The central Australian groundwater discharge zone: Evolution of associated calcrete and gypcrete deposits

Abstract Several new techniques were used to identify zones of groundwater and contaminant inflow to the headwaters area of a small stream draining an agricultural watershed in southwestern Ontario. Along a 3 km length of stream, seepage meters were used to measure and collect seepage flux and mini-piezometers were used to measure piezometric head relative to the stream and to collect pore water 0.6 m below the streambed. Measurement of seepage flux at 43 locations along a 3 km segment of Hillman Creek showed that most of the study section was a groundwater discharge zone. Spatial differences in seepage flux ranged from less than 0.001 to nearly 9 cm m s 1. During the growing season there was a marked diurnal change in seepage rate at several locations and this was also reflected by a corresponding change in stream discharge. Paired samples, one from a piezometer 0.6 m below streambed and one from the adjacent seepage meter, were significantly correlated (P < 0.01) with respect to specific conductance, chloride and inorganic carbon concentration. This suggested that in many instances site-specific estimates of chemical inputs from groundwater to surface water can be estimated quickly without the necessity of allowing natural groundwater flow to flush out the water initially trapped within the seepage container. Seepage meters can be used to measure seepage flux and the small piezometers can be used to obtain samples. The concentrations of non-conservative solutes (organic carbon, nitrate + nitrite nitrogen, and phospate) in seepage meter samples were not significantly correlated with the concentrations in corresponding mini-piezometer samples.

Groundwater Basin

Groundwater is the valuable resources for supplying daily necessity of human’s life that is going to increase in line with the increasing number of population. Therefore, groundwater needs to be well managed. Groundwater management can be done thoroughly within a groundwater basin for defining groundwater recharge zone. The groundwater recharge zone was conducted by applying geospatial analysis using weighted and scoring approach. This method was accomplished by overlaying the score of some parameters (hydraulic conductivity, precipitation, soil cover, slope, and groundwater depth of water table) using ArcGIS 10.3 software. The parameters were permeability of rocks, rainfall, soil type, slope and depth of superficial groundwater level. The result of geospatial analysis can be divided into two zones which are groundwater recharge zone and groundwater discharge zone.
