Complicated research and management questions regarding watershed systems often require the use of more than one simulation model. Therefore, it is necessary to develop a means to integrate multiple simulation models to predict holistic system response. In this paper we explore the use of a componentbased approach for the runtime integration of models, implemented as “plugand-play” software com...

One of the challenges in rainfall-runoff modeling is identification an appropriate model spatial resolution that allows streamflow estimation at customized locations river basin. In lumped modeling, not issue as variability accounted for, whereas distributed grid or cell can be related to but its application limited because large data requirements. Streamflow data-poor possible it challenging m...

Floods have become more severe and frequent as a result of climate change around the world, posing hazard to public safety economic development. This study investigates use distributed hydrological models in flash flood risk management small watershed Hazara, Pakistan, with goal improving Pakistan's early warning lead time. First, HEC-HMS model was built using geographic data river network's st...

Rainfall-runoff simulation is vital for planning and controlling flood control events. Hydrology modeling using Hydrological Engineering Center—Hydrologic Modeling System (HEC-HMS) accepted globally event-based or continuous of the rainfall-runoff operation. Similarly, machine learning a fast-growing discipline that offers numerous alternatives suitable hydrology research’s high demands limitat...

Abstract Discrepancies between estimated sediment and actual yields are large. The sedimentation often causes severe damage due to a lack of on-site measurement data in the current disaster prevention system. This paper presents robust early-warning system which statistical analysis used predict is conducted within context underlying physical mechanisms. three-phase employs collection, generati...

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...

Abstract Floods are one of the extreme events and widespread natural disasters that significantly affect civil infrastructure livelihood people. Recently, climate change has affected rainfall pattern increased flood worldwide, especially in India. Therefore, it become essential to map potential inundation regions for various future developing appropriate mitigation management strategies. This s...
