Table 1: Results from exploration of effects of simulating CRIMs in combination on downstream peak flow (just upstream of Uckfield; based on 2000 flood event). Initial peak flow simulated for the 2000 event (no interventions) was 124.68 cumecs (2 d. p.). The ‘individual effect on peak flow’ is the effect on downstream peak flow of increasing roughness in that single reach. The ‘effect in combination’ is the simulated peak flow downstream as a result of the number of CRIMs added (shown in the final column).
