Rainfall runoff modeling is one of the most complex hydrological due to involvement different watershed physical parameters. It essential for analysis response towards received precipitation under influence variables. As it a replica response, Rainfall-Runoff evaluate general characteristics total surface at catchment’s outlet. The main objective this study was prediction rainfall using Hydrolo...

• MSME estimates of direct runoff outperformed the SCS-CN on poorly-drained catchments. Antecedent moisture condition lowlands was defined by initial water table level. Soil saturation coefficient divided into subsurface and surface runoff. A threshold event rainfall depth found for generation. has potential to assess land use changes climate variability. In this study, we calibrated tested Con...

For a strong oriented graph D of order n and diameter d and an integer k with 1 ≤ k ≤ d, the kth power D of D is that digraph having vertex set V (D) with the property that (u, v) is an arc of D if the directed distance ~ dD(u, v) from u to v in D is at most k. For every strong digraph D of order n ≥ 2 and every integer k ≥ ⌈n/2⌉, the digraph D is Hamiltonian and the lower bound ⌈n/2⌉ is sharp....

Permeable pavements are a green infrastructure stormwater management practice that can serve as functional component of the site design. However, previous field studies suggest high uncertainty in parameters used for performing hydrologic calculations permeable pavements. The Environmental Protection Agency (EPA) Storm Water Management Model (SWMM) within PCSWMM software package was to simulate...

In the field of operational flood forecasting, uncertainties linked to hydrological forecast are often crucial. In this work, data assimilation techniques are employed to improve hydrological variable estimates coming from numerical simulations using all the available real-time water level measurements. The proposed assimilation scheme, a classical Kalman filter extension to non-linear systems,...

Global optimization methods linked with simulation models are widely used for automated calibration and serve as useful tools for searching for cost-effective alternatives for environmental management. A genetic algorithm (GA) and shuffled complex evolution (SCE-UA) algorithm were linked with the Long-Term Hydrologic Impact Assessment (L-THIA) model, which employs the curve number (SCS-CN) meth...

Electrically conductive amorphous carbon nitride (a-CN) coatings were deposited onto various substrates by pulsed vacuum-arc sputtering of a graphite cathode with simultaneous irradiation the substrate nitrogen ions. Deposition temperature was less than 60 °C. We investigated effect vacuum annealing at 600°С on elemental composition, structure, electrical and optical properties obtained films. ...

Flash floods are water-related disasters that cause damage to properties, buildings, and infrastructures in the flow path. often occur within a short period of time following intense rainfall high, mountainous area northern Thailand. Therefore, purpose this study is generate flash flood susceptibility map using watershed morphometric parameters hydrological approaches. In study, Pai River basin...
