吸储层相关。水化学研究证实了所获得的水动力结果，并表明永久水流的起源不如有节奏水流那么浅。它还提到虹吸储层是在三叠纪的角砾岩地层和高度断裂的碳酸锂岩地层中雕刻的。结合地质，水动力和水化学数据，使我们能够提出一个概念方案，以揭示虹吸储层的布置并解释M'Chaki泉的功能。表明降雨对春季的贡献。一天的周期分析（从37到60分钟）显示，有节奏的流动与3个虹吸储层相关。水化学研究证实了所获得的水动力结果，并表明永久水流的起源不如有节奏水流那么浅。它还提到虹吸储层是在三叠纪的角砾岩地层和高度断裂的碳酸锂岩地层中雕刻的。结合地质，水动力和水化学数据，使我们能够提出一个概念方案，以揭示虹吸储层的布置并解释M'Chaki泉的功能。水化学研究证实了所获得的水动力结果，并表明永久水流的起源不如有节奏水流那么浅。它还提到虹吸储层是在三叠纪的角砾岩地层和高度断裂的碳酸锂岩地层中雕刻的。结合地质，水动力和水化学数据，使我们能够提出一个概念方案来揭示虹吸储层的布置并解释M'Chaki泉的功能。水化学研究证实了所获得的水动力结果，并表明永久水流的起源不如有节奏水流那么浅。它还提到虹吸储层是在三叠纪的角砾岩地层和高度断裂的碳酸锂岩地层中雕刻的。结合地质，水动力和水化学数据，使我们能够提出一个概念方案，以揭示虹吸储层的布置并解释M'Chaki泉的功能。
