Since current water governance patterns mandate cooperation and partnership within and between the actors in the hydrosystems, supplementary models are necessary to distinguish the roles and the rules of indoor actions which is why we extend a theory in the frameworks of philosophy of technology. This analysis is empirically grounded on the problematic hydrosystems of a river in central Iran, Zayandehrud. Following a modernist-holistic-based analysis, it illustrates how values in the water apportionment mechanisms are being reshaped. The article by using the theory of normative practice has scrutinised the tasks and the rules of the old and new water-management systems, Mirab. Subsequently according to such philosophical theory, it has argued that the conflicts over the cases are due to interference of structural and directional norms within them.
Hydraulic heritage systems, both underground and exposed, have been known to be sustainable for millennia. Persian and also Roman aqueducts are examples of such hydrosystems.Their values are often overlooked but they have undeniable advantages: they have functional interconnectedness with their surrounding society and ecology, which sometimes leads to revitalization plans. By using the notion "qualifying role", this paper will raise questions concerning the disregarded functions and early and historical positions of hydraulic heritage systems.This article illustrates the qualifying role of Qanats in urban drainage by describing the skill in their planning and construction. This is shown by a problematic case study in Iran, where the construction of a drainage system modelled on bygone Qanat"s techniques resulted in a dramatic drawdown in the water level of the area soon after construction.
Engineering, as a complex and multidimensional practice of technology development, has long been a source of ethical concerns. These concerns have been approached from various perspectives. There are ongoing debates in the literature of the philosophy of engineering/technology about how to organize an optimized view of the values entailed in technology development processes. However, these debates deliver little in the way of a concrete rationale or framework that could comprehensively describe different types of engineering values and their multi-aspect interrelations in real engineering practices. Approaching engineering values from a meaning-based perspective, as in this paper, can be a reliable method of tackling such a controversial problem. This paper therefore proposes that technology development be considered a systemic normative practice and attempts to provide a comprehensive view of various built-in values, their different origins and features, and a way of prioritizing them in real engineering processes. Studying two cases of the Zayandeh Rood Dam and the Abbasi Dam will lead to practical insights into how to understand norms in technology development and incorporate them into engineering practice.
Abstract-We use the Dichotomous Markov Noise (DMN) model with constant transition rates to describe the dynamics of fluctuations in the water level as a stochastic process, which is imposed on river discharge changes. By applying this model, two different regimes are determined for the long-term behaviour of the river. Based on these regimes, we define two nonparametric classes of the overall increasing/decreasing nature of the water level in the longterm behaviour, which are separated by an exponential steady state regime. In this paper, we develop a nonparametric testing procedure to test exponentially (steady state regime) against an alternative overall decreasing level distribution. The proposed test predicts the long-term regime behaviour of the river. The mathematical tools introduced to handle the problem should be of general use and the testing procedure can be considered as a new mathematical tool in the study of water level dynamics. Under conditions of data austerity and as a case of study, we examine the stochastic characteristics of the Zayandeh Rud 1 River (Isfahan, Iran) water level.
