Optimal design of groundwater monitoring networks using gamma test theory

摘要: Gamma test theory (GTT) is introduced as a novel method to determine the optimal number and location of groundwater monitoring wells without requiring temporal data. This based on calculation statistic, called gamma, for data one period. The are selected such that while they have lowest gamma value, further increase in does not cause much change their value. was applied design an network electrical conductivity (EC) Kish Island, Hormozgan Province, Iran. water EC 55 wells, from 244 existing measured during period Island latitude longitude were recorded. A optimized using GTT-based optimization algorithm. Based results, estimate spatial distribution with maximum achievable accuracy, it necessary monitor at least 110 which identified. Finally, proposed monitored three periods evaluated these periods. Results indicated also optimum can be estimated accuracy wells. current study provides time- cost-effective achieve efficient especially when there limitation.
