A rainfall–runoff (RR) model considering the spatial variation of rainfall, soil infiltration capability and soil storage capacity over a catchment and based on probability distribution functions, is used for rainfall–runoff modelling. The model combines infiltration excess (Horton) and saturation excess (Dunne) mechanisms. Moreover, it is applied to a data sparse catchment. Model parameters of...

6 The available water in a catchment depends on where and when the water is taken. This raises 7 considerable man-made uncertainty in water availability. Partly due to this uncertainty, catchments are 8 over-allocated almost everywhere. The over-allocation problem could be managed more effectively if 9 catchment managers could match users’ rights to the available water. In this paper, I show ho...

Storm Water Management Model (SWMM) is a digital hydrological model which is widely used for the simulation of rainfall-runoff processes in urban catchment. SWMM is a distributed model, which means a study urban catchment needs to be divided into several irregular subcatchments first before simulation. However, most of the existing subcatchments division approaches for the SWMM are not able to ...

Landholders, departmental agencies and other stakeholders have long been involved in knowledge building of the physical elements affecting land use. Often, however, this has been without any accompanying information on social and economic impacts, or systems for exploring catchment trade-off decisions. RIMIS is the concept of a regional management system designed for landscape managers. It has ...

We compare popular school choice mechanisms in terms of children’s access to better schools (ABS) than their catchment area school, in districts with school stratification and where priority is given for residence in the catchment area of the school. In a large market model with two good schools and one bad school, we calculate worst-case and best-case bounds of the Boston Mechanism (BM). We fi...

We investigated the prevalence of infection with hepatitis B virus among adult Vietnamese patients hospitalized for severe Plasmodiumfalciparum malaria. Sera from patients admitted with severe malaria in Ho Chi Minh City, Vietnam, between May 1991 and January 1996 were assayed for hepatitis B surface antigen (HB(s)Ag) by a commercial enzyme-linked immunosorbent assay kit. The overall prevalence...

abstract major of hydrological systems are very complicated and it is not possible to understand them completely, therefore simplification is necessary to understand or control of a part of the system behavior such as water balance relationships. hydrological models are simple structure of complicated systems in water cycle in the nature. the first goal of a hydrological model is function predi...

this contribution determines suitable fingerprinting properties for sediment source discrimination within theamrovan and atary catchments in semnan province, iran. these catchments are representative of a range of geology formations and should therefore provide a meaningful basis for a general assessment of the degree of sediment source discrimination afforded by a range of fingerprint properti...
