Leanne, surface water gw interaction lecutre 1 Flashcards
draw gaining and losing stream contours
ok
example of a losing and gainng steam
selwyn
name the different types of streams and their properties
perennial- all year round
intermittent - seasonal
ephemeral - only during floods
two types of losing streams
connected, unconnected
draw what a small and large flood looks like for river bank recharge
ok
draw impact of pumping on stream deplection, two cases
ok
two categories of stream depletion.
direct field-based methods
indirect field-based methods
draw two types of field based methods
hammer and shell one,
and drum one
what are four indirect field base methods
use temperature relationship
use a mass balance
use that hardcore equation
use hydro graph separation
the river murray, draw and explain attributed during high and low flow
low flow- small fresh water lense on top of saline water
uncofined
groundwater drains to river
high flow-becomes confined
bank storage and lense size increases
mobilisation of salts
3 things impacting the river murray and how
weirs and locks-rise river and GW levels, more ET and salinisation
irrigation abstraction- lower flows, smaller floods
irrigation recharge, mounding, push salts to flood plain
remediation techniques
SIS pumping, reduce salt flux
environmental regulations
what numerical modeeling program
