Hydrological variations hold a significant influence over the water chemistry in karstic critical zone. In this context, Baget Catchment (BC) has been monitored at high resolution two years outlet order to set up typology of flood events. The objective was assess multiple streamwater physico-chemical patterns response hydrological variations, streamflow component (quick-response, subsurface, an...

The paper discusses the application of a chain mathematical models for calculating glacial debris flow. Modeling was carried out Bodomdara River valley case an outburst Lower Lake (Gorno-Badakhshan Autonomous Region, Tajikistan). FLOVI program, written in Python programming language, applied; it combines equations lake hydrograph and characteristics flow during its formation. To calculate flood...

Flash flood disaster ranks top among all the natural hazards across world due to its high frequency, severity and fatality. However, flash simulation is still challenging in small medium-sized catchments with complex orography, flashy hydrological responses poor observations. Three distributed models, i.e., TOPModel, HEC CNFF, are selected simulate floods seven humid six semi-humid China, consi...

Estimation of parameters of a hydrologic model is undertaken using a procedure called “calibration” in order to obtain predictions as close as possible to observed values. This study aimed to use the particle swarm optimization (PSO) algorithm for automatic calibration of the HEC-HMS hydrologic model, which includes a library of different event-based models for simulating the rainfall-runoff pr...

Determining the rain pattern distribution is believed to affect design flood. Providing hourly rainfall observations can be obtained, and patterns determined. However, in areas that do not have one, flood discharge calculations are carried out by distributing daily using empirical methods. This study distributes into Jangkok watershed ABM Mononobe methods calculates hydrograph Nakayasu model. T...

The Design Flood (DF) concept is an essential tool in designing hydraulic works, defining reservoir operation programs, and identifying reliable flood hazard maps. purpose of this paper to present a methodology for deriving hydrograph considering the epistemic uncertainty. Several appropriately identified statistical distributions allow acceptable approximation frequent values maximum discharge...

Debris flow is a natural phenomenon that can cause some damage and fatalities. from Mount Merapi frequently happens through the Putih River, so it necessary to do research. Anticipating occurrence of debris flows be done with predictions reduce number casualties material losses. This research used simulation method based on Ashida, Takashi, Mizuyama equation applied Nakayasu synthetic unit hydr...

Improving the predictive capabilities of rainfall-runoff models in ungauged catchments is a challenging task but has important theoretical and practical significance. In this study, we investigated the predictive capabilities of the conceptual Xinanjiang model (XAJ), which is widely used for flood forecasting and simulation in China, in ungauged catchments. We further produced a hybrid rainfall...

A new era involving both simple and complex hydrologic modeling of un-gauged river basins may now emerge with the anticipated global availability of high resolution satellite rainfall data from the proposed Global Precipitation Measurement (GPM ) mission. This era of application pertains to rapid prototyping of GPM-based flood monitoring systems for downstream nations in International River Bas...
