relation between the structure of river networks and the features of their geomorphologic hydrologic response. A mathematical formulation of connectivity of a drainage network is proposed to relate contributing areas and the network geometry. In view of the connectivity conjecture, Horton's bifurcation ratio RB tends, for high values of Strahler's order ft of the basin, to the area ratio RA, and Horton\"s length ratio R oe equals, in the limit, the single-order contributing area ratio R a . The relevance of'•these argu•ments is examined by reference to data from real basins.","publication_date":"1991,,","publication_name":"Water Resources

Five fractal dimensions are recognized for stream networks, namely, topological dimension (dt), minimum path dimension (dm), fractal dimension of stream networks as a whole (df), diffusion dimension (dw), and spectral dimension (ds). Mathematical definitions and derivations of the fractal dimensions are proposed, which provide a theoretical basis for some recognized empirical relationships in drainage basin geomorphology. Relationships among the fractal dimensions are examined, and the average values of the fractal dimensions for natural stream networks are estimated. The hydrological implications of the fractal dimensions of stream networks are also discussed.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;wsj-grid-card-download-pdf-modal&quot;,&quot;work_title&quot;:&quot;Fractal structure and properties of stream networks&quot;,&quot;attachmentId&quot;:46160481,&quot;attachmentType&quot;:&quot;pdf&quot;,&quot;work_url&quot;:&quot;https://www.academia.edu/12469612/Fractal_structure_and_properties_of_stream_networks&quot;,&quot;alternativeTracking&quot;:true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/12469612/Fractal_structure_and_properties_of_stream_networks"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="8" data-entity-id="29191339" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/29191339/Fractal_relation_of_mainstream_length_to_catchment_area_in_river_networks">Fractal relation of mainstream length to catchment area in river networks</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="55096585" href="https://independent.academia.edu/BaldassareBacchi">Baldassare Bacchi</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Water Resources Research, 1991</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;wsj-grid-card-download-pdf-modal&quot;,&quot;work_title&quot;:&quot;Fractal relation of mainstream length to catchment area in river networks&quot;,&quot;attachmentId&quot;:49639982,&quot;attachmentType&quot;:&quot;pdf&quot;,&quot;work_url&quot;:&quot;https://www.academia.edu/29191339/Fractal_relation_of_mainstream_length_to_catchment_area_in_river_networks&quot;,&quot;alternativeTracking&quot;:true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/29191339/Fractal_relation_of_mainstream_length_to_catchment_area_in_river_networks"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="9" data-entity-id="13145263" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/13145263/Geometry_of_river_networks_I_Scaling_fluctuations_and_deviations">Geometry of river networks.

Branching networks are a universal structure employed in the distribution and collection of material. Large-scale river networks mark an important class of two-dimensional branching networks, being not only of intrinsic interest but also a pervasive natural phenomenon. In the description of river network structure, scaling laws are uniformly observed. Reported values of scaling exponents vary, suggesting that no unique set of scaling exponents exists. To improve this current understanding of scaling in river networks and to provide a fuller description of branching network structure, here we report a theoretical and empirical study of fluctuations about and deviations from scaling. We examine data for continent-scale river networks such as the Mississippi and the Amazon and draw inspiration from a simple model of directed, random networks. We center our investigations on the sc...</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;wsj-grid-card-download-pdf-modal&quot;,&quot;work_title&quot;:&quot;Geometry of river networks.
