An urban watershed in Xiamen was selected to perform the parameter uncertainty analysis for urban stormwater runoff modeling in terms of identification and sensitivity analysis based on storm water management model (SWMM) using Monte-Carlo sampling and regionalized sensitivity analysis (RSA) algorithm. Results show that Dstore-Imperv, Dstore-Perv and Curve Number (CN) are the identifiable param...

A high-speed highway in the design encounters many problems, for solution of which it is necessary to find best ways. One these problems overheating wire contact network (CN) when passing through neutral insert. The authors propose an insulating connection device (ICD) CN, will allow avoid occurrence electric arc, and, consequently, and subsequent failure wire. ICD CN a set resistances that cha...

Let D be a finite simple directed graph with vertex set V(D) and arc set A(D). A function ( ) { } − : 1,1 f V D → is called a signed dominating function (SDF) if [ ] ( ) 1 D f N v − ≥ for each vertex v V ∈ . The weight ( ) f ω of f is defined by ( ) ∑ v V f v ∈ . The signed domination number of a digraph D is ( ) ( ) { } γ ω = min is an SDF of s D f f D . Let Cm × Cn denotes the cartesian produ...

The lack of hydrological data for urbanizing watersheds in developing countries is one of the challenges facing decision making. Msimbazi River is located in the city center of Dar es Salaam and is highly influenced by human activities; this includes dense populations that are characterized by informal settlements. The catchment is currently undergoing flooding, which triggers a dilemma in its ...

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...

Abstract The Soil Conservation Service Curve Number (SCS-CN) method was applied to calculate the runoff in Khur khur watershed (KHW) based on (GIS and RS) techniques. is located southeast of Iraqi Kurdistan region northeast Iraq foothill zone. total area (106.84) km 2 , fifth order, it meets Sirwan river. study aim speculate annual volume select dam site order harvest water from (KHW). research...

Urban planning is associated with land transformation from natural areas to modified and developed ones which leads to modification of natural environment. The basic knowledge of relationship between both should be ascertained before proceeding for the development of natural areas. Changes on land surface due to build up pavements, roads and similar land cover, affect surface water flow. There ...

Changing of precipitation regime and intensification extreme storms in semi-arid regions because climate change requires the use numerical models to forecast outlet hydrographs. In this paper, HEC-HMS software was applied using a loss method curve number CN estimate excess parametric unit hydrograph model compute transformation into direct runoff over watershed. The Muskingum-Cunge routing used...
