It is evident that most of the geomorphic work in seasonal tropics is accomplished by individual flood events. Studies on some large Indian rivers indicate that the channel forms and processes are related to very large but relatively infrequent flood events (Goswami DC, Water Resour Res 21:959–978, 1985; Kale VS, Ely LL, Enzel Y, Baker VR, Geomorph...

Climate change can have an influence on rainfall that significantly affects the magnitude frequency of floods and droughts. Therefore, the analysis of the spatiotemporal distribution, variability , and trends of rainfall over the Mahi Basin in India is an important objective of the present work. Accordingly, a serial autocorrelation, coefficient of...

The September 1973 flood in the Mahi Basin was one of the most catastrophic and widespread in the 20th century. However, the hydro-meteorological characteristics of the 1973 flood were not studied. Therefore, an attempt has been made to analyze the meteorological and hydrological processes that led to the 1973 flood. Accordingly, daily rainfall dat...

Chute channels in rivers flowing on bedrock are uncommon and shaped under limited range of fluvial conditions. This study presents a mechanism of initiation and further development of a chute canyon in the Deccan Trap bedrock along the course of River Par in western India. Based on field evidences, OSL dating, hydraulics and resistivity of the dyke...

Flood Frequency Analysis (FFA) method was introduced by Fuller in 1914 to understand the magnitude and frequency of floods. The present study is carried out using the two most widely accepted probability distributions for FFA in the world namely, Gumbel Extreme Value type I (GEVI) and Log Pearson type III (LP-III). The Kolmogorov-Smirnov (KS) and A...

An attempt has been made in this paper to find out at-a-station hydraulic geometry of the Tapi River. Data regarding hydraulic variables associated with Annual Maximum Series (AMS) are available for four sites on the Tapi River. Moreover, data of hydraulic variables are available for a large magnitude 2006 flood for a site. The data have been used...

The concept of magnitude–frequency was introduced by Fuller, and since then, it has been widely used, especially in Europe and Asia. Over the past, 9–11 decades, several probability distribution models have been developed and applied. The principal objective of the present study is to identify the best-fit magnitude–frequency model at various sites...

The objective of present work is to understand flood hydrometeorological situations associated with monsoon floods on the Par River, therefore, the analyses of synoptic conditions connected with large floods was carried out. This encompasses analysis of interannual rainfall variability and associated floods, analysis of storm tracts, investigation...

Slot canyons, with extremely small width–depth ratios, are rare geomorphic features that develop under limited range of fluvial conditions. We report the occurrence of such an uncommon canyon, developed on the crest of the Western Ghats in the Deccan Traps. The canyon is a tourist hotspot. Geomorphic studies reveal that the Sandan slot canyon is 2–...

Slot canyons, with extremely small width-depth ratios, are rare geomorphic features and develop under limited range of fluvial conditions. We report the occurrence of such an uncommon canyon, developed on the crest of Western Ghat in Deccan Traps. The canyon is a tourist hotspot. Geomorphic investigations reveal that the Sandan Slot Canyon (2-30 m...

Flood frequency analysis is one of the techniques of examination of peak stream flow frequency and magnitude in the field of flood hydrology, flood geomorphology and hydraulic engineering. In the present study, Log Pearson Type III (LP-III) probability distribution has applied for flood series data of four sites on the Mahi River namely Mataji, Pad...

Abstract Flood frequency analysis is one of the techniques of examination of peak stream flow frequency and magnitude in the field of flood hydrology, flood geomorphology and hydraulic engineering. In the present study, Log Pearson Type III (LP-III) probability distribution has applied for flood series data of four sites on the Mahi River namely Ma...

A prime question of rainfall studies in India is whether the monsoon rainfall has changed over the last few decades and whether a change is probably to occur in future. Nonetheless, it is difficult to identify the probable future trend of rainfall, it is possible to detect the nature of changes that have occurred in the past.The Non-parametric Mann...

An evaluation of the effectiveness of flows depends on the magnitude and frequency of the events than mean discharges. Magnitude-frequency analysis is one method that identifies the hydrological and geomorphological importance of these events quantitatively, particularly the frequency of flood events of various magnitudes. Therefore, an attempt has...

Hydraulic geometry is of fundamental importance in flood hydrology and geomorphology. It refers to the rate of change of hydraulic variables, namely width, mean depth, and mean velocity, as discharge increases. An attempt has been made to find out at-a-station hydraulic geometry of the Mahi River with special reference to Annual Maximum Series (AMS...

This paper examines the long term fluctuations and global teleconnections in the monsoonal rainfall and associated floods of the Mahi Basin from western India. In order to analyze rainfall and associated floods, the rainfall data for monsoon season of the Mahi Basin have been obtained for last 149 years (1857-2005) from India Meteorological Departm...

The geomorphic effectiveness of floods is evaluated in terms of stream power () and boundary shear stress () for floods on the Par River. The highest values for  and  for a flood on the river are 52125 W/m2 and 3320 N/m2 respectively. The estimated Froude numbers are <1 indicating subcritical flows. It is >1 for a few constricted reaches showin...

Study of suspended sediment transport in the river basin is of great significance in the fluvial and flood geomorphology. The magnitude and frequency of a flood plays pivotal role in the transportation of the sediment. The concentration of suspended sediment and amount of suspended sediment load in the river basin depends on the geomorphological, h...

A meander, in general, is a bend in a sinuous watercourse or river. A meander forms when moving water in a stream erodes the outer banks and widens its valley where as the inner part of the river has less energy which results in deposition. Meandering channels is a vast research area, covering a broad range of time and space scales, environmental r...

Abstract: Geomorphic effectiveness of the August 2006 flood in the middle and lower reaches of the Tapi river has been quantitatively assessed in this paper. Flood hydrograph available for this flood revealed that the duration of flood ranged from 10 to 11 days. The channel response to such long duration floods, particularly in alluvial sections, i...

In this study, an attempt has been made to evaluate the temporal variations in specific stream power and the total energy available for geomorphic work during the monsoon season for the Tapi River, in central India. Continuous daily discharge data (1978–1990), hydraulic geometry equations and the relationship between discharge and water surface slo...

In this paper an attempt has been made to quantitatively evaluate the geomorphic effectiveness of three large-magnitude floods that occurred in 1959, 1968 and 1969 in the lower Tapi Basin. Flood hydrographs available for these and other flood events show that the duration of floods can range from 6 to 10 days, and in exceptional cases up to 15 days...

The Pleistocene-Holocene palaeohydrological and palaeoenvironmental conditions of the Deccan Trap rivers are not well-established. This is mainly on account of the limited extent of alluvial deposits and scarcity of palaeochannels to estimate former river discharges. This paper reports the results of recent investigations of a palaeochannel and the...

Geomorphic effects of floods are a function of several controlling factors, such as magnitude, frequency, rate of sediment movement, flood power, duration of effective flows, sequence of events and the channel geometry. In this paper, these measures of effectiveness have been evaluated for the monsoon-dominated, flood-controlled and incised Tapi Ri...

The rivers of the southern part of the Indian Peninsula are monsoonal in nature and the hydrological characteristics of these rivers djffer markedly from those of Himalayan rivers. The rivers are subjected to severe floods during the monsoon season. In the last few decades, several large-magnitude floods (peak floods between 10,000 and 80,000 m/s)...
