Dam break study of Myntdu Leska Dam in Meghalaya using DAMBRK model – research output (2000-01)

This report by National Institute of Hydrology presents a study of the hypothetical failure of Myntdu Leska dam in the southern part of Meghalaya near the international Indo-Bangladesh border. The maximum water level attained by the dam break flood in the river downstream of dam has been calculated and ascertained for extent of submergence of the area.

Furthermore, the dam break flood wave characteristics at four different sections downstream of the dam have been determined for different failure characteristics. The sensitivity studies of the various parameters have also been done to know their effect over the movement of dam break flood wave.

The safety of the downstream area of dam against its possible failure is one of the most important aspects to be considered during the planning, design, construction and operation of the dam. Flood wave due to a failure always assumes large magnitudes and inundates large area in the downstream portion.

The DAMBRK model developed by the US National Weather Service (NWS) attempts to represent the current state-of-art understanding of dam failures and the utilization of hydrodynamic theory to predict the dam break wave formation and downstream progression. The model has wide applicability and can function with various levels of input data ranging from rough estimates to complete data specification.

The study concludes that the spillway capacity is sufficient enough to pass the peak of the most severe flood (PMF) even when the reservoir is at Full Reservoir Level (FRL) and therefore the dam will not fail by overtopping. The dam may fail by breaching for which the study has been done. The reservoir storage is very low while the carrying capacity of the river is very high in general. Therefore, the dam break flood does not spill at any location except at Ch-6.93 km. Even at this section the peak of flood hydrograph passes safely as the water spread is sufficient.  Read the study

Uncertainty analysis of GIUH based Clark model using first order analysis for a catchment of Lower Godavari sub-zone – research output (1999-2000) 

In this study, uncertainty analysis has been carried out for the parameters of the mathematical model developed at National Institute of Hydrology for estimation of the Clark model parameters using the geomorphological characteristics of an ungauged catchment. The model has been applied for simulation of direct surface runoff (DSRO) hydrographs of the catchment defined by bridge number 807 of the Lower Godavari sub-zone 3 (f).

Uncertainty analysis outlines the inability to exactly model a real world hydrologic situation even if the best possible estimates of the input parameters of the model are utilized. An added complication with most of the hydrologic models is that in general these models are structured with several uncertain input parameters. The sources of uncertainty in model output are model structure itself and the uncertainty associated with the parameter of the model.

The geomorphological parameters of the catchment have been evaluated using the Geographical Information Systems (GIS) package Integrated Land and Water Information Systems (ILWIS). The direct surface runoff hydrographs estimated by the Geomorphological Instantaneous Unit Hydrograph (GIUH) approach has been compared with the observed direct surface runoff hydrographs as well as with the DSRO hydrographs simulated by the Nash model and the HEC-1 package.

The performance of the GIUH model has also been evaluated by employing some of the error functions viz., (i) efficiency (EFF) (ii) the absolute average error (AAE) (iii) root mean square error (RMSE) (iv) average error in volume (AEV) (v) percentage error in time to peak (PETP) computed based on the observed and the simulated DSRO hydrographs. It is observed that the DSRO hydrographs computed by the GIUH based Clark model approach, which simulates the DSRO hydrographs of the catchment considering it to be ungauged, compare reasonably well with the observed and the simulated DSRO hydrographs.

For carrying out the uncertainty analysis, the geomorphological parameters viz length ratio (RL), length of the highest order stream (LΩ), length of the main stream (L) and the velocity parameter (V) apart from the aforementioned geomorphological parameters, have been considered.

Relative sensitivity analysis has been conducted for identifying the parameters of the GIUH based Clark model, which significantly affect peak of the unit hydrograph on the basis of their relative sensitivity coefficients. Uncertainty analysis has been carried out by first order analysis (FOA). Also, upper and lower 95 per cent confidence limits for the peak of the unit hydrograph derived by the GIUH based Clark model have been computed. Read the study
