Integrated analysis of hydro-geomorphology is a vital aspect of locating groundwater perspective zones. It also provides a systematic approach to groundwater evaluation and promotes the sustainable development of resources. This study employed geospatial techniques to obtain the hydro-geomorphology of Medchal Mandal, located in the North-East direction of Hyderabad. The following analysis has been summarized from the study; (1) pediplain (5184.59 ha), which is moderately weathered, found the groundwater prospects in this zone ranging from poor to moderate (2) Pediplain shallow weathered (6066.10 ha), and noticed the groundwater condition varying from moderate to poor noticed (3) pediment (1554.75 ha) to hold moderate groundwater (4) pediment inselberg complex (5614.06 ha), was located in the study implied poor groundwater conditions (5) denudation hills (161.82 ha) has a groundwater potential ranging from poor to negligible and noticed that the cause for poor groundwater conditions was significant runoff produced and mild infiltration. Lineaments were identified in the following villages, Gaudavalli, Gosaiguda, Ghanpur, Sreerangavaram, and Nuthankal, indicating major orientations along with N-S and NE, SW, and SE directions. In the study area, the observed groundwater resource was found acceptably satisfactory. Furthermore, the thematic maps of hydro geomorphology and geomorphology showed possible artificial recharge areas that can be employed alternatively to manage groundwater resources in the study area about complex rock terrain localities. Using the multi-influence factor (MIF) and weighted overlay techniques in Arc GIS, the eight layers were created and given set scores and weights based on their propensity to hold water. The results can be paragraphed as three zones visible on spatial exposure (a) 28% good groundwater potential zone, (b) moderate (33%), and (c) poor (39%) were evaluated. Thus, the groundwater potential model is a predominant tool for assessing sustainable groundwater resources.

Unprecedented rainfall events cause increased problems of critical urban flooding. Urban flooding has emerged as a severe problem causing damage to properties, automobiles, and death risks. Inadequate drainage facilities, less infiltration, and increased impervious surface due to random urbanization are the leading causes of urban flooding. In our study, we selected Data Ganj Baksh Town (DGBT) in Lahore city to investigate the locations of urban flooding and provide potential suggestions for groundwater recharging. The elevation data points at different locations within DGBT were collected with a GPS device, utilized for generating a digital elevation model using Geographic Information System (GIS). Slope analysis and contour analysis were also carried out on GIS to estimate the direction of water ponding locations and surface depressions. These analyses in maps helped identify potential groundwater recharge locations in selected towns. Rainwater harvesting and recharging wells have been proposed in this study. Short cost estimation of groundwater recharge and rainwater harvesting has also been performed on these techniques.

The present study shows the groundwater potential assessment and an effective management of the groundwater resources in Bostanlik district, Uzbekistan based on the integrated utilization of remote sensing and GIS techniques. For the current study, various thematic spatial layers such as soil map, geology map, land use/land cover (LULC), elevation, slope, stream proximity, stream density, curvature, topographic wetness index (TWI) and precipitation are used to delineate groundwater potential zones. GIS based multi-criteria decision analysis (MCDA) was applied. The percentage of groundwater potential zones identified using given factors is shown as 6%, 45%, 26%, 13%, and 10% respectively from very high to very low classes. High and very high probability of groundwater existence occurs within or across the Charvak reservoir and along the Chirchik river. Territories, covered by mountains have low and very low potential of groundwater resources. The rest of the territory has moderate potential for groundwater resources. For the validation of obtained results we have used 31 observed spring locations. Results of overlaying the final map with spring locations shows relatively high accuracy rate. The results of the research can be helpful for determining potential groundwater reserves of the Bostanlik district.

Assessment of groundwater conditions particularly its potential for sustainable groundwater management is a major concern for agriculture, domestic, and industrial water security. The rapid growth in population and urbanization impose to the high demand of water for drinking as well as for irrigation propose in quaternary aquifers in Ganga Plains and over-exploitation of groundwater resources for drinking and irrigation purpose causes a high rate of water level depletion in Ganga plains. The aim of the present work to develop the integrated groundwater recharges potential using geographical information system (GIS) and analytic hierarchy process (AHP) techniques. The important biophysical and hydrogeological factors influencing the groundwater recharge considered are hydrogeomorphology, geology, LULC, depth to water level, rainfall, soil texture, NDVI, and slope. Thereafter, all the parameters were integrated into a GIS environment for developing the groundwater recharge suitability assessment. Multicriteria decision-making model used to develop the groundwater recharge suitability maps and classified into four zones with varying spatial coverage from very high (15%), high (63%), moderate (20%), and poor (2%). The groundwater recharge suitability zones were also validated with actual bore well yield data of the study area for each recharge suitability zones. Results of integrated geoinformatics and spatial decision-making techniques are a very useful scientific tool for groundwater recharge assessment of Indo-Gangetic Plains for assessment of suitable recharge techniques and locations for future groundwater sustainability and action plan.

The upstream of the Cisadane Watershed is included in the Mount Halimun Salak National Park area as the water catchment area. Water resource conservation is important because of land use change. Rainfall analysis was carried out to determine the rain intensity amount. Then, infiltration observations were also carried out in Ecosystem Restoration (ER) areas. ER is an area in the rehabilitation zone that requires improvement, especially in biophysical improvement. Several ER areas are in Cibunian Village and Purwabakti Village. The analysis determined the infiltration rates in the ER areas. Field surveys carried out data collection on infiltration sample measurements. Sample points were selected using Stratified Random Sampling. The results show the average rainfall in the study area is around 3950 mm/year. The results show the infiltration ability in the ER area is relatively slow. However, there are still results of rapid infiltration at several sample points. Due to limited water absorption capacity, soil characteristics with clay texture influence slow infiltration conditions. Even though the rainfall is high, surface water runoff is quickly formed. The rainfall in the Cisadane watershed should be stored to reserve water supply, especially during the dry season. In detail, water storage can be an infiltration pit, artificial water storage tanks, reservoirs, or ponds. The limited availability of water resources challenges water uses in the Cisadane Watershed. This research is essential as an initial study to find out more about the watershed hydrological system and the water demand level.
