Observed differences between water balance for temperate and semiarid catchments can be attributed to variability in the primary controls of soil profile (soil storage capacity permeability), vegetation (surface coverage use efficiency), climate (rainfall potential evaporation). Motivated by downward development methodology mooted Klemes [1983], this paper explores underlying landscape interactions that cause a number benchmark around Australia. A systematic parsimonious analysis based...

Two uses of the terms “linearity” and “nonlinearity” appear in recent literature. The first definition nonlinearity is with respect to dynamical property such as rainfall‐runoff response a catchment, this sense refers nonlinear dependence storm on magnitude rainfall inputs [ Minshall , 1960 ; Wang et al. 1981 ]. second Huang Willgoose 1993 Goodrich 1997 ] catchment statistical property, mean annual flood, area catchment. They are both linked important interconnected hydrologic concepts,...

A space‐time rainfall model is constructed to generate synthetic fields of rainfall, with a daily time step. The has two components: temporal based on first‐order, four‐state discrete Markov chain which generates series the regionally averaged and spatial nonhomogeneous random cascade process disaggregates above amounts produce patterns across region. generators used disaggregate spatially are product stochastic deterministic factors; latter enable capture systematic gradients exhibited by...

Assessment of rainfall-induced shallow slope failures is important for reducing damage to infrastructures as well the safety people living close hazardous areas. The rainfall intensity-duration thresholds initiation failure (ID thresholds) based on historical data are commonly used assess failure. However, in these slope-stability assessments, critical influence factors triggering often disregarded. Three sets parametric studies were performed through finite-element modeling investigate...

Understanding the hydrological and physical responses of shallow slopes subject to rainfall events is vital for efficiency a warning system setup. In this research, series experiments were undertaken evaluate varying steepness when subjected intensities, periods, inter-storm periods rainfall. An analysis infinite was also develop fundamental understanding rainfall-induced slope failure characteristics. The characterized in infiltration saturation phases. During phase, maximum magnitude water...

Marginal soils, which possess suitable mechanical properties but fail to meet the fine particle content and plasticity index requirements for stabilised earth (MSE) walls, are of particular interest construction industry as a potential replacement granular backfill materials. A numerical analysis unsaturated flow was conducted assess impact each parameter on hydrological conditions in an MSE wall with geocomposite. The studied results indicate that using marginal soil material widespread...

Water loss from broken or leaking pipe networks is still a major water management problem for the Provincial Waterworks Authority (PWA) in Thailand. To reduce this and benefit savings, district metering area (DMA) was applied as measure to control losses at PWA Lop Buri Branch. The DMA divided into 8 zones, covering about 60.47 % of total service area.  A surveillance system set up that compared observed flow rates upper limit warning values each DMA. Comparison results before after...

After flood crisis in Thailand 2011, Department of public works and town planning improved the regulation for urban to include protection plan planning. The aim this paper is present an analysis drainage capacity flood-risk areas integrated Sam Khok district, Pathum Thani province. main cause flooding area overbank from Chao Phraya River. topography, climate, hydrological historical data study are collected analysis. Rational method used analyze 12 canals total 87 by using design rainfall...

The three dominant processes contributing to runoff as proposed by the Dunne diagram are Hortonian overland flow (HOF), (DOF) and subsurface storm (SSF). Using a theoretical perspective, we investigate impact of climate, soil, topography vegetation on catchment water balance probability distribution travel times each generation component in respect connected instantaneous response function (CIRF) including interaction partial area connecting outlet. A simple distributed hydrologic model is...
