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 presents the application of a real-time decision support system (DSS) for power generation and flood control at the Thac Xang hydropower plant in Lang Son province, Vietnam. The DSS consists of three key components: real-time operation and visualization, forecast, and optimized decision modules.

Researches on combinion of hydrological and hydrodynamic models are very important when performing risk assessment and disaster management, including saline intrusion, which is especially important for watersheds, with limited measurement data. The objective of this study is linking two types of hydrological and hydrodynamic models to simulate the scope of salinity intrusion in the Ve estuary, Quang Ngai province.

The indicators of climate change in Central Europe, Hungary is showing a trend of decrease in rainfall, increase in temperature and especially extreme weather that is becoming more usual and unpredictable. The current study presents the application of the MIKE SHE model to examine the role of unsaturated soil settings and the effects of climate change on various hydrological parameters and water balance components.

Flood is one of the most commonly occurring forms of natural disaster which damage to environment and society. In order to contribute to the work of mitigating the effect of climate change as well as floods' damage, this study introduces a method to simulate discharge with respect to design storm through hydrological modeling system (HMS).

In this study, Poko river basin is selected for evaluation of water resources in the basin, as there is a decline inflow due to reduced rainfall over years and also due to increased activities in the upstream areas of the catchment. The study focused on evaluation of hydrological components for Poko river basin using hydrological model known as soil and water assessment tool (SWAT).

The hydrological models are typically classified in stochastic, lumped conceptual and detailed physically-based models. Among these models, only physically-based models consider spatial distribution of driving factors and describe the physical processes by mathematic equations. In this study, the semi-distributed model QSWAT model is selected to simulate the flow to Dak Wi reservoir in Kon Tum province.

Many stochastic processes in practice having the sequences of random variables are generally skewed and dependent and to solve these problems, the application of first-order gamma autoregressive (GAR(1)) model[4] is very effective; especially in the study of streamflow simulation in Stochastic Hydrology. This paper mainly presents the study of Gar(1) model in the simulation of monthly streamflows. To reach this aim, we study Thomas-Fiering model and proposed the Gar(1)-Fragments model.

Three main approaches have been generally proposed to the flood forecasting including: i) physical models, ii) statistical models and iii) data-driven models. The first approaches, also called hydraulic models, aims to reproduce the hydrological processes in a physically realistic manner and is based on mathematical formulas of conservation of mass, momentum and energy.

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.

Precipitation downscaling improves the coarse resolution and poor representation of precipitation in global climate models, and helps end users to assess the likely hydrological impacts of climate change. This paper integrates perspectives from meteorologists, climatologists, statisticians and hydrologists, to identify generic end user (in particular impact modeler) needs, and to discuss downscaling capabilities and gaps.

Hydrological models can simulate water balance and predict water behaviors in any catchments; however, accuracy of model always is questioned. Therefore, calibration and validation processes are required for any models to acquire realistic expectations. TETIS model is a conceptual distribution model applied to simulate dynamic of hydrology based on water balance calculation, sediment erosion, and other constituents.

The present study, it concluded that remote sensing techniques (ASTER–DEM) coupled with GIS can be a powerful tool in morphometric analysis of a region or basin and the data can be used for hydrological studies and water resource management. In the present study the liner and areal aspect parameters were calculated. The major parameters were Drainage density, stream order and Bifurcation ratio were play major role for hydrological processing and the values were, 0.58, 1-5 th order and 4 respectively.
