Entropy-based grouping of groundwater monitoring network: Groundwater monitoring in Hebei plain
Zhi Chen · Shuiwen dizhi gongcheng dizhi · 2002
The monitoring net with a clear hierarchical structure is essential for water resources evaluation, management and decision\|making. To construct the relationships between monitoring wells, the flow system analysis is recommended because the hierarchy of monitoring network is well corresponded with the hierarchical structures of groundwater flow systems. The monitoring network could be considered as a communicating network. Entropy\|based method is proposed as a tool to re\|grouping those mixed monitoring wells. In this article, the basic concepts about the entropy and information transfer are introduced, and a method based on entropy and information transfer is presented to grouping those monitoring wells of networks. The method is demonstrated in the case study of groundwater level data from Hebei Plain, China, where is the groundwater as the main water supply.
