Improvement of waterflows in the National Water Balance.

Water Stocks; feasibility of Water Balances per River basin.

In this project we have tried to compile a full water balance sheet for the year 2009 for the Netherlands. Required methods and data collections have been developed to compile the water balance at the national scale. We have also assessed whether compilation of a regionalized water balance at the levels of the (sub-)River Basin was feasible and whether the required quantifications could be made.
