Water is one of the most valuable natural resources and a vital component socioeconomic development nation. in India throughout world are under lot stress as result limited supply rising demand. availability region can be better estimated using rainfall runoff relationship. Runoff mostly produced rainfall, which significant part hydrologic cycle. In this study, rainfall-runoff relation Bamnidhi...

The physically-based flood frequency models use readily available rainfall data and catchment characteristics to derive the flood frequency distribution. In the present study, a new physically-based flood frequency distribution has been developed. This model uses bivariate exponential distribution for rainfall intensity and duration, and the Soil Conservation Service-Curve Number (SCS-CN) metho...

In this paper we study the effect of introducing nitrogen into different carbon networks. Two kinds of carbon nitride films were deposited: (a) Using a DC-magnetron sputtering system sp bonded carbon nitride (a-CN) films were deposited and (b) Using a 2 combination of filtered cathodic vacuum arc and a low-pressure N plasma source, N was introduced into sp carbon networks 3 2 (ta-C), leading to...

Simulation of the runoff-rainfall process in forest lands is essential for land management. In this research, a hydrologic modelling system (HEC-HMS) and artificial neural network (ANN) were applied to simulate rainfall-runoff (RRP) Kasilian watershed with an area 68 square kilometres. The HMS model was performed using secondary data rainfall discharge at climatology hydrometric stations, Soil ...

Forest fire is a common concern in Mediterranean watersheds. Fire-induced canopy mortality may cause the degradation of chemical–physical properties soil and influence hydrological processes within across However, prediction pedological effect forest fires with heterogenous severities entire watersheds remains difficult task. A large occurred 2017 northern Italy providing opportunity to test an...

The present study aims to investigate the hydrological response of small coastal watersheds storm events. Areas around Mediterranean Sea are usually characterized by streams with intermittent flows and flash floods common. Firstly, we analyze geomorphological, soil land cover characteristics watershed in order estimate their effect on surface runoff. Furthermore, rainfall an extreme event that ...

This paper describes the use of a simple two stage rainfall-runoff model in which a curve number (CN) principle is used to calculate the soil water content and, subsequently, the rainfall contribution to direct runoff and groundwater flow. The maximum soil water retention, S, is used to express various characteristics of a catchment (infiltration rate, soil cover and land use, as in the CN meth...

This study calibrated the Soil Conservation Service Curve Number (SCS-CN) model to predict decadal runoff in Peninsula Malaysia and found a correlation between reduction of forest area, urbanization, an increase volume. The conventional SCS-CN was commit type II error this must be pre-justified with statistics before being adopted for any prediction. Between 1970 2000, deforestation caused decl...

BACKGROUND The aim of this study was to determine the optimal strategy among various arc arrangements in prostate plans of stereotactic body radiotherapy with volumetric modulated arc therapy (SBRT-VMAT). PATIENTS AND METHODS To investigate how arc arrangements affect dosimetric and biological metrics, SBRT-VMAT plans for eighteen patients were generated with arrangements of single-full arc (...
