“…Further, de Silva and Rushton [16] applied this approach when studying rice fields in the tropical climate of Sri Lanka. Rushton et al [23] recently used this method to estimate recharge in a multi-aquifer system of north-west Bangladesh. However, the applicability of soil moisture balance techniques in semiarid regions has been questioned as often the magnitude of recharge is often comparatively less than the other variables such as evapotranspiration [5,24,25].…”

“…However, the applicability of soil moisture balance techniques in semiarid regions has been questioned as often the magnitude of recharge is often comparatively less than the other variables such as evapotranspiration [5,24,25]. This can be overcome if the recharge is estimated using daily time steps coupled with an understanding of near-surface processes in the soil zone and subsequent water movement through underlying strata [18,23].…”

In the semiarid regions of India, the annual rainfall is very low (~650 mm) and erratic; hence groundwater recharge is vital to support crops, especially in the winter season. For groundwater budgeting it is essential to consider how groundwater recharge is affected by both land-use and rainfall distribution. This study used a soil water balance approach, considering hydrological, meteorological, hydrogeological and crop information to understand the recharge process in semiarid regions. The approach was used at a sub-watershed scale where farmers grow rainfed and irrigated crops. Delayed recharge response on the water table was considered to estimate actual recharge, which closely matches the observed water levels in the field. The recharge estimated in rainfed agricultural lands, rainfed-irrigated agricultural lands, and barren lands was 29%, 17%, and 31% of the total inflow.

“…The use of groundwater in the irrigation sector for crop production is increasing significantly in Bangladesh. In such a case, the northwest region of Bangladeshis is facing the critical condition of groundwater due to the impact of over-exploitation. Abstraction of groundwater from deep tube wells has resulted in substantial increases in agricultural production and significant falls in aquifers' groundwater heads (Patle et al 2015;Rushton et al 2020;Mallick et al 2021). More than 75% of irrigation water is managed by the groundwater withdrawal in the northwest part of Bangladesh .…”

Groundwater resource plays a crucial role for agricultural crop production and socio-economic development in some parts of the world including Bangladesh. Joypurhat district, the northwest part of Bangladesh, a crop production hub, is entirely dependent on groundwater irrigation. A precise assessment and prediction of groundwater level (GWL) can assist long-term GWR management, especially in drought-prone agricultural regions. Therefore, this study was carried out to identify trends and magnitude of GWL fluctuation (1980-2019) using the Modified Mann-Kendall test, Pettitt's Test, and Sen Slope estimators in the drought-prone Joypurhat district, northwest Bangladesh. Time-series data analysis was performed to forecast GWL from 2020 to 2050 using the Auto-Regressive Integrated Moving Average (ARIMA) model. The findings of the MMK test revealed a significant declining trend of GWL, and the trend turning points were identified in the years 1991, 1993, 1997, and 2004, respectively. Results also indicate that the declining rate of GWL varied from 0.104 m/yr to 0.159 m/yr and the average rate of GWL declination was 0.136 m/yr during 1980-2019. The outcomes of wavelet spectrum analysis depicted two significant periods of the declining trend in Khetlal and Akkelpur Upazilas. The results obtained from the optimal identified model ARIMA (2,1,0), indicating that GWL will decline at a depth of 13.76 m in 2050, and the average declination rate of GWL will be 0.143 m/yr in the study area. The predicted results showed a similar declining tendency of GWL from 2020 to 2050, suggesting a disquieting condition, particularly for Khetlal Upazila. This research would provide a practical approach for GWL assessment and prediction that could help decisionmakers implement long-term GWR management in the study area.

“…It is particularly important in regions with large demands for groundwater supplies, where such resources are the keys to economic development (for example, Barind area (north-western part) of Bangladesh). Groundwater table in Barind area of Bangladesh is declining rapidly due to irrigated area expansion, industrial demand, and drinking purposes [2]- [4]. Due to decrease of surface-water availability as a result of storage siltation, climate vagaries, and structural measures in the major river systems etc., the pressure on groundwater resource is increasing day by day.…”

For proper management of groundwater resources, estimation of groundwater recharge is crucial. Information on groundwater recharge is particularly important in dry areas where groundwater is continuously depleting. In this study, groundwater recharge was estimated at two locations in the dry, Barind area of Bangladesh using the applied tracer, water balance (WB) and water-table fluctuation (WTF) methods. In the WTF method, considerations for drinking and irrigation withdrawal were taken. For runoff estimation in the WB method, a modified form of the USDA-SCS method was used. The results revealed that the average yearly recharge at the Nachol location varied from 104.9–195.8 mm/year under different methods, having a mean of 136.1 mm/yr over the methods. At Niamatpur location, the recharge rate varied from 125.1 to 210 mm (9.9 – 15.1% of yearly rainfall) under different methods, having a mean of 157.6 mm/yr. On average, the WTF method produced the lowest estimate of recharge followed by WB method. Based on the local geological and hydrological settings and the suitability/limitations of the methods themselves, the tracer technique may be regarded as a reliable method for the study area. The information on recharge will help the ‘water resource agency’ and ‘policymakers’ to adjust pumping/irrigation schemes, avoid over-exploitation of the groundwater resource, and ensure the long-term sustainability of the resource in the area.
