Hydrological river flow model

This study utilized the GIS-based Soil and Water Assessment Tool (SWAT) model to simulate the flow of Vu Gia - Thu Bon river basin at two hydrological stations - Nong Son and Thanh My, during the calibration period (2004 - 2010) and the verification period (2011 - 2015). The evaluation results of both periods, as measured by the NSE and R2 indexes, were found to be above 0.75.

This study applied an integrated surface water-groundwater (SW-GW) model, SWAT-MODFLOW to study interaction of surface and groundwater than simulate saltwater intrusion at a regional scale in Da Nang coastal city. Model components were calibrated and validated using monthly river flow data and hydraulic head data for the 2005-2020 period and showed good agreement with observed data.

This paper examines the effects of reduced water flow by upstream dams’ operation and river bed incision on saltwater intrusion in the Mekong Delta. In that regard, long-term water flow at two upstream hydrology stations from 1980 to 2020 and river bed incision from 2009 to 2017 were analyzed.

Flooding caused by historically high flows, especially in Tra Khuc-Ve River basin in the Mid-Central region in Vietnam in November 2013, which caused widespread damage. The purpose of this paper was to establish the inundation maps in the downstream part of Tra Khuc-Ve rivers by using the coupling of the hydrological and hydraulic models (MIKE SHE/MIKE 11 and MIKE 11 GIS). Calibration and validation of the hydrological model were in good agreement in terms of the vibration amplitude, absolute value, and phases.

Watersheds are natural hydrological entities that cover a specific aerial expanse of land surface from which the rainfall runoff flows to a defined drain, channel, stream or river at any particular point. In the last two decades, watershed management has gained the top most priority in water resources sector necessitating delineation of watersheds upto mini watershed level in order to take up watershed development and management programmes. Prerequisite for watershed management is knowledge of watershed characteristics like slope, relief, aerial extent and drainage networks.

A realistic new sediment–laden water prediction computer model was developed. In this model unsteady non-uniform flow computations were incorporated. Using this model, flooding flow–sediments were simulated and compared to earlier research including hydrologic engineering centre (HEC-series) computer models. Uncertain value of parameters and errors in flow–sediment transport equation in existing coupled flow–sediment models were studied.

This study aimed to apply the Variable Infiltration Capacity (VIC) hydrological model for simulating the daily river flow during the period of 2005-2014 for the Red River System, Vietnam. For this purpose, the VIC-3L hydrological model forced with satellite meteorological datasets was set up for the Red River Basin at the spatial scale of 0.1o × 0.1o (~11km × 11km).

The comparison shows that the accuracy of our hydrological river flow model is over 90% during flood peak time of raining season. Flooding has become a catastrophic disaster recently in many cities. Flood model based the satellite images, fuzzy logic evaluation, and water capacity sensors in river were studied while GIS has been applied to various applications.

The frequency analysis of the largest, or the smallest, of a sequence of hydrologic events has long been an essential part of the design of hydraulic structures. Therefore, the question of better fit among countless probability models used in frequency analysis is always a fresh one.

The model was applied to forecast the discharge into Hoa Binh reservoir in the flood season 2006. The difference of this connected hydraulic-hydrological model in comparison with the other hydrological models is using the complete Saint-Venant 1D to simulate flow in rivers. Results of verification of the model show that it is good enough for practice.
