Look at the p.65 of this document. They reveal some information regarding the mapping of the assets and liabilities. Based on this mapping, you could perform gap analysis and see if you have any deficit in a given maturity slot and then hedge accordingly.
Joel Bessis' books on Banking Risk Management may also be useful.
UPDATE: Alright, here is the approach that is used:
$V(T) = V_0 e^{(-q \sigma \sqrt{T - 0.5 T \sigma^2})}$
$V_0$ - clients' account balances today (or on calculation date)
$T$ - periods of mapping (could be 3M, 6M, 9M, 1Y, etc.)
$q$ - quantile (95%, 99%, etc.)
$\sigma$ - volatility of the clients' account balances over a time period (12M, 24M, 36M)
Basically, the account balance follows GBM with chosen confidence level $q$.
