Transpiration and water relations of evergreen shrub species on an artificial landform for mine waste storage versus an adjacent natural site in semi‐arid Western Australia

In water-limited environments, transpiration may minimize deep drainage on engineered covers used for hazardous waste disposal. However, comparative studies investigating plant ecophysiology and water use on engineered covers and natural sites are limited. Water use patterns and plant-water relations of evergreen shrubs were monitored in semi-arid Western Australia to (1) investigate the response of plant-water relations and shrub transpiration to soil moisture changes and (2) quantify stand transpiration and its contribution to the water balance. The shrubs showed conservative (<20 cm hr À1) but persistent transpiration. Differential response to rainfall pulses was evident among species; sap velocity for Acacia bivenosa and Acacia inaequilatera increased by 20-103% (p < 0·05) after rainfall events exceeding 15 mm but declined rapidly to pre-storm levels. On the contrary, sap velocity for Acacia pruinocarpa increased by 61% after large pulse (83 and 127 mm) associated with cyclonic activity and remained high (10-15 cm hr À1 ) thereafter. These transpiration patterns suggested contrasting rooting patterns among the species. Sap velocity was low (<20 mm hr À1 ) for all species, even when moisture was readily available. Annual shrub transpiration was 65 (engineered cover) and 81 mm (natural shrubland), accounting for 16 and 20% of annual rainfall (395 mm). Stand characteristics, plant ecophysiology and shrub transpiration were comparable for both sites, demonstrating the importance of using topsoil as a growth medium and seedbank in revegetation. Overall, the study provided insights on ecophysiological behaviour of artificial landforms, and the first empirical evidence suggesting rapid and successful restoration of mined lands can be achieved under semi-arid conditions.

“…Herczeg (2002, 2005) and Westbrook et al (2005) have used a similar suite of factors to map the distribution of water types and transition zones in the subsurface and the discharge for fresh groundwater towards the sediment/water interface, especially for the upper strata of hyporheic interstices (Brunke & Gonser 1999). E.g., a trend of increasing salinity along the groundwater flow path was demonstrated for catchments in the Western Australian Wheat Belt due to the combination of evaporation and rock dissolution in conjunction with travel time in the aquifer (Salama, Bartle, & Farrington 1994).…”

Gradients in the sediment fauna comprising groundwater (GW) and hyporheic taxa were investigated in the sand/ silt-bottomed Marbling Brook in Western Australia. The structure of sediment invertebrate assemblages from Marbling Brook sediments and the adjacent GW were studied at five sites over 1 year and hydrological interactions were characterized using a suite of abiotic factors. Although all five stream sites were upwelling, the sites differed in the degree of hydrological interactions between GW and surface water. Sediment fauna taxa abundances were not correlated with any of the abiotic factors investigated and did not change gradually with depth. Faunal assemblages in the stream sediments were distinct from faunal assemblages in alluvial GW. While water exchanged between alluvial GW and sediment water, as shown by abiotic factors, the distinct differences in faunal assemblages indicated an unpredicted complexity in the catchment with fundamentally different hydrogeological situations on the decimetre scale. Sampling in sandy sediments needs to take this small-scale variability into account.

“…As a result, only a small number of catchments can be measured fully. To overcome the financial and logistical constraints, Salama (1994a and b) has developed new methods for hydrogeologically characterising catchments at an acceptable level of precision but at much lower cost (less than one-third of the traditional method). The methods are based on using existing spatial data (topography, geology, aerial photography and remote sensing) which are integrated using geographic information systems (GIS) to generate hydrogeological sets of data which classify a catchment into hydrogeomorphic units and determine groundwater levels.…”
