Percolation tanks are widely used for increasing recharge of ground water resources. This has been used from centuries in arid and semi arid regions of India and is known by different indigenous name, viz. rapat, nadi etc. However not much work has been done on standardization of the design...

This paper presents a quantitative evaluation of the existing Soil Conservation Service Curve Number (SCS-CN) model, its variants, and the modified Mishra and Singh (MS) models for their suitability to particular land use, soil type and combination thereof using a large set of rainfall-runoff...

The general soil conservation service curve number (SCS-CN)-based Mishra and Singh (Mishra and Singh, 1999, J. Hydrologic. Eng. ASCE, 4(3), 257–264) model and its eight variants were investigated for their field applicability using a large set of rainfall-runoff events, derived from a number...

The present study investigates experimentally the effect of watershed (i.e. field plot of 22 m × 5 m) slope on rainfall-generated runoff and, in turn, the runoff curve numbers (CN) resulting from field plots (with land use of maize and sugarcane on the soil falling in Hydrologic Soil...

The available antecedent moisture condition (AMC)-dependent runoff curve number (CN) (SCS, National Engineering Handbook, Supplement A, Section 4, Chapter 10, Soil Conservation Service, USDA, Washington, DC, 1956) conversion formulae due to Sobhani (M.S. Thesis, Utah State University, Logan, UT,...

Employing a large dataset of 84 small watersheds (area=0.17 to 71.99 ha) of U.S.A., this paper investigates a number of initial abstraction (I <Subscript> a </Subscript>)-potential maximum retention (S) relations incorporating antecedent moisture (M) as a function of antecedent precipitation (P <Subscript>5</Subscript>), and finally...</subscript></subscript>

A new lumped conceptual model based on the Soil Conservation Service Curve Number (SCS-CN) concept has been proposed in this paper for long-term hydrologic simulation and it has been tested using the data of five catchments from different climatic and geographic settings of India. When compared...

The “Eight Communities of the Chianti” area, Tuscany, Italy, receives an average annual rainfall of 700–800mm, mainly between September and December. Nevertheless, the storage capacity of the soil is not sufficient to fulfill agricultural requirements, resulting in a shortage of water from...

Taking surface runoff of Coastal Highway in Liaoning Province as research object, this paper analyzed water quality characteristics of runoff and flow rules of pollutants. It proposed using constructed wetland treatment technique in the drainage system from the perspective of effectively...

Water availability is at the core of sustainable socioeconomic development and ecological conservation along with global climate and land use changes, especially in the areas that experience water problems. This study investigated the impacts of land use change on surface runoff and water yield...
