REAL-TIME MONITORING TO ASSESS THE IMPACT OF GROUNDWATER LEVEL CHANGE ON THE ECOSYSTEM IN BANGLADESH AQUIFERS

Groundwater level monitoring and data acquisition are effective pre-requisite tools for water resource management. Because of the complexities of groundwater systems, the design and operation of effective groundwater monitoring are difficult. Apposite water level measurements are essential for hydrogeological investigation. The measurement error determines which processes or properties can be resolved; thus, choosing an apt technology becomes critical for any project. Current research highlights the pertinent aspects of monitoring groundwater management and how a viable monitoring system can be developed and operated to its maximum efficiency. The monitoring work included designing the system and collecting, processing, and interpreting data. Several instruments were installed per local regulation and under the ownership of Bangladesh Agricultural Development Corporation (BADC), Barind Multipurpose Authority (BMDA), and Bangladesh Water Development Board (BWDB). This study identified that water levels are under pressure due to climate change, extreme weather conditions, rapid urbanization, excessive groundwater withdrawal, and mismanagement. The SEBA HYDROMETRIE (Germany) indicated that the vented pressure transmitter accuracy is 0.05% of the full scale in Bangladesh Aquifers. Therefore, the proper selection of practical tools will assist in planning and real-time decision-making.
