the major problem in the assessment of relationships between rainfall and runoff occurs when a study is carried out in ungauged watersheds in the absence of hydro-climatic data. this study aims to evaluate the applicability of natural resources conservation service-curve number (nrcs-cn) method together with gis in estimating runoff depth in a mountainous watershed. the study was carried out in...

This study attempts to validate an infiltration model, the Soil Conservation Service–Curve Number (SCS–CN) method, using nonofficial intermittent occurrence data of Eongtto Falls on Jeju Island, Korea. Simply due limited official continuous runoff concerning validation a newly set SCS-CN method for Island was practically impossible. Instead, this tries use purpose. focuses Falls, which is one m...

The Soil Conservation Service Curve Number (SCS-CN) approach is widely used as a simple method for predicting direct runoff volume for a given rainfall event. The CN parameter values corresponding to various soil, land cover, and land management conditions can be selected from tables, but it is preferable to estimate the CN value from measured rainfall-runoff data if available. However, previou...

This study presents a revised and calibrated Soil Conservation Service (SCS) curve number (CN) rainfall runoff model for predicting in Malaysia using new power correlation Ia = SL, where L represents the initial abstraction coefficient ratio. The traditional SCS-CN with proposed relation 0.2S is found to be unreliable, exhibits improved accuracy. emphasizes need design flood control infrastruct...

Flood prediction is very important in land and water resources management. Many flood disasters could be mitigated with adequate preparedness especially urban watershed. This study assessed the runoff potential of Opa watershed Southwest Nigeria using remote sensing Soil Conservation Service or SCS curve number (CN) techniques. The 2007 NigSat image year was classified into different cover clas...

The Soil Conservation Service Curve Number runoff model is widely used in runoff prediction and has been incorporated into many software packages for watershed modeling. The Curve Number (CN) is the key parameter in the model, but it is largely dependent on Hydrologic Soil Group (HSG) classifications which may induce aggregation of detailed soil information. However, little attention and effort...

Suburban growth and its impacts on surface runoff were investigated using the soil conservation service curve number (SCS-CN) model, compared with integrated advanced remote sensing geographic information system (GIS)-based approach, over South Kingston, Rhode Island, USA. This study analyzed employed supervised classification method four Landsat images from 1994, 2004, 2014, 2020 to detect lan...

In any hydrologic study, the most important parameter is runoff which necessary for designing hydraulic structure, and determining risk of flood. As there a scare in availability data many sites, hydrologists have developed indirect methods to determine accelerate program watershed management conserving developing water resources management. Many are used estimate runoff; Soil conservation curv...
