Water is essential for irrigation, drinking and industrial purposes from global to the regional scale. The groundwater considered a signifcant water resource specifcally in regions where the surface water is not sufcient. Therefore, the research problem is focused on district-wise sustainable groundwater management due to urbanization. The number of impervious surface areas like roofng on built-up areas, concrete and asphalt road surface were increased due to the level of urban development. Thus, these surface areas can inhibit infltration and surface retention by the impact of urbanization because vegeta tion/forest areas are decreased. The present research examines the district-wise spatiotemporal groundwater storage (GWS) changes under terrestrial water storage using the global land data assimilation system-2 (GLDAS-2) catchment land surface model (CLSM) from 2000 to 2014 in West Bengal, India. The objective of the research is mainly focused on the delineation of groundwater stress zones (GWSZs) based on ten biophysical and hydrological factors according to the defciency of groundwater storage using the analytic hierarchy process by the GIS platform. Additionally, the spatiotemporal soil moisture (surface soil moisture, root zone soil moisture, and profle soil moisture) changes for the identifcation of water stress areas using CLSM were studied. Finally, generated results were validated by the observed groundwater level and groundwater recharge data. The sensitivity analysis has been performed for GWSZs mapping due to the defcit of groundwater storage. Three correlation coefcient methods (Kendall, Pearson and Spearman) are applied for the interrelationship between the most signifcant parameters for the generation of GWSZ from sensitivity analysis. The results show that the northeastern (max: 1097.35 mm) and the southern (max: 993.22 mm) parts have high groundwater storage due to higher amount of soil moisture and forest cover compared to other parts of the state. The results also show that the maximum and minimum total annual groundwater recharge shown in Paschim Medinipore [(361,148.51 hectare-meter (ham)] and Howrah (31,510.46 ham) from 2012 to 2013. The generated outcome can create the best sustainable groundwater management practices based upon the human attitude toward risk.

Water-table levels in the Kamienna River drainage basin, SE Poland, are presently measured at 14 observation points within the groundwater observation-research network of the Polish Geological Institute – National Research Institute, included in the monitoring programme during the period 1979–2007. They exhibit multi-year changes in groundwater storage near the observation points. The best documented cycle is that for the period 1982–2002, observed in the wells monitoring water in fractured-karstic formations, where the amplitude of the water-table level was 45 m at that time. The retention balance in the cycle was negative. At the beginning of the cycle, the water table in the fractured-karstic aquifers was 1.40 to 1.94 m higher than at the end. Further observations of the multi-year changes in retention will be the basis for possible corrections to calculations of groundwater resources in this drainage basin, as well as for model predictions of resources, performed for water management in connection with potential climate change.

Ogólny dopływ wody do kopalni złożony jest z wielu składowych W pracach badawczych prowadzonych przez autorów wykorzystywano materiały pomiarowe dotyczące ilości odprowadzanych z kopalń wód o bardzo różnej jakości i różnej częstotliwości wykonywania. W związku z tym zachodziła konieczność opracowania metod wyznaczenia poszczególnych składowych dopływu, dostosowanych do posiadanych danych hydrogeologicznych. W niniejszej pracy opisano metody wyznaczenia poszczególnych składowych dopływu ogólnego do kopalń. Składowe te zostały wyznaczone i przedstawione na schematach załączonych do niniejszej pracy. Z omówienia wyłączono jedynie metody badań modelowych. Niektóre z prezentowanych metod obliczeń opisano w literaturze naukowej po raz pierwszy.

The total water inflow to a mine consists of many elements. In research authors used different data of water amount which was pumped from mines. In case of this it was necessary to compile the methods of definition of several inflow elements, which are compatible with possessed hydro geological data. In this paper all methods of definition of several elements of total inflow to mines are presented. These elements were defined and shown on schemes which are included in this paper.
