The Soil Conservation Service Curve Number Model is a conceptual model intended for estimating effective rainfall (ER). This grounded in parameter – referred to as (CN), which determined from information on the characteristics of watershed. Standard Method (M1) determining CN based soil and land-use tables; however, some authors have proposed alternative methodologies defining value monitored r...

Rainwater harvesting is an important step towards maximizing the water availability and land productivity in arid semi-arid areas. The present study shows that area of Ghazi Tehsil within Khyber Pakhtunkhwa Province, Pakistan, has great potential for rainwater due to its feasible climatic topographic conditions. This 348 km2 normally receives high rainfall annually, but, hilly terrain, bulk los...

The aim of the article was to verify curve number (CN) values given in National Engineering Handbook (NEH) methodology, whether they really correspond all wide-row crops. tested crops were maize, hops and potatoes grown using conventional soil conservation technologies. All these are classified as crops, but very different terms cultivation process. basis for calculation our CN field measuremen...

parameters as interception, infiltration, water storage on surface holes and soil profile, evapotranspiration are factors of loss water in a watershed and avoid from changing of precipitation to runoff. in this study, by use of hec-hms model and comparison of results of different methods of precipitation loss evaluation (initial and constant, green & ampt, scs curve number, deficit & constant a...

HEC HMS merupakan salah satu aplikasi pemodelan yang dapat digunakan untuk memodelkan nilai limpasan harian maupun bulanan berdasarkan karakteristik DAS. Tujuan penelitian ini adalah 1) Mengkaji fisik DAS Serang direpresentasikan oleh curve number (CN) 2) aliran berupa debit puncak, volume outflow, dan waktu puncak dari hidrograf banjir terukur dengan hasil menggunakan HEC-HMS. Nilai CN ditentu...

Depth-duration analysis, such as accomplished for rainfall, can be useful in the analysis of infiltration of rainfall. The assessment of infiltration depth-duration in terms of return frequency is of interest. In this paper, depth-duration values of daily rainfall infiltration are estimated using the National Resources Conservation Service (NRCS) Curve Number (CN) approach for estimating daily ...
