Abstract
VAN TOL, JJ and BOUWER, D. Hydropedology of South African soil forms and families. Water SA [online]. 2024, vol.50, n.2, pp.236-245. ISSN 1816-7950. http://dx.doi.org/10.17159/wsa/2024.v50.i2.4094.
Hydropedology is an interdisciplinary field that studies the interactions between soil and water, recognizing that soils influence hydrological processes through their hydraulic properties, and serve as indicators of hydrological behaviour through their morphological properties that are shaped by water regimes. Given the practical implications of hydropedology and its integration into South Africa's latest soil classification system, an updated categorization of soil forms and 1 657 (1 629 + 28) families was necessary, organizing them into three overarching response groups based on their predominant hydrological responses: recharge, interflow, and responsive. Within these groups, recharge soils are further classified into deep, shallow, and slow subgroups, interflow soils encompass soil/bedrock, shallow, and slow categories, while responsive soils are subdivided into responsive shallow and responsive wet. This paper aims to enhance the reader's comprehension of hydrological responses and simplify the intricacies integrated into South Africa's official soil classification system.
Keywords : catchment hydrology; hydrological modelling; lateral flow; recharge; soil water balance; wetland soils.
