Topography is a dominant factor in hillslope hydrology. TOPMODEL, which uses a topogaphical index derived from a simplified steady state assumption of mass balance and empirical equations of motion over a hillslope, has many advantages in this respect. Its use has been demonstrated in many small basins (catchment areas of the order of 2-500 km(2)) but not in large basins (catchment areas of the order of 10 000-100 000 km(2)). The objective of this paper is to introduce the Block-wise TOPMODEL (BTOP) as all extension of the TOPMODEL concept in a grid based framework for distributed hydrological simulation of large river basins. This extension was made by redefining the topographical index by using an effective contributing area af(a) (0
