Assessment and classification of hydromorphological state of the Breń River

Abstract

The paper presents the classification of the hydromorphological condition of the Breń River according to the River Habitat Survey (RHS). The research of the hydromorphological assessment of the Breń River, which is a right-bank tributary of the Vistula River and almost entirely flows through the area of the Dąbrowa Tarnowska district was conducted in June 2015. The research sites were situated on the border of the Tarnów Plateau and the Vistula Lowland. The Breń River in these sections flows through rural areas used for agricultural purposes with low-density housing. The analysis of qualitative parameters describing the morphological characteristics were based on two synthetic indices of stream quality: Habitat Quality Assesment (HQA) and Habitat Modification Score (HMS). The calculated numerical values of the two indices proved that the sections of the Breń River correspond with the third and fifth class, which means a moderate (III) and very bad (V) hydromorphological condition.

Community engagement for irrigation water management in Lao PDR

Abstract

Sustainable water resources management and community engagement are essential for water security. Referring to the above context, this study proposed to carry out an assessment of community engagement for irrigation water management in the Nam Haad Left Irrigation Project (NHLIP). The household and community level practices and the farmers’ levels of participation in irrigation water management of the NHLIP were carefully considered. From respondents’ responses, the results revealed that a husband-wife partnership plays a remarkable role in irrigation water management of the NHLIP for rice farming. The results also proved that most of the respondents engage with a high participation level in managing irrigation water of the NHLIP project as illustrated by a high score of 3.80 on the five-point Likert scale. To determine the significance of each activity on farmers’ levels of participation in irrigation water management of the NHLIP, a stepwise multiple regression analysis was employed and the standardized regression equation for determining overall participation levels can be presented as: Y = 0.538x 1 + 0.831x 8 + 0.534x 14 + 0.607x 18 + 7.572. Finally, the outcomes of this study indicated the willingness of participation in cooperating and supporting the activities related to the improvement and management of the NHLIP project.

Contract Awards Disparity among Multinational and Indigenous Construction Companies

Abstract

The key players in the construction industry are the construction companies. However, the level of contract awards among multinational and indigenous construction companies in most developing countries is poorly understood. This research aim at determining the level of contract awards among multinational and indigenous construction companies. The research employed a quantitative approach using both primary and secondary method of data collection to achieve the stated objective. Purposive sample techniques were used for collecting both the primary and secondary data. Structured questionnaires were administered to 70 construction professionals and contractors to determine the factors responsible for low indigenous contractor’s participation and award of contracts. Primary and secondary data were collected, and the findings reveal that 65% of the contract awards between 2002 and 2012 were won by the multinational construction companies. While the lack of requisite skill and technical know-how with a percentage severity index (SI) score of 97% was responsible for low indigenous construction companies awards. This result indicates that the multinational construction companies are dominating the construction industry.
