Method for creating a structure of a topology of a defined bounded surface for dewatering said surface by means of at least one predetermined drainage point , so that the surface comprises a monotonically increasing inclination starting from the drainage point up to a collision point , wherein the topology is determined by computer-implemented method steps by dividing the surface into individual surface elements each having at least one plane , and for each surface element , starting from the drainage point , an inclination in a first direction and/or a second direction perpendicular to the first direction is successively determined in each plane in order to form the surface starting from the drainage point up to the collision point with the monotonically increasing inclination, wherein for at least one surface element directly adjacent to the drainage point a fillet slope is determined by dividing the respective surface element into at least two planes and crossing the associated surface normals, wherein the computer-implemented method steps are carried out to generate, for the surface , an allocation plan for representing the individual surface elements with the specified inclinations, wherein the allocation plan is stored on a data carrier, wherein the layout plan is generated as a guide for creating the structure of the topology according to the specified inclinations, wherein the layout plan for the individual surface elements comprises at least one dimension and one geometric shape, respectively, and wherein the structure of the topology is created according to the occupancy plan by occupying the area by a plurality of panels whose dimension and geometric shape are adapted according to the individual area elements of the occupancy plan. wherein the topology is determined by computer-implemented method steps by dividing the surface into individual surface elements each having at least one plane , and for each surface element , starting from the drainage point , an inclination in a first direction and/or a second direction perpendicular to the first direction is successively determined in each plane in order to form the surface starting from the drainage point up to the collision point with the monotonically increasing inclination, wherein for at least one surface element directly adjacent to the drainage point a fillet slope is determined by dividing the respective surface element into at least two planes and crossing the associated surface normals, wherein the computer-implemented method steps are carried out to generate, for the surface , an allocation plan for representing the individual surface elements with the specified inclinations, wherein the allocation plan is stored on a data carrier, wherein the layout plan is generated as a guide for creating the structure of the topology according to the specified inclinations, wherein the layout plan for the individual surface elements comprises at least one dimension and one geometric shape, respectively, and wherein the structure of the topology is created according to the occupancy plan by occupying the area by a plurality of panels whose dimension and geometric shape are adapted according to the individual area elements of the occupancy plan. <EOS>
