Mapping of groundwater potential zones across Ghana using remote sensing, geographic information systems, and spatial modeling by Gumma, Murali K., Pavelic, Paul

“…Groundwater potential zones were delineated using remote sensing and geographical information system (GIS) techniques drawing from a database that includes climate, geology, and satellite data. Subjective scores and weights were assigned to each of seven key spatial data layers and integrated to identify groundwater potential according to five categories ranging from very good to very poor derived from the total percentage score. …”

Potential of MODFLOW to model hydrological interactions in a Semikarst floodplain of the Ozark Border Forest in the Central United States by Chinnasamy, Pennan, Hubbart, J.A.

“…The current study approach is novel with regard to the use of transient flow conditions (as opposed to steady state conditions) in underrepresented semikarst geological systems of the U.S. Midwest. This study emphasizes the significance of semikarst geology in regulating SW–GW hydrologic and nutrient interactions and provides baseline information and modeling predictions that will facilitate future studies and management plans.…”

The last natural seasonal forests of Indonesia: implications for forest management and conservation by Laumonier, Y., Nasi, R.

“…The largest is the flat Yamdena (7°36′ S, 131°25′ E).Vegetation was interpreted from LANDSAT satellite data, overlaid with geology and topography for pre‐stratification. Within each strata, forest sites were equally systematically sampled using a network of small 0.2 ha survey plots (60 plots, 7,130 trees) and soil pits sampled for 44 of the vegetation plots. …”

Global mapping of volumetric water retention at 100, 330 and 15 000 cm suction using the WoSIS database by Turek, Maria Eliza, Poggio, Laura, Batjes, Niels H., Armindo, Robson André, Jong van Lier, Quirijn de, Sousa, Luis de, Heuvelink, Gerard B.M.

“…The point data was combined with around 200 environmental covariates describing vegetation, terrain morphology, climate, geology, and hydrology using DSM. In total, we used 7292, 33 192 and 42 016 SWR point observations at 100, 330 and 15 000 cm, respectively, and complemented the dataset with 436 108 estimated values at each suction. …”

Development of a tool for managing groundwater resources in semi-arid hard rock regions: application to a rural watershed in South India by Dewandel, B., Perrin, J., Ahmed, S., Aulong, S., Hrkal, Z., Lachassagne, P., Samad, Madar, Massuel, S.

“…Recent research studies have shown that when hard rocks are exposed to regional and deep-weathering processes and when the geology is relatively homogenous, a typical hard rock aquifer is made of two main superimposed hydrogeological layers each characterized by quite homogeneous specific hydrodynamic properties: namely the saprolite and the fissured layers. …”
