The Vu Gia - Thu Bon river basin is one of the largest basins in Vietnam. Research and assessment of this potential basin is a great interest to scientists and regulators. One of the important studies is the evaluation of morphological parameters of the basin. The morphological parameters represent water resources and at the same time are one of the factors that help researchers give a comprehensive view of the basin, assessing the factors related to the direction of the flow, the flow rate or hazards throughout the basin. Therefore, this paper is an attempt to evaluate the morphology of Vu Gia - Thu Bon river basin using DEM SRTM (30 m) data in GIS. This analysis can be achieved through the measurement of linear aspects, aerial aspects and relief aspects of the drainage basin. The results of the study show that stream order ranges from first to sixth order with a total stream length of 1024, a total length of 3183.2 km. Basin was divided into three subregions: upland, midland, and lowland. Those represent 66,9%, 26,0% and 7,1% percent of the region’s total area respectively.

Hydrological analysis and for the integrated development of the watershed, it is essential to do geomorphometric analysis. A comprehensive study of drainage pattern, topography, and most essential erosion status can be analyzed through morphometric analysis. Prioritization of sub-watersheds according to the capacity of the water table of Nashik district watershed was evaluated by linear, aerial and relief aspects. The morphometric analysis has been used for the prioritization of seven sub-watersheds of the Godavari river basin in the Nashik district, Maharashtra. Using the Digital Elevation Model, the sub-watersheds were delineated in ArcMap 10.4 and also few extraction works were done in Erdas Imagine. Drains and their corresponding characteristics including stream length, stream order, stream frequency, circulatory ratio, texture ratio, compactness coefficient, elongation ratio, form factor, drainage density, bifurcation ratio is analyzed and their value has evaluated for each sub-watershed by using the Remotely Sensed-data and geospatial techniques. Finally based on morphometric behavior the priority has been given to each sub-watershed & rank has assigned to them, the most sensitive sub-watershed is identified. The reveled analysis says stream order ranges from 1 to 6. The overall stream segments of all order are 1,115 in the watershed. On the account of morphometric analysis prioritization of watershed is done. Resulting prioritization rank assigned to each watershed based upon the evaluated compound parameter given to them. Those Sub-watersheds having least compound parameter value has assigned the highest priority. Further, sub watersheds accordingly categorized into three type i.e. high (3.4-3.8), medium (4.0-4.2) and low (4.4) priority based on their maximum priority score (4.5) and minimum score (3.4).

Aims: The paper aims to study about the river basin morphometry namely the physical, linear and aerial parameters for the basin. Study Design: The Study has been carried out with the help of Geospatial techniques and statistical formulas. Place and Duration of Study: Bharathapuzha river basin, Kerala, India between January 2018 to July 2018. Methodology: The Study of River morphometry of Bharathapuzha River basin has been done with the help of SRTM satellite data. The downloaded data has been analyzed with the help of ARC GIS Software. The morphometric analysis has been carried out by dividing the basin into nine watersheds based on Water shed Atlas of India Prepared by Soil and Land Use board of           India. Relief, Linear and areal parameters of the basin is calculated with the help of statistical formulas. Results: Based on the analysis it is noted that there is not much difference in morphometric values except in some watersheds. Watershed number 5A2B5, 5A2B6 and 5A2B7 has highest drainage density, stream frequency, relief, relief ratio, ruggedness number, stream length ratio and lowest bifurcation ratio. These watersheds are characterized by highest surface runoff and erosion. The values of form factor, circulatory ratio and elongation ratio suggests that most of the watersheds are elongated and has high basin relief. The maximum stream order frequency is observed in case of first order streams and then for second order streams. Hence it is noted that there is decrease in stream frequency as stream order increases. Conclusion: The mean bifurcation ratio of the Bharathapuza basin is 1.52 which indicates the whole basin is less effected by structural control. This present study is valuable for the erosion control, watershed management, land and water resource planning and future prospective related to runoff study.

The article studies one of the basic definitions of International Water Law – “transboundary waters”. It is noted the altered priorities of the use of water resources as well as new methods used in the natural sciences, especially in the hydrology, have an impact on the content of this definition. It is investigated the correlation of such definitions as “transboundary waters”, “transboundary watercourses”, “international watercourses”, “international river basin”, “international drainage basin”, “international rivers”, “international lakes”. It is analyzed sources of international water law, which was elaborated terminology and definitions, it is traced their evolution. The author points out the following features of the definition “transboundary waters”: 1) these include surface water and groundwater; 2) they cross the border between two or more states are located on boundaries; 3) the use of transboundary waters affects the interests of two or more states; 4) the special legal regulation of their use (the doctrine of absolute sovereignty over water resources are located within of boundaries of the state; the doctrine of belonging of transboundary waters to all states of the international drainage basin; the doctrine of optimal development of the river basin; the doctrine of limited sovereignty; the doctrine of the priority); 5) specific requirements for the protection of ecosystems of transboundary waters; 6) the large conflict potential in use of water resources.

Aims: Morphometric study of Dhatarwadi river basin. Place and Duration of Study: This study is a work done for the research work in Ph.D. degree at College of Agricultural Engineering and Technology, Junagadh Agricultural University, Junagadh, Gujarat, India. Methodology: Morphometric analysis involved determination of linear, aerial and relief aspects of the Dhatarwadi river basin, which was carried out using 30 X 30 m SRTM DEM in ArcGIS 10.5 software using standard formulae. Results: The obtained results revealed that the Dhatarwadi river basin is 6th order drainage basin. The total number of 1327 streams were identified out of which 1st, 2nd, 3rd, 4th, 5th and 6th order streams are counted as 1036, 239, 42, 7, 2 and 1 number, respectively. The mean bifurcation ratio value is 4.31 for the study area which indicates that the geological structures are not distorting the drainage pattern. Stream length ratio varies between 0.14 and 2.14 indicates late youth geomorphic stage. The length of overland flow was found as 0.3084 km which also indicates very less structural disturbance, low runoff conditions and having higher overland flow. The stream frequency of the basin is 1.5448 km-2, indicates that this basin is having high permeable geology, low relief and the almost flat topography. The form factor, elongation ratio, circularity ratio and compactness coefficient are found as 0.3951, 0.7094, 0.3126 and 1.7882, respectively of the study basin is suggests that the Dhatarwadi river basin shape is elongated. The drainage texture is 7.1426 km-1 which shows that the Dhatarwadi river basin has short duration for peak flow. The relief, relief ratio and relative ratio of the basin are found as 0.438 km, 0.009372 and 0.2352, respectively. Conclusion: All these parameters indicate that the Dhatarwadi river basin is of flat terrain with small hillocks/inselbergs having low to medium runoff potential.

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.

Rainwater Runoff

Basin morphometry is a crucial method of analysis to understand the geology, lithological structure, infiltration rate of rainwater, runoff, eroded load carrying capacity and flooding potential of a drainage basin. The quantitative techniques applied for linear, aerial and relief aspects of the drainage basin elucidate the rate of erosion, the intensity of denudation and subsequently the potential of the Nandakini river basin to flooding. The morphometric analysis of the Nandakini river basin in the Garwhal Himalayan region of Uttarakhand reveals that the Rf value of the Nandakini river basin is 0.28, indicating an elongated basin shape leading to quick flooding and poor draining out of floodwaters. Similarly, an elevation difference between the highest and lowest elevation is 5380 metres aids quick runoff and deposition of eroded debris in the drainage channels, another cause of channel overflow. The Rh value is high (0.12), indicating a high channel gradient with intense erosional processes operating due to steep gradient and this has a considerable impact on the rate of erosive geomorphic processes operating. The higher elevation on the Eastern part of the basin due to the Vaikrita Thrust, the Munsiyari Thrust (ie. the southern tilting Main Central Thrust) and the Baijnath Klippe has resulted in metamorphism in Miocene and Pliocene explaining the low rate of infiltration and rapid runoff.

The Impact

Management of water resources required assessment of morphometric parameters in order to enhance the capability of understanding the factor which may help to render the impact caused due to high flood due to inadequate water disposal management. In the present study computation of linear, aerial and relief aspects viz., bifurcation ratio, mean bifurcation ratio (Rbm), mean stream length (Lum), stream length ratio (Rl), form factor (Ff), circularity ratio (Rc), stream frequency (Fs), drainage density (Dd), dissection index (Di), ruggedness index (Ri) has been carried out in order evaluate watershed characteristics for soil conservation and watershed management. The basin poses a high flood potential risk due to inadequate drainage and less channel development. The Ken river basin is elongated in shape as indicated by the computation of form factor with comparatively less value. Due to inadequate drainage patterns for safe disposal of surplus water, the vulnerability to water erosion can be considered as a major cause of concern in the Ken river basin. Evaluation of relief aspects suggested the existence of intense flood characteristics within the basin during period of heavy rainfall. Assessment using remote sensing and GIS approach can prove as an effective tool for analyzing properties of basin and for sustainable management of available water resources with exercise of suitable sites selection for development of structure to control runoff and adaptation of conventional methods for water conservation, thus increasing infiltration rate with decreased surface runoff and erosion.
