“…Hence, it is necessary to consider all these factors, to understand groundwater recharge potential of an area. The efficient groundwater recharge quantification requires accurate scientific measures and modern techniques [11,12]. The traditional in situ investigations of groundwater recharge potential are time-consuming and expensive [13][14][15].…”

“…Many researchers across the world have carried out groundwater potentiality studies using integrated remote sensing and GIS technique [17][18][19][20][21][22]. An accurate groundwater recharge potential zones mapping in representative semiarid basin can help in resourceful management of this vital source and decrease the groundwater susceptibility in the region [12,23]. Therefore, an effort has been made in this study to define groundwater recharge potential zones of Shivganga watershed using MCDA, in preparation of groundwater development plan.…”

Groundwater recharge potential (GWRP) plays a vital role as it directly or indirectly supports domestic, agriculture and industrial activities by infiltrating the rainwater. The present paper touches upon the methodology delineating groundwater recharge potential zones by applying geospatial and multi-criteria decision analysis (MCDA) to the derived thematic layers based on significant influence of occurrence of groundwater in semiarid watershed of Western India. The satellite imageries and other ancillary data were utilized to generate various thematic layers, viz. slope, geology, drainage density, surface run off, geomorphology, land use/land cover soil and vadose zone. The outcome of study shows that about 24.69% is having high GWRP and 24.17% of the area is moderate for recharge of groundwater, while the low and poor groundwater recharges potential area is about 44.34% and 6.80% of total area, respectively. The validation of the study was done by overlaying point data groundwater well yield on the output final map; it shows good correlation with result. Also, the surplus water availability was calculated based on vadose calculation according to CGWB method; it shows 17.12 MCM vadose region having artificial recharge of 22.77 MCM. The total recharge is about 117.41 MCM, about 30% of the total runoff, i.e. 35.22 MCM is considered as surplus monsoon runoff available for artificial recharge. The result shows that the use of remote sensing, geospatial and MCDA technologies are promising and efficiently recognize the suitable regions for groundwater recharge over other conventional techniques.

Land suitability analysis (LSA) for afforestation is an approach that stands amongst the most able frameworks revealing the concern for cultivable land and predicting the availability for sustainable development in semi-arid areas. In view of this, the objective of the present study is to propose a conceptual procedure for LSA that would help enhancing the green cover to combat environmental threats rendering groundwater recharge. LSA involves various thematic layers such as distribution of land use/landcover, slope, soil depth, soil type, pH, soil calcium, soil magnesium, sodium, bulk density, organic matter, boron and runoff that have been derived using satellite images and collateral data. Food and Agriculture Organization framework and guidelines have been followed for LSA and it has been found that only 9.16% land is 'highly suitable', 14% of land is 'moderately suitable' whereas, marginally suitable lands for afforestation are estimated about 14% of total area and non-suitable areas for afforestation are about 61% of the total area. The multi-parametric based decision making AHP tool integrated with GIS proposes a novel methodology and outcomes of the research could be useful to identify suitable lands for agriculture in any various parts of the world.

“…Rajasekhar et al [9] in a semi-arid area in southern India, identified suitable areas for the construction of rainwater harvesting works by calculating the region runoff potential. Baalousha et al [10] estimated the rain contribution to groundwater recharge in an arid area, using a water balance where runoff was estimated with CN method; furthermore, Santhanam and Abraham [11] estimated the precipitation contribution to groundwater recharge in a 323 km 2 basin in India using the water balance method.…”

Through the implementation of geographic information systems (GIS) and images of the study area obtained by remote sensors, the curve number method (NC) was implemented in this research, in order to determine potential recharge zones in two micro-basins in the aquifer region called Zona Bananera, located in the department of Magdalena in Northern Colombia. Potential infiltration of the area was estimated and the hydrological response for precipitation events with different return periods was evaluated. The predominant hydrological soil groups were found to be A and B, with 77.4% (84115.2 ha) in the Sevilla River micro-basin and 81.6% (7466.1 ha) in La Aguja micro-basin. The Sevilla River micro-basin showed both the best water regulation and enhancement of the infiltration process, evidenced by the existence of low as well as medium values of curve number and potential surface runoff. The highest values of potential runoff were in the middle and lower part of the micro-basins, where there are extensive areas covered with banana crops; indicating that anthropic intervention is a determining factor in the area’s hydrological response. Under current conditions, the micro-basins show a minimal risk of erosive processes for rainfall with return periods of less than 5 years, due to runoff occurrence of less than 100 mm. Within the study area, it was found that approximately 3380 hectares show favorable conditions to contribute to the recharge of the Zona Bananera aquifer, making it a strategic conservation area.
