INTRODUCTION

Four different files are included as auxiliary material for Paper #2013WR013591RR, Two figures (Figure S1 and Figure S2) with format .png and two tables (Table S1 and Table S2) with format.docx. 
The figures are meant to complement the results of the research, and the tables present the full chemistry analysis for major ions and environmental tracers of surface 
water and groundwater samples.

List of auxiliary materials:

Figure S1

(a) Tributaries and groundwater contribution to the Mitchell River flow. Shown also measured flows of the Mitchell River at different gauging locations and its tributaries; 
(b) Average tracer discharge contribution from tributaries and groundwater to the total tracer discharge of Mitchell River.

Figure S2

(a) Sum of cations (Na+, Ca2+, K+, Mg2+) vs. sum of anions (Cl-, SO42-, HCO3-) showing charge balance of the resulting modeled groundwater discharge chemistry; 
(b) Relationship between modeled groundwater electrical conductivity (EC) and sum of cations.

Table S1

Environmental tracers results of October 2011 for the Mitchell River, its upper and low catchment tributaries and groundwater. *Tributary sampled far upstream of the confluence 
with the Mitchell River (sampled at the confluence otherwise).

Table S2

Major ions results of October 2011 for the Mitchell River, its upper and low catchment tributaries and groundwater. *Tributary sampled far upstream of the confluence with the Mitchell River 
(sampled at the confluence otherwise).
