  abstract = {{S}tampriet {T}ransboundary {A}quifer {S}ystem ({STAS}) is shared between {B}otswana, {N}amibia and {S}outh {A}frica with massive utilization especially in {N}amibia. {H}owever, the understanding of the comprehensive hydrogeological framework of the aquifer system is limited. {T}his study aimed to develop a comprehensive hydrogeological conceptual model of the aquifer system which mainly entailed 3{D} hydrostratigraphic modelling using {R}ockworks 3{D} geological modelling software, analysis of regional groundwater occurrence and flow system, sources and sinks, hydraulic parameters and definition of {STAS} boundaries. {S}ix hydrostratigraphic units composed of four aquifers, including a new one (the {D}wyka), and two aquitards were identified. {A}nalysis of the regional groundwater flow system revealed that groundwater flows in two directions, indicating presence of a regional groundwater divide. 3{D} hydrostratigraphic geometry revealed that groundwater flow in {STAS} is influenced by topography but also by faults such as the {Z}oetfontein {F}ault, which displaces the pre-{K}alahari rocks vertically creating a barrier to groundwater flow. {H}ydrostratigraphic and 3{D} geometry work also led to a 42% increase of the size of {STAS} compared to the boundary initially delineated by {UNESCO}. {T}he proposed hydrogeological conceptual model forms a basis for development of numerical integrated hydrological model to simulate surface-groundwater interactions, regional groundwater flow and aquifer development potential.},
