Mohammad Tofayal Ahmed from the University of Science and Technology performed a hydrogeological investigation of the south-eastern coastal aquifer of Bangladesh. The dataset includes results from step-drawdown tests on four single wells, analyzing well performance, aquifer transmissivity, and lithological data. The study identified the aquifer as Early Miocene age, consisting of Upper and Middle Boka Bil formations.
Use Cases
- Evaluating well efficiency based on reported well loss percentages (17% to 19.8%) and aquifer loss percentages (80.2% to 82.6%).
- Estimating aquifer transmissivity based on reported values ranging from 263.3 to 271.24 m²/day.
- Assessing specific capacity for water production based on values ranging from 18.13 to 23.79 m³/day/m.
- Characterizing hydrostratigraphy based on lithological data analysis indicating Early Miocene age formations.
Strengths
- Includes specific quantitative results from step-drawdown tests, such as well efficiency values ranging from 95.3% to 98.5%.
- Provides aquifer transmissivity estimates (263.3 to 271.24 m²/day) and specific capacity values (18.13 to 23.79 m³/day/m).
- Identifies the geological age (Early Miocene) and formation (Boka Bil) of the studied aquifer.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Last update date is unknown; freshness unverified.
