Capital Cost Minimization of Drainage Networks

Journal of the Environmental Engineering Division, 1974
This paper presents and compares three mathematical programming models for the optimization of drainage networks. The three models are based on two extensions of linear programming: separable-convex and mixed- integer programming. The first produces a continuous range of diameters while the second limits the solution to discrete commercially available ...

Automatic Measurement of Drainage Networks

IEEE Transactions on Geoscience Electronics, 1970
Two methods for measuring network lengths and areas by automatic methods are discussed. Results of experiments using drainage networks are presented and indicate that further study and refinement are warranted. The first method involves etching the network on a copper plate and measuring its capacitance.

Optimal design of urban drainage networks

Civil Engineering and Environmental Systems, 2013
In this paper, a general procedure for the optimal design of urban drainage networks is proposed taking into account realistic technical constraints and the management cost of the automatic flushing devices. The procedure, which is based on the utilisation of a standard genetic algorithm, is first tested with reference to a urban drainage network taken

Junction angles in drainage networks

Journal of Geophysical Research: Solid Earth, 1984
The systematics of tributary junction angles are an important link between the topology of a drainage network and its topography because the angle of junction depends on the relative slopes of the intersecting tributaries. I present here a model for stream junction angle as a function of position (link magnitude)within the network which quantitatively ...

Drainage Network and Topography

2001
Little attention has been paid to the dependence of distributed parameter simulations on the resolution of the raster array or the triangular irregular network (TIN). Further, as these models are calibrated at one resolution, the question remains whether the calibrated parameters may be used without adjustment at larger cell sizes.

Feature-based derivation of drainage networks

International journal of geographical information systems, 1993
Abstract An approach to the automatic derivation of drainage networks from digital elevation models (DEMs) using regular-gridded data is described. Features such as depressions and plateaus, on which drainage directions are undefined, are handled as entities in their own right, and are identified using operations on connected regions.

Resilience-Oriented Coordinated Topology Reconfiguration of Electricity and Drainage Networks With Distributed Mobile Emergency Resources

IEEE Transactions on Smart Grid
This paper proposes a coordinated topology reconfiguration method for power distribution networks (PDNs) and urban drainage networks (UDNs) to facilitate the load restoration and flood prevention with diversified mobile emergency resources (MERs) under ...

Stream Orientation Structures in Drainage Networks

The Journal of Geology, 1976
Stream orientation structures are defined by nonuniform distribution of stream flow directions. Such structures may be analyzed in a regional mode, referring the stream vectors to a common regional base azimuth, and in a network mode, relating the stream vector azimuths to the orientation of the network from which the streams were drawn.
