Hydraulic testing of specialised water production structures (horizontal collector well) in riverbank filtration systems
Kulcsszavak:horizontal collector well (HCW), riverbank filtration, drinking water supply
One of Hungary's strategic water sectors is the supply of drinking water, which relies heavily on so-called riverbank filtration systems. About 35-40% of the national drinking water supply comes from riverbank filtered aquifers. Today in Hungary, 40% of the population; nearly four million people's daily water needs are met from riverbank filtered aquifers. In the future, 75% of our drinking water sources will be bank-filtered, which means that they will also be of great importance for future water resource management.
The main water abstraction device in these aquifers is the well, or a special type of well, the horizontal collector well (HCW). In our work, we will focus on the hydraulic investigation of these types of wells. Using modern modeling software, the impact of the special design of HCWs on groundwater flow conditions can be well modeled. In our work, the yield distribution between the arms and the impact on the potential relationships are discussed in more detail and the results of this modeling are presented.
