As climate change infiltrate and influence every sphere of the globe, the continuous study of the drainage features and assessment of the drainage basin as a fundamental geomorphic unit in water resources development and management cannot be relegated. This work has considered the analytical description of the physical division of RDCA. The three domains of the morphometric parameters (linear, areal, and relief aspects of the basin) were considered for the analysis.  Remote sensing and GIS techniques were adopted in the analysis of the data using hydrological and surface tool in ArcGIS 10.2. The acquired SRTM DEM was used to delineate the catchment area and major morphometric parameters were estimated. The results show that the basin is elongated with low leminiscate ratio. RDCA is a 7th order drainage basin, with an area of 11,355 km2, having a length of about 164 km2. Value of drainage density indicates moderate runoff potentials. Stream frequency, bifurcation ratio and constant channel maintenance indicate medium permeability and that the basin produces a flatter peak of direct runoff for a longer duration. Channel encroachment, land use and land cover change seems the cause of perennial flooding in the region than change in drainage features. This study provides scientific database for further comprehensive hydrological investigation of RDCA around which Kashimbilla dam is located.

In the present paper an attempt is made to study the morphometric characteristics of five watersheds which are part of Seybouse and Coastal basin of Constantine located in northeast of Algeria. The study focuses on evaluating the effect of morphometric parameters on land degradation. The Geographical Information Systems which represent efficient tools in determination of drainage basin morphometric properties and principal component analysis are applied to ten geomorphic parameters on twenty subwatersheds, to group the parameters under different components based on significant correlations. Some morphometric parameters are computed and analyzed such as basin area, drainage density, stream frequency, form factor, orographic coefficient, hypsometric integral, and lithology index, basin slope, average overland flow distance, basin relief ratio. Outcomes of the matrix of correlation and principal component analysis of ten geomorphic parameters clearly depict that fifty percent of the variables are strongly correlated with the components like basin area, drainage density, stream frequency, orographic coefficient and relief ratio. It has been found that Guis sub-basin, three sub-basins of the Saf Saf watershed and all the sub-basins of the Mellah watershed are subjected to high land degradation, thus, creating an urgent need for applying soil and water conservation measures.

The area of investigation lies between Maneri and Gangnani along the Bhagirathi river in the lesser and central Himalayan block of Garhwal Himalayas. The rocks of Garhwal group are represented by quartzites, sericite quartzite’s and talc chlorite schist intruded by metabasics, whereas the Central crystallines are constituted by gneisses, schists, migmatites and amphibolites. For the purpose of drainage basin morphometric analysis 100 third order drainage basins were marked. Drainage basin morphometric parameters of 100 basins were calculated. On the basis of lithology and tectonic setup,the area was divided into three morphogenetic units viz Central crystallines, Thrust zone and Garhwal group. The basins which were situated below 2500 mts are categorized under low altitudes and above 2500 as basins of higher altitudes.The relationship between deainage basinmorphometric parameters and altitude suggest that basins situated at higher altitude have higher value of stream frequency, number of first and second order streams,fine texture and low drainage density.

The morphometric analysis of any drainage basin is considered useful for water resource studies such as flood assessment, water quality sampling, water use reporting, watershed management etc. Drainage basin is generally defined as the areal extent of land from which the surface runoff flows to a defined drain, channel, stream or river. It is mainly governed by the topography of the terrain. Geographical Information System and Image Processing Techniques can be used for the identification of morphological features and analyzing properties of the basin. The morphometric parameters include linear, areal and relief aspects. ‘Watershed Atlas of India’ (2014) on 1:50,000 scale is an important digital database for planning and monitoring of development programs on a watershed basis. It serves as a uniform baseline for developing a hydrological unit-based data bank to be used for the management of water resources in the country. Run-off, sedimentation, water balance, evapotranspiration and several other catchment characterization related studies may be taken up on a watershed basis. The present study deals with morphometric parameters such as stream order (Nu), stream length (Lu), bifurcation ratio (Rb), drainage density (D) and stream frequency (Fs) of the Betwa drainage basin. Geographically the basin (77° 30′ to 80° 12′ east longitudes and 23°30′ to 25°55′ north latitudes) is located in two states i.e. Madhya Pradesh and Uttar Pradesh occupying an area of 43780 km2. The length of the stream segment is maximum for the first-order stream and decreases as the stream order increases. This study would help in understanding the hydrological behaviour of the basin. This, in turn, may enable the local people to utilize the resources of the basin for the sustainable development of the area.

Drainage Texture

Slope movement processes along with other terrain attributes influence surface morphology of an area. Correlation analysis of nineteen morphometric parameters and the landslide areal extent in 26 third order basins in a part of Garhwal region of the Lesser Himalaya, U.P. India, indicates that fraction of landslide area (Ls) in a basin has statistically significant correlation coefficient of about 0.86, 0.84, 0.68 and -0.55 (at 99% confidence level) with drainage texture (DT), stream frequency (SF), drainage density (DD) and basin circularity (BC) respectively. Drainage texture which is the product of stream frequency and drainage density, is one single morphometric parameter in a basin that has in it, the influence of many morphometric parameters which in turn, are reflection of the cumulative effect of elevation, slope, lithology, structural features, vegetation and hydrological condition. Higher the drainage texture, higher is the landslide areal extent. Based on regression analysis, a relationship between fraction of landslide area (Ls) and drainage texture (DT) of third order basin has been worked out which suggests that the third order basins always have some unstable slope faces. With a drainage texture of about 185, almost all the slopes are expected to be unstable. Relatively stable areas are associated with lower values of drainage texture. Circular basins with low relief have lower values of DT and therefore, their slopes are relatively more stable. This identified relationship is found to be useful within the error limit of 25 percent and is, therefore, recommended for use as a first step towards the landslide hazard zonation in similar terrains.

Drainage Texture

This study evaluated some morphometric parameters with a view to assessing the infiltration potential of Osun Drainage Basin (ODB), Southwestern Nigeria. Input data were derived from SPOT DEM using ArcGIS 10.3 platform. ODB has an area extent of 2,208.18 km2, and is drained by 1,560 streams with total length of 2,487.7 km. The Relief Ratio (5.6) suggests that ODB is characterized by topographic high and topographic low. Thus, infiltration potential would be low as surface runoff would have less time to infiltrate before entering the drainage channels. The computed values of Drainage Texture (0.52), Stream Number (1,560), Total Stream Length (2,487.7 m) and Main Stream Length (119 m) indicate that larger percentage of annual rainwater would leave ODB as river discharge. Stream Frequency, Basin Perimeter, Length of Overland Flow and Drainage Density influence Infiltration Number across the basin. Infiltration Number increases with increasing Stream Frequency (r = 0.95) and Drainage Density (r = 0.78); and Length of Overland Flow increases with decreasing Drainage Density (r = -0.83), Stream Frequency (r = -0.51) and Infiltration Number (r = -0.45). The study concluded that basin’s infiltration potential is moderate as suggested by the mean Infiltration Number.

Channel plan-form patterns of river Tlawng has been studied which shows that there is variation in the sinuosity index. This variation is a sign of changing characteristics and behavior of the river. The average sinuosity of the river is 1.41. The sinuosity index is higher in the lower course of the river as it flows through alluvial plain. GIS techniques have been used for studying morphometric parameters. There are 6736 streams in the Tlawng river basin which shows that the topography is still undergoing erosion as the number of stream is high (Zaidi, 2011). The river has low bifurcation ratio which indicates less possibilities of flooding. The drainage density indicates the higher permeable subsoil and moderate to thick vegetative cover. The stream frequency value of the Tlawng river basin is 1.30 streams / km2 which shows a positive relation with drainage density.

This study attempts to study the morphometric characteristics of the Ghatganga basin by using Geographical information system (GIS). This analysis has shown that the relation of stream order (U) and stream number (Nu) which gives a negative linear pattern that order increases with a decreasing number of stream segment of a particular order. Different morphometric parameters such as stream length (Lu), bifurcation ratio (Rb), drainage density (D), stream frequency (Fs), texture ratio (T), elongation ratio (Re), circularity ratio (Rc), form factor ratio (Rf), relief ratio (Rh) and river profile have revealed the basin has a dendritic pattern of drainage, indicating high relief and steep ground slope with less elongated young and mature landforms in which geological structures don’t have a dominant influence on the basin.

In watershed hydrology, the morphometric features of a river basin are vital to examine the lower Orashi River basin morphological and hydrological aspects, as well as its flood potential, based on their morphometric characteristics using remotely sensed SRTM data that was analyzed with ArcGIS software. The areal, linear, and relief aspects of the Orashi River basin were examined as morphometric parameters. The lower Orashi river basin, according to the findings, has a total size of 625.61 km2 and a perimeter of 307.98 km, with a 5th order river network based on Strahler categorization and a dendritic drainage pattern. Because of low drainage density, the drainage texture is very fine, the relief is low, and the slope is very low. Bifurcation ratio, circularity ratio, drainage density aspect ratio, form factor, and stream frequency values indicate that the basin is less elongated and would produce surface runoff for a longer period, while topographic changes show that the river is decreasing with depth in the land area at about the same elevation as a result of sand deposited due to lack of maintenance by dredging, which implies that the basin is morphometrically elevated and sensitive to erosion and flooding. To understand geohydrological features and to plan and manage watersheds, morphometric analysis based on geographic information systems and remote sensing techniques is beneficial.

The study area includes the catchments of Selemnos, Xylokeras and Volinaios torrents, with 456 streams of 277.848 km total length. The pattern is generally dendritic. A quantitative analysis of the drainage systems of the study area was interpreted and then correlated to the fault systems that appear in the area. The main direction of the streams and the tectonic features is WSW-ENE. The drainage density and stream frequency is highly variable as a result of many factors, most important of which is lithology with high infiltration capacity. The number and the length of most streams show divergence of the 1st and 2nd law of Horton since they have dissimilar values from those theoretically expected.
