Hydroinformatics is a technology that combines information and communications technologies together with various disciplinary optimization and simulation models that focus on the management of water. This paper reviews the historical development of hydroinformatics and summarizes the current state of this technology. It describes the range of modeling tools and applications currently described in hydroinformatics literature. The paper concludes with some speculations about possible future developments in hydroinformatics.

“…These lineaments varied in length from 0.45 km to 9.6 km and had different orientations, including N-S, NE-SW, E-W, and SE-NW. A total of 22 lineaments were identified, of which 16 were minor (2-10 km), and 6 were micro (less than 2 km) lineaments (Table 2) (Sitharam et al 2007;Venkateswara et al 2021).…”

“…Geophysical methods, such as resistivity surveys, have been widely adopted to solve various hydrogeological problems in hard rock terrains (Ammar and Kruse, 2016;Kang et al 2018;Deng et al 2020;Rustadi et al 2022). Surface geophysical measurements, along with remote sensing, can determine several parameters characterising water-bearing formations (Venkateswara et al 2021). The resistivity survey is particularly popular low-cost (Sathiyamoorthy and Ganesan, 2018), providing good contrast in resistivity measurements of water-saturated and non-saturated rock formations (Loke et al 2013, Subrahmanyam andVenkateswara, 2017b;Venkateswara et al 2019b).…”

This study aimed to explore groundwater potential zones in the EGMB of Alluri Seetharama Raju district, Andhra Pradesh, India, for drinking and agriculture purposes. To achieve this goal, 72 Vertical Electrical Soundings (VES) were conducted using the Schlumberger electrode configuration. The resistivity sounding data were analyzed to determine the aquifer thickness, basement depth, Dar-Zarrouk parameters, and aquifer transmissivity. Spatial distribution maps were generated for these parameters to understand the subsurface formation. The analysis revealed a linear groundwater potential zone (8.46 km 2 ) in the eastern part of the study area, extending in the NNE-SSW direction for 9.6 km. Six VES locations (P24, P27, P29, P30, P33, and P38) in this zone exhibit good potential (>30 m aquifer thickness), while the three VES locations (OP19, P5, and P46) in the central region are recommended for drilling bore wells. Additionally, moderate aquifer thickness (20-30 m) are identified in other VES locations (OP14, OP20, P4, P10, P12, P13, P15, P17, P18, P31, P46, and P50) along streams in the western and central part of the area, which can yield reasonable quantities of water. This information is useful for groundwater exploration and watershed management to meet the demands of tribal population in the study area.
