“…The basin is a foredeep depression, which has formed in front of the Himalaya as a result of the orogenic uplift and loading, and contains two main basin systems: the Indus basin in the west which deepens longitudinally away from the Himalaya towards the coast; and the Ganges basin in the central and eastern part of the foredeep which deepens transverse to the Himalaya towards the Bay of Bengal (Valdiya 2002;Singh 2007; Fig. 3).…”

“…Collectively these three basin areas form the IGB. Continued convergence of the Indian plate at a rate of 2-5 cm/year, has driven uplift of the basin floor in faultbounded blocks, generating basement highs in several areas of the Ganges basin where basin depth is now less than 1 km and it has affected the position of modern river courses (Singh 2007;Sahu and Saha 2014). Sediment deposition has occurred since Late Cretaceous times with uplift and erosion of the Himalaya (Johnson and Alam 1991;Singh 1996;Alam et al 2003).…”

“…Alluvium grain size: Alluvium grain-size changes from generally coarse gravel and sands (85% sands and gravels), up to boulder-sized, close to the mountain margins of the IGB aquifer and within megafan deposits (Day 1971;Shukla et al 2001;Singh 1996;Singhal et al 2010), to medium sands (70% fine-medium sands) within the central parts of the Ganges and Indus basin plains (Singh et al 1999;Saha et al 2011), to finally silt dominated (70% silts) deltaic deposits in the coastal regions (Goodbred and Kuehl 2000;BGS and DPHE 2001;Acharyya 2005; Fig. 3).…”

“…3). The Pleistocene sediment is also, therefore, comprised predominantly of inter-channel deposits (sand and silt dominated), with clustered (laterally and vertically) coarse channel deposits due to the lower lateral aggradation of the fluvial systems in this part of the basin (Singh et al 1999(Singh et al , 2005a. The sediment contains mainly oxidized coarse sands and silt components (Saha et al 2011).…”

“…At a local scale, aquifer properties can vary significantly over short (100s of m to km's) distances and thicknesses. Low-permeability layers stratify the aquifer, but are rarely continuous over more than a few kilometres (Singh et al 1999;Samadder et al 2011;Srivastava et al 2003), and the anisotropy ratio (i.e. the ratio of vertical to horizontal hydraulic conductivity, Kv/Kh) of the typology varies from approximately <25 in the Upper Indus to 50-100 in the Middle Ganges (Malmberg 1975;Grey et al 1979;Srivastava et al 2003).…”

The Indo-Gangetic aquifer is one of the world's most important transboundary water resources, and the most heavily exploited aquifer in the world. To better understand the aquifer system, typologies have been characterized for the aquifer, which integrate existing datasets across the IndoGangetic catchment basin at a transboundary scale for the first time, and provide an alternative conceptualization of this aquifer system. Traditionally considered and mapped as a single homogenous aquifer of comparable aquifer properties and groundwater resource at a transboundary scale, the typologies illuminate significant spatial differences in recharge, permeability, storage, and groundwater chemistry across the aquifer system at this transboundary scale. These changes are shown to be systematic, concurrent with large-scale changes in sedimentology of the Pleistocene and Holocene alluvial aquifer, climate, and recent irrigation practices. Seven typologies of the aquifer are presented, each having a distinct set of challenges and opportunities for groundwater development and a different resilience to abstraction and climate change. The seven typologies are: (1) the piedmont margin, (2) the Upper Indus and Upper-Mid Ganges, (3) the Lower Ganges and Mid Brahmaputra, (4) the fluvially influenced deltaic area of the Bengal Basin, (5) the Middle Indus and Upper Ganges, (6) the Lower Indus, and (7) the marine-influenced deltaic areas.

The Kathmandu and Banepa Basins, Central Nepal, are located in a large syncline of the Lesser Himalayas. The Older Kathmandu Lake evolved during the Pliocene and early Pleistocene; the Younger Kathmandu Lake, which is the focus of this study, is infilled with late Quaternary sediments. Three formations, arranged in stratigraphical order, the Kalimati, Gokarna and Thoka Formations formed during the infilling stage of this lacustrine basin. Structural and textural sedimentological analyses, a chemical survey across the basin and mineralogical investigations of fine-grained sediments form the basis of this palaeogeographical study. The basin under investigation was covered by a perennial freshwater lake before 30 000 yr BP. The lake was infilled with alluvial and fluvial sediments delivered mainly from the mountains north of the basin. A fairly low gradient was favourable for the formation of diatomaceous earths, carbonaceous mudstones and siltstones, which were laid down in the centre of the lake and in small ponds. Towards the basin edge, lacustrine sediments gave way to deltaic deposits spread across the delta plain. Crevasse splays and anastomosing rivers mainly delivered suspended load for the widespread siltstones and mudstones. The proximal parts of the alluvial-fluvial sedimentary wedge contain debris flows that interfinger with fine-grained floodplain deposits. Three highstands of the water-level (>30 000 yr BP, 28 000-19 000 yr BP, 11 000-4000 yr BP (?)) have been recognised in the sedimentary record of the younger Kathmandu Lake in the Late Quaternary. Second-order water-level fluctuations are assumed to be triggered by local processes (damming by tectonically induced landslides). First-order water-level fluctuations are the result of climatic changes.
