“…A bifurcation ratio between 3 and 5 indicates that although the basin has geological structure, it has little effect on the water system. A bifurcation ratio is less than 3, it indicates that the terrain of the basin is almost flat without any structural influence [47]. A bifurcation ratio greater than 5 indicates that the terrain of the basin is strongly controlled by the local complex geological structure [48].…”

Computer simulations are introduced into the river dynamics field to provide a basis for studying fractal river networks. This paper improved on the defects of particle aggregation and growth methods in the standard diffusion-limited aggregation (DLA) model and proposed a fractal algorithm for simulating the evolution of the river network. To correct these defects, this model used watershed geomorphology as the entry point and analyzed the characteristics of runoff classification, aspect probability and contour lines. Thus, the unit-gradient growth calculation method, anisotropic Brownian motion and other related parameter optimization mechanisms (such as probability-position and step size) were established. In addition, the 2D fractal river network was simulated under different conditions. These simulations calculated the bifurcation ratio of the rendering based on Horton's law, and its value was bounded between the values of natural river channels (3 ~ 5). The standard DLA algorithm was used for simulation, but the bifurcation ratio (±5.2) of the aggregate was higher than the value of the natural river network. Therefore, the improved model can reflect the structural characteristics of the river network more realistically based on quantitative indicators. The evolution mechanism of the natural watershed was evaluated by the cyber-physical systems theory, providing a model base to study the growth and evolution of river networks. The fractal dimension of the water system fitted with each simulated subgraph was based on the box counting method. The value boundary was between 1.457 and 1.747, providing a division standard for the development degree of the watershed geomorphology. Further, according to the relationship between the number of particles and the fractal dimension, the sensitivity test of the model was also analyzed and evaluated, and its sensitivity coefficient gradually increased from 2.75 to 8.38 based on a suitable data-set, which will make the predicted watershed water system closer to its development level. Finally, use of the improved DLA model was suggested for modeling river networks.

“…Usually, it falls between 3.0 to 5.0. The watershed that had undergone less structural disturbance has lower values of Rb (less than 3), and the one that had undergone high structural disturbance has higher Rb values (6,14) . Mean Rb values obtained from toposheet, PALSAR, SRTM, CARTO, and ASTER DEMs are 4.29, 4.25, 4.26, 4.32, and 4.32, respectively (Table 4 ).…”

Objectives:The goal of this research is to calculate, compare and analyze the morphometric drainage parameters of Shiriya River Basin (SRB), Kasaragod, Kerala, using DEMs acquired by different satellite sensors and topographic data (SOI toposheet) for sustainable watershed development. Methods: The Arc GIS 10.3.1 software was used to measure linear, relief, and areal aspects of morphometry. The input data used for deriving the drainage network of the SRB were SOI toposheet (1:50000 scale), SRTM DEM (90m), Cartosat, ASTER and ALOS PALSAR DEM of resolution 30 m each. The relative error percentage of basic parameters derived from DEMs concerning the toposheet is calculated. A groundwater potential map is prepared using weighted overlay analysis of thematic layers (geology, geomorphology, slope, drainage density, lineament density and depth to water level). Findings: Present study revealed that the parameters derived from SRTM DEM data are more similar to those derived from toposheet. Most of the parameters obtained from each input DEM are more or less equal, and the minor variation may be due to varied data collecting and processing methodologies used for DEM creation. SRB is characterized by 6 th order stream with a dendritic drainage pattern, which is elongated and less susceptible to soil erosion. SRB has an intermediate texture and is in a mature stage of geomorphic evolution. Inference from the ground water potential zonation map indicates that major portion of the SRB has moderate ground water potential. Application/improvement: The study would be a valuable source for identifying water recharge sites, basin modelling, and groundwater prospect mapping. Novelty:This research has attempted to compare and analyze the morphometric parameters' results from multisensor satellite data for sustainable watershed management. An attempt has been done to understand the relation between morphometric parameters and ground water potential of SRB using Groundwater potential zonation map.

“…According to the table (2), the Rn values for sub-basins ranged from 0.01 to 1.28. Due to their channel gradient, peak discharge, and dissection, high-roughness sub-basins have a potential of flooding (Singh et al, 2020).…”

Watershed management is critical to sustainable development. The topographical, and hydrogeomorphological conditions in the western part of the Luxor region give rise to sudden floods. The purpose of the present study is to map the flood hazard zones in the western part of Luxor by using: 1-linear Watershed Index Model (LWIM) through the identification of 24 morphometric parameters; 2-DEM, as input to the GIS environment, using the Arc hydro-Tool; 3-Remote sensing (RS), is built into GIS to detect LU /LC via supervised classification of Landsat images, for the year 1991/2021, and Dreanig density (Dd) maps; 4-Integration of LWIM, Dd, and LU/LC maps. Results indicated that agricultural land increased by approximately (292.7 km 2 ), while urbanization increased by (43 km 2 ) between 1991 and 2021, expanding toward the western structure plateau. This study concluded that flood areas west of Luxor are confined to the desert area west of cities Luxor -Arment, and Isna. These areas represent 13.25 % of the hazard flooding zones. The study proposed to establish small dams with diversion channels in the way of the mainstream channels with high orders 4 th and directed the water of flood to new canals which joined with the main canals in the study area, re-design of the desert zone west of Luxor.
