the objectives of this study were to understand the rainfall characteristics of thewind-water erosion crisscross region on the northern loess plateau, china, to provide basisfor the studies on mitigation of soil erosion, estimation on surface water resources andlocal hydrological circle, etc. the liudaogou catchment with representative climatic andhydrologic conditions of wind-water erosion cri...

the main purpose of this study was to explore the factors affecting optimal management of agricultural water in hamadan's area. the statistical population of the study included all hamadan's farmers. a number of 148 farmers were selected randomly through a proportional sampling method in two phases. both questionnaire and interview techniques were used in order to collect data. the empirical an...

This paper aimed to classify the quality of different water sources in Kerala. All major rivers, lakes, and reservoirs are included this study. The is classified into classes based on level pH, Biochemical Oxygen Demand (BOD), Dissolved Oxygen, Electrical Conductivity, concentration Total Coliforms sample. For classification purposes, models proposed. Among these models, Naïve Bayes scored 78.7...

Failures in the water distribution network are some most important factors in water losses, water shortage and dissatisfaction of users and secondary pollutions as well. This research aimed to analyze failure in water distribution networks during 2006-2008, for better water management. Daily failure reports in Ahvaz, Iran distribution network during 2006-2008, were collected from emergency depa...

Ecotourism is growing business in Nepal due to domestic and international visitors. Specifically, natural lakes in Ramsar sites are very potential avenues for boating, scenic beauty and study the aquatic ecosystem. However Eichhornia crassipes has been threatening the beauty, ecosystem and eco-tourism business. This research was objectively carried out to explore income generation from ecotouri...

Introduction: The present study was conducted to implement a simple practical independent quality check of depth dose and isotropy of the Intrabeam™ therapeutic X-ray machine using radiochromic EBT2 film. Material and Methods: Theindependent quality check of 1.5, 3.5, and 5-cm spherical Intrabeam™ applicators was accomplished using particular EBT2 film cutting pieces with internal rounded edge...

The choice among alternative water supply sources is generally based on the fundamental objective of cost minimisation. There is, however, a need to consider sustainability, the environment and social implications in regional water resources planning, in addition to economics. In order to achieve this, multi-criteria decision analysis (MCDA) techniques can be used. There are a large number of M...

Principal component analysis (PCA) based on singular value decomposition (SVD) of hydrological data was tested for water quality assessment. Using two case studies of wasteand drinking water, PCA via SVD was able to find latent variables which explain 80.8% and 83.7% of the variance, respectively. By means of scatter and loading plots, PCA revealed the relationships among samples and hydrochemi...
