Integration of Morphometric Analysis and Synthetic Unit Hydrograph Methods for Hydrological Assessment in the Warana River Basin, Maharashtra, India | Chapter 4 | Engineering Research: Perspectives on Recent Advances Vol. 4

This study aims to develop and evaluate average representative unit hydrographs (UHs) for the upper Warana River basin, Maharashtra, India, based on isolated storm events. Synthetic Unit Hydrographs (SUHs) were constructed using four established methods: Snyder’s modified method, Soil Conservation Service (SCS) dimensionless hydrograph, Central Water Commission (CWC) method, and Commons' dimensionless hydrograph. The SUHs were assessed for ungauged basins with similar hydrological characteristics, and their correlation coefficients were calibrated and validated. Morphometric analysis of the basin indicated moderate to high flood potential and moderate recharge capacity for the Warana River basin, with Sub-basins 1 and 3 exhibiting similar characteristics, while Sub-basin 2 showed low flood potential and high recharge capacity. Snyder’s method emerged as the most effective approach, yielding a peak discharge percentage error of 0.26% for the Warana River basin and 0.32% for Sub-basin 1. The Snyder coefficients C_p =0.55 and 𝐶_𝑡=1.06 were found to be suitable as regional coefficients for basins with analogous hydroclimatic conditions. Comparative analysis revealed that Snyder's SUH closely aligned with observed UHs, demonstrating high reliability for runoff prediction. The successful validation of Snyder’s model underscores its utility in water resources management, enabling accurate flood prediction, water allocation, and reservoir operation. These findings establish Snyder’s SUH as a robust tool for hydrological modelling in ungauged basins with similar hydroclimatic settings.

Use of NRCS Model Approach in a Watershed without Landcover Data | Chapter 7 | Research and Developments in Engineering Research Vol. 5

 This branch highlights the request of NRCS Model to Watershed Having No Landcover Data. In the current study, the length and slope limits of a watershed are used to request the NRCS model with a speed factor judging technique. According to the features of the Kirpich formula and speed relationship, the time and slope data maybe used to directly decide the flow velocity for a container or area where water is held. The model is applied to two ungauged watersheds, Madhura and Ghagra situated in Barak basin in India to receive triangular UH administering NRCS technique. Drainage network for the watersheds and the geomorphologic limits are estimated utilizing 30m-ASTER DEM. Geographic Information System (GIS) is a potentially persuasive tool in displaying spatially varied methods. Most of the geomorphologic parameters that are necessary for developing UH for a turning point are spatially varied and many authors have secondhand GIS in estimating geomorphic IUH/UH for a container or area where water is held. Length and average slope values for the watersheds are supposed using GIS method. Peak UH results produced utilizing the model are contrasted accompanying prior GIUH results; a contrasting of the model performances discloses that the NRCS model performs likewise when the velocity determinant is calculated utilizing length and slope variables. Watersheds that are not measure and for which skilled are no data toward cover characteristics will benefit from the inclusion of the novel velocity belief technique into the NRCS model.
