High-resolution analysis of hydraulic response characteristics of silted stormwater pipeline and manholes in urban catchments using GASM-TranGRU and CFD-DEM
Published 2025-12-01“…The pipe with a transverse siltation intensity of 10% showed an 8.07% reduction in the maximum overflow flow rate, whereas the pipe with a longitudinal siltation intensity of 5.2% exhibited a 15.09% reduction, suggesting that longitudinal siltation intensity has a more significant impact on pipeline failure.Conclusion:The research results provide technical support for the diagnosis of pipeline siltation and flood risk assessment considering the change of water level in the manhole and the inlet and outlet flow velocity of the pipe section.…”

An explainable Bayesian gated recurrent unit model for multi-step streamflow forecasting
Published 2025-02-01“…The analysis of uncertainty quantization shows that noise in the input data is the primary source of overall uncertainty in model prediction, whereas a notable increase is observed in the uncertainty caused by the model in the flood season. Furthermore, the application of the SHAP method reveals the critical role of water level in streamflow prediction.…”

Precipitation Concentration in Bangladesh over Different Temporal Periods
Published 2018-01-01“…Precipitation concentration is an important component of climate, and an unbalanced distribution of precipitation can yield excess or scarcity of water resources, which in turn can influence plant growth, flood risk, and water resource use. The precipitation concentration index (PCI) is a well-known indicator for the measurement of temporal precipitation in a short or long area. …”

Temporal and Spatial Evolution Characteristics of Extreme Climate Events in Grand Shangri-La Region from 1961 to 2019
Published 2022-01-01“…The Grand Shangri-La region connects the Qinghai-Tibet Plateau,the Yunnan-Guizhou Plateau,and the Hengduan Mountains and is of great geographical significance.Five rivers flow through the region,and the climate is vulnerable.Therefore,it is necessary to explore extreme climate changes and their response mechanism,so as to assess regional climate risks and achieve disaster warnings.Based on the daily temperature and precipitation data of 56 meteorological stations from 1961 to 2019,this paper analyzes changes in extreme climate indexes and their correlation with large-scale circulation index in the region by using Mann-Kendall,Sen's slope estimation,Pettitt test,and Pearson correlation analysis.The results show that:① The extreme warm index and the extreme precipitation intensity index (RX1day,R95p,R99p,and SDII) increase significantly,while the cold index (CSDI、FD、ID、TN10p、TX10p) and the number of continuous humid days decrease greatly.In terms of different seasons,the warming amplitude of most of the extreme temperature indexes in winter is higher than that in summer,and the precipitation intensity increases gradually in summer and autumn but decreases slightly in winter.② Spatially,the diurnal temperature range in the north of the Qinghai-Tibet Plateau is higher than that in the south,and the frequency of extremely high-temperature rises,with the high temperature appearing mostly in arid valleys in the south and east of the Qinghai-Tibet Plateau.The precipitation intensity is high in the south and west of the Hengduan Mountains,and persistent precipitation is strong in the Yalong River basin and the upper reaches of the Jinsha River in the north.③ Extreme climate indexes and south China sea summer monsoon index (SCSMI) are significantly correlated in the same year.In addition,there is a one-year response lag between the extreme precipitation index and Arctic oscillation (AO),North Atlantic oscillation (NAO),and Pacific decadal oscillation (PDO).The above analysis shows that the Grand Shangri-La region generally shows warming and humid climate characteristics.The frequency of heavy precipitation in flood season and warm winter events increases and is closely related to large-scale circulation.…”

Quantifying soil surface erosion
Published 2024-12-01“…While this loss of solid matter induced by all kinds of fluid flows on the surface of soils is often a source of beauty in the landscapes that surround us, it also constitutes a major risk and poses growing threats in the context of global change as loss of agricultural soil fertility, decline in coastal ecosystems or increase in safety standards for flood protection structures. It is therefore essential to be able to predict future soil removal rates at multiple scales, in order to anticipate or mitigate their impacts. …”

Design of a Solar Powered Precision Irrigation System.
Published 2023“…Statistics show that Sprinklers waste 30 to 50 percent of water through evaporation, runoff and apply water where it isn't needed and other factors. Flood irrigation wastes between 40 to 65 percent of the water due to factors like overtopping, runoff in the drain, rat holes in the canal bunds, evaporation from the water surface among others. [ 1] This is also accompanied by the fact that most used energy sources are fuel energy since hydro electrical energy (HEP) is not extended in most rural areas where actual agriculture is practiced and even the few rural areas having the hydroelectric power face frequent black outs thus leaving H.E.P unreliable thus fossil energy source the only alternative. …”
